TightVNC adds a little icon to the system tray when it's running. This icon inverts its colors when Compression and image quality can be tweaked. The UltraVNC viewer supports auto scaling, so it will resize the viewing window For TightVNC, click on the gear icon (settings) and change your picture. Unlike other encodings, Tight encoding is configurable via compression levels and JPEG image quality setting. Enhanced Web browser access.

This option affects only the standard VNC authentication. Encodings are specified separated with spaces, and must thus be enclosed in quotes if more than one is specified. Available encodings, in default order for a remote connection, are "copyrect tight hextile zlib corre rre raw". For a local connection to the same machine , the default order to try is "raw copyrect tight hextile zlib corre rre". Raw encoding is always assumed as a last option if no other encoding can be used for some reason.

This reduces network traffic, but colors may be represented inaccurately. The bgr format is an 8-bit "true color" format, with 2 bits blue, 3 bits green, and 3 bits red. This allows the VNC server to control the colormap.

Level 1 uses minimum of CPU time and achieves weak compression ratios, while level 9 offers best compression but is slow in terms of CPU time consumption on the server side. Use high levels with very slow network connections, and low levels when working over high-speed LANs.

It's not recommended to use compression level 0, reasonable choices start from the level 1. Quality level 0 denotes bad image quality but very impressive compression ratios, while level 9 offers very good image quality at lower compression ratios. Note that the "tight" encoder uses JPEG to encode only those screen areas that look suitable for lossy compression, so quality level 0 does not always mean unacceptable image quality.

Disabling JPEG compression is not a good idea in typical cases, as that makes the Tight encoder less efficient. You might want to use this option if it's absolutely necessary to achieve perfect image quality see also the -quality option. Using cursor shape updates decreases delays with remote cursor movements, and can improve bandwidth usage dramatically.

This option also disables the dot cursor, and disables cursor position updates in non-fullscreen mode. If the client represents itself as able to use multiple formats, the server will choose one. Pixel format refers to the representation of an individual pixel. The most common formats are 24 and 16 bit "true-color" values, and 8-bit "color map" representations, where an arbitrary map converts the color number to RGB values. Encoding refers to how a rectangle of pixels are sent all pixel information in VNC is sent as rectangles.

All rectangles come with a header giving the location and size of the rectangle and an encoding type used by the data which follows. These types are listed below. All clients are required to support this encoding type. Raw is also the fastest when the server and viewer are on the same machine, as the connection speed is essentially infinite and raw encoding minimizes processing time.

CopyRect The Copy Rectangle encoding is efficient when something is being moved; the only data sent is the location of a rectangle from which data should be copied to the current location. Copyrect could also be used to efficiently transmit a repeated pattern. In this encoding, a sequence of identical pixels are compressed to a single value and repeat count. In VNC, this is implemented with a background color, and then specifications of an arbitrary number of subrectangles and color for each.

This is an efficient encoding for large blocks of constant color. This allows for single-byte values to be used, reducing packet size. This is in general more efficient, because the savings from sending 1-byte values generally outweighs the losses from the relatively rare cases where very large regions are painted the same color. Hextile Here, rectangles are split up in to 16x16 tiles, which are sent in a predetermined order. The data within the tiles is sent either raw or as a variant on RRE.

Hextile encoding is usually the best choice for using in high-speed network environments e. Ethernet local-area networks. Zlib Zlib is a very simple encoding that uses zlib library to compress raw pixel data. This encoding achieves good compression, but consumes a lot of CPU time. The UltraVNC viewer supports auto scaling , so it will resize the viewing window automatically, to display the whole screen of the remote server.

Real VNC server 4. Start the server with:. No need to set anything anywhere, on the client or on the server. When you first connect to your server, the resolution is set to whatever is preset on the server side but you can easily change it just by resizing the client window; to any resolution, any crazy, non-standard, ad-hoc resolution you want.

The remote desktop resolution, say KDE, follows your client window resolution smoothly. Please don't confuse auto resolution change with image stretching , alternatively called auto-scaling. This caling is virtually useless, unless you are visually impaired. It works like zoom or looking glass in popular bitmap editors.

It just makes pixels bigger or smaller by stretching the output image. It decrease image quality significantly, if you stretch a lot. What users typically want is real resolution change of the remote session. And that is what I talk about earlier and that is what TigetVNC client is capable, providing server has matching functionality. Auto-resolutioning keeps image sharp at any size.

Downside is it also increases network bandwidth. If you want only viewer, then download only viewer, like vncviewer Beware that with TigerVNC server service starts automatically, silently, in the background, which I strongly detest as a possible security threat. My server is run with no -randr setting at all and just basic -geometry x This low resolution is used only when you first connect, but then you can change the resolution just by resizing the client window.

If you are curious, here is my full VNC server command:. My client setup: TigerVNC client 1. They told me that is because RDP is a real login session, so the screen behaves as you are a common user in the controlled system. VNC simply mirrors the screen. I suggested to create a config on vnc server to allow the screen changing because I know that windows API allow third party sw to programmatically set screen resolution.

I was surprised to find out that setting the resolution on my Raspberry Pi 4 setup with a RealVNC server and client is as simple doing. Anything I tried up to that worked fine. With TightVNC at least if the server windows changes screen resolution then the client automatically changes to match the new resolution. For TightVNC, click on the gear icon settings and change your picture quality to "High" and it works nicely.

I know that this is an old question, but as I found it looking for a way to setup a xrandr with some default sizes -xrandr x,x,x,x,x,x,x did not work for me. To add another mode and resize the window to the new size, I use the following script: The key commands are:. Sign up to join this community. The best answers are voted up and rise to the top.

Also, the installer will install a copy of the TightVNC Web site, and will create shortcuts to most important documentation pages. Any single window or any rectangular screen area can be shared instead of the whole screen. Not scaling, but resize, change controlled pc resolution automatically to match to controller screen. This makes hotkeys such as Shift-Ctrl-Alt-O useful in the full-screen mode.
Teamviewer 101 What users really want is real resolution change of the remote session and so far only TigerVNC is capable to do so, from all of the free viewers. Server for Windows: Adjusted log verbosity levels for log messages generated by the control what is splashtop 2 connection, so that such messages will not overload the log any more. Finally, you can find a number of additional VNC-compatible utilities and packages that can extend the areas where TightVNC can be helpful. This will not work in the applet mode, due to Java security restrictions. The results are similar to those for the kde-hearts session.

That has been fixed. Server for Windows: Fixed the Apply button in the Configuration window - it stayed disabled on editing configuration settings. This should resolve connectivity problems with Ubuntu systems and Vino servers. Viewer for Windows: Fixed hang-up on changing language or keyboard layout. To fix this problem, Windows message handling has been re-designed completely. Viewer for Windows: Fixed priority of preferred encodings.

Previous version could work inefficiently with servers that do not support Tight encoding, because the Viewer could choose uncompressed Raw encoding instead of well-compressed ZRLE. Viewer for Windows: Eliminated character limit on hostnames in the New Connection window. Viewer for Windows: Using correct line ending characters in cross-platform clipboard transfers.

Viewer for Windows: Introduced a number of improvements and fixes in the user interface. That includes new commands in the toolbar and in the system menu, and architectural changes such as restoring the option to start new connections from the same Viewer instance. Viewer for Windows: Adjusting viewer window size on remote desktop resizing.

Viewer for Windows: Other minor improvements and fixes. The changes will not be visible to end user, but developers will appreciate new logging system. There should be no more static methods and global log objects, so it will be easier to reuse separate components in third-party applications.

Now all components work via a simple logging interface or can work without logging at all. Source Code Server and Viewer for Windows : Corrected build problems in various combinations of build configurations and platforms, in both Visual Studio and Visual Studio In the previous version, bit viewer was included by mistake. Installer for Windows: A few text labels and warning messages have been corrected.

Server for Windows: Fixed a bug with uninitialized memory which could lead to random crashes. Viewer for Windows: "Entering full screen" warning now includes an option for not showing it next time. Viewer for Windows: Fixed a problem with -optionsfile command-line option not working correctly unless full path was provided with the options file.

Also, error reporting have been improved when using -optionsfile. Viewer for Windows: Initial image of the remote desktop did not always render correctly in full screen. Now that should be fixed. Installer for Windows: Both bit x86 and bit x64 versions of the installer are available. Server for Windows: Full support for bit systems. Besides obvious benefits of using native architecture, this allows to attach so called "message hooks" to bit applications.

In a simple language, message hooks help at detecting screen activity, so that we can get updates almost immediately instead of polling the complete screen once per second or so. This makes screen reading ultra-fast in all supported versions of Windows, from Windows to Windows 7. Server for Windows: Improved performance when sharing a desktop with Windows Aero enabled.

With Aero, each screen reading operation is expensive, and we can improve performance by reading more pixels in less operations. Server for Windows: Improved logging. Most importantly, new version reports all incoming connections to Windows Event Log. Also, logging to text files has been improved - the service writes to the same log file from all its child processes.

There's always just one log file, so it's easier to locate an error message or e-mail the log to technical support service. Server for Windows: New option to configure extra ports mapped to arbitrary screen areas. If a client connects to such an extra port, it will be shown the corresponding part of the screen only. Server for Windows: New command-line options to share full desktop, primary monitor, selected monitor, a window, or an arbitrary rectangular area.

Server for Windows: Optimized video processing for specific window classes. You can tell TightVNC to treat certain windows as video by providing a list of window class names. Once a matching window is detected, its contents will be sent to clients continuously, with minimum delays. Viewer for Windows: Native bit version for improved performance in x64 systems.

Viewer for Windows: Fast screen drawing and optimized decoders. Viewer for Windows: Desktop scaling that can be easily controlled via the toolbar. Viewer for Windows: New feature to pause screen updates. You can freeze the remote desktop at any moment, e.

Viewer for Windows: Unicode-enabled compilation. Unlike previous versions of TightVNC Viewer, this one fully supports Unicode and has no problems with using multiple national languages in user input, screen labels, file names etc. Viewer for Windows: Easily reusable source code. The viewer has been redesigned from the scratch. The primary design goal was to develop a "remote control SDK" and build the viewer on top of it. And we've done just that.

So not only we provide new version of the viewer, but we also give software developers an easy way to add remote control functionality to their products both free and commercial. The resulting SDK has a simple interface which hides all the complexity of the underlying protocols. Java Viewer: Desktop scaling that can be easily controlled via the toolbar. You can restrict the number of colors to save traffic, or prefer a rich-color format to maximize image quality.

From the GUI, you can choose a color mode with 8, 64, , , colors, or select the server's native number of colors. However, the core component supports any color format as allowed by the RFB protocol except palette-based modes. Java Viewer: Corrected negotiation of the protocol version. New version should be able to connect to Mac OS X.

Java Viewer: Various minor fixes and improvements. This problem affected Windows systems only. Server for Windows: CPU use was significantly reduced in idle periods when there are no users connected. Server for Windows: Fixed a problem which resulted in wrong color rendering in "big-endian" viewers e. PowerPC-based Mac viewers.

Server for Windows: Fixed rendering of semi-transparent mouse cursors. Previously, big black boxes could be seen instead of such cursors. Server for Windows: Introducing new "error handler" which allows saving memory dumps on critical errors.

Server for Windows: In systems with swapped left and right mouse buttons, remote mouse events will be adjusted accordingly. As a result, the remote mouse should work just like the local one. Server for Windows: Fixed a number of problems led to errors on setting service passwords from the installer. Server for Windows: Not allowing to enter administrative passwords longer than eight characters.

Previous versions used only the first eight characters anyway but it was possible to enter longer passwords and that could confuse users who did not know about the limitation. Server for Windows: Fixed a problem with injecting lowercase characters when CapsLock was on on the server.

Previous version generated uppercase characters when CapsLock was on, regardless of the Shift state. It looks like there is a bug in Windows so we could do nothing better than to cook a workaround specifically for this case. Server for Windows: Fixed clipboard handling with multiple client connections. Previously, clipboard contents might not be sent to particular clients in certain circumstances.

Server for Windows: Adjusted log verbosity levels for log messages generated by the control interface connection, so that such messages will not overload the log any more. Server for Windows: Made minor adjustments in the user interface.

Specifically, the "About Viewer for Windows: Fixed a number of problems with saving and restoring connection options. Viewer for Windows: Fixed user interface logic in the Options window. There were incorrect dependencies between compression-related controls. Viewer for Windows: Improved phrasing for a number of error messages and log records in the file transfer module. Source Code: Visual Studio is now supported, upgraded solution and project files are included in the source distribution.

Versions for Visual Studio are included as well. New version should be fully compatible with Windows desktop scaling. This fix was developed for TightVNC 2. Server and Viewer for Windows: More fixes have been made to solve problems with clipboard transfers. Both server and viewer could send question characters instead of non-ASCII symbols if current input language did not match the text encoding.

These fixes complement related changes introduced in version 2. After creating five backup copies, it failed to rename old files and just overwrote the most recent log file. Viewer for Windows: Server-to-client clipboard transfers have been fixed. Multiple files and directories can be copied at once, directories are processed recursively. Data compression is used to speed-up copying. Files can be renamed or removed, new directories can be created. File sizes are not limited by 4 Gb any more.

Server for Windows: Implemented new architecture which separates service code from the user interface. This enables service-mode operation under Windows Vista and Windows 7. Also, this fixes all known problems with multi-user features of modern Windows systems like Fast User Switching and Terminal Services. Server for Windows: Screen updates have become reliable. If something went wrong and the picture in the viewer is garbled, incomplete or outdated, it will be recovered in reasonable time.

There should be no more hidden menus or destructive window movements. If fast update detection methods fail, full-screen polling will keep updates going. Server for Windows: Featuring new secure administrative interface. Control interface can be optionally protected with a password to make sure users cannot reconfigure or shut down the service unless they know the password or have administrator privileges.

Server for Windows: There should be no more confusion between "default settings" and "user settings". In TightVNC 2. The "Configure Server for Windows: Featuring IP-based access control for incoming connections. You can even test the rules on specific IP addresses, prior to applying new rules. Installer: TightVNC 2. It's smarter and more efficient. It tries to prevent reboots whenever possible. It invites to set passwords so that TightVNC Server would be ready to work right at the moment of finishing the installation.

Finally, the complete self-installing TightVNC package both server and viewer parts, and the uninstall tool is only kilobytes in size. Server and Viewer for Windows: Keyboard handling has been improved. Older versions of TightVNC had problems with passing characters that do not fit in the Latin-1 code space. This list of changes is not full.

TightVNC Server 2. It does not include old TightVNC 1. So the right answer to the "What's New? TightVNC 1. Disabling file transfers if current user is unknown or nobody is logged in. Windows Server: Fixed rendering problems when multiple CopyRects were combined with normal updates.

That could caused distortions that never updated even with full-screen polling active. Windows Server: Added new "-silent" command-line option which modifies the behavior of -install, -reinstall and -remove options and makes them not show informational windows on successful execution. Note that -silent should precede other respective options in the command line. A specially modified VNC server could currupt the heap of the connected viewer causing its crash or malfunction.

Now we save unsuccessful connections too so that users would not ever have to re-type server names after connection failures. Also, several other enhancements were made to the code which handles the list of recent connections. Windows Viewer: Fixed a bug with not loading passwords from saved. Windows Viewer: Fixed problems under Windows Vista where Windows taskbar could remain visible above the full-screen window.

Windows Viewer: Fixed a bug with not saving log file name correctly on using the Browse button. Windows Viewer: Usability improvements in the "New Connection" dialog. Windows Packaging: Improved installer and uninstall utility. In this version, self-installing executable will not try to install service in Windows Vista. Improved uninstall program always removes the WinVNC service if it was previously installed.

Java viewer: Fixed a bug with ignoreCursorUpdates option in bit color mode caused the viewer to disconnect. Thanks to Damien Mascre for pointing out the issue. Java viewer: PORT parameter is not required any more, now it defaults to Java viewer: Do not defer update requests by default, to minimize delays in screen updates.

Java viewer: Improvements in reporting statistics on disconnect. Other minor improvements and bugfixes. All platforms: Made "host:port" parsing maximally compatible with VNC4. Interpreting a number in host names like somehost as an actual port number if it's not in the range [ Windows Server: Various user interface enhancements - changes in GUI labels, tray icon with a red border when incoming connections are not possible for any reason, more information in the tray icon tip, smarter logic in displaying the Properties dialog, and more.

Windows Server: Slightly improved handling of passwords. One of the notable changes is that now it's enough to enter a view-only password without providing primary password. The changes were ported from VNC 4. There are reports that this solves the problem with greyed username and password fields on Windows Server bug Windows Server: Bugfix for the bug attempt to restart the machine remotely via TightVNC led to disconnect if there was some non-saved data, and further connections were rejected.

Windows Viewer: Multiple selection now works in file transfers, thanks to developers at Novell and personally Rohit Kumar. Windows Viewer: The viewer terminated silently when the server dropped connection right after accepting it. Now we report such errors. Also, all required libraries are now included within the source distribution. Java viewer: Implemented scaling, either with a fixed scaling factor or automatic.

From the other side, the viewer remains compatible with Java 1. Scaling can be enabled with new "Scaling Factor" parameter but cannot be controlled from the GUI yet. Java viewer: Disabled focus traversal keys under JVMs 1. This fixes the problem with not sending Tab key events to the VNC server. Java viewer: Fixed wrong pixel format interpretation at decoding RichCursor pseudo-encoding local cursor could be rendered in wrong colors.

Other improvements and bugfixes, see ChangeLog files within the distribution for more details. Win32 server: Improved layout and functionality of the Properties dialog. Win32 server: More accurate password handling - now the server code tries to distinguish between "empty" and "unset" passwords better.

Win32 server: New -shareall, -shareprimary and -sharearea command-line options, working similarly to the -sharewindow option. Win32 server: Fixed problems with restoring desktop wallpaper. Win32 viewer: Fixed bug with not setting proper size of the viewer window. Unix server: Port numbers are now calculated modulo with vncviewer's -listen option. That makes it possible to listen on TCP ports under Java viewer: Automatic encoding selection based on measuring current network throughput.

Win32 server: Removed the code for "desktop optimizations" that was rather harmful than useful. Hopefully, this should fix problems with crashing Delphi applications. Also this should prevent settings like font smoothing always set to true on disconnect. Win32 server: Fixed the issue with port number edit boxes that were labeled incorrectly in the Properties dialog. Win32 server: Disallowing clipboard transfers in view-only mode. Win32 server: Fixed the problem with wallpaper being removed only after completing the initial screen transmission.

Win32 server: Minor improvements in the File Transfers dialog. Win32 server: More context help messages in Properties and File Transfers dialogs. Unix server: Fixed a serious bug with sending cursor updates when there was no FrameBufferUpdateRequest from that client. Unix server: Fixed problems with building Xvnc on modern linux distributions, such as Fedora Core 3. Unix server: Disallowing clipboard transfers for view-only clients. Also, current mirror driver status is shown in the Hooks tab.

Win32 server: The option "Don't use mirror display driver even if available" is now functional. Win32 server: New option "Blank screen on client connections". When set and new client connects, the server's monitor is forced to go to power saving mode. Win32 server: Fixed bugs with saving certain settings in the registry, and bugs with setting default values when the registry is not writable. Win32 server: Fixed a problem with one-pixel mouse offset.

Win32 server: Fixed problems with inter-thread locking, this should solve "Unhandled message type received" problems. Win32 server: Fixed a problem with the setting "Block remote input on local activity", it was not working with DLL hooks disabled. Win32 server: Fixed various problems with file transfer implementation.

Win32 viewer: New "Auto" scaling mode. In this mode, the viewer scales remote desktop to fit local window or screen size. If the window size is changed, the scaling factor is adjusted automatically. Win32 viewer: Now the viewer checks server's capabilities and does not ever use non-standard protocol messages not supported by the server. This change affects file transfers only, as other features do not use non-standard protocol messages..

Java viewer: New "scale remote cursor" option has been added. It allows to reduce or enlarge cursor image in the full-control mode. Java viewer: A cursor repaint problem has been fixed. Using the mirror driver greatly increases the speed and reliability of updates, and also desreases CPU utilization on the server.

Win32 server: New polling algorithm has been implemented. It's similar to that found in x0rfbserver. New algorithm uses minimum CPU time when there are no changes on the screen, and detects major changes very quickly, resulting in greatly improved responsiveness on the client side. Win32 server: Improved methods for filtering screen changes that actually do not change anything. New algorithm not only works faster, but it also detects changes much more accurately, leaving less work to encoders.

Win32 viewer: A special mode for Unix users has been implemented: when ScrollLock is on, the viewer will send Meta on pressing Alt keys. Win32 server: Fixed a problem with view-only clients that were enabled full control on just opening the Properties dialog of the server. Win32 server: It should not ever hang any more on changing ports or the LoopbackOnly setting. Win32 server: The problem with not saving Query Settings has been fixed.

Win32 server: The polling mode "on event received only" has been fixed - it did not work correctly in previous version. Win32 server: Fixed a number of issues with mouse handling, including that annoying problem with pointer jumping on slow connections. Win32 server: Applied a bugfix from HorizonLive solving the problem with crashes or incorrect operation after color depth changes on the server's desktop. Win32 viewer: It does not crash any more on entering long passwords in the authentication window.

Win32 viewer: Positioning and resizing logic of the viewer window has been improved. Win32 viewer: Now the viewer chooses more reasonable file names for saved. Win32 viewer: In the full-screen mode, the viewer allows other windows to be shown above the remote desktop. This makes hotkeys such as Shift-Ctrl-Alt-O useful in the full-screen mode. Unix version: A number of bugfixes -- copying clipboard to non-authenticated clients in Xvnc, delayed cursor shape updates in Xvnc, and crashing on switching between KDE virtual desktops in vncviewer.

Other changes, see ChangeLog files within the distribution for more details. Version 3. Win32 version: Built-in Java viewer was absent in the previous development version; now it's available again. Win32 version: Now the server does not crash on remote Ctrl-Alt-Del events, and on changing display modes.

Win32 version: A problem with reinstalling the service has been fixed WinVNC -reinstall command-line option. In previous versions, reinstalling the service could fail if a user did not close "Service unregistered" message box within a few seconds. A warning is shown instead. Win32 version: CopyRect handling in the server has been fixed, the CopyRect encoding is enabled again.

Win32 version: The Advanced Properties dialog of the server has been removed. The controls of that dialog has been moved to tabs in the Properties dialog. Win32 version: Context help in the server's Properties dialog has been implemented although not all descriptions are ready yet.

There was some progress on supporting pluggable encryption and authentication methods, in both Win32 and Unix versions, and in the Java viewer. Improved GUI of the viewer featuring toolbar, hotkeys, pre-set connection profiles, more configuration options, context help in dialogs, and more.

Finally, the viewer remembers all per-connection and global settings in the registry. File transfers between viewer and server machines. Support for RFB protocol version 3. A possibility to turn off hooking via VNCHooks. Together with fixing this bug, the whole authentication logic in the server code has been redesigned. This change should solve the problem with unloading the registry on logout, when WinVNC is running as a service.

Win32 version: Problems with "QuerySetting" and "QueryTimeout" options have been fixed -- the settings could be copied from user configuration to default settings without user's intention. Win32 version: A long-standing bug has been fixed -- the logic to handle retries after authentication failures was flawed, and used to delete the same object twice under certain conditions.

Win32 version: Now it's possible to specify port numbers with the winvnc -connect option, using the "host::port" format. Also, providing a -connect option without arguments now brings up the "Add New Client" dialog. Unix version: New "Request refresh" button has been implemented in the viewer's F8 popup menu. Unix version: New vncpasswd -f command-line option has been implemented. It allows providing passwords on stdin and writes encrypted passwords to stdout.

In addition, the password file name "-" now denotes stdout. Finally, a buffer overflow has been fixed in vncpasswd -- it could be caused by a long file name in the command line. Unix version: A patch to fix input focus problems in the X11 viewer has been applied, from Greg Breland.

Unix version: A problem with incorrect port interpretation has been fixed, in the vncviewer's -tunnel option handling. Thanks to Clark Sessions. Java viewer: A modification from Bernd Krueger-Knauber has been accepted, to pass through X keysyms for foreign currencies. Java viewer: The problem with initial keyboard focus not set to the desktop on some JVMs has been fixed.

Now the servers support two passwords -- one to allow full control, another to restrict remote keyboard and mouse input. Win32 version: The password reset problem has been solved. In versions starting from 1. Win32 version: New "-reload" command-line option has been implemented in Win32 server.

It forces the running instance to reload the registry settings. Unix version: New "-x11cursor" option has been implemented in vncviewer; a patch from Peter Astrand. This option allows using a real X11 cursor with Xstyle cursor shape updates, disables the dot cursor, and disables cursor position updates in non-fullscreen mode. Unix version: New "RunCommand" command to customize the X11 vncviewer popup menu has been implemented; a patch from Peter Astrand. Unix version: Several patches from Debian Linux have been applied.

This should fix a number of bugs and improve building on some platforms supported by Debian Linux. New PointerPos encoding and cursor shape updates both minimize bandwidth requirements and greatly improve responsiveness of the mouse pointer, while still allow to track correct pointer position in all situations. Unix and Win32 versions: In all the places where display numbers had to be used, now it's easy to use port numbers as well.

The viewers now allow to use new "hostname::port" syntax, in addition to the traditional "hostname:display" format. The same new syntax can be used in the "Add new client" dialog of Win32 server. Each user can have a different password—probably a good idea for security and accountability reasons. This icon inverts its colors when sessions are in progress.

Right-clicking the icon allows you to set the following options:. Over dial-up, you should stick to the traditional VNCViewer.

Optional JPEG compression to help speed up slower connections.

General compression levels can be modified depending on connection speed and CPU power. Compression algorithms are new in TightVNC, which performs better over slower connections than the traditional compression algorithms in the standard version of VNC. The Java viewer has been improved to support bit color. Right-clicking the icon allows you to set the following options: Add New Client —Outgoing connections can be made to a viewer on another viewer that is in Listen mode.

This fix was developed for TightVNC 2. Server and Viewer for Windows: More fixes have been made to solve problems with clipboard transfers. Both server and viewer could send question characters instead of non-ASCII symbols if current input language did not match the text encoding.

These fixes complement related changes introduced in version 2. After creating five backup copies, it failed to rename old files and just overwrote the most recent log file. Viewer for Windows: Server-to-client clipboard transfers have been fixed. Multiple files and directories can be copied at once, directories are processed recursively. Data compression is used to speed-up copying.

Files can be renamed or removed, new directories can be created. File sizes are not limited by 4 Gb any more. Server for Windows: Implemented new architecture which separates service code from the user interface. This enables service-mode operation under Windows Vista and Windows 7. Also, this fixes all known problems with multi-user features of modern Windows systems like Fast User Switching and Terminal Services. Server for Windows: Screen updates have become reliable.

If something went wrong and the picture in the viewer is garbled, incomplete or outdated, it will be recovered in reasonable time. There should be no more hidden menus or destructive window movements. If fast update detection methods fail, full-screen polling will keep updates going. Server for Windows: Featuring new secure administrative interface. Control interface can be optionally protected with a password to make sure users cannot reconfigure or shut down the service unless they know the password or have administrator privileges.

Server for Windows: There should be no more confusion between "default settings" and "user settings". In TightVNC 2. The "Configure Server for Windows: Featuring IP-based access control for incoming connections.

You can even test the rules on specific IP addresses, prior to applying new rules. Installer: TightVNC 2. It's smarter and more efficient. It tries to prevent reboots whenever possible. It invites to set passwords so that TightVNC Server would be ready to work right at the moment of finishing the installation. Finally, the complete self-installing TightVNC package both server and viewer parts, and the uninstall tool is only kilobytes in size. Server and Viewer for Windows: Keyboard handling has been improved.

Older versions of TightVNC had problems with passing characters that do not fit in the Latin-1 code space. This list of changes is not full. TightVNC Server 2. It does not include old TightVNC 1. So the right answer to the "What's New?

TightVNC 1. Disabling file transfers if current user is unknown or nobody is logged in. Windows Server: Fixed rendering problems when multiple CopyRects were combined with normal updates. That could caused distortions that never updated even with full-screen polling active. Windows Server: Added new "-silent" command-line option which modifies the behavior of -install, -reinstall and -remove options and makes them not show informational windows on successful execution.

Note that -silent should precede other respective options in the command line. A specially modified VNC server could currupt the heap of the connected viewer causing its crash or malfunction. Now we save unsuccessful connections too so that users would not ever have to re-type server names after connection failures.

Also, several other enhancements were made to the code which handles the list of recent connections. Windows Viewer: Fixed a bug with not loading passwords from saved. Windows Viewer: Fixed problems under Windows Vista where Windows taskbar could remain visible above the full-screen window. Windows Viewer: Fixed a bug with not saving log file name correctly on using the Browse button.

Windows Viewer: Usability improvements in the "New Connection" dialog. Windows Packaging: Improved installer and uninstall utility. In this version, self-installing executable will not try to install service in Windows Vista. Improved uninstall program always removes the WinVNC service if it was previously installed. Java viewer: Fixed a bug with ignoreCursorUpdates option in bit color mode caused the viewer to disconnect.

Thanks to Damien Mascre for pointing out the issue. Java viewer: PORT parameter is not required any more, now it defaults to Java viewer: Do not defer update requests by default, to minimize delays in screen updates. Java viewer: Improvements in reporting statistics on disconnect. Other minor improvements and bugfixes. All platforms: Made "host:port" parsing maximally compatible with VNC4.

Interpreting a number in host names like somehost as an actual port number if it's not in the range [ Windows Server: Various user interface enhancements - changes in GUI labels, tray icon with a red border when incoming connections are not possible for any reason, more information in the tray icon tip, smarter logic in displaying the Properties dialog, and more. Windows Server: Slightly improved handling of passwords. One of the notable changes is that now it's enough to enter a view-only password without providing primary password.

The changes were ported from VNC 4. There are reports that this solves the problem with greyed username and password fields on Windows Server bug Windows Server: Bugfix for the bug attempt to restart the machine remotely via TightVNC led to disconnect if there was some non-saved data, and further connections were rejected.

Windows Viewer: Multiple selection now works in file transfers, thanks to developers at Novell and personally Rohit Kumar. Windows Viewer: The viewer terminated silently when the server dropped connection right after accepting it. Now we report such errors. Also, all required libraries are now included within the source distribution. Java viewer: Implemented scaling, either with a fixed scaling factor or automatic. From the other side, the viewer remains compatible with Java 1. Scaling can be enabled with new "Scaling Factor" parameter but cannot be controlled from the GUI yet.

Java viewer: Disabled focus traversal keys under JVMs 1. This fixes the problem with not sending Tab key events to the VNC server. Java viewer: Fixed wrong pixel format interpretation at decoding RichCursor pseudo-encoding local cursor could be rendered in wrong colors. Other improvements and bugfixes, see ChangeLog files within the distribution for more details.

Win32 server: Improved layout and functionality of the Properties dialog. Win32 server: More accurate password handling - now the server code tries to distinguish between "empty" and "unset" passwords better. Win32 server: New -shareall, -shareprimary and -sharearea command-line options, working similarly to the -sharewindow option. Win32 server: Fixed problems with restoring desktop wallpaper. Win32 viewer: Fixed bug with not setting proper size of the viewer window. Unix server: Port numbers are now calculated modulo with vncviewer's -listen option.

That makes it possible to listen on TCP ports under Java viewer: Automatic encoding selection based on measuring current network throughput. Win32 server: Removed the code for "desktop optimizations" that was rather harmful than useful. Hopefully, this should fix problems with crashing Delphi applications.

Also this should prevent settings like font smoothing always set to true on disconnect. Win32 server: Fixed the issue with port number edit boxes that were labeled incorrectly in the Properties dialog. Win32 server: Disallowing clipboard transfers in view-only mode. Win32 server: Fixed the problem with wallpaper being removed only after completing the initial screen transmission.

Win32 server: Minor improvements in the File Transfers dialog. Win32 server: More context help messages in Properties and File Transfers dialogs. Unix server: Fixed a serious bug with sending cursor updates when there was no FrameBufferUpdateRequest from that client. Unix server: Fixed problems with building Xvnc on modern linux distributions, such as Fedora Core 3.

Unix server: Disallowing clipboard transfers for view-only clients. Also, current mirror driver status is shown in the Hooks tab. Win32 server: The option "Don't use mirror display driver even if available" is now functional. Win32 server: New option "Blank screen on client connections". When set and new client connects, the server's monitor is forced to go to power saving mode. Win32 server: Fixed bugs with saving certain settings in the registry, and bugs with setting default values when the registry is not writable.

Win32 server: Fixed a problem with one-pixel mouse offset. Win32 server: Fixed problems with inter-thread locking, this should solve "Unhandled message type received" problems. Win32 server: Fixed a problem with the setting "Block remote input on local activity", it was not working with DLL hooks disabled.

Win32 server: Fixed various problems with file transfer implementation. Win32 viewer: New "Auto" scaling mode. In this mode, the viewer scales remote desktop to fit local window or screen size. If the window size is changed, the scaling factor is adjusted automatically. Win32 viewer: Now the viewer checks server's capabilities and does not ever use non-standard protocol messages not supported by the server.

This change affects file transfers only, as other features do not use non-standard protocol messages.. Java viewer: New "scale remote cursor" option has been added. It allows to reduce or enlarge cursor image in the full-control mode. Java viewer: A cursor repaint problem has been fixed.

Using the mirror driver greatly increases the speed and reliability of updates, and also desreases CPU utilization on the server. Win32 server: New polling algorithm has been implemented. It's similar to that found in x0rfbserver. New algorithm uses minimum CPU time when there are no changes on the screen, and detects major changes very quickly, resulting in greatly improved responsiveness on the client side.

Win32 server: Improved methods for filtering screen changes that actually do not change anything. New algorithm not only works faster, but it also detects changes much more accurately, leaving less work to encoders. Win32 viewer: A special mode for Unix users has been implemented: when ScrollLock is on, the viewer will send Meta on pressing Alt keys. Win32 server: Fixed a problem with view-only clients that were enabled full control on just opening the Properties dialog of the server.

Win32 server: It should not ever hang any more on changing ports or the LoopbackOnly setting. Win32 server: The problem with not saving Query Settings has been fixed. Win32 server: The polling mode "on event received only" has been fixed - it did not work correctly in previous version. Win32 server: Fixed a number of issues with mouse handling, including that annoying problem with pointer jumping on slow connections.

Win32 server: Applied a bugfix from HorizonLive solving the problem with crashes or incorrect operation after color depth changes on the server's desktop. Win32 viewer: It does not crash any more on entering long passwords in the authentication window. Win32 viewer: Positioning and resizing logic of the viewer window has been improved.

Win32 viewer: Now the viewer chooses more reasonable file names for saved. Win32 viewer: In the full-screen mode, the viewer allows other windows to be shown above the remote desktop. This makes hotkeys such as Shift-Ctrl-Alt-O useful in the full-screen mode. Unix version: A number of bugfixes -- copying clipboard to non-authenticated clients in Xvnc, delayed cursor shape updates in Xvnc, and crashing on switching between KDE virtual desktops in vncviewer.

Other changes, see ChangeLog files within the distribution for more details. Version 3. Win32 version: Built-in Java viewer was absent in the previous development version; now it's available again. Win32 version: Now the server does not crash on remote Ctrl-Alt-Del events, and on changing display modes. Win32 version: A problem with reinstalling the service has been fixed WinVNC -reinstall command-line option.

In previous versions, reinstalling the service could fail if a user did not close "Service unregistered" message box within a few seconds. A warning is shown instead. Win32 version: CopyRect handling in the server has been fixed, the CopyRect encoding is enabled again. Win32 version: The Advanced Properties dialog of the server has been removed. The controls of that dialog has been moved to tabs in the Properties dialog. Win32 version: Context help in the server's Properties dialog has been implemented although not all descriptions are ready yet.

There was some progress on supporting pluggable encryption and authentication methods, in both Win32 and Unix versions, and in the Java viewer. Improved GUI of the viewer featuring toolbar, hotkeys, pre-set connection profiles, more configuration options, context help in dialogs, and more. Finally, the viewer remembers all per-connection and global settings in the registry. File transfers between viewer and server machines.

Support for RFB protocol version 3. A possibility to turn off hooking via VNCHooks. Together with fixing this bug, the whole authentication logic in the server code has been redesigned. This change should solve the problem with unloading the registry on logout, when WinVNC is running as a service. Win32 version: Problems with "QuerySetting" and "QueryTimeout" options have been fixed -- the settings could be copied from user configuration to default settings without user's intention.

Win32 version: A long-standing bug has been fixed -- the logic to handle retries after authentication failures was flawed, and used to delete the same object twice under certain conditions. Win32 version: Now it's possible to specify port numbers with the winvnc -connect option, using the "host::port" format.

Also, providing a -connect option without arguments now brings up the "Add New Client" dialog. Unix version: New "Request refresh" button has been implemented in the viewer's F8 popup menu. Unix version: New vncpasswd -f command-line option has been implemented. It allows providing passwords on stdin and writes encrypted passwords to stdout.

In addition, the password file name "-" now denotes stdout. Finally, a buffer overflow has been fixed in vncpasswd -- it could be caused by a long file name in the command line. Unix version: A patch to fix input focus problems in the X11 viewer has been applied, from Greg Breland. Unix version: A problem with incorrect port interpretation has been fixed, in the vncviewer's -tunnel option handling.

Thanks to Clark Sessions. Java viewer: A modification from Bernd Krueger-Knauber has been accepted, to pass through X keysyms for foreign currencies. Java viewer: The problem with initial keyboard focus not set to the desktop on some JVMs has been fixed.

Now the servers support two passwords -- one to allow full control, another to restrict remote keyboard and mouse input. Win32 version: The password reset problem has been solved. In versions starting from 1. Win32 version: New "-reload" command-line option has been implemented in Win32 server. It forces the running instance to reload the registry settings. Unix version: New "-x11cursor" option has been implemented in vncviewer; a patch from Peter Astrand.

This option allows using a real X11 cursor with Xstyle cursor shape updates, disables the dot cursor, and disables cursor position updates in non-fullscreen mode. Unix version: New "RunCommand" command to customize the X11 vncviewer popup menu has been implemented; a patch from Peter Astrand. Unix version: Several patches from Debian Linux have been applied.

This should fix a number of bugs and improve building on some platforms supported by Debian Linux. New PointerPos encoding and cursor shape updates both minimize bandwidth requirements and greatly improve responsiveness of the mouse pointer, while still allow to track correct pointer position in all situations.

Unix and Win32 versions: In all the places where display numbers had to be used, now it's easy to use port numbers as well. The viewers now allow to use new "hostname::port" syntax, in addition to the traditional "hostname:display" format.

The same new syntax can be used in the "Add new client" dialog of Win32 server. In the server, now it's equally easy to set display and port numbers. This improves bandwidth usage while the image quality remains satisfactory in most cases. In clients, JPEG compression is now enabled by default, because usually it's a reasonable choice. To prevent viewers from requesting JPEG compression, new -nojpeg option can be used. Win32 version: Major enhancements in layout and functionality of the dialog boxes.

The viewer now accepts a port number after the -listen command-line option, an improvement from RealVNC 3. Win32 version: Eliminated high CPU usage on the server before sending cursor shape updates. Unix version: Bugfix for Xvnc's -localhost and -interface options that were broken on many systems, thanks to Luke Mewburn for the bugfix. Xvnc -version command-line option is now supported. Tight encoding is now documented in rfbproto. Java viewer: Implemented new buttons "Login again" and "Close window" near the disconnect or error messages in the applet mode, and introduced new "Offer Relogin" parameter to control this improvement.

Thanks to Peter Astrand for the initial version of the "Login again" patch. This will not work in the applet mode, due to Java security restrictions. Java viewer: Extra. Also, an example HTML page has been prepared, to simplify installation under a standalone Web server.

Any single window or any rectangular screen area can be shared instead of the whole screen. The position and dimensions of the shared screen area can be changed dynamically, and client windows will adjust their dimensions on the fly. The user interface to choose shared screen area is very intuitive and easy to use. Screen resolution changes won't cause WinVNC to disconnect clients any more but changes in screen color format still result in disconnects, this will be fixed later.

It's possible to make WinVNC ignore remote inputs when local mouse or keyboard is in use. Remote events will be re-enabled after a specified timeout 3 seconds by default. There may be other changes I forgot to mention.

It just re-uses the port if the display number is not set to "Auto". One visible effect of this change is that the delay between starting up and showing the icon is greatly reduced. Unix version: Fixed the bug which prevented the vncpasswd utility from setting correct permissons on the passwd file.

Unix version: Fixed a repeated challenge replay attack vulnerability, bugtraq id Unix version: Improved scrolling in the full-screen mode, modified patch from Ville Herva. Minor cleanups. Win32 version: Enabled remote upgrade in the installation script. Also, the installer will install a copy of the TightVNC Web site, and will create shortcuts to most important documentation pages. Win32 version: Added support for the NewFBSize pseudo-encoding allowing to change framebuffer geometry on the fly on server's request.

Win32 version: The viewer now tries to preserve the size and position of the desktop window after applying new connection options. Unix version: Applied Xvnc -viewonly patch from Ehud Karni. Unix version: Bug fixed: Xvnc failed to reset compression level and JPEG image quality on reading lists of encodings supported by clients. Unix version: Made the viewer handle XCursor encoding operating on the framebuffer instead of setting new cursors directly in X.

Unix version: Applied a number of porting fixes from Ki Networks, Inc. This feature works only if JVM security manager allows access to the local filesystem, which is usually true only when the viewer is used as a standalone application or if the viewer applet is cryptographically signed.

New "Record" button will appear in the button panel if this feature is enabled. Other minor fixes and cleanups. This should eliminate crashes when using x2vnc and win2vnc client programs. Win32 version: a problem with listening viewer was fixed. Initiating multiple non-shared connections could crash the viewer application.

Win32 version: real passwords are never placed into the password text control in the WinVNC Properties dialog any more. This should prevent grabbing plain-text passwords from that text control. Win32 version: logging on errors was improved to provide better diagnosis for errors, especially for those causing the message "Connection closed" right after authentication.

Win32 version: handling of log files was improved. Win32 version: a problem with reporting error messages in the listening viewer was fixed. Win32 version: reporting incorrect statistics in the Tight encoder was fixed. Unix version: applied patch from Ki Networks, Inc. Unix version: added a possibility to denote standard input with the "-" file name instead of a real password file name.

Unix version: fixed a bug causing vncpasswd utility work incorrectly when a file name argument was given in the command line. Unix version: applied patch to solve keyboard focus problems in the full-screen vncviewer, from Peter Astrand. The patch does not seem to solve all the issues, but definitely makes things better.

New grabKeyboard resource was added to control full-screen mode behavior. Java viewer: new "Show Offline Desktop" parameter was added to make the desktop still visible even after the remote side has closed connection. Java viewer: error messages were made much more meaningful.

Java viewer: keyboard focus problems were fixed. This should prevent opening new windows e. Options or Clipboard behind the active authenticator or desktop window. Older versions had to wait while one client finishes his transaction, only then they served new client connections, thus making easy denial-of-service attacks possible. Unix and Win32 versions: updated built-in Java viewer, see details below. Win32 version: Added support for mouse wheel events.

Wheel mouse support is fully compatible and interoperable with Unix version where this feature was available for a long time. Win32 version WinVNC : The -connect command-line option now accepts a display number after a hostname. Win32 version: Creating associations for. Most important new features include: support for bit colors, JPEG support in Tight encoding, RFB Bell message support, new "Refresh" button, a possibility to operate in a separate scrollable window, dynamic view-only mode.

Many more changes were introduces, see the ChangeLog for more information. Please note that new Java viewer class names were changed, e. Unix version: a number of changes in the vncserver script, e. Unix version: zlib library was removed from the core X sources. In the former case, build procedure would include additional "make libs" step. System libraries will be linked dynamically, libraries included in the source archive will be linked in statically.

Unix version now includes comprehensive manual pages for vncviewer, vncserver, Xvnc, vncconnect and vncpasswd programs. The vncinstall script in the source distribution now accepts one more parameter allowing to specify where to install manual pages. Unix version Xvnc : several bugfixes, e. Unix version is no more distributed as patches to a standard VNC release.

This is because patches cannot handle changes in binary files and handle file removals very inefficiently. Win32 server: changes in layout and text of the Advanced Preferences dialog. Unix viewer: Now viewer window would be raised on beep bell event, unless new -noraiseonbeep option is provided in the command line or "raiseOnBeep" resource set to False.

Win32 viewer: added support for new command-line options: -noshared and -encoding XXX. Also, now warning exceptions causing disconnects are reported to user, except for the case when a user has closed the viewer window. Better packaging in Win32 version: self-installing package is available, vncviewer now shows correct icon image.

Unix vncviewer: Default tunneling command template has been changed, to allow tunneled connections to hosts where only loopback VNC connections are enabled. New "-compresslevel N" option implemented in vncviewer to set compression levels for Tight encoding 1 - fast, 9 - best. Enhanced techniques to split large rectangles in Tight encoder; now it tries to find large solid-color areas and send them in separate rectangles.

Lossy JPEG compression in Tight encoding has been implemented, new "-quality N" vncviewer option should be used to enable this feature 0 - low image quality and best compression, 9 - best image quality. JPEG compression is used only for screen areas that seem to be suitable for JPEG compression although algorithms to detect such areas are not perfect, of course.

New "XCursor" and "RichCursor" encodings implemented. They are used to transmit cursor shape updates from server to clients "local cursor" feature requested by many users. Using the default configuration, i. Encoding of screen images It's a case of playing with the various algorithms that can be used for encoding screen data during transfer. There's clearly no one solution that covers every need. If there was, we would have implemented it! What we suggest is that you consult the test results page on the official TightVNC site at.

This will help you get a better understanding and appreciation of what goes on in terms of data volumes and compression times when you chose one algorithm over another. English only If you want to optimize your connection, therefore, you're going to have to try out all the different parameters and find out which combination is the best for your particular needs. The main arguments to look at are: "-encoding tight": This is the default value and the argument that gives the lowest transferred data volume.

It's what you need if you are taking control remotely via a modem or ISDN line. It will however cause a fair amount of latency due to the compression and expansion stages. It is no doubt your best bet for a local area network, whatever its configuration.

This limits the color depth to 8 bits, i. You'll lose out a little on quality, but you will win in terms of required bandwidth, hence speed. JPEG quality can be set to between 0 and 9, with 0 being "worst" and 9 being "best". The compression ratio can be set to between 1 and 9, with 1 being "mildest compression" and 9 being "strongest compression". Here are some examples: "-compresslevel 9 -quality 0" will give full-strength data compression with a more or less lousy image, but the volumes transferred will be quite trivial.

Example of some command line combinations: "-encoding tight -compresslevel 6 -quality 6": The default setting! Using in conjunction with Zebedee As is the case with all tunneling software, packets are compressed before sending them through tunnels. To perform this compression, processor resources are of course required. Moreover, TightVNC itself uses all sorts of compression algorithms to reduce the size of the images going through the "pipe" to the controlling machine.

This tool requires processor resources. But here's the rub: compressing data that's already compressed often leads to an increase in size, so you lose out twice! In particular, it includes management of transparency effects OS Vista and higher, Office menu button To copy the driver installation file on the remote host, please verify in the TightVNC remote control configuration General tab , that the box "Copy video driver DemoForge Mirage when installing the service is checked.

Then, after having launched the TightVNC control on the remote host, the driver could be automatically and silently installed, directly from the TightVNC viewer "Mirror video driver manager" button. Depending on the remote host OS, you will be probably asked to certify the program via the "publisher verification of the driver software" window. Then please click on "Install this driver software anyway".

It may be necessary to re-launch TightVNC so that the driver is supported after installation. However, be careful because known compatibility problems may arise in some configurations and OS read more.
