We support a user with poor eyesight. He uses "Change the size of all items" set to "Large - 150%" to get larger icons and text.
He has the following script to allow him to request remote support:
set VNC="%ProgramFiles%\TightVNC\tvnserver.exe"
%VNC% -reinstall
%VNC% -start
%VNC% -controlservice -connect support.host.
echo Press return to end support session
pause
%VNC% -stop
%VNC% -remove
And on support.host we use "vncviewer -listen".
The problem is that using more than 125% the remote window only shows a fraction of the real screen size.
remote only fraction of original
I get the same issue. In my case, it's a home PC running Windows 8 that I use as a media centre. The system runs in 1920x1080. There are two users accounts on it. One, the "TV" account, automatically logs in on startup, and is configured with high-DPI to make it easier to use from across the room with a remote. The other account is for admin purposes, and has standard DPI settings.
If I VNC into the machine while the TV account is in use, the VNC display is only 1280x720 and only shows the top-left of the screen. The mouse position is scaled however, so that clicking in the bottom-right of the VNC viewer window triggers a click in the bottom right of the real screen, where I cannot see what I'm doing.
If I connect while the standard account is logged in, everything works as expected.
I have a setup like paul_milliken's and am running into the same problem. This bug makes the TightVNC Server application unusable while the DPI is set to 150%.
I'm also using TightVNC with DPI settings increased. This has been a problem in version 2.5 and above. This is a problem with the screen images displayed by the viewer. Moving the mouse around the screen, the cursor moves in scale with the full screen rather than the cropped desktop image.
I have exactly the same situation as Paul Milliken -- HTPC with the DPI set to 150%. With version 2.6.4, TightVNC is unusable because the scaling is wrong. This did not happen when I was using version 2.0.4.
Workaround: Use TightVNC in Application mode, not Service mode. Not so convenient, but the scaling is correct.
Thank you for reporting this bug. I had no idea why vnc was cutting off part of the screen. The solution to use server in application mode is a fitting workaround for me. I disabled the service and put the application in the 'startup' folder.
Thanks!
UPDATE: I just installed Windows 8 and the workaround is not effective. Running the server in either mode results in the screen being cut off/not scaling correctly. Boo!
We know about the issue and it will be corrected in future versions of the product (2.7 or later).
The status for this issue has been "open-accepted" since 2013, are there any plans to fix this in the coming TightVNC releases? Can you please update me? We are using the latest version of TightVNC and are facing this issue regularly in case of windows DPI changes on a multi-monitor setup in EXTEND mode, any of the workarounds listed, are not seeming to work for us.
