How to Calibrate TV under Linux (NVIDIA)

VertX · 02-07-2008, 03:12 PM

Hi
I installed latest NVIDIA drivers from official site, connected TV through composite. I Set two separate X screen. My LCD to 1280x1024 & Tv to 1024x768 from nvidia-settings.

Everything is ok, the picture on TV goes little out of borders from all sides, that is why I can't see gnome menu on top and taskbar on bottom.
How to calibrate my TV under linux (My TV doesn't support it)

My xorg.conf is:

Code:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildmeister@builder26)  Fri Jan 11 14:27:25 PST 2008

I would guess this is a CRT TV with overscan areas. In this case, there is really no way to have it so that parts won't get cut off. The NVidia utility might work for you, though apparently not in all cases: http://www.nvnews.net/vbulletin/showthread.php?t=104769
