We bought a TV a while ago with the thought that one day we could hook the computer up to it. Well, that day has come, but I had trouble getting it to display correctly.
I enabled the restricted drivers for the nvidia video card. I could run nvidia-settings to configure the displays.
I had to add some options to me screen section in the xorg.conf to make it look like this:
Section “Screen”
Identifier “Screen0”
Device “Device0”
Monitor “Monitor0”
DefaultDepth 24
Option “TwinView”
Option “NoTwinViewXineramInfo” “1”
Option “metamodes” “1024x768_85,NULL”
Option “TwinViewOrientation” “RightOf”
Option “ModeValidation” “AllowNon60HzDFPModes,NoEdidModes,NoEdidDFPMaxSizeCheck,NoVertRefreshCheck,NoHorizSyncCheck,NoMaxSizeCheck,NoDFPNativeResolutionCheck”
Option “UseEDID” “FALSE”
SubSection “Display”
Depth 24
EndSubSection
EndSection
Then, I found a nice tool to generate mode lines. I put the modeline in the monitor section:
Section “Monitor”
# HorizSync source: builtin, VertRefresh source: builtin
Identifier “Monitor0”
VendorName “Unknown”
ModelName “CRT-0”
HorizSync 28.0 – 55.0
VertRefresh 43.0 – 72.0
Option “DPMS”
ModeLine “1024x768_85” 69.54 1024 1056 1320 1352 576 586 594 605
EndSection
