[mythtv-users] Xorg: TV Screen Resolution?

[Shawn Haworth]

Denis,

You'll want to setup your device and screen sections similar to this:

Section "Device"
        Identifier      "RADEON-TVOut"
        Driver  "radeon"
        Option  "AGPMode" "4"
        Option  "AGPFastWrite" "yes"
        Option  "TVOutput" "NTSC"
        Option  "IgnoreEDID" "true"
        Option "MonitorLayout" "NONE, CRT"   #here it is!
 EndSection

 Section "Monitor"
        Identifier      "TV Monitor"
        HorizSync    30.0 - 40.0
        VertRefresh  60
        Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628
 EndSection

 Section "Screen"
        Identifier      "TV Screen"
        Device          "RADEON-TVOut"
        Monitor         "TV Monitor"
        DefaultDepth    16
        SubSection "Display"
                Depth           16
                Modes           "800x600"
        EndSubSection
 EndSection


You'll need to add another monitor (your tv) with the correct vert refresh
and horiz sync.  You can find this either on the back of the television or
in the user manual.

Good luck.
