[mythtv-users] DVI Output to HDTV

I connect to my 720p native projecter via DVI.  

For me, the best solution was to remove all ModeLine's from xorg.conf, make 
sure my card's EDID functionality was enabled, and specify 1280x720 in the 
Modes section.  This allowed Xorg to dynamically access all available modes 
my monitor could handle, and choose the correct one.  

Hopefully this works for you as well.  Here is a few snippets from my 

Section "Monitor"
    Identifier  "BenQ PE8700+"
    HorizSync   20-88
    VertRefresh 20-100

    Option      "dpms"


Section "Device"
    Identifier  "NVidia Binary 1"
    Driver      "nvidia"
    Option "NoLogo" "TRUE"
    Option "RenderAccel" "TRUE"
    Option "UseEDID" "TRUE"
    Option "DPI" "100 x 100"
    Option "UseEdidDpi" "FALSE"


Section "Screen"
    Identifier  "Projector"
    Device      "NVidia Binary 1"
    Monitor     "BenQ PE8700+"

    DefaultDepth    24

    SubSection "Display"
        Depth       24
        Modes       "1280x720"
        ViewPort    0 0
