I am trying to use my Sony 32" HD Ready LCD TV as a secondary (or primary) screen on my laptop, a Dell Inspiron 820 with nVidia graphics (proprietary drivers installed via openSUSE repos). I do not have any problem attaching it through VGA, the desktop displays nicely but with totally wrong resolution for the TV.
No matter what I do, I fail to configure the right resolution for the TV, which I think should be 1280 x 720. I have tried both KDE Personal Settings and nVidias “nVidia X Server Settings”. I did this yesterday, now I cannot remember if I even had the option 1280 x 720 in either of the two tools I tried, I think I did not.
Anybody got any ideas? My system is openSUSE 11.3, KDE 4.4.4, nVidia driver 260.19.29.
