My PC (VGA Nvidia GTX275) is connected directly to a TV (Philips 42" lcd) and Ubuntu does not recognize the native resolution, the closest working resolution is 1280x768 I have tried some xorg tricks found on Google but have had no luck

Any idea how to set the native resolution?

I think the user has model 42PF5421 (check out the leaflet for more info) -- xrandr output -- the resolution 1366x768 is not supported according to the manual, but the user mentioned that it works in Windows XP (if it's the same user as the one from ubuntu-gr). Looks like a linux nvidia driver issue. –  medigeek May 9 '12 at 7:29

Eventhough I am a noob at ubuntu (only 4 days into it), i was faced with a similar delima when i hooked up my pc to a Philips 42" LCD (model 42PFL5704D/F7). You can have it set up at at that resolution (i have mine at 1920 x 1080 - and it's great. To do that you need to install the proprietary drivers from Nvidia. Simply open the terminal and enter the following commands, one line at a time:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

The reason being that the latest drivers has not yet made it to Ubuntu's repositories.

Hope this helps.

Note 1: I think the resolution you were going for is 1360x768. Note 2: Make sure your tv is setup to unscaled (Menu > TV Settings > Picture > Unscaled).
