http://askubuntu.com – When I install nVidia drivers from terminal with this command: sudo apt-get install nvidia-current ... and I reboot, I get the max. resolution 800x600. I added new mode successfully with xrandr, but my display is 480p. My display is connected to my PC with HDMI and in Windows I was have VGA resolution on HDMI but after I installed in Ubuntu the drivers, the resolution is 480p.How to fix that? And can I change the 420p to 720p or 1080i ? Because my display have option "HDMI Full PC mode" which is good because I can see my display fully, but the Full PC mode is not supported for 480p.
