12.04 - nVidia FX5200 Can't set resolution upper than 800x600

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.

Ubuntu: 12.04 Precise Pangolin

Your FX5200 is 9 years old now - see here. It's not supported by the Nvidia current driver anymore. You need the 173.x branch of the driver. (read here). Install it using the nvidia-173-updates package instead of current.
