I am running into an issue with 14.04. I have two monitors. the fist one is a 19 inch LG that runs off DVI at 1440x900. It seems to function just fine. The second is a 23 inch LG that should run at 1920x1200. It has been plugged in with both a HDMI to HDMI cable and a DVI to HDMI cable. It seems to be stuck in "I am displaying for a DVD player in 1080p mode" or some such. I had this issue with windows a long long time ago and eventually it just went away. I can set the screen display to 1920x1200 with the generic X drivers but I am a gamer and would like to use the Nvidia drivers since they deliver better performance. When I switch to the Nvidia driver I can set the resolution to 1920x1200 but the screen seems to be up and to the left with a black border down and to the right. If I switch back to the default X driver after this the screen remains stuck in the up and to the left mode. Any help would be wonderful.
