I have a dual monitor set-up, one runs at 1280x1024 and the other has a native resolution of 1920x1080 but gets displayed at 640x480.

Note: My friend has the exact same monitor (bought from the same store on the same day) and it works fine.


Monitor: Acer H243H
Video card : GTX 470
OS: Ubuntu 12.04

So far I have tried:
- deleting xorg.conf
- plugging in my friends monitor, saving xorg.conf (from nvidia utility) and plugging mine back in
- changing to the post-release drivers
- the above without the 2nd monitor
