I installed Ubuntu 12.04.1 in a desktop with the following specs:

 CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz 
 Motherboard: Intel DH67B

However the monitor is not identified (Monitor: Unknown) such that maximum resolution is 1024x768. This occurs with Samsung Syncmaster 2033 (resolution 1900x600), and is the same with ViewSonic VX2453mh-LED (resolution 1920x1080). I'd be very grateful if anyone could give me a suggestion as to how to fix the resolution.

I'm not an expert on the matter but telling users what graphics card you're using might help as it could be an issue related to your graphics card driver. – Oyibo Nov 18 '12 at 9:22
Thank you. The card driver is intel too, integrated to the motherboard intel DH67BL. – rtorres Nov 18 '12 at 11:50
