Changing monitor resolution on 12.04

[Jim Byrnes]

On a fresh install of 12.04 how can I change the resolution of a 
Hannspree HF235.

I was able to set this monitor to 1920x1080 on 10.04 but the best I can 
do on 12.04 is 1024x768.

Video is an onboard gforce 9100 and I am using the first selection 
presented in the install additional drivers gui interface.  The driver 
is Nvidia vers 295.40.

This is the same setup I was discussing in a thread about Twinview, but 
I started a new thread because the problem is not with Twinview but is a 
problem with this monitor.

Thanks,  Jim
