I just received my new Dell U2412M monitor and am setting it up with my HP Pavilion laptop running Windows 7 64-bit with a Nvidia G105M graphics adapter. I downloaded the most recent driver (version 334.89) from the Nvidia website, however, I'm not able to set up the monitor with 1920x1200 resolution. It is recommending 1600x900, which is the highest option. I'm wondering if I'm doing something wrong or if my current laptop/graphics card will not support a higher resolution? Thanks for your help!
