Mac's a bit differant than windows. To change your screen resolution first change the monitors refresh rate to something like 75 hertz. Than you can change the Screen resolution. Thats how it is done on a windows machine. Than again your Mac might need a video card software update.

Make sure your drivers for the video card are installed or installed correctly.
Goto your video cards website and download the latest version from there. The drivers installed by Windows are more a generic version, and extremely trimmed down.
Hope that helps

Odd problem. To solve, best bet is too reboot computer, press F2 to enter system settings. Go to visual performance and set a terminal networked computer default. May reset all other setting as well though.
