Hi there, I recently upgraded my Windows 7 Ultimate RC to Windows 7 Ultimate full version. However, after I finished the installation, I can't get my screen resolution to go higher than 1024 x 768. However, on the RC, I had my resolution at 1280 x 800, which is what I'm used to, and I can not change my resolution back. Do I need to upgrade a driver or something? Maybe uncheck a box somewhere? I am clueless with this sort of thing, please help me out if anyone knows what to do! Thanks!
