I know this problem has come up before, but I need to ask...

I just bouth Vista Premium 64-bit. I'm running it on a 17" Acer flat screen monitor with an XFX GeForce 8800GT video card. I've tried changing the resolution and it will only let me go up to 1024x768. Even if I change the setting in advanced options that allows you to see the unsupported resolutions...nothing changes. 1024x768 seems to be the max It can reach.

I've read a number of forums but no one seems to give a solid, safe answer that makes sense, really. I have the latest drivers and everything.

Little help? This res. is killing me!
