I've uninstalled and reinstalled the NVidia drivers and the problem persists. The highest I can set the resolution and not get a "scrolling" desktop is 1024x768.
What happened and how do I fix it? It had been running at 1680x1050.
Monitor: Acer AL2216W
Videocard: XFX Nvidia GeForce GTX 460 SE 1GB
Driver: 310.70 (released 12/17 I think)
Windows XP Service Pack 3
Intel Core 2 Duo @ 2.66GHz
3.25 GB of RAM
I also tried installing drivers for the Acer, but that did not help either.
