Ok, so after installing Windows Vista Ultimate, and installing the ATI video drivers that came with my X1600 I was able to set the resolution to 1680 x 1050 on a 22" LCD. The only problem was that I couldn't use aero, and everytime I shutdown I would get the blue screen of death saying that there was a problem with an ATI driver: ati2dvag.dll. So I upgrade the driver to the latest on released by ATI and no longer get the bsod, but now I can't set the resolution to 1680 x 1050. I've tried uninstalling all the ati drivers and ccc, and restarting and reinstalling but nothing.
Here's my computer guts:
Windows Vista Ultimate 32-Bit
Intel Pentium CPU 3.20GHz
4.00 GB
ATI X1600 512mb
