I have a 2007WFP that runs perfectly at 1680 x 1050 under XP SP2. However, I have installed Vista in a dual-boot format on the same PC (Dim 5150 with an ATI Radeon X1900 GT graphics card) and that particular resolution is not even an option.

 

Just yesterday I downloaded the Vista-specific drivers for both the monitor and the graphics card, and I still cannot get the option. I even uninstalled the drivers for both so that it had the native Vista drivers and it still doesn't showup (the max under all conditions is 1600 x 1200).

 

Does anyone have any ideas?
