Thanks for the reply. I don't think that a game gets it's resolutions from Windows. The video card determines what settings are available, but games must support a particular resolution for it to be used. I point to Diablo II which only offers 600 x 400 and 800 x 600. What I've learned from other posts is that Quake III and it's offspring support widescreen resolution. There's also talk of Unreal II doing so as well.
