somewhere in display settings, under monitor I think, you can uncheck a box that says "hide display settings..." or "only show settings my monitor can handle" or something like that. Check or uncheck it so that it shows all resolutions. I have yet to find anything other than allegations that a computer can't do 640x480... Installation of windows is done in 640x480 so I won't believe it til I actually have one in front of me that won't do that res. :)
