I have a dual monitor settup, using two Dell 20" monitors, when running xp pro they can both happily run 1680x1050 on an x1950pro, but when running on vista ultimate x64 the second monitor is forced to 1377x876 (or something close) this is running with latest drivers for the gpu, and I have tried with others. But when I try to set the second monitor to run as 1680x1050, it says that it is running out of range. with 60Hz refresh rate also. Anybody know a fix?
