I'm currently running Windows XP on a machine with dual monitors. Until recently, those two monitors were identical 24" Dells with native resolutions of 1920x1200. I just replaced one of the 24" monitors with a 30" Dell monitor that has a native resolution of 2560x1600. As soon as I hooked it up, I was able to set the resolution to its native res of 2560x1600. After I rebooted once, the resolution got changed by the system and highest it will go is 1920x1440, which looks horrible. My question is, why can't I set it higher to its original native resolution of 2560x1600?
A few other things worth mentioning...I'm running two dual monitor programs called DisplayFusion and MultiMon Toolbar, both of which I suspect could be messing with things. However, I've turned off both and restarted and the problem still persists.
