I have a Xerox XM3-19W which I have connected to an ATI Radeon 9600 card on a mobo with 648 chipset. I’m running XP SP2. I had the monitor running fine but a few weeks ago the 1440x900 resolution disappeared from my resolution options. I don’t know what caused it. I have tried reinstalling every driver imaginable (from the monitor driver to the AGP driver) but nothing will bring it back. I have even created my own driver using powerstrip but it still doesn't want to know. Perhaps someone knows about this problem or has a solution.
