I have the latest drivers of everything I have on this computer.

Other screens work fine at higher resolution, even my 12 year old novita screen can manage to squeeze out WAY higher resolutions than this syncmaster is doing right now. I have tested another T220 from a friend of mine, which also works fine.

I'm running this screen on Nvidia Geforce 9800 GTX+ in a computer with the Intel Core 2 Duo E8400, 3000mhz (9x 333)processor with 4 gigs of DDR2 Ram.
