Since installing windows xp media center edition 2005, my graphics card won't allow me to use the widescreen resolution that my display has. The maximum resolution that it says is being reported from my monitor is 1024X768. Wen i use the old driver, it will go to my native res of 1280X800, but it is very laggish and the media center says it's not copmpatible. I have tryed everything i can htink of. Anyone have any suiggestions?
