That might partially explain the problem I have, but I am only running at 1280 x 1024 on my 19" Iiyama. When i try and switch between browsers that screen goes black and has to "redraw" the screen. I am also getting red dots appear all over the place. But I haven't yet eliminated the card as a possibility.
