In mating this wide LCD monitor to this 4-y-o computer, I have been unable to get rid of the horizontally expanded (distorted) screen. From reading other posts, it's not clear to me what I should do to resolve this, but I suspect it's a video card problem. If so, what source is recommended for an update, and am I going to see where to put it when I open up my tower? Card price? Is there a cheaper fix?
