I want to get a 19+ inch widescreen LCD (probably go with a 20 or 22 inch) and have a pretty high screen resolution. A friend hooked up a widescreen to his comp and everything is stretched out. He said he was told he needs a new video card or adapter to accomadate this. What should I look for in a video card? I don't need the best but something that makes DVDs look nice and such.
