Help!!! I have a Gateway flat screen monitor (about 3 years old) and yesterday the right side of the screen stopped working. The right half of the screen is pretty much white with a few very thin red and blue verticle lines every 2 inches or so. My question is, is there a way to know if the problem is the monitor or the video card? I don't have a spare monitor or PC so I can't try switching monitors or testing the "bad" monitor on a different PC. Just wondering if anyone has any suggestions before I go buy a new monitor. TIA!
