My wife's grandparents have a Dell LCD monitor, sorry I don't have access to the model right now, where the entire screen is covered in horizontal waves. It looks there is a heater in front of it and you are looking at the screen through the heat waves. That's my hillbilly description of it anyway. I checked the connections and did a general scan for possible interfering energy sources. Nothing appeared unusual. There have never been any problems and no message or event preceded the malfunction. Everything looked fine in the device manager as well.
I tool my lcd monitor and connected it to the computer and it worked fine, however, upon reconnecting the old monitor the picture was fine. The picture remained fine for several hours but the waves came back. Could this be the video card, the monitor, some mysteriously disappearing driver, a virus or what? They don't want to get a new monitor and have the same problem, same with the video card. Any ideas for a more difinitive test or about what might be the problem??
Thanks!
