Anythings possible. Could be the video card. Have you tried calibrating it? Does that make a diff? Hook the new monitor up to another PC, do you get the same problem?

Is there anything in the environment that could be affecting it? IE: monitor is close to in wall electrical wiring, cord from other "dirty" signal stuff running near monitor cables? Believe it or not cell phones can affect them. I leave my cell in front of both computers in the office, no issues. The guy in the office next to mine, his Dell 19" LCD goes weird everytime my cell rings. He knows before I do that I'm getting a call.

As you know I don't keep up on viruses much but a bunch of years ago there used to be this stupid "practical joke" utility.

You'd stick it on someones computer and every time they rebooted it would shrink the display size by 1 pixel on all 4 sides.
