Just as a last ditch effort, something to try when I had a similar problem.
Most LCDs have a detachable cable. I've had the one on the back of the monitor come loose before. It didn't -look- loose, but when my LCD at work was
displaying the same behavior you describe, I reached around and re-seated it and haven't had problems since.
