I have an older dell laptop that has suddenly gone from displaying the full resolution to showing the screen twice, almost like in widescreen mode, one on top of each other. They are very fuzzy, yet I can kind of still see what is going on as I navigate through Windows.
I've tried installing the latest video drivers, but the dell site doesn't have any for Windows 7 (even though it was working fine when I first got it). I assume it's a hardware thing but I hope I can be proven wrong.
