Dell LCD Monitor Has Horizontal Lines on all Resolutions but 1280x1024

Hello!

I have a Dell Monitor model # 1908fwpt and we have used it as an external for a few laptops now, and on the last two hook-ups it has constant, non-flickering white horizontal lines across the screen. The only resolution that doesn't is 1280x1024 for some reason. I have changed the cables, used both VGA and DVI, and run the self-diagnostics and updated all drivers. I have chased this issue up and down and not been able to come up with a way to fix it. The monitor is not old, it hasn't been used very much, and I really don't want to replace it...

Any thoughts? Since its done it on a few different computers I tend to think its not a driver issue, or a cable issue... And the one resolution it works on is all stretched out and flat.

Thanks!

I'd recommend posting on the Dell forums. If it's doing it on multiple computers, it's a monitor problem.
