I recently bought a Viewsonic VA800 at a high school fundraiser. The seller swore that it worked. When I plug it in to my computer, the picture goes crazy from the start. The screen resembles an old scrambled cable channel. The menu from the monitor is fine until the desktop loads, so I suspect it is some sort of compatibility issue. The display adapter is a built-in NVIDIA GeForce 6150 LE. My old monitor is a NEC MultiSync E500.
