It's a long shot, but i wondered if anyone had any idea's what could be causing this problem.

My mate owns his own shop, and for a while now when he puts his CCTV on a multiple camera view all the screens get funny coloured lines at the top of each camera image.

If he changes the view so you just see 1 camera the image is fine.

Could it be something to do with the video card, canít cope with that many images on the screen?

The box he has is a ADATA Colossus Lite

I donít have a clue what it could be, so any help is appreciated

Cheers

James.
