I have a viewsonic 19 inch LCD when ever i play dvd or tv in full screen the image distorts, the image breaks up with lines going through it. Any ideas

Hmmmm.....sounds like it could have something to do with the video card...

Can you try another monitor?

it works fine on my crt monitor

Are you running the panel at its true resolution...adjusting the video properties to match?

Have you checked Viewsonic's web site for troubleshooting information?
