My Samsung 213t Display periodicaly becomes corrupt. I get horizontal pinkish lines in the white ares and horizontal green lines in the darker areas. It normally happens when I scroll a window or move a window. It may run all day before it happens or it might happen when I first boot up. Sometimes I can refresh the desktop or scroll windows and it is cured or other times I have to reboot. I have a ATI 9700 pro All In Wonder video card with the latest drivers on XP SP2 all updates. The problem occured ibn safe mode while I was reinstalling my ATI drivers so I do not think it is a driver issue. Also the Samsung web site said to unplug display from pc and turn it on and if you see their logo it is a video card problem. I saw the logo. I captured a screen shot to post here . What do you guys think? Video card??
