Got a Leadtek GF4 Ti4200 I was planning on using in an older shuttle with media portal hooked up to the TV via VGA. It works however the VGA and to a lesser extent DVI seem to have 'noise' on the display. I've cleaned the connections, replaced the VGA lead and had a go with two DVI>VGA dongels but it's still noticable. If I drop a 9800 or 6800 or plug the laptop in then it's perfect as is the onboard VGA. Any ideas ?
