I have a Sammy HLN507W DLP and I want to hook a computer up to it for some light gaming and surfing. The DVI input is already being used by my Sammy HDTV Directv reciever. I have tried the computer with S-Video (Geforce 2 card has s-video) and the picture is terrible. I am wondering if the VGA input would be better and if so what cable do I need. I have seen it referenced as a VGA cable and a D-sub cable. Can someone tell me if the picture will be better and what cable I need....maybe a link to one???? Thnks.
