I need a DVI cable, to connect my HCPC to my Infocus 5700 projector. I THINK I need a DVI-D(not I?) cable and an adapter for the 5700 input. Since the cable is almost 10m long, I will need a good quality one. I´ve been told Lindy and Bettercables are good. Does anyone know of retailers I could order from the web in the UK?
