Is 5m for DVI-HDMI alright? I have a ATI X300 with DVI, my existing DVI-HDMI cable has two sets of three pins, but I've noticed dual link has the entire set of pins. Is it ok to buy dual link, I presume the ATI doesn't support this, it should still work ok? It's a "DVI-D 18+1 Pin Male to HDMI Male"
