Can anyone explain what the difference is between a single link and a dual link DVI cable? I know that they both have the same basic connector, but the dual link has all 24 pins in the connector and the single link has 6 pins missing in the center which results in 18 pins. What does single link mean? What does dual link mean? The DVI output on an 811 receiver requires a DVI-D cable, but it is not specific about whether it should be single or dual link. Will either one work?
