    Hello,

    I am in the market of a DVI-D cable to connect my Comcast HDTV box to my TV. What is the difference between the single link and dual link cable? Is there any difference in picture quality for HDTV of using one or the other? Thank you for any info.

    Andrew.

    The short answer is that you do not need a dual link cable. There is almost no equipment out there that takes advantage of the second link. Single link cables have more than enough bandwidth to support HD signals, so they are fine for our purposes as HT enthusiasts.

    A dual link cable provides extra bandwidth, but that extra bandwidth does not result in any improvement if you already have enough.
