While I typically write simply for the technophobe, a recent post by Harryitguy, made me feel like I had a couple of things to say about HDMI. Harry and many of his commenters believe that there is no difference between cables when it comes to an HDMI cable. They claim that digital signals arrive at the TV just as they were sent from the source. And there are many complaints about high priced cables. I wanted to be sure that the facts were out there.

Recently I have done in depth research with HDMI, LLC (the HDMI licensing company) and a number of cable manufacturers for my column in Dealerscope magazine to come out in March.

Here are some facts about HDMI cables:
1. Digital may be digital, but 1s and 0s can be corrupted into bit errors
and
2. Bit errors cause video noise or other picture degradation
3. Bad Cable construction can make that video noise worse when the connectors have cheap solder points or weak solder points
4. Monster cable has a one piece connector that eliminates the bit error problems. Terk makes cables that have “noise traps” like you find on your digital camera cable, to capture any added interferance. And of course, any decent cable doesn’t want interferance to cause bit errors.
5. Really cheap cables can fall out of the connection, or bend pins.
6. Alterations in what material the cable is, and how it is twisted can affect the ability of the cable to transmit the highest quality picture.

Bottom line is, if you are spending a lot of money on a high quality flatscreen or any other high quality component, why would you skimp on cables to insure that quality is transferred and displayed?
