    I did a search on here and didn't find anything specifically addressing this. Here is what Monoprice says:

    Question: What is Category 2?

    Answer: Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.

    Standard (or ?category 1?) cables have been tested to perform at speeds of 75Mhz, which is the equivalent of a 1080i signal.

    High-Speed (or ?category 2?) cables have been tested to perform at speeds of 340Mhz, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).

    It is possible for a cable to pass a 1080p signal and 1.3 extended bandwidth signal without being Category 2. These cables would have bandwidth that are beyond category 1 but below category 2. Most of our non-category 2 cables perform in this range.


    Having said that, is there any reason to actually buy the category 2 instead of the category 1? I only need a 3 ft cable, and the category 2's only come in 6 ft. or 10 ft. varieties. The category 2 is only a few dollars more, but since my components are so close together on the same TV stand, I figured the 3 ft. cable would probably be best to eliminate cable/connector strain. Plus all of the "normal" colored category 2 cables are out of stock right now. I have a Sharp Aquos LC46D64U and a Toshiba HD-A3 HD-DVD player.

    Having said that, is there any reason for me to get one of the category 2 cables, or is it just a gimmick?

    Your A3 does not do 1080p, so just get cat 1. for short runs, they are not different. Just so you know, I have the same player hooked up to a Optoma HD6800 and I tried 1080o and 720p, using the cheap 15' moniprice hdmi cable this one

    and everything is fine.

    Are you talking about CL2? That is fire retardancy rating, nothing to do with the performance of the cable.

    If they are truly testing and certifying the cable, which is an excellent idea then I'd be sure to get the higher rating.

    No, it is not CL2. See the description in my OP as to what they claim is the difference between category 1 and category 2.

    Like I said, unless you are talking about in wall CL2, any cat 1 cable will work.
