Claude:
Watch this video and you get the point.
http://www.cbc.ca/mrl3/8752/marketplace/packing_the_deal.wmv [it's a report by a major broadcaster in canada about the HDMI cable scams. If you have trouble opening it, let me know and I'll upload it to youtube. It basically states that, as it should be, any reasonably made cheap cable would obtain the 100% exact same end result as an expensive one]
quote: Bobby Henderson If you mistakenly buy a cable that only supports HDMI 1.1 or 1.2 features you may be limited from using newer Blu-ray oriented features like deep color, 1080p/24 frame rates and next-gen audio format support (Dolby TrueHD, DTS-HD, high bit rate LPCM).
Bobby is not entirely right as officially there is no such thing as "1.1" or "1.2" or "1.3" cable. An HDMI (certified) cable is a cable and period. But HDMI indeed establishes two cathegories, cat 1 and cat 2. This is from HDMI consortium own's website:
http://www.hdmi.org/learningcenter/faq.aspx#48
quote: 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).
But in practice, Bobby is right as a lot of (bad) manufacturers decide to label their cables 1.2, or 1.3 or whatever. If you can determine a particular cable to be cat 2 (should be officially labelled "high speed" as oppossed to "standard", may mention HDMI 1.3 in the package), fine, buy it. If not, don't worry much about it. No reason for them to cost more than $10 for a normal length good one and you can always get a new one later on if you ever need it for extra bandwidth applications in the future.

The small manufacturer pointed by Mark Ogden above (blujeanscable) seems to be fairly decent guys and, while of course trying to defend their products advantages over others, seem to make fair and balanced (well, only slightly skewed to their advantage) points in their website.
You may want to read their FAQ page, specially sections like:
http://www.bluejeanscable.com/articles/hdmi-spec-versions.htm?hdmiinfo
quote: Many people are worried, when buying HDMI cable, about the spec version of the cable in question. Is it the latest spec version? Will it support all the features of the devices it's hooked to? Most of the fears and doubts associated with this question are unfounded, but there are some interesting issues with regard to HDMI spec version, and we'll sort those out here.
http://www.bluejeanscable.com/articles/hdmi-cable-information.htm?hdmidept
quote: We're often asked whether, if one is just running a short (say, 6 foot) length of HDMI cable from one device to another, without switches, couplers, relays and whatnot, there will be any quality upgrade in sound or picture from buying a higher-quality HDMI cable, or whether one should just go with something reasonably-made and economical. The answer is that, at short lengths, in the vast majority of circumstances, all non-defective HDMI cables will perform equally well (and no, it doesn't matter what spec version it is); the signal is digital and the devices don't know whether they're hooked up with a four-dollar cable or something better or pricier.
The short-short-short "answer" is: for a short length, any reasonable, non-defective cable is good, and they can be as little as $3 and still be "perfect" and good quality.
Most cables are cat2 capable whether tested, certified, or whatnot, at those lengths. You may find some really crappy generics that are not, but that would be a matter of bad luck, as good cat2 generics abound. If you buy a non-generic or, even better, a truly brand-name certified one, then you are guaranteed "perfect" performance, no matter if the price is high or low.
Only time when cable "quality" (or rather, mostly cable gauge and shielding) come into play, like in any other digital high bandwidth application, is in long runs. Say stuff over 15 feet. Then you may want to start worrying (a bit) and look into it a bit closer. Still, no need for cables up to about 30' to be expensive at all, and certainly not above $100 for just about any reason whatsoever.
Except marketing reasons, of course. Then you can be silly enough to spend $1000 in a piece of cable and tell all your neighbours about it (altough I would be ashamed-silent rather than boasting about how stupid I was).
This place carries cheap cables convinienly:

There are many places like that. I've bought japanese media and generic asian cables from them. No complains with either (on the contrary). [ 02-14-2009, 12:29 PM: Message edited by: Julio Roberto ]
