You can see from this extensive testing that ALL companies HDMI cables passed all the speed tests at 20ft or less cable distance.
ALL companies failed 1080p tests at longer cable distances for theoretical bandwidth, but when hooked up to displays Clint and the gang had to run 65 feet lines before they got ANY distortion on a Blu-ray picture.

We took two of the worst performing cables of the bunch, a RAM Electronics 50' HDMI cable ($130) and an equally challenged Tributaries (Series 9) 15 meter cable ($899). Both understandably fail eye pattern tests at even 720p resolutions. Both, unfortunately, also claim HDMI 1.3 support at up to 10.2 Gbps bandwidth and with Deep Color support. It was fairly obvious that both of these cables would fail real-world tests when connected to a 1080p source.
Except that they didn't.
I saw clean video on two separate displays. I even used two different sources - one HDMI 1.3 and the other sporting an older HDMI 1.2 chipset. Then I got real desperate and nabbed an old HDMI 1.0 source (A Helios NeuNeo player) and slapped it up to triple check the signal.
What?!? Scratching my head I searched in vain for a way to get them to fail. I couldn't. Not at 1080p or any other resolution. Finally I actually resorted to connecting the two huge cables end-to-end. That netted me sparkles at 720p/1080i and absolutely no picture at 1080p with our HDMI 1.0 player. OK, so there are some limits after all. That's good to know.
When I finally got a result, sparkles abounded on the screen, even shooting horizontal lines across parts of the picture in frequent intervals. But this was only after traversing over 65 feet of HDMI cable. So far, my theory on longer-run HDMI cables was a near-bust.

For most people without in-wall wiring, exceeding runs of 20ft are not commonplace, so why you'd want to pay anything more than the cheapest price for cables that all test the same at 10 meters or less unless you're ridiculously well off is beyond me. I mean, sure I'd spend $7,000 on Nordost Blue Heaven speaker wires if I had 20 mill in the bank, you know?
