Rwestly , I think we briefly talked about HDMI cable length several pages back in this thread and you mentioned the short lengths giving problems . I can't remember if you were speaking from personal experience or relating information you've read . If you can remember where you read that , I'd be interested in seeing the info , not that I would fully understand the technical reasons , but I like pretty pictures . Really , sometimes I just like to geek out a bit to learn more than I need to , I tried briefly looking on HDMI.org , but the only cable length info I found (so far) discusses the general maximum length that's been certified
Q. Does HDMI accommodate long cable lengths?
Yes. HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. We have seen cables pass "Standard Cable" HDMI compliance testing at lengths of up to a maximum of 10 meters without the use of a repeater. It is not only the cable that factors into how long a cable can successfully carry an HDMI signal, the receiver chip inside the TV or projector also plays a major factor. Receiver chips that include a feature called "cable equalization" are able to compensate for weaker signals thereby extending the potential length of any cable that is used with that device.
With any long run of an HDMI cable, quality manufactured cables can play a significant role in successfully running HDMI over such longer distances.

Q. How do I run HDMI cables longer than 10 meters?
There are many HDMI Adopters working on HDMI solutions that extend a cable’s effective distance from the typical 10 meter range to much longer lengths. These companies manufacture a variety of solutions that include active cables (active electronics built into cables that boost and extend the cable’s signal), repeaters, amplifiers as well as CAT5/6 and fiber solutions
Any better refwerence sources will be appreciated , I want things as trouble free as possible in my setup , if that means switching my shorter cables for six footers , I'll do it , just want some science to back up the information . I do have some occasional signal issues , I'm pretty sure it's caused by my A/V receiver , but if the shorter HDMI might be causing the problems , I'll switch them. Thanks
