CD: What should consumers know about HDMI cables?
SV: To consumers, perhaps the most tangible move from an analog connection to a digital one is the physical cable itself. After all, the complicated technology that is happening inside the DVD or HDTV is invisible to all but the engineers who design these systems. So what is there to know about an HDMI cable that is any different from what we know about analog cables? Lots!
The tolerances for HDMI cables are incredibly tight. Because a digital signal is comprised of 1s and 0s, sent over four channels with 19 pins inside the cable, and because these 1s and 0s need to start and end at the exact same time, the manufacturing tolerances for cables are very high. It's for that reason that cables must be tested at an HDMI Authorized Testing Center before they can be marked with the HDMI logo. It also why it is impractical (if not impossible) to splice and crimp an HDMI cable at home (you would need to cut each strand within 1/20,000th of an inch to ensure that it would work).
Fatter cables do not necessarily mean better signals. Previously, fat cables were deemed superior because the copper was thicker and the cables carried more shielding. Additional shielding reduced the likelihood of interference between the copper strands, which led to a better signal.
In the world of digital cables, there's no need for shielding since there is no possibility of interference within a cable. As for the thickness of copper, however, thicker copper will be able to extend the length of a digital signal, but for shorter cable lengths (two meters and under), there is no need for overly thick copper strands. In fact, thicker cables can sometimes be problematic since they are less flexible to bend around sharp corners and the increased weight can cause them to fall out of vertically mounted connectors.
Perhaps the most confusing aspect of an HDMI cable is cable length - how long can an HDMI cable go? You need to be careful when looking at cables that run 5 meters or longer. At these lengths, the manufacturing quality of cables has everything to do with whether or not they will work at longer lengths. For very long cabling needs, there are cable extender products that effectively boost the signal and extend the effective cable length. In addition, some HDTVs are designed with HDMI electronics that have greater sensitivity and active equalizer technology to accommodate longer cable lengths. In all cases, make sure you look at products that have the HDMI logo on them. This ensures that the product has been tested at one of the HDMI Authorized Testing Centers and meets the HDMI specification.
