HDMI 1.4 Potential Cable Problems

Transparent Audio’s Josh Clark says, “”We are even more concerned that running an Ethernet signal side-by-side with the primary HDMI audio and video signals may actually degrade the resulting picture and sound quality because of signal crosstalk. For these reasons, Transparent is not planning to build HDMI 1.4 cables with the additional signal conductors necessary for Ethernet and Audio Return.”

Josh also said, “Consumers will have to buy all new HDMI 1.4 cables and components just to get Ethernet and audio return connectivity through their HDMI cables when they already can get these functions with existing Ethernet and audio cables.”

It does sound like many of the existing cables will support the higher data rates, but the additional audio and Ethernet capabilities will require new cables. Complete HDMI 1.4 support in a system will require new devices as well.
