Every second HDMI cable in store is being advertised with "High Speed Ethernet Support" on its packaging.

... and yet I have never-ever seen a single device that makes use of that feature. Have you?


It's for transferring data and to make devices communicate. E.g. the Apple TV can turn on and off the TV when activated or put to sleep. Without the TV needing to be toggled by the remote control.

@tobi Not quite, that's called HDMI CEC (pin 13 on the cable).

Ethernet over HDMI (pin 14) is an alternative way to hook up your devices to your LAN... that is if any devices out there would support that feature.
