HDMI 4K Cable, 75 ft.
These High Speed Ethernet (HEC) HDMI cables support up to 4096 x 2160 resolution (roughly 4 times the resolution of 1080p) plus an additional, dedicated data channel. The data channel is known as the HDMI Ethernet Channel, for bi-directional networking at up to 100 Mb/second. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.
The HDMI Ethernet Channel was a great idea since it would allow you to use one cable for both digital video/audio and ethernet...however, looks like the manufacturers did not take advantage of the ethernet channel since you can't find equipment that actually uses the ethernet channel on the HDMI connector!
