I learned recently that most HDMI cables support ethernet capability, and from what I gather their typical usage is specially adapted for home theatre setups, and usually not used at all.
I will be threading an HDMI cable through a wall soon, and I want to minimize the number of cables going through a small hole if at all possible. One end of the cable will go to my PC (steam setup), the other end will be cut, then reassembled onto a breakout adapter, then to a TV.
I would also like to connect ethernet from my TV to a network switch (not my PC). So to save on cables I would ideally like a pair of devices: One takes ethernet from the switch and HDMI from my PC and outputs HDMI w/ Ethernet. The other takes HDMI w/ Ethernet and outputs HDMI and an ethernet plug.
Does such a pair of devices exist? I tried looking online and all I can find is the exact opposite, devices that mangle HDMI into a pair of dedicated ethernet cables and back.
