Some (many?) HDMI cables can also carry Ethernet over HDMI. The main use seems to be to provide internet connection to a smart TV from a cable modem box. Currently I have an ethernet-USB adaptor ...
Is there any reason I can’t run USB-C cables in a wall with an adapter on the end for HDMI on the TV side? I’m building a small office/gym building. It’s that time where i need to run some cables.
