Oh, well that all still works fine then as long as you aren’t tripping over the cabling. The USB over ethernet adapter is like $50-60 in the US. A one-way long fiber optic HDMI will probably be similar in cost, and ethernet is super cheap. Way lower latency than trying to use moonlight/nvidia streaming or steamlink over wifi.

Do you own where you live? I ran a long HDMI and an ethernet through my attic from my office to my living room. The HDMI does display for my gaming rig in my office, and I have each end of the Ethernet plugged into an “AV Access” brand usb-ethernet-extender. Works perfectly to make my PC a console-like experience in the living room. Only downside is needing to go into the office to turn it on.

Mine “hangs” for a while but does EVENTUALLY boot. It takes like 3-5 minutes though which is very unusual. It used to boot in a few seconds (nvme ssd boot drive), so at first I was worried maybe the drive was going bad.
