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.
I’m probably mistaken, but I think there might actually be a plugin for this? I haven’t looked into it myself but I swear I scrolled past a plugin listing similar functionality at some point. Or I could be hallucinating. Or it could even exist but no longer work on the current version of the app. Who knows!?
