That would avoid any streaming latency or other bugginess, resolution, VRR, Hz, HDR limitations etc. Then you'd have a fiber HDMI output (and usb-c output) from what is typically the strongest GPU in your house at your main PC straight to your tv as if it was a monitor at your desk.

The best scenario here in my opinion is if you have a hdmi 2.1 tv capable of 120hz VRR (variable refresh rate).

They do sell fiber HDMI up to 100' or more but you are pushing your luck going that far for 4k 120hz 444 (and VRR). That and/or through a wall then using some plastic conduit they make for computer stuff (snap on little flat rectangular box kind that forms a slim box conduit strip as you snap pieces together) if you want to clean up wherever the cable is running in sight. If room(s) away this might mean running through floor joists in basement or ceiling joists in attic. They also sell fiber USB-C cables that you can connect to a usb hub at your tv for wireless devices/bluetooth transcievers. There are fiber HDMI 2.1 cables available now (8k 60hz/4k 120hz) so if you are anywhere 50 to 75 feet away you can run a fiber HDMI cable from your PC.
