That makes this even easier because you can use an old cable to fish through a new one.
I got a 100ft iBirdie hdmi 2.1 cable running from my home office to my living room LG C1 and it only cost 70 bucks. I got full 10 bit 4k HDR and 120hz. Works like a charm. I've read reviews of people not having a great experience with this cable though so I may just have been lucky.
Thunderbolt would be better but I personally dislike thunderbolt when you need to run multiple screens. Also depending on the motherboard in question you may need a thunderbolt expansion card. Currently I run the tv, one 4k 144hz, and one 1440p 165hz monitors and it's nice to just have them all plugged in and disable the screen(s) that I'm not using. I use a Logitech wireless keyboard and track pad, xbox controller, and steelseries arctis nova pro headset to game while in the living room and it's glorious.
I also have a thunderbolt dock for my work computer at the desk to drive the two monitors. The monitors have built in kvm switch to support peripherals and a display for my home server as well.
Only reason I brought all of this up is to help people googling this issue and looking for solutions.
I'm gonna drop a dumb but effective answer:
100ft optical hdmi cable, optical USB hub.
Also there is a pcie card you can add to your PC to remote start it with a fob.
Oh absolutely. It's nice when you have a wireless setup. I myself am going to look into the wireless solutions. Keep in mind though that at a certain point bandwidth is going to limit you. I play on my TV for one reason: 4k on a big fuckin OLED screen with HDR. I want the best possible picture quality and as many frames per second that my TV will display. 1440p is an excellent compromise to achieve a higher framerate but with hardware getting better and better and DLSS/FSR really getting better, you may find yourself limited by bandwidth. I believe hdmi 2.1 is 48Gbps and I know display port is less for the same quality but still beyond the max bandwidth of most routers
