When I was single and living in a 1 bedroom apartment, I had my gaming rig next to my TV in the corner. I ran a long HDMI cable along the baseboard, around the corner, and into the TV. It was clean. I had this keyboard/touchpad combo in addition to my regular mouse and keyboard and that was how I turned my dumb TV into a smart TV running Windows 8.1 circa 2013/2014. I had a DualShock 4 that I’d use specifically for couch gaming because I didn’t always want to play at my desk. My PC has a BD drive so I used it as a Blu-Ray player, too.
I was real proud of that setup. I’m married and we work from home now and so we have to have an office, but I’d love to get an Ethernet cable run between our living room and our office so I can use my laptop to stream my games and couch game again. All I have for couch gaming these days is my ancient consoles (PS2 and Wii).
