I am about to move into my new appartment and I have to following problem: I will have my desktop pc in my office room and would like to connect my 4k TV (LG, 2018 model) to my pc for some gaming on the couch (4k appreciated, 1440p and 60 FPS required).
However, I do not know what the best (and reasonably cheap) solution would be. I do have an existing connection via Ethernet cable and also have the possiblity to get another wire through the existing cable tubes in the wall. The range would be approximatly 20 meters, coming through a electrical box after approximatly 5-7 meters.
I would need both a solution for video/audio, with hdmi on the tv side, pc is either HDMI2.0b or DP1.4 (got an RTX 2080), but also how I would have to handle my input (XBox controller, both classic wired and/or Elite 2, and a wireless keyboard with touchpad (usb dongle))
Thank you for your help.
