Home pc access over KVM cat7 extender

I’m looking to migrate my PC into a server rack in my cellar, but I’m unsure if my approach would work. Input would be greatly appreciated! Locale is Europe.

I’ll try to keep it short. My ventilated cellar’s stairs join my office, and I want to put my pc and server in a rack downstairs, and run a KVM swith over ethernet and HDMI 2.1 cable upstairs, where the KVM receiver will connect to a 2k 144hz display, a DAC over optical, keyboard and mouse, and the HDMI 2.1 will connect only the gaming rig directly to a 4k 144hz display. That way, I only have to hide two cables coming from downstairs, I get 4k 144hz support and I can swith between my two pc’s on the second display.

The KVM switch / extender over cat 7 I had in mind is the Techly IDATA HDMI-KVM67. It states compatibility with 4k 60hz, but would it support 2k 144hz or would I have to play with chroma subsampling?

The HDMI 2.1 cable would be an active cable of 20m over fibre.

Another question, my “server” is a ryzen system with a 2700x and a nvidia T400 gpu. It has a collection of movies on it, how would I go about getting acces to them on my TV? Get a thinclient and remote into the server? Building an old pc and accessing a shared folder? It would have to happen over wifi though. And when remoting into the server, would the server’s gpu matter? Or more so of the client. TV is regular 4k 120hz

If there is a cheaper option I’m not seeing please let me know, as of now the KVM, hmdi and cat7 cable would set me back about 450 eur

Thank you

Your situation sounds like one of those “buy it and see if it works” scenarios.

This cable should be ok but if you can go active display port it may be better. My runs are only 10m and I found the display port had fewer issues (Samsung g9 panel at 120hz)

The biggest issue is if you need usb3 at the desk. Not found a good way to do that with switching. I ended up running multiple usb3 cables and it is unsightly.

The usb over IP solutions were generally unreliable.

Raspberry pi I to your TV with Kodi or Plex is the usual way. Stream over the WiFi or wired. If you can run a cable the run another active optical cable.

If you are ok with 1080p then hdmi over cat6 extenders are fairly cheap.

Good luck!
