Computer Networking with TV

[Bevzy]

So I am not looking for anything about building a computer itself, I've already got that part of my setup sorted. My goal here is to have a way to use a TV in a separate room as a monitor and have a way to use all types of peripherals in that second room (ie. keyboard, mouse, headset, racing sim components). I found this video on the LTT channel which essentially does what I want but it seems like an overly expensive solution and isn't a one cable solution.

 

I'm currently planning to run an ethernet cable from my bedroom (where my computer is) to the TV room, then use a KVM extender such as the TESmart HDMI KVM Extender to send display and peripherals signals between rooms. I am also planning on adding in a HDMI splitter at my computer, so I can just switch a button to change to using the TV rather than the monitor at my computer.

 

Budget (including currency): $300-400 AUD

Country: Australia

Games, programs or workloads that it will be used for: Media playback, racing sim/general gaming

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

I'm wondering if anyone has any experience in this sort of networking, or if you had any ideas about how else I could go about doing this? The KVM Extender I linked above seems to be quite basic and wouldn't support all the peripherals I want, but I can't find anything mid-range before getting to some really expensive hardware. I would also prefer to use displayport rather than HDMI, but that is not very important. I also don't know what kind of latency I could expect when running these sorts of systems, which will be quite important for certain video games.

 

Any help would be greatly appreciated.

Thanks!
