Currently I have two PC's running in my home which is Cat 10 cabled throughout. My original build has a Dell 24" flatscreen with 1220x1200 resolution, and though a couple of years old, is still going strong.
My new PC powers a BenQ 32" 4K (3840x2160) resolution screen, which gives me a beautiful screen. My next purchase, as soon as it can be afforded, will be a VR headset. Just waiting for the right one for me, to make itself available!
