Yeah I may end up looking into a 4k one at some point as I kinda want a 4k monitor. The issue is most KVMs are PS/2 and VGA. So hard to find USB ones. This one is USB and DVI, so it probably won't do 4k.
Though I also kind of want to just setup my gaming machine with the TV. I should just need some kind of TV stand to play off of, and I'm not sure how well gaming would really work on the TV. I think I have to try it for a bit and see how it goes. I can probably also use that machine for movies, youtube etc... so much easier than fiddling with a remote with Kodi and not knowing which button to press to get certain menus etc. I find it can be awkward to use. That and Kodi puts subtitles by default which is freaking annoying.
