Could I use 1/4 of a 4K TV as a monitor? I mean.. Obviously the desktop would cover the entire screen but what I want is to be able to do 1080p gaming on 1/4 the screen while someone else watching a movie on another 1/4 of the screen. Also.. Would sitting close e to the 4k TV as if it's a monitor be ok? 4k is 4x 1080p right? Also.. Would 1/4 a 4k monitor do gaming look the same as my 1080p monitor in quality?
