Basically what you are looking for is a 4K TV/monitor that supports split screens with multiple inputs. I know some older TVs do that but only for 2 HDMI inputs with side by side split screens. I don't remember ever seeing one that does 4 inputs and with 4 different screens. I think you are better off just getting 4 monitors with desk arms mount. I would just the 3 monitors with arms (those are more common and fit most desks. 2 for work, and 1 for home. And you can get a switch box, so for the weekends, you can do 3 monitors gaming LOL!
