2 Asus 27" 1440p monitors center and right. 1 Dell 4k ultrasharp on the left and my laptop display underneath. My own PC connects to the two Asus; my work laptop connects to the Dell and center Asus and depending on if it is work time or play time, I swap the input on the center monitor. Input director provides mouse and keyboard access across both machines and works really really well. I do use all 4 monitors throughout the day; the personal machine isn't tied into work but with input director the clipboard is shared across for copying and posting information found on searches etc. I work remotely.
