Yes, I did. I used to have 3 monitors: the laptop on the left, 27" horizontal in the center, and 27" vertical on the right side.
I switched to a single 4K 43" monitor (Dell U4320Q). I consider it the best thing I've ever bought. Paired with a window organizer (Moon) and virtual desktops, it is a very flexible setup, and also simple (no more dragging windows across monitors, no more dealing with window reshuffling when unplugging the laptop).
