I have four 4K screens, and it is heaven. I got spoiled early in my career by a Unix system that had a greyscale newspaper layout monitor in the early 90's. That monitor could crispy display an unfolded two page newspaper layout with space on the left and right for tool/editing interfaces. For a while, 4K monitors were landing right near US $300, so I got 4 over a period of months. Simply being able to array references around my work, with space to spare for communication and music interfaces. It is lovely to hit stride and before I know it the day is over, and a ton of work accomplished.
