My experience with a 39" (1m) 4K monitor for several years now is not all joy. Part of it is that GUI elements get lost in the corners, very difficult to see, because my visual DOF is rather shallow in low light with positive diopter reading glasses, and the center of the screen is a very different distance than the corners, and the corners are oblique. The best-case use of the monitor is for viewing images from about 2 to 3 times as far from the monitor than normal viewing distance, but then GUI elements and text get unreadable, unless they are large, and use up a lot of screen real estate. So, the only way to see more GUI material on the monitor at normal viewing distance is to move my head in X/Y translation. I must look like a hawk moving its head side to side to better see prey. I wonder what a curved screen could do for this, as I've never used one.
