A:Answer I've not mounted curved monitors, but I don't see a reason why not. The question would be about span and weight. My 27 inch monitors easily hang in the mount with ample room for wider monitors - though I can't talk about the effect of heavier monitors. The current span on my unit is 13 1/2 inches for each arm, leaving a couple inches extra width before reaching maximum (as discussed in greater detail below).
Each arm can extend 16" from the center at maximum reach. The feet form a "V" shape and extend roughly 10 1/2 inches from the center line. The arm has two sections with a joint in between (there is a third section which attaches to the monitor, but it is always perpendicular to the monitor). The section of the arm closest to the center pole spans 9 1/2 inches from the center line of the pole, and the outer section is 6 1/2 inches.
