I use a single curved 49" 3840x1080 monitor rather than 2x 27" 1080P monitors. This monitor can accept 2x 1080P inputs at the same time and run at Side by Side mode if I want to. But I find that in general, keep it a single 3840x1080 is better than 2x 1080P. Because I can treat it like 3x 4:3 monitors, and I don't have to face directly to the gap.
