Problem with the U2415 is it doesn't have the amazingly low total latency that the U2414H has. Including the latency from the panel itself, it is about 4ms from pixels flowing into the monitor to them flowing out to your eyeballs: this is better than every single gamer-oriented monitor on the market (which virtually all of them buffer 1 frame, which at 60hz, is 16.6ms, plus another 2-4ms from the panel itself).
