Fight online battles on 27-inch 165Hz gaming monitors. These screens offer a better overview of the playing field than a 24-inch 165Hz gaming monitor, so you can spot your opponents sooner. A 27-inch gaming monitor is about 12% larger, so open world games also come into their own better. With a 165Hz refresh rate, images move realistically fast on your monitor, and you can profit from 21 frames more than on a 144Hz gaming monitor.
