With a 27-inch 144Hz monitor, you can game with smooth images on a large screen. The 27-inch screen has a diameter of 69 centimeters. The screen is considerably larger than that of a 24-inch monitor. Because the screen refreshes 144 times per minute, the image looks smooth while gaming. This is especially nice with fast games such as shooters, RTS games, and racing games. Combine this with 1ms if you don't want to be bothered by blurry images. In addition, G-sync and FreeSync prevent annoying artifacts during gaming, such as screen tearing and stuck images. Note: most video cards support up to Full HD 144Hz and very powerful video cards support QHD 144Hz. No video card supports 4K 144Hz.
