For example, in the game, the screen content will be much wider than the traditional 16:9 display, which can better find the enemy and observe the surroundings. In addition, the g-sync technology of 40A2 and the game auxiliary collimation make the overall picture of the game more smooth, and the aiming and shooting more convenient and accurate.
