What is Hz(Hertz) in PC Monitors?
Hz represents the number of times per second your screen is refreshed. 60Hz – 60 frames / 1 second = 1 frame per 0.017 seconds 144Hz – 144 frames / 1 second = 1 frame per 0.007 seconds
What's my benefit?
144Hz display refreshes 2.5 times more frames per second than 60Hz allowing much more smooth, blur-free images in motion. It also minimizes “Input Lag” of slight delays between your actions and what is displayed on the screen. The difference is much more apparent especially in playing FPS games.
