Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz) For example, a TV witâ¦h a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
Your monitor or display is where refresh rates come in. Refresh rate is measured in frequency (Hz) which is the number of times per second your monitor can redraw the screen. A refresh rate of 85Hz means that your display can redraw the entire screen 85 times in one second.
