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.
However, with most TV companies switching over to 120Hz refresh rate, this motion blur has more or less been controlled. Clear Motion Rate (CMR). CMR or Clear Motion Rate is a new concept introduced by Samsung that measures the capacity of an LCD to display fast moving objects smoothly.Clear Motion 120â³ means itâs 60hz. Otherwise, they would call it âClear Motion 120hzâ. Samsung is multiplying the true refresh rate by other non-refresh rate factors, for example the number of processors or the LED backlight.
