As you would understand from the name that refresh rate is the time taken by the screen to refresh it's displayed picture. This is measured in hertz (Hz) and the standard one to consider would be 60Hz. Which means the refresh rate is at 60 times per second. Which can be used for gaming but the higher the better so that you do not miss on any action and have no blur-outs. For this case try getting a laptop device with around 120Hz refresh rates.
