Refresh rate is the number of times per second the display grabs a new image from the GPU. It also decides the length of latency between each image. Higher refresh rate means higher potential Frame rate and less latency between frames.
For a display with 60 Hz: 1 Hz = 1000 milliseconds, 1000 milliseconds / 60 Hz = 16.67 milliseconds = the latency
Latency due to limitations of refresh rate can be reduced by increasing the refresh rate. For example a display with 120 Hz would have the latency of 8.33 ms, half of the 60 Hz display.
