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 less latency between frames.  


For a display with 60 Hz: 1 Hz = 1000 milliseconds, 1000 milliseconds / 60 Hz = 16.67 milliseconds = the latency
For a display with 30 Hz: 1 Hz = 1000 milliseconds, 1000 milliseconds / 30 Hz = 33.33 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.

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 less latency between frames.

For a display with 30 Hz: 1 Hz = 1000 milliseconds, 1000 milliseconds / 30 Hz = 33.33 milliseconds = the latency

Latency due to limitations of refresh rate can be reduced by increasing the refresh rate. For example, a display with 60 Hz would have the latency of 16.67 ms, half of the 30 Hz display.
