In reference to terminology originating with cathode-ray tubes (CRTs), the refresh rate, also known as vertical refresh rate, vertical scan rate or vertical frequency, is the number of times per second that a raster-based display device displays a new image. This can be independent from frame rate, which describes how many images are stored or generated every second by the device driving the display.
