refresh rate

(hardware)
(Or "vertical refresh rate", "vertical scan rate") The maximum number of frames that can be displayed on a monitor in a second, expressed in Hertz.

The scan rate is controlled by the vertical sync signal generated by the video controller, ordering the monitor to position the electron gun at the upper left corner of the raster, ready to paint another frame. It is limited by the monitor's maximum horizontal scan rate and the resolution, since higher resolution means more scan lines. Increasing the refresh rate decreases flickering, reducing eye strain, but few people notice any change above 60-72 Hz.

refresh rate

(1) The number of times per second all the pixels on a display screen are re-energized. CRTs required constant refreshing to keep the phosphors activated even when there was no change in the image. Flat panels (LCD, OLED, plasma) have a maximum refresh rate in order to support motion in the range of 60 to 240 Hz. See pixel response time and vertical scan frequency.

(2) The number of times per second that a DRAM chip is re-energized. See dynamic RAM.
