Scan rate
The pace of how fast a display is redrawn. The higher the scan rate the more steady an image will appear, commonly if a display has a low scan rate the display may appear to flicker. The scan rate is commonly displayed in kHz or Hz and generally has a vertical and horizontal value. For example, "Horizontal scan rate: 30-81 KHz -- Vertical scan rate: 56-85 Hz" is an example of how a scan rate may be displayed on a monitor.
