Horizontal scan rate allowed by the standard was chosen to allow practical TV receiver designs. Compare vertical scan rate (refresh rate), which indicates how often the electron beam is moved from the bottom of the display to the top. Given the horizontal scan rate, the refresh rate can be approximated by dividing the horizontal scan rate by the number of horizontal lines multiplied by 1.05 (since about 5% of the time it takes to scan the screen is spent moving the electron beam back to the top). For instance, a monitor with a horizontal scanning frequency of 96 kHz at a resolution of
