What Is The Refresh Rate Of The Display Screen？

The refresh rate of a monitor is divided into vertical refresh rate and horizontal refresh rate. The unit of vertical scanning frequency is MHz, which is determined by the horizontal refresh rate and screen resolution. The vertical refresh rate represents the number of times the screen image is redrawn per second, which is the number of times the screen is refreshed per second. The horizontal refresh rate is called the line frequency, which refers to the number of times the display scans the horizontal line per second, in kHz.
