What does hertz mean on the computer screen?

Hertz is the unit of frequency in the international system of units. It is a measure of the number of repetitions of periodic changes per second. ?

Hertz is abbreviated as Hertz. Vibration (or oscillation, fluctuation) once per second is 1 Hz, which can also be written as times/second or weeks/second. Named after the German scientist Hertz; Hertz experiment proves that electromagnetic wave exists, and its propagation speed is equivalent to the speed of light. Hertz experiment has opened up an innovative road for the development of radio electronic technologies such as radio, radar and television.
