Verticalfrequency In order to display an image, the screen must be refreshed dozens of times per second, like a fluorescent lamp. The
number of times the screen is refreshed per second is called vertical frequency, or refresh rate, and is represented by Hz.

Horizontalfrequency The time it takes to display one horizontal line is called the horizontal cycle. If 1 is divided by the horizontal interval,
the result is the number of horizontal lines displayed per second. This is called horizontal frequency and is represented by kHz.
