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.
