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.
