•
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.
