yVertical 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.

yHorizontal 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 Hz.
