recommended resolution.
y
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.
y
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.
