of the horizontal or vertical frequency range of the monitor. Please see
the Product Specification section of this manual to set the appropri-
ate frequency.

y
Use a screen saver to protect the screen when using the monitor for a
prolonged period of time.
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.
The number of horizontal lines displayed in one second can be calculated by dividing one by the
horizontal cycle. This is called horizontal frequency and is represented by kHz.
