Dot Pitch

The image on a monitor is composed of red, green and blue dots. The closer the dots, the higher the
resolution. The distance between two dots of the same color is called the 'Dot Pitch'. Unit: mm

Vertical Frequency
The screen must be redrawn several times per second in order to create and display an image for the

user. The frequency of this repetition per second is called Vertical Frequency or Refresh Rate. Unit: Hz

Example:If the same light repeats itself 60 times per second, this is regarded as 60 Hz.

Horizontal Frequency

The time to scan one line connecting the right edge to the left edge of the screen

horizontally is called Horizontal Cycle. The inverse number of the Horizontal Cycle is

called Horizontal Frequency. Unit: kHz

Interlace and Non-Interlace Methods

Showing the horizontal lines of the screen from the top to the bottom in order is called the Non-

Interlace method while showing odd lines and then even lines in turn is called the Interlace method.

The Non-Interlace method is used for the majority of monitors to ensure a clear image. The Interlace

method is the same as that used in TVs.

Plug & Play

This is a function that provides the best quality screen for the user by allowing the computer and the

monitor to exchange information automatically. This monitor follows the international standard VESA
DDC for the Plug & Play function.

Resolution
The number of horizontal and vertical dots used to compose the screen image is called 'resolution'.

This number shows the accuracy of the display. High resolution is good for performing multiple tasks

as more image information can be shown on the screen.

Example:If the resolution is 1280 X 1024, this means the screen is composed of 1280

horizontal dots (horizontal resolution) and 1024 vertical lines (vertical resolution).
