- Dot Pitch

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.

This is a function that provides the best quality
screen for the user by allowing the computer and
the monitor to exchange information automatical-
ly. 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 'resolu-
tion'. This number shows the accuracy of the dis-
play. High resolution is good for performing mul-
tiple 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 horizon-
tal dots (horizontal resolution) and 1024 vertical
lines (vertical resolution).
