- 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 sec-
ond 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).
- BTSC
