-Dot Pitch
The image on a monitor is composed of red, green and blue dots. The closer the dots, the higher the res-
olution. 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 mon-
itor 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 1920 x 1200 , this means the screen is composed of 1920 horizontal dots
(horizontal resolution) and 1200 vertical lines (vertical resolution).
-A2
This system uses two carriers to transmit voice data. Countries such as South Korea and Germany use
this system.
-BTSC
