it to the monitor. The monitor displays the color signals
by separating the composite signal into original color
signals.
The image on a monitor is composed of red, green and blue
dots. The closer the dots, the higher the resolution. The dis-
tance between two dots of the same color is called the 'Dot
Pitch'. Unit: mm
The screen must be redrawn several times per second in
order to create and display an image for the user. The fre-
quency of this repetition per second is called the Vertical
Frequency or Refresh Rate. Unit: Hz
Example: If the same light repeats itself 60 times per sec-
ond, this is regarded as 60 Hz.
The time to scan one line connecting the right edge to the
left edge of the screen horizontally is called the Horizontal
Cycle. The inverse number of the Horizontal Cycle is called
Horizontal Frequency. Unit: kHz
Showing the horizontal lines of the screen from the top to
the bottom sequentially 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 Inter-
lace 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 ex-
change information automatically. This monitor follows the
international standard VESA DDC for the Plug & Play func-
tion.
The number of horizontal and vertical dots used to compose
the screen image is called the 'resolution'. This number
shows the accuracy of the display. A 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 res-
olution) and 1200 vertical lines (vertical resolution).
A round signal cable generally used for TV antennas.
Balances the levels of the sound coming from each speaker
in televisions with two speakers.
Whereas the terrestrial broadcasting is delivered via fre-
quency signals through the air, cable broadcasting is trans-
mitted via a cable network. In order to view cable TV, one
must purchase a cable receiver and hook it up to the cable
network.
"CATV" refers to the broadcasting service offered at hotels,
schools and other buildings through their own broadcasting
system, apart from VHF or UHF broadcasting by terrestrial
broadcasters. The CATV programs may include movies,
