Terms
Sync Signal Sync (Synchronized) Signals refer to the standard signals
that are required to display desired colors on the monitor.
They are divided into Vertical and Horizontal Sync Signals.
These signals display normal color images by the set reso-
lution and frequency.
Types of Sync Signals Separate
• This is a scheme of transmitting individual vertical and
horizontal sync signals to the monitor.
Composite
• This is a scheme of combining vertical and horizontal
sync signals into one composite signal and transmitting
it to the monitor. The monitor displays the color signals
by separating the composite signal into original color
signals.
Dot Pitch 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
Vertical Frequency 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.
Horizontal Frequency 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
Interlace and Non-Interlace
Methods
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.
Plug & Play 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.
Resolution 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.
