480i / 480p / 720p / 1080i /
1080p____ Each of the scanning
rates above refers to the number of
effective scanning lines that decides
the screen resolution. The scanning
rate may be indicated in i (interlaced)
or p (progressive), depending on the
scanning method.
- Scanning
Scanning refers to a process of
sending pixels that form an image
progressively. A larger number of
pixels will deliver a clearer and more
vivid picture.
- Progressive
In progressive scan mode, all lines
of pixels are scanned one by one
(progressively) on the screen.
- Interlaced
In interlaced scan mode, every other
line of pixels is scanned from top to
bottom first and then the remaining
lines of pixels (that were not scanned)
are scanned.
Non-interlace Mode and Interlace
Mode____ Non-interlace mode
(progressive scan) displays a
horizontal line from the top to the
bottom of a screen progressively.
Interlace mode displays the odd
number lines first and the even
number lines next. Non-interlace
mode is mainly used in monitors as it
produces screen clarity and interlace
mode is mainly used in TVs.
Dot Pitch____ The screen consist of
red, green and blue dots. A shorter
distance between the dots produces
a higher resolution. Dot pitch refers
to the distance between the shortest
distance between dots of the same
colour. Dot pitch is measured in
millimetres.
Vertical Frequency____ The product
displays a single image many times
per second (like a fluorescent light
that flickers) to display an image for
a viewer to see. The rate of a single
image being displayed repeatedly per
second is called vertical frequency
or refresh rate. Vertical frequency is
measured in Hz.
E.g. 60Hz refers to a single image
being displayed 60 times in one
second.
Horizontal Frequency____ The
time required to scan a single line
from the left to the right side of the
screen is called a horizontal cycle.
The reciprocal number of a horizontal
cycle is called horizontal frequency.
Horizontal frequency is measured in
kHz.
Source____ Input source refers to a
video source device connected to the
product such as a camcorder or video
or DVD player.
Plug & Play____ Plug & Play is a
function that allows the automatic
exchange of information between
a monitor and PC to produce an
optimum display environment. The
product uses VESA DDC (international
standard) to execute Plug & Play.
Resolution____ Resolution is the
number of horizontal dots (pixels)
and vertical dots (pixels) that form
a screen. It represents the level of
display detail. A higher resolution
enables more data to be displayed on
the screen and is useful to perform
multiple tasks simultaneously.
E.g. A resolution of 1920 X 1080
consists of 1,920 horizontal pixels
(horizontal resolution) and 1,080
vertical pixels (vertical resolution).
DVD (Digital Versatile Disc)____ DVD
refers to a CD-sized mass storage
disk where you can save multimedia
(audio, video or game) applications
using MPEG-2 video compression
technology.
HDMI (High Definition Multimedia
Interface)____ It is an interface that
can be connected to a digital audio
source as well as a high-definition
video source by using a single cable
without compression.
Multiple Display Control (MDC)____
MDC (Multiple Display Control) is
an application that allows multiple
display devices to be controlled
simultaneously using a PC.
Communication between a PC and
monitor takes place using RS232C
(serial data transmission) and RJ45
(LAN) cables.
