- RF, DVI-D, PC(Analog), 2Scart, Component,
Video, S-Video

- Brightness : 500cd/

- Contrast Ratio :

23": 800:1, 27": 1000:1, 32": 800:1

- Respense time : 16ms

- Dynamic contrast

- PIP (on PC only)

- TFT-LCD
(Thin film Transistor Liquid Crystal Display)

ADC(Analog to Digital Converter)
This is a circuit that converts from analog signal to
digital signals.

- PLL(Phase Locked Loop)

During progressing ADC, Device makes clock syn­chronizing HSYNC with Video clock

- Inverter

Device that supply Power to LCD panel lamp. this
device gernerate about 1,500~2,000V.

- AC Adapter

Device that converts AC(90V~240V) to DC(+12V
or 14V)

- SMPS(Switching Mode Power Supply)

Switching Mode Power supply. This design tech­nology is used to step up/down the input power by
switching on/off

- FRC(Frame Rate Controller)

Technology that change image frame quantity dis­played on screen for one second.

Actually TFT-LCD panel require 60 pcs of frame
for one second.
so,this technology is needed to convert input
image to 60 pcs regardless input frame quantity.

- Image Scaler

Technology that convert various input resolution to
other resolution.(ex. 640* 480 to 1024*768)

- Auto Configuration(Auto adjustment)

This is an algorithm to adjust monitor to optimum
condition by pushing one key.

- OSD(On Screen Display)

On screen display. customer can control the
screen easily with this.

- Image Lock

This means "Fineness adjustment " in LCD
Monitor, the features are "Fine" and "Coarse"

- FINE

"Fine" adjustment is used to adjust visibility by
control phase difference.

- COARSE

This is a adjustment by tuning with Video colck
and PLL clock.

- DVI (Digital Visual Interface)

This provides a high speed digital connection for
visual data types that is display technology
independent. this interface is primarily forcused at
providing a connection between a computer and
its display device.

- L.V.D.S.(Low Voltage Differential Signaling)

a kind of transmission method for Digital.It can be
used from Main PBA to Panel.

- DVI (Digital Visual Interface)

This provides a high speed digital connection for
visual data types that is display technology inde­pendent. this interface is primarily forcused at pro­viding a connection between a computer and its
display device.

- T.M.D.S
(Transition minimized Differential Signaling)

a kind of transmission method for Digital.
It can be used from Video card to Main PBA.

- DDC(Display data channel)

It is a communication method between Host
Computer and related equipment.
It can make it Plug and Play between PC and
Monitor.

- EDID

Extended Display Identification Data PC can rec­ognize the monitor information as Product data,
Product name,Display mode,Serial number and
Signal source,etc through DDC Line communicat­ing with PC and Monitor.

- 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 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 Non­Interlace 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

Broadcast Television System Committee
The stereo broadcasting system that is used in
most of the countries that have adopted the NTSC
system, including the United States, Canada,
Chile, Venezuela and Taiwan. It also refers to the
organization that has been organized to promote
its development and management.

- EIAJ

Electronic Industries Association of Japan.

- RF Cable

A round signal cable generally used for TV antennas.

- Satellite Broadcasting

Broadcasting service provided via satellite.
Enables high picture quality and clear sound
throughout the country regardless of the location of
the viewer.

- Sound Balance

Balances the levels of the sound coming from
each speaker in televisions with two speakers.

- Cable TV

Whereas the terrestrial broadcasting is delivered
via frequency signals through the air, cable broad­casting is transmitted 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

"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, entertain­ment and educational programs. (Different from
cable TV.)

CATV can be viewed only within the area in which
the CATV service is offered.

- S-Video

Short for "Super Video." S-Video allows up to 800
lines of horizontal resolution, enabling high-quality
video.

- VHF/UHF

VHF indicates TV channels 2 to 13, and UHF indi­cates channels 14 through 69.

- Channel Fine Tuning

This feature allows the viewer to fine-tune the TV
channel to obtain the best viewing conditions. The
Samsung LCD TV has both automatic and manual
channel fine-tuning features to enable the viewer
to adjust their desired settings.

- External Device Input

External device input refers to video input from
such external video devices as VCRs, camcorders
and DVD players, separate from a TV broadcast.
