Preset Timing Modes
 ―This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other than 
the specified resolution may degrade the picture quality. To avoid this, it is recommended that you select the optimum resolution specified for your product.
 ― Check the frequency when you exchange a CDT product (connected to a PC) for an LCD product. If the LCD product does not support 85Hz, change the vertical 
frequency to 60Hz using the CDT product before you exchange it with the LCD product.

The screen will automatically be adjusted if a signal that belongs to the following standard signal modes is transmitted from your PC. If the signal transmitted from the PC 
does not belong to the standard signal modes, the screen may be blank with the power LED on. In such a case, change the settings according to the following table by

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.
 - Vertical Frequency
The product displays a single image 
multiple times per second (like a 
fluorescent light) to display what the 
viewer sees. The rate of a single image 
being displayed repeatedly per second is 
called vertical frequency or refresh rate. 
Vertical frequency is measured in Hz.

Optimum Picture Quality and Afterimage 
Burn-in Prevention
Optimum Picture Quality
 •Due to the nature of the manufacturing of this product, approximately 1 pixel per million (1ppm) 
may be brighter or darker on the panel. This does not affect product performance.
 -The number of sub-pixels by panel type: 6,220,800
 • Run Auto Adjustment to improve the picture quality. If noise is still found even after auto 
adjustment, adjust Coarse or Fine.
 •
Leaving the screen fixed on a stationary image for an extended period of time may cause afterimage 
burn-in or defective pixels.
 -Activate power-saving mode or a dynamic screen saver if you will not be using the product for 
an extended period of time.
Prevention of Afterimage Burn-in
What is afterimage burn-in?
Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refers 
to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended period 
of time (more than 12 hours), a slight voltage difference may occur between the electrodes in pixels that 
control the liquid crystals.
Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner. 
When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this, 
the accumulated voltage difference should be reduced.
 ―
Afterimage burn-in should not occur when an LCD panel is operating in proper conditions.

Preventing afterimage burn-in
 ―The best way to protect the product from afterimage burn-in is switching the power off or setting the 
PC or system to run a screen saver when not in use. Also, Warranty service may be limited depending 
on instruction guide.
 • Powering Off, Screen Saver and Power Saving Mode
 -Power off the product for 2 hours after using it for 12 hours.
 -
Go to Display Properties > Power Supply on your PC and set the product to power off as 
required.
 -Using a screen saver is recommended.
It is best to use a single-color or moving-image screen saver.
 • Regular color Change
 -Use 2 colors
Switch between 2 colors every 30 minutes as shown above.

Avoid combinations of a text color and background color of contrasting brightness.
(Brightness: refers to the lightness or darkness of a color which varies depending on the amount of 
light emitted.)

Terminology
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 
T Vs.
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 color. Dot 
pitch is measured in millimeters.
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. Component ports (green, blue and 
red)____ The component ports, which 
identify, transmit and receive contrast 
signals, provide superior picture quality 
to any other video connection methods.
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.
