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 
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 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 1440 X 900 , this means the screen is composed of 1440 
horizontal dots (horizontal resolution) and 900 vertical lines (vertical resolution).
 
 
 For Better Display 
 
 
						

							1. Adjust computer resolution and screen injection rate (refresh rate) oncomputer as described 
below to enjoy the best quality of picture. You can have an uneven quality of picture in the 
screen if the best quality of picture is not provided in TFT-LCD.  
 
{Resolution: 1440 X 900  
{Vertical frequency (refresh rate): 60 Hz 
 
2. TFT LCD panel manufactured by using advanced semiconductor technology with precision of 
1ppm (one millionth) above is used for this product. But the pixels of RED, GREEN, BLUE 
and WHITE color seem to be bright sometimes or some of black pixels could be seen. 
This is not from bad quality and you can use it without uneasiness. 
 
{For example, the number of TFT LCD sub pixels that is contained in this product are 
3,888,000.  
 
3. When you clean the monitor and the panel outside, please apply the recommended small 
amount of cleaner by using soft and dry cloth and polish it. Let LCD area not to be forced but 
to be scrubbed out softly. 
If excessive force is applied, you can have a stain on it. 
 
4. If you are not satisfied with the quality of the picture, you can get better quality of the picture 
by executing auto adjustment function in display screen that is appeared as window 
termination button is pressed. 
If theres still noise after automatic adjustment, use FINE/COARSE adjustment function.  
 
5. If you view a fixed screen for an extended period of time, residual image or blurriness may 
appear. 
Change the mode to energy save or set a screensaver to move the picture when you need to 
be away from the monitor for an extended period of time.

							PRODUCT INFORMATION (Image Retention Free) 
 
LCD Monitors and TVs may have image retention when switching from one image to another 
especially after displaying a stationary image for a long time.  
This guide is to demonstrate correct usage of LCD products in order to protect them from Image 
retention.  
 
WarrantyWarranty does not cover any damage caused by image retention.  
Burn-in is not covered by the warranty. 
What is Image retention ? 
During normal operation of a LCD panel, pixel image retention doesnt occur. However, 
if the same image is displayed for a long time, a slight difference in electric charge 
accumulates between the two electrodes which encase the liquid crystal. This may 
cause the liquid crystal to build up in a certain areas of the display. Thus, the previous 
image is retained when switching to a new video image. All display products, including 
LCD,are subject to image retention. This is not a product defect.  
Please follow the suggestions below to protect your LCD from image retention  
Power Off, Screen Saver, or Power Save Mode 
Ex) 
zTurn the power off when using a stationary pattern. 
zUse a Screen saver if possible 
zSet the Monitor to power off with the PC Display Properties Power Scheme.  
 - Turn the power off for 4 hours after 20 hours in use 
- Turn the power off for 2 hours after 12 hours in use  
- Screen saver in one color or a moving image is recommended.  
Suggestions for specific applications 
Ex) Airports, Transit Stations, Stock Markets, Banks, and Controlling Systems  
We recommend that you follow set up of your display system program as below: 
 
 
Display Information together with Logo or Moving image cycle. 
Ex) Cycle : Display Information for 1 hour followed by a  
Display Logo or moving image for 1 minute.  
 
Change the Color Information periodically (Use 2 different colors). 
Ex) Rotate the Color Information with 2 colors every 30 minutes.  
 
Avoid using a combination of characters and background color with large 
difference in luminance. 
Avoid using Grey colors, which can cause Image retention easily.  
 
zAvoid: Colors with big difference in luminance (Black & White, Grey)  
Ex)  
 
 
zRecommended settings: Bright colors with little difference in luminance  
- Change the characters color and background color every 30 minutes  
Ex) 
 
 
- Every 30 minutes, change the characters with movement.  
 
						

							Ex)
The best way to protect your monitor from Image retention is to set your PC or 
S
ystem to operate a Screen Saver program when you are not using it.
Image retention may not occur when a LCD panel is operated under normal conditions. 
 
Normal conditions are defined as continuously changing video patterns. When the LCD 
panel is operated for a long time with a fixed pattern (-over 12 hours-), there may be 
slight difference in voltage between electrodes that work the liquid crystal (LC) in a 
pixel. The voltage difference between electrodes increases with time, forcing the liquid 
crystal to lean. When this occurs, the previous image may be seen when the pattern is 
changed.  
To prevent this, the accumulated voltage difference must be decreased. 
 
Our LCD Monitor satisfies ISO13406-2 Pixel fault Class II
