Note: Design and specifications are subject to change without prior notice. PowerSaver This monitor has a built-in power management system called PowerSaver. This system saves energy by switching your monitor into a low-power mode when it has not been used for a certain amount of time. The monitor automatically returns to normal operation when you press a key on the keyboard. For energy conservation, turn your monitor OFF when it is not needed, or when leaving it unattended for long periods. The PowerSaver system operates with a VESA DPMS compliant video card installed in your computer. Use a software utility installed on your computer to set up this feature.

Terms
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 1280 x 1024 , this means the screen is composed of 1280
horizontal dots (horizontal resolution) and 1024 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: 1280 x 1024
{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
3,932,160.
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 picture, you can get better quality of picture by executing auto adjustment function in display screen that is appeared as window termination button is pressed. If theres still noise after auto matic adjustment, use FINE/COA RSE 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 en ergy save or set a screensaver to movin g 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 24 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
