1. Appropriate Operation
(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4)Use only a high quality, safety approved AC/DC power cord.
(5)Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:
- Extremely hot, cold or humid environment.
-Areas containing excessive dust and dirt.
- Near any appliance generating a strong magnetic field.
- In direct sunlight.
2. Caution
No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly familiar
with all of the following safety checks and servicing guidelines.
3. Safety Check
Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage is
exposed in such areas as the associated transformer circuits.
4. LCDModule Handling Precautions
4.1 Handling Precautions
(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2)Be sure to turn off power supply when connecting or disconnecting input connector.
(3)Wipe off water drops immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6)Since CMOSLSI isusedinthis module, take care of static electricity and ensure human earth when handling.
(7)Do not open or modify the Module Assembly.
(8)Do not press the reflector sheet at the back of the module in any direction.
(9)In the event that a Module must be put back into the packing container slot after it was taken out of the
container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the
CFL Reflector edge softly. Otherwise the TFT Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate or tilt the Interface
Connector of the TFT Module.

(11) After installation of theTFT Module intoan enclosure(LCDmonitor housing, for example), do not twist or
bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration
that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise theTFT Module
may be damaged.
(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local
ordinances or regulations fordisposal.
(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module
should be supplied with power that complies with the requirements of Limited Power Source
(IEC60950 or UL1950), or an exemption should be applied for.
(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950
or UL1950). Do not connect theCCFL to a HazardousVoltage Circuit.

Correct methods : Incorrect Methods :
Only touch the metal frame of the panel or the front
cover of the monitor.
Do not touch the surface of the polarizer .
If the surface of the panel is pressed by fingers, this
may cause "MURA."
Take out the monitor by grasping the cushion. If the monitor is removed by grasping the LCD
panel, that may cause "MURA."

Do the following to adjust the screen image:
1. To display the Main Menu, press button [1].
NOTE: All OnView menus and adjustment screens disappear automatically after about 30
seconds. This is adjustable through the OSD timeout setting in the setup menu.
2. To select a control you want to adjust, pressSorTto scroll up or down the Main Menu.
3. After the control is selected, press button [2]. A control screen like the one shown below
appears.
4. To adjust the control, press the upSor downTbuttons.
5. To save the adjustments and exit the menu, press button [1] twice.
The following tips may help you optimize your display:
• Adjust your computer's graphic card so that it outputs a video signal 1280 x 1024 @ 60Hz
to the LCD display. (Look for instructions on “changing the refresh rate” in your graphic
card's user guide.)
• If necessary, make small adjustments using H. POSITION and V. POSITION until the
screen image is completely visible. (The black border around the edge of the screen should
barely touch the illuminated “active area” of the LCD display.)
The line at the bottom of the screen shows the
current functions of buttons 1 and 2: Exit or select
the Brightness control.

Main Menu Controls
Adjust the menu items shown below by using the upSand downTbuttons.
Control Explanation
Auto Image Adjust automatically sizes, centers, and fine tunes the video signal
to eliminate waviness and distortion. Press the [2] button to execute the Auto Image
Adjust function.
NOTE:
1. Auto Image Adjust works with most common video cards. If this function
does not work on your LCD display, then lower the video refresh rate to 60
Hz and set the resolution to its pre-set value.
2. The Auto Image Adjust and most Manual Image Adjust functions are not
available for DVI input.
Contrast adjusts the difference between the image background (black level)
and the foreground (white level).
Brightness adjusts background black level of the screen image.
InputSelect toggles between analog and digital input signals.
sRGB-RGB is quickly becoming the industry standard for color management,
with support being included in many of the latest applications. Enabling this
setting allows the LCD display to more accurately display colors the way they
were originally intended. Enabling the sRGB setting will cause the Contrast and
Brightness adjustments to be disabled.
9300K-Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).
6500K-Adds red to the screen image for warmer white and richer red.
5400K-Adds green to the screen image for a darker color.
Color Adjust provides several color options, including preset color
temperatures and RGB mode which allows the red (R), green
(G), and blue (B) levels to be adjusted independently. The factory
setting for this productis6500K (6500Kelvin).

1. To select color (R, G or B) press button [2].
2. To adjust selected color, pressSorT.
Important: If you select RECALL from the Main Menu when the product is set
to a Preset Timing Mode, colors return to the 6500K factory preset.
Manual Image Adjust displays the Manual Image Adjust menu.
Information displays the timingmode(video signalinput)
coming from the graphics card in your computer. See your
graphic card’s user guide for instructions on changing the
resolution and refresh rate (vertical frequency).
NOTE: VESA 1280 x 1024 @ 60 Hz (recommended) means
that the resolution is 1280 x 1024 and the refresh rate is 60
Hertz.
