digital device, pursuant to Part 15 of FCC Rules. These limits are designed to
provide reasonable protection against radio frequency interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy.
If not installed and used in accordance with the instructions, it may cause
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
interference to radio or television reception (this can be determined by turning this
equipment off and on), the user is encouraged to try to correct the interference by one
or more of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.

Handling
Due to its fragile glass panel, this monitor must be handled with caution and not
exposed to impact or shock.
Never touch the display area or rub it with a hard stiff object or tool, as the panel
is easily scratched.
Cleaning
The display area is highly prone to scratching. Do not use ketone-type cleaners
(i.e. acetone), ethyl alcohol, toluene, ethyl acid or methyl chloride to clean the
panel. Doing so may result in permanent damage.
Water, IPA and Hexane are safe cleaners.
Do not allow oil or water to penetrate the display, as droplets cause staining and
discoloration with Time.
Keep food particles and fingerprints away from the display area at all times.
Storage
Store the monitor in a dark place away from sunlight and ultraviolet (UV)
radiation, as air bubbles May develop within the glass panel with time.
Do not store the display in temperatures higher than 40。C / 104。F or humidity
greater than 90%. Avoid condensation.
Caution
1. Do not open any covers on the monitor. No user serviceable parts are inside.
2. In an emergency, disconnect the AC power plug.
3. To avoid electrical shock, disconnect the power cord from the AC adapter
before connecting the signal cable to the computer.
4. Keep away from liquids and flame. Do not immerse this monitor in water or any
other liquid. Do not use this device in excessively hot conditions.
5. Handle the power cord with care. Do not bend the power cord excessively or
place heavy objects on it. Do not use a damaged power cord, as doing so
can result in fire or electrical shock hazards. When disconnecting the power
cord, always grasp the plug, not the cord.
6. The liquid crystals in the display panel contain several irritants. If the panel is
damaged or broken, do not allow the liquid to come in contact with skin, eyes,
or mouth. If you come in contact with the liquid, flush the affected area with

TIMING GUIDE
ENG
The LCD is a multi-frequency display. It operates at horizontal frequencies between
30KHz~80KHz and vertical frequencies between 56Hz~75Hz. Because of its
microprocessor-based design, it offers auto-synchronization and auto-sizing
capabilities. This monitor offers 10 preprogrammed settings that are listed in the
timing table on page 11.
These preset modes cover most of the common video modes supported by popular
graphics adapters. However, each adapter's implementation of these video modes
may vary slightly. If you find it necessary to make minor display adjustments (for
example, horizontal and vertical position), please refer to the On Screen Display
section of this manual for instructions.
If you would like to use one of the preset timing modes, please refer to your video
card manufacturer's installation guide for instructions on how to make these changes.
The video card controls the refresh rate. Most video cards provide a software utility or
hardware DIP switches that allows you to change the frequency used for each
resolution.

* Note :
When resolutions are shown that are lower than the pixel count of the LCD panel, text
may appear choppy or bold. This is normal all current flat panel technologies when
displaying non-native resolutions on a full screen (below than 1280 × 1024
resolution). In flat panel technologies, each dot on the screen is actually one pixel, so
to expand resolutions to full screen, an interpolation of the resolution must be down.
When the interpolated resolution is not an exact multiple of the native resolution the
mathematical interpolation necessary may cause some lines to appear thicker than
others.

ENG
No power.
Flip the power switch ON. The Power LED turns on.
Make sure AC power cord is securely connected to the power jack and to a
power outlet.
Power on but no screen image.
Make sure the video cable attached with this monitor is tightly secured to the
video output port on the back of the computer
Adjust the brightness and contrast.
Image is unstable, unfocused.
Use AUTO-TUNE to adjust automatically.
If the image is still unstable after AUTO-TUNE processing, please adjust PHASE
manually to get image focused.
Check whether the resolution or refresh rate in windows display setting is
beyond supported range (please refer to the specification of supported
mode.)
Flickering
Not enough power is being supplied to the Monitor.
Connect the Monitor to a different outlet. If a surge protector is being used,
there may be too many devices plugged in.
See Timing Guide in this manual with a list of refresh rates and frequency
settings showing the recommended setting for the Monitor.
Wrong or abnormal colors.
If any colors (Red, Green, or Blue) are missing, check the video cable to make
sure it is securely connected. Loose pins in the cable connector could cause a
bad connection.
Connect the Monitor to another computer.
Check the graphics card for proper sync scheme (or sync polarities) to match
the Monitor's specifications.
Double (split) screen image
Make sure your graphics card is set to Non-Interlaced mode.

reference
ENG
Entire screen image rolls (scrolls) vertically.
Make sure the input signals are within the LCD monitor's specified frequency
range. (Maximum : VESA, MAC 1280×1024 @ 75Hz)
Connect the video cable securely.
Try the Monitor with another power source.
Control buttons do not work.
Press only one button at a time.
ABOUT THE LCD
The LCD contains over 3,932,160 thin-film transistors (TFTs).
A small number of missing, discolored, or lighted dots on the screen is an intrinsic
characteristic of TFT LCD technology and is not an LCD defect.
If you display a fixed pattern for more than 10 hours, its image may remain on the
screen in overlap mode when you display something else.
