Using The Display
Turning the Display On and Off
Use the power button located at the lower right side of the front panel of the
display to turn the display on and off. When the display is on, the LED near the
Power button is illuminated. The indicator will illuminate green when both the
display is active and amber when the display is in reduced power mode.(PC only)
Note：For PC use only.
If the PC supplies power saving signals to the display, the display’s power
management features reduce power consumption to low levels when the PC
goes into its power-saving mode. See “Minimizing Power Consumption” on page
7 for more information.
If the PC doesn’t use industry standard power-save signaling techniques, power
consumption can be reduced by turning off the display when not in use.
Note: Because of the technology used in LCD panels, screen savers will
not prolong the life of the display. So if the display will not be used for
an extended period, be sure to turn it off.
Warning
To completely disconnect power from the display, you must
remove the power cord from the wall outlet and then remove the
power cable from the display.

ENGLISH
Setting the Video Mode (PC only)
Since the inherent format of this display is 1024 pixels by 768 lines, the display
will perform best when a PC is set to a screen resolution of 1024 x 768. If using a
lower resolution (such as 640 x 480), the image is expanded to fill the screen
The display supports many common video modes, as shown in “Video Modes” on
page 17 Check the documentation supplied with the PC and video adapter card
to find out which modes they support.
To check the video mode of the PC, please check the Windows’ settings feature.
Setting the Refresh Rate (PC only)
The image refresh rate is the number of times per second that the image is
refreshed; it is also known as the vertical frequency.
On standard CRT displays, we recommend that the highest possible refresh rate
supported by your PC at the current screen resolution should be used. This is
necessary to avoid screen flickering and to minimize eyestrain. However, with an
LCD Monitor, flicker is not an issue. It is flicker-free at all supported refresh rates.
The table in “Video Mode” on page 17 shows the image refresh rates supported
by the display at different screen resolution. Although this LCD monitor supports
up to 75 Hz for analogue video input, we recommend that is used at 60 Hz refresh
rate for best performance.
To set the refresh rate with a standard Windows installation, follow the steps
mentioned in the Windows’s or graphic card’s user’s manual.
Minimizing Power Consumption (PC only)
Many PCs support industry standard power-save signaling techniques. Power
management features reduce the display’s power consumption after a period of
keyboard inactivity.
When the display is in a power-saving mode, the screen is blank and the power
indicator is amber. Pressing a key on the keyboard or moving the mouse restores
the image in several seconds. Consult the PC documentation for information
about setting the power-saving modes.
The display accepts the signals for the three standard power-saving modes –
Standby, Suspend, and Sleep. For any of these conditions, the display will go into
Sleep mode.

Warning
Don’t use liquid, aerosol, or abrasive cleanin
g
solutions to clean the
screen.
Caring for and Cleaning the Display
To maximize screen life and prevent damage to the LCD panel, we recommend
to:
ÖUse the display power management system (if available on the PC).
ÖIf a power management system is not used, turn off the display when it won’t
be used for an extended period.
ÖDon’t press, rub, or poke the display with fingers or other objects.
ÖHandle the display with care.
The LCD module is a high-quality optical device that requires special care when
cleaning.
To clean the screen:
1. Turn off and unplug the display.
2. Gently dust the screen with a dry, soft, line-free cloth.
Note: If the screen is still dirty, a dampened cloth with several drops of
distilled water can be used. Make sure the LCD panel is completely
dry before turning back on.

Troubleshooting
This chapter contains information about how to troubleshoot your LCD Monitor. If
you have tried all of the items listed below, please contact a qualified service
personnel.
A. My display doesn’t work, even though the computer appears to work.
1. Make sure the power cable is securely plugged into the display.
2. Make sure the display is turned on.
3. Try turning the display off and then turning it on again.
4. Make sure the display’s power cord is plugged into a power outlet and into
the AC power adapter. Check to see whether the outlet works by plugging
another device (such as a lamp) into the outlet. (If the light on the front of
the display is lighted, it is getting power. Try the next item on this
procedure.)
5. Check the cable connection between the display and the computer. The
cable connectors must be pushed in all the way.
B. The message “No Sync” appears on my display.
This message appears when there is no video signal from the computer with
cable already connected.
1. Make sure that the computer's power is turn on.
2. Make sure that your graphic card has its output already.
C. The message “Signal Out of Range” appears on my display.
This message appears when the input signal is beyond the display's
capability.
Set your PC to a supported video mode, preferably 1024 x 768 at 60 Hz. See
“Setting the Video Mode” on page 7.
D. The image is very unstable.
1. Set your PC to a supported video mode, preferably 1024 x 768 at 60 Hz.
See “Setting the Video Mode” on page 7.
2. Restore the original factory settings by choosing Recall Factory Setting
in the OSD “Management” submenu.
3. Perform the Auto Setup function. See “Direct Function Access using the
Left and Right Buttons” on page 15.

Unknown Video Modes
Like all other monitors, the your LCD monitor is designed to work with standard
video modes. However, not all video/graphic cards use only standard display
modes.
Your LCD monitor uses state-of-the-art technology, which is designed to
synchronize to any display mode. We recommend choosing one of the supported
modes listed above. If you choose an unknown mode, you will need to manually
adjust the clock, phase, and image position.
If you must use an unknown mode, you can run Auto Setup at first. If Auto Setup
doesn’t provide adequate image adjustment, then you must manually adjust the
clock, phase, horizontal position, and vertical position.
