The LCD Monitor
Your New LCD Monitor
Your LCD Monitor has been designed to be versatile, ergonomic and
user-friendly. The LCD Monitor is capable of displaying most
standards, from 640x350 VGA to 1680x1050 WSXGA+. The digital
controls located on the front panel allow the user to easily adjust the
Monitor’s display parameters, and the LCD Monitor’s small footprint
gives you more room in your workspace for other peripherals.
Lightweight and compact, the LCD Monitor is the perfect solution for
users on the go. You can use the LCD Monitor for everything from
making business presentations to playing computer games. The
Monitor also has a wall-mountable stand for added convenience.
The architecture of the LCD Monitor incorporates an LCD panel that
produces a clear display with low radiation emission. And with its low
power consumption, the LCD Monitor helps you reduce your power bill.
Unpacking
Before unpacking your LCD Monitor, prepare a suitable workspace
for your LCD Monitor and computer. Look for a stable, level and clean
surface near a wall outlet. Even though the LCD Monitor uses very
little power, you should put it in a location, which allows sufficient
airflow to ensure that the LCD Monitor and your computer do not
overheat. Set up your LCD Monitor so that the panel is not facing a
window where sunlight often comes in. The glare caused by sunlight
reflecting off of the LCD Monitor’s screen will make it difficult to use
the Monitor for viewing.

Note: Using a computer for an extended period of time with a poor workstation
set-up and incorrect working habits can cause health problems. The science of
ergonomics studies the relationship between health and a suitable working
environment. There is a section on ergonomics at the end of this chapter. For
more information on ergonomics, contact your nearest computer bookstore, or
local library. The Internet also has information on this and other subjects.
If you previously were using a CRT monitor instead of a LCD monitor,
please do not connect the LCD monitor to your computer yet. Please
use the CRT monitor and turn on your computer. Make sure your video
card’s refresh rate is at 60hz in the Display Setting’s Advance Menu
under the Display Adapter tab. Once that is achieved you can then turn
off the computer and plug your new LCD monitor in
After unpacking your LCD monitor, make sure the following items are included

Troubleshooting
This LCD monitor comes pre-adjusted with standard VGA timing. Due to
output timing differences among various VGA cards, you may initially
experience an unstable or unclear display when a new display mode or new
VGA card is selected.
Before applying any of the following troubleshooting procedures, you should
first apply the Auto Adjust option in the OSD menu.
PROBLEM: Display is unclear and unstable
To stabilize and clarify your display, open the OSD and adjust the clock and
phase to obtain a clear display or change the resolution to the display’s optimal
setting 1680 x 1050 at 60hz. Make sure you use auto adjust function after
changing the resolution.
PROBLEM: There is no LCD display
If there is no display on the LCD, refer to the following:
1. Make sure that the power indicator on the LCD monitor is lit,
that all connections are secure, and that the system is running
on the correct timing. Refer to Appendix B for information on
timing.
2. Turn off the LCD monitor and then turn it back on again. Press
the OSD Menu button (refer to Chapter 2) once and then press
one of the Adjustment Control buttons several times. If there is
still no display, press the other Adjustment Control button
several times.
3. If step 2 does not work, connect your PC system to another
external CRT. If your PC system functions properly with a CRT
monitor but it does not function with the LCD monitor, and the
LCD monitor’s power LED is blinking, the output timing of the
19
Rev.3
PC’s VGA card may be out of the LCD’s synchronous range.
Change to one of the alternate modes listed in Appendix B, or
replace the VGA card and repeat steps 1 and 2.
4. If the power LED is not lit, check that the AC power connector is
securely connected, and verify that the AC adapter LED is lit. If
the AC adapter LED is not lit, please contact your dealer for
assistance.
PROBLEM: The LCD displays “signal out of range” error message
1. If you have a CRT monitor, please connect the CRT monitor to
the computer and change the refresh rate down to 60hz via
your video card’s display settings menu. After the setting of
60hz has been change you can then use the LCD on the
computer.
2. If you do NOT have a CRT monitor, please make sure both the
X20WG-Naga and your computer is turned off. Afterwards turn
on the LCD and the computer.
3. While the computer is turned on, press the “F8” key on your
keyboard continuously until a selection menu appears and
select the “Safe Mode” option.
4. When you’ve entered Safe Mode please uninstall any video
card driver and monitor driver by using either the “Add /
Remove Programs” icon or going into “System Properties” and
manually removing anything under “Monitors” and “Display
Adapters”.
5. After removing all the drivers, please reboot your computer and
you should be able to see windows. Please then procede to
install your monitor driver first, then your video card driver.
Please remember to make sure your refresh rate should be at
60hz.
