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
in the box and are in good condition:
•LCD monitor
•Power Cord
•Monitor-To-PC Analog signal cable 15pin

If you find that any item to be missing or appear to be damaged,
contact your dealer immediately. DO NOT throw away the packing
