Special notes on LCD monitors
The following are normal with the LCD monitor and do not indicate a problem.
•
Due to the nature of the fluorescent light, the screen may flicker during
initial use. Turn off the power switch and then turn it on again to make
sure the flicker disappears.
•
•
•
You may find slightly uneven brightness on the screen depending on the
desktop pattern you use.
The LCD screen has 99.99% or more effective pixels. It may include
blemishes of 0.01% or less such as a missing pixel or a pixel lit all the time.
Due to the nature of the LCD screen, an afterimage of the previous screen
may remain after switching the image, when the same image is displayed
for hours. In this case, the screen is recovered slowly by changing the image
or turning off the power switch for a few hours.

enhanced text readability and graphics clarity.
Eliminate glare and reflections by:
•
placing your display in such a way that the side faces the window or
any light source
•
•
•
•
•
minimizing room light by using drapes, shades or blinds
using a task light
changing the display's viewing angle
using a glare-reduction filter
using a display visor, such as a piece of cardboard extended from the
display's top front edge
•
•
Avoid adjusting your display to an awkward viewing angle.
Avoid looking at bright light sources, such as open windows, for extended
periods of time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing
and productive:

Connecting the power cord
•
Check first to make sure that the power cord you use is the correct type
required for your area.
•
The monitor has a universal power supply that allows operation in either
100/120 V AC or 220/240 V AC voltage area. No user-adjustment is
required.
•
•
•
Plug one end of the power cord to the AC inlet, and plug the other end
into an AC outlet.
For units using 120 V AC:
Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.
For units using 220/240 V AC:
Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The
cord set should have the appropriate safety approvals for the country in
which the equipment will be installed.
Power saving
The monitor will be switched to "power saving" mode by the control signal
from the display controller, as indicated by the amber-colored power LED.

The power saving mode will be kept until a control signal has been detected or
the keyboard or mouse is activated. The recovery time from "power saving"
mode back to "on" is around 3 seconds.
Display Data Channel (DDC)
To make installation easier, so long as your system supports the DDC protocol,
the monitor is able to plug-and-play. The DDC is a communication protocol
through which the monitor automatically informs the host system about its
capabilities; for example, supported resolutions and corresponding timing. The
monitor supports the DDC2B standard.
