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.

LCD pixel statement  
The LCD unit is produced with high-precision manufacturing techniques.  
Nevertheless, some pixels may occasionally misfire or appear as black or  
red dots. This has no effect on the recorded image and does not constitute  
a malfunction.  
ENERGY STAR (for selected models) is a government program (public/private  
partnership) that gives people the power to protect the environment in a cost  
effective way and without sacrificing quality or product features. Products that  
earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict  
energy efficiency guidelines set by the US Environmental Protection Agency  
(EPA) and the US Department of Energy (DOE). In the average home, 75% of all  
electricity used to power home electronics is consumed while the products are  
turned off. ENERGY STAR qualified home electronic products in the off position  
use up to 50% less energy than conventional equipment. More information

Tips and information for comfortable use  
Computer users may complain of eyestrain and headaches after prolonged use.  
Users are also at risk of physical injury after long hours of working in front of a  
computer. Long work periods, bad posture, poor work habits, stress,  
inadequate working conditions, personal health and other factors greatly  
increase the risk of physical injury.  
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis,  
tenosynovitis or other musculoskeletal disorders. The following symptoms may  
appear in the hands, wrists, arms, shoulders, neck or back:  
numbness, or a burning or tingling sensation  
aching, soreness or tenderness  
pain, swelling or throbbing  
stiffness or tightness  
coldness or weakness  
If you have these symptoms, or any other recurring or persistent discomfort  
and/or pain related to computer use, consult a physician immediately and  
inform your company's health and safety department.  
The following section provides tips for more comfortable computer use.  
Finding your comfort zone  
Find your comfort zone by adjusting the viewing angle of the monitor, using a  
footrest, or raising your sitting height to achieve maximum comfort. Observe  
the following tips:  
refrain from staying too long in one fixed posture  
avoid slouching forward and/or leaning backward  
stand up and walk around regularly to remove the strain on your leg  
muscles  
 
 
ix  
Taking care of your vision  
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive  
room lighting, poorly focused screens, very small typefaces and low-contrast  
displays could stress your eyes. The following sections provide suggestions on  
how to reduce eyestrain.  
Eyes  
Rest your eyes frequently.  
Give your eyes regular breaks by looking away from the monitor and  
focusing on a distant point.  
Blink frequently to keep your eyes from drying out.  
Display  
Keep your display clean.  
Keep your head at a higher level than the top edge of the display so your  
eyes point downward when looking at the middle of the display.  
Adjust the display brightness and/or contrast to a comfortable level for  
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:  
Take short breaks regularly and often.  
Perform some stretching exercises.  
Breathe fresh air as often as possible.  
Exercise regularly and maintain a healthy body.

corresponding slots on the bottom of  
the base.  
Screen position adjustment  
To optimize the viewing position, you can adjust the monitor tilt by using  
both of your hands to hold the edges of the monitor as shown below.  
The monitor can be adjusted to 15 degrees up or 5 degrees down.

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.
