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  
EN-3  
 
X243W  
take short rests to relax your neck and shoulders  
avoid tensing your muscles or shrugging your shoulders  
install the external display, keyboard and mouse properly and within comfort  
able reach  
if you view your monitor more than your documents, place the display at the  
center of your desk to minimize neck strain  
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.  
-----------------------------------------------------------------------------------------------------  
Warning! We do not recommend using the product on a couch or bed. If this is  
unavoidable, work for only short periods, take breaks regularly, and do some  
stretching exercises.

CONNECTING THE POWER CORD  
Check first to make sure that the power cord you use is the correct type  
required for your area.  
This monitor has a universal power supply that allows operation in either  
100/120V AC or 220/240 V AC voltage area. No user-adjustment is required.  
Plug one end of the power cord to the AC Inlet, plug another end to a  
proper AC outlet.  
For unit using at 120 V AC:  
Use a UL Listed Cord Set, Type SVT wire and plug rated 10 A/125 V.  
For unit using at 220/240 V AC (outside of U.S.):  
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.  
SAFETY PRECAUTION  
Avoid placing the monitor, or any other heavy object, on the power cord  
to avoid damage to the cable.  
Do not expose the monitor to rain, excessive moisture, or dust.  
Do not cover the ventilation slots or openings of the monitor. Always  
put the monitor in a place where there is adequate ventilation.  
Avoid placing the monitor against a bright background or where sun-  
light or other light sources may reflect on the face of the monitor. Place  
the monitor just below eye level.  
Handle with care when transporting the monitor.  
Refrain from giving shock or scratch to the screen, as screen is fragile.

your system if your system also supports DDC protocol. The DDC (Display  
Data Channel) 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  
DDC2B standard.

Standard Timing Table  
To reduce the need for adjustment for different modes, the monitor has  
default setting modes that are most commonly used as given in the table  
below. For optimum adjustment, the user is suggested to perform the  
Auto Setup under Windows “Full Screen“ pattern or using the pattern in  
the floppy disk provided. When none of the mode is matched, the user can  
store their preferred modes in the user modes. The monitor is capable of  
storing up to 9 user modes. The only condition to store as a user mode is  
the new display information must have 1 KHz difference for horizontal  
frequency or 1 Hz for vertical frequency or the sync signal polarities are  
different from the default modes.
