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.

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.

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, and plug the other end
into an 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.
Please confirm the distribution system in building installation shall provide
the circuit breaker rated 120/240 V, 20 A (maximum).
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.
In order to prevent damage to the monitor, do not lift the monitor by its
base.
CLEANING YOUR MONITOR
Please carefully follow the below guidelines when cleaning the monitor.
Always unplug the monitor before cleaning.
Use a soft cloth to gently wipe the screen and cabinet front and sides.
NEVER SPRAY OR POUR ANY LIQUID DIRECTLY ONTO THE SCREEN OR
CASE.
PLEASE DO NOT USE ANY AMMONIA OR ALCOHOL-BASED CLEANERS ON
THE LCD DISPLAY SCREEN OR CASE.
Acer will not be liable for damage resulting from use of any ammonia or
alcohol-based cleaners.
EN-6
POWER SAVING
The monitor will be driven into “Power Saving” mode by the control signal
from the display controller, as indicated by the amber-color power LED.
The power saving states will be kept until a control signal has been detected
or the keyboard or mouse is activated. The recovery time from Active OFF
state back to ON state is around 3 seconds.
DDC
To make your installation easier, the monitor is able to Plug and Play with
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.
