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

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

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.

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.

Under normal conditions, stereoscopic 3D viewing is safe for any duration that
you would usually view your display. However, some people may experience
discomfort. To minimize the potential for experiencing visual problems or any
adverse symptoms:
• Take the stereoscopic 3D medical test to verify your ability so see
stereoscopic 3D images.
• Maintain a distance no closer than 2 to 2.5 feet away from the display.
Viewing from too close a distance can strain your eyes.
• Take regular breaks, at least 5 minutes after every hour of stereoscopic 3D
viewing.
• If you experience any of the following symptoms, do not engage in any
potentially hazardous activity (for example, driving a vehicle) until your
symptoms have subsided:
• Nausea, dizziness or queasiness
• Headache or eyestrain
• Blurry vision
Double vision that lasts longer than a few seconds
If symptoms persist, discontinue use and do not resume stereoscopic 3D viewing
without discussing your symptoms with a doctor.

The Acer 3D monitor you have purchased supports NVIDIA 3D Vision technology
to deliver a fully immersive stereoscopic 3D experience. And, with the use of
high-tech wireless glasses, the 3D Vision kit transforms hundreds of PC games
and digital photographs into an eye-popping interactive experience.
Just slip on the glasses to see characters and environments come to life on the
screen.
3D Vision automatically transforms hundreds of PC games into full stereoscopic
3D. Visit www.nvidia.com/3dvision for a full list of supported games and
applications.
Wireless glasses
Charging the glasses
Note: We recommend that you fully charge your glasses now since
it will take approximately three hours to complete. The wireless
glasses hold approximately 40-hours of gaming per full charge.
The wireless glasses require periodic charging. To charge the glasses, use one of
the USB cables that came with the kit. Plug one end into the glasses and the
other to any USB port on your PC. You can also use a USB wall adapter to
charge your glasses. Charge your glasses until the amber charge light goes out.
You can use wireless glasses while they are being charged.

If you are charging the wireless glasses by connecting them to your PC using a
USB cable, make sure your PC does not go into power save mode. When your PC
goes into power save mode, the wireless glasses are no longer charging. To fix
this, disable any power-saving options on your PC under the Windows Control
Panel. Alternatively, you can use a USB wall charging device to charge the
glasses directly from your wall power outlet without connecting to the PC. You
can use your glasses while they are charging.
Using the glasses
It is a good idea to keep the glasses in the protective pouch when you are not
using them. When wearing your glasses, you must be in line-of-sight with the IR
emitter. Press the ON button to turn the glasses on. The glasses turn off
automatically when there is no activity.
Warning: The wireless glasses are not prescription eye wear,
sunglasses, nor protective goggles. Do not use the glasses for any
general eye wear purposes (e.g. driving, reading, protection from
sunlight or ultraviolet light, etc.) as such use may result in injury.

NVIDIA recommends you register your wireless glasses for support at
www.nvidia.com/3dvision/register.
3D Vision is not working
Re-evaluate your setup: Ensure there is direct line-of-sight between the IR
emitter and your wireless glasses at a range of at least 1.5 feet (45 cm) or
greater. Any obstruction may cause the lenses to flicker or turn off.
Do not place objects in front of the emitter, as this could block the signal. Also,
make sure not to place your hand or other objects in front the of the IR receiver
on the glasses; this is located near the front left lens. Ensure your wireless
glasses are fully charged.
You can check the battery level of your glasses by pressing the ON button.
• If the light next to the button is green, you have up to 40 hours of battery
life remaining. Actual battery life is dependent on the recharge time.
• If the light is red, you have less than two hours remaining and it is
recommended that you recharge your glasses.
• If the light does not turn on, the battery is drained and the glasses must be
recharged.
If you are charging the wireless glasses by connecting them to your PC using a
USB cable, make sure your PC does not go into power-save mode. When your PC
goes into power-save mode, the wireless glasses are no longer charging. To fix
this, disable any power-saving options on your PC under the Windows Control
Panel. Alternatively, you can use a USB wall charging device to charge the
glasses directly from your wall power outlet without connecting to the PC.
Excessive flickering
Flicker in your peripheral vision can be caused by differences in frequencies at
which 3D Vision operates and the lighting in your room. This type of flicker can
be avoided by turning off the lights or changing the stereoscopic 3D refresh
rate. To see the refresh rates, run the Setup Wizard from the NVIDIA Control
Panel. When you get to the page asking about flicker, select Yes. You can then
select from the following refresh rates:
Page 36
English
• 120 Hz refresh rate for use in North America when lights are on
• 110 Hz refresh rate for daytime and when lights are off
• 100 Hz refresh rate for countries with 50 Hz lighting and
when lights are on
Once you have selected a refresh rate on the Setup Wizard screen, click Test to
verify the new refresh rate which also helps reduce flickering. Once you have
found the best setting, click Next to continue.
Eyestrain/headache
If you are experiencing eyestrain or headaches, it could be due to excessive
depth amount set to view the stereoscopic 3D.
Warning: If eyestrain and headaches persist, discontinue viewing
in stereoscopic 3D and consult a doctor.
