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.

Acer monitor is purposed for video and visual display of information obtained from electronic devices.

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 video 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

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
Use 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.

Unpacking
When you unpack the box, ensure that the following items are present, and retain the packing materials for future shipment.

Installing/removing the base

Note: Unpack the monitor and base first. Carefully place the monitor face down on a flat surface – use a cloth pad to prevent scratching the screen.

Attach the monitor stand arm to the base.
Secure the base to the arm of the monitor stand base.
Note: If using a wall-mounting kit for installation, we recommend using a VESA mounting kit (75 mm × 75 mm) and M4 × 10 (L) mm screws to secure the monitor to the wall.

Note: Carefully place the monitor face down on a flat surface – use a cloth pad to prevent scratching the screen.

Press the release latch with a screwdriver.

Please first ensure the power cord you are using is the correct type required in your area.
This monitor uses universal power and can run on 100/120 volts or 220/240 volts AC. The user does not need to make any adjustments.

Plug one end of the power cord into the AC power input, and plug the other end into an AC power outlet.
Areas where 120 volts are used: Use a UL-compliant power cord kit, including SVT-type leads and a 10-amp/125-volt plug.
Areas using 220/240 volts (outside the United States):

Use a power cord kit consisting of an H05VV-F cord and a 1 amp, 250-volt plug.
This power cord kit must meet the safety standards for the country where you are installing the device.

DC power supply
Use the power adapter provided by the manufacturer, the specifications are:

22 inch/24 inch	Input: 100-240 V	Output: 12 V 2.0 A
27 inch/32 inch	Input: 100-240 V	Output: 12 V 3.5 A

Safety precautions

Avoid placing the monitor or any other heavy objects on the power adapter, as this may cause fire or electric shock.
Do not expose the monitor to rain, excessive humidity or dust, as this may cause fire or electric shock.
Do not cover slots or openings on the monitor to facilitate normal heat dissipation. Place the monitor in a well-ventilated location.

Avoid placing the display in front of an overly bright background, or where direct sunlight or other light sources may shine on the display surface. Place the monitor directly below your line of sight when staring straight ahead.
Use extreme caution when handling the monitor.
Please avoid hitting the display, and do not scratch the screen surface. The screen is fragile.

To prevent damage to the monitor, do not lift the monitor using the stand.

Cleaning the display

When you clean the monitor, follow the instructions carefully.

Before cleaning, unplug the monitor’s power adapter.
Use a soft cloth to gently wipe the screen and the front and sides of the case ever spill any liquid directly onto or into the screen or its case.
Do not use any ammonia- or alcohol-based cleaners on the LCD monitor screen or case.

Acer is not responsible for damage caused by the use of any ammonia- or alcohol-based cleaners.
