Safety instructions  
WARNING: Use of controls, adjustments, or procedures other than those  
specified in this documentation may result in exposure to shock, electrical  
hazards, and/or mechanical hazards.

and can be damaged if dropped or hit sharply.  
• Always be sure that your monitor is electrically rated to operate with the AC  
power available in your location.  
• Keep the monitor in room temperature. Excessive cold or hot conditions can have  
an adverse effect on the liquid crystal of the display.  
• Do not subject the monitor to severe vibration or high impact conditions. For  
example, do not place the monitor inside a car trunk.  
• Unplug the monitor when it is going to be left unused for an extended period of  
time.  
To avoid electric shock, do not attempt to remove any cover or touch the inside  
of the monitor.

Plug-and-Play  
You can install the monitor in any Plug-and-Play-compatible system. The monitor  
automatically provides the computer system with its extended display identification  
data (EDID) using display data channel (DDC) protocols so the computer can configure  
itself and optimize the monitor settings. Most monitor installations are automatic;  
you can select different settings if desired. For more information about changing the  
monitor settings, see Operating the monitor.  
LCD monitor quality and pixel policy  
During the LCD monitor manufacturing process, it is common for one or more pixels  
to become fixed in an unchanging state. This is hard to notice and will not affect the  
display quality or usability. For more information on LCD Monitor Pixel Policy, see:

About your monitor  
Ergonomics  
CAUTION: Improper or prolonged usage of keyboard may result in injury.  
CAUTION: Viewing the monitor screen for extended periods of time may  
result in eye strain.  
For comfort and efficiency, observe the following guidelines when setting up and using  
your computer workstation:  
• Position your computer so that the monitor and keyboard are directly in front of  
you as you work. Special shelves are commercially available to help you correctly  
position your keyboard.  
To reduce the risk of eye strain and neck/arm/back/shoulder pain from using the  
monitor for long periods of time, we suggest you to:  
1. Set the screen about 20 to 28 in. (50-70 cm) from your eyes.  
2. Blink frequently to moisten or rewet your eyes when working with the monitor.  
3. Take regular and frequent breaks for 20 minutes every two hours.  
4. Look away from your monitor and gaze at a distant object at 20 feet away for  
at least 20 seconds during the breaks.  
5. Perform stretches to relieve tension in the neck/arm/back/shoulders during  
the breaks.  
• Make sure that the monitor screen is at eye level or slightly lower when you are  
sitting in front of the monitor.  
• Adjust the tilt of the monitor, its contrast, and brightness settings.  
• Adjust the ambient lighting around you (such as overhead lights, desk lamps, and  
the curtains or blinds on nearby windows) to minimize reflections and glare on the  
monitor screen.  
• Use a chair that provides good lower-back support.  
• Keep your forearms horizontal with your wrists in a neutral, comfortable position  
while using the keyboard or mouse.  
• Always leave space to rest your hands while using the keyboard or mouse.  
• Let your upper arms rest naturally on both sides.  
• Ensure that your feet are resting flat on the floor.  
• When sitting, make sure that the weight of your legs is on your feet and not  
on the front portion of your seat. Adjust your chair’s height or use a footrest if  
necessary to maintain a proper posture.  
• Vary your work activities. Try to organize your work so that you do not have to sit  
and work for extended periods of time. Try to stand or get up and walk around at  
regular intervals.

• Keep the area under your desk clear of obstructions and cables or power cords  
that may interfere with comfortable seating or present a potential trip hazard.

Handling and moving your display  
To ensure the monitor is handled safely when lifting or moving it, follow the guidelines  
mentioned below:  
• Before moving or lifting the monitor, turn off your computer and the monitor.  
• Disconnect all cables from the monitor.  
• Place the monitor in the original box with the original packing materials.  
• Hold the bottom edge and the side of the monitor firmly without applying  
excessive pressure when lifting or moving the monitor.  
• When lifting or moving the monitor, ensure the screen is facing away from you  
and do not press on the display area to avoid any scratches or damage.  
• When transporting the monitor, avoid any sudden shock or vibration to it.

• When lifting or moving the monitor, do not turn the monitor upside down while  
holding the stand base or stand riser. This may result in accidental damage to the  
monitor or cause personal injury.  
Maintenance guidelines  
Cleaning your monitor  
WARNING: Before cleaning the monitor, unplug the monitor power cable  
from the electrical outlet to avoid damage to hardware, property as well as  
personal injury.  
CAUTION: Read and follow the Safety instructions before cleaning the  
monitor.  
For best practices, follow these instructions in the list below while unpacking, cleaning,  
or handling your monitor:  
• If you notice white powder when you unpack your monitor, wipe it off with a  
cloth.  
• Handle your monitor with care as a darker-colored monitor may get scratched  
and show white scuff marks more than a lighter-colored monitor.  
To clean your anti-static screen, lightly dampen a soft, clean cloth with water. If  
possible, use a special screen-cleaning tissue or solution suitable for the anti-  
static coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or  
compressed air.  
• Use a lightly-dampened, soft cloth to clean the monitor. Avoid using detergent of  
any kind as some detergents leave a milky film on the monitor.  
To help maintain the best image quality on your monitor, use a dynamically  
changing screen saver and turn off your monitor when not in use.
