About your monitor
Plug-and-Play
You can connect the monitor to any Plug-and-Play compatible computer. The monitor automatically provides the computer with its
Extended Display Identification Data (EDID) using Display Data Channel (DDC) protocols so that the computer can configure itself
and optimize the monitor settings. Most monitor installations are automatic; you can select different settings as required. 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 not uncommon for one or more pixels to become fixed in an unchanging state
which are hard to see and do not affect the display quality or usability. For more information on Dell Monitor Quality and Pixel Policy,
see Dell Display Pixel Guidelines.
Ergonomics
CAUTION: Improper or prolonged usage of a 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 or shoulder pain from using the monitor for long periods of time, it is
recommended that you:
1. Set the distance of the screen between 20 in. to 28 in. (50 cm to 70 cm) from your eyes.
2. Blink frequently to moisten your eyes or wet your eyes with water after prolonged usage of 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, arms, back and shoulders during the breaks.
• Ensure 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 of the chair.
• Ensure that your feet are resting flat on the floor.
• When sitting, ensure that the weight of your legs is on your feet and not on the front portion of your seat. Adjust the height of
your chair 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 cables that may interfere with comfortable seating or
present a potential trip hazard.
