20 About your monitor

Plug and play capability
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 system 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 your 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 Support site at www.dell.com/pixelguidelines.

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 distance of the screen between 20 to 28 in. (50 – 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, arm, back, and 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.
22 About your monitor

· 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.
