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, or shoulder pain from using the monitor for long period, we recommend you to:

1. Set the distance of the screen between 20 in. to 28 in. (50 cm - 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.

24 │ About your monitor

• 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.

• 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 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.

monitor.

WARNING: Before cleaning the monitor, unplug the monitor power

cable from the electrical outlet.

For best practices, follow the instructions in the list below when unpacking, cleaning, or handling your monitor:

• To clean the Dell monitor screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the Dell monitor screen.

CAUTION: Do not use detergents or other chemicals such as benzene,

thinner, ammonia, abrasive cleaners, or compressed air.

CAUTION: Using chemicals for cleaning may cause changes in the

appearance of the monitor, such as color fading, milky film on the monitor, deformation, uneven dark shade, and peeling of screen area.

Troubleshooting

WARNING: Before you begin any of the procedures in this section,

follow the Safety instructions.

Self-Test

Your monitor provides a self-test feature that allows you to check if your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and the monitor.

2. Disconnect all video cables from the monitor. This way, the computer doesn’t

have to be involved.

3. Turn on the monitor.

The floating dialog box should appear on-screen (against a black background), if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains white. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

No HDMI Cable

The display will go into Standby mode in 4 minutes.
