Power management modes

If you have VESA’s DPM-compliant video card or software installed in your PC, the
monitor can automatically reduce its power consumption when not in use. This is
referred to as power save mode*. If the computer detects input from the keyboard,
mouse, or other input devices, the monitor automatically resumes functioning. The
following table shows the power consumption and signaling of this automatic power
saving feature.

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 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 LCD Monitor 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 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.

20 | About your monitor

• 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.

22 | About your monitor

• 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.

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:

• 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.

• 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 help maintain the best image quality on your monitor, use a dynamically
changing screen saver and turn off your monitor when not in use.

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 whether 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 o both your computer and the monitor.

2. Unplug the video cable from the back of the computer. To ensure proper Self-

Test operation, remove all digital and the analog cables from the back of

computer.

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.

then goes into the self-test mode.

3. Press and hold Button 5 for 4 seconds, system will pop OSD message, select
and press Button 1. A gray screen appears.

4. Carefully inspect the screen for abnormalities.
