Safety instructions
Use the following safety guidelines to protect your monitor from potential damage
and to ensure your personal safety. Unless otherwise noted, each procedure
included in this document assumes that you have read the safety information that
shipped with your monitor.
Before using the monitor, read the safety information that is
shipped with your monitor and also printed on the product. Keep the
documentation at a secure location for future reference.
CAUTION: 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.
• Place the monitor on a solid surface and handle it carefully. The screen is fragile
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.
• Connect the power cable from the monitor to a wall outlet that is near and
accessible. See Connecting your monitor.
• Do not place and use the monitor on a wet surface or near water.
• 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.

Power management modes
If you have VESA's DPM compliance display card or software installed in your PC,
the monitor can automatically reduce its power consumption when not in use. This
is referred to as Standby 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.
* Zero power consumption in Off Mode can only be achieved by disconnecting the
power cable from the 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.

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.
If the monitor is working correctly, it detects that there is no signal and one of the
following message appears. While in self-test mode, the power LED remains white.
