Safety instructions
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.
∞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.

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/support/
monitors
