Plug and play capability

You can install the monitor in any Plug and Play-compatible system. The monitor automatically
provides the computer 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 as required.
For more information about changing the monitor settings, see

LCD monitor quality and pixel policy

During the LCD Monitor manufacturing process, it is normal 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 about Dell Monitor Quality and Pixel Policy, see Dell Support site
at www.dell.com/pixelguidelines.

Maintenance guidelines

Cleaning your monitor
WARNING: Before cleaning the monitor, unplug the monitor power cable
from the electrical outlet.
CAUTION: Read and follow the
monitor.
For best practices, follow these instructions in the list below while unpacking, cleaning or
handling your monitor:
• To clean your screen, lightly dampen a soft and 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 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 the black-colored monitor may get scratched.
• 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.
