16 │About your monitor
Plug and play capability
You can connect the monitor to 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 that 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 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 about Dell Monitor Quality and Pixel Policy, see Dell Support
site at www.dell.com/pixelguidelines.
Maintenance guidelines
Cleaning your monitor
CAUTION: Read and follow the Safety instructions before cleaning the
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:
• Use a clean cloth that is slightly dampened with water to clean the stand assembly, the
screen, and the chassis of your Dell monitor. If available, use a screen-cleaning tissue or
solution suitable for cleaning Dell monitors.
• After cleaning the surface of the table, ensure that it is thoroughly dry and free from any
moisture or cleaning agent before placing your Dell monitor on it.
CAUTION: Do not use detergents or other chemicals such as benzene, thinner,
ammonia, abrasive cleaners, alcohol, 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.

About your monitor │17
WARNING: Do not spray the cleaning solution or even water directly on the
surface of the monitor. Doing so will allow liquids to accumulate at the bottom
of the display panel and corrode the electronics resulting in permanent
damage. Instead, apply the cleaning solution or water to a soft cloth and then
clean the monitor.
NOTE: Monitor damage due to improper cleaning methods and the use of
benzene, thinner, ammonia, abrasive cleaners, alcohol, compressed air,
detergent of any kind will lead to a Customer Induced Damage (CID). CID is
not covered under the standard Dell warranty.
• If you notice white residual 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.
