About Your Monitor
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
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

Maintenance Guidelines
Cleaning Your Monitor
WARNING: Before cleaning the monitor, unplug the monitor power cable from
the electrical outlet.
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.
