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 the Monitor.
Universal Serial Bus (USB) Interface
This section gives you information about the USB ports that are available on the left side of 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: support.dell.com.
Maintenance Guidelines
Cleaning Your 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 while unpacking, cleaning, or handling your monitor:
To clean your antistatic screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the antistatic coating. Do
not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
Use a lightly-dampened, warm 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 scratch 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.
