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

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

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 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.
