Power Management Modes

If you have VESA’s DPM™ compliance display card or software installed in your PC,
the monitor can automatically reduce its power consumption when not in use. This
is referred to as Power Save Mode. If the computer detects input from the
keyboard, mouse, or other input devices, the monitor automatically resumes
functioning. The following table shows the power consumption and signaling of this
automatic power saving feature.

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 Identication
Data (EDID) using Display Data Channel (DDC) protocols so the system can
congure itself and optimize the monitor settings. Most monitor installations are
automatic, you can select dierent settings if desired. For more information about
changing the monitor settings, see Operating your monitor.

LCD monitor quality and pixel policy

During the LCD Monitor manufacturing process, it is normal for one or more pixels
to become xed in an unchanging state which are hard to see and do not aect the
display quality or usability. For more information on Dell Monitor Quality and Pixel
Policy, see Dell Support site at www.dell.com/support/monitors.

Maintenance guidelines

Cleaning your monitor

WARNING: Before cleaning the monitor, unplug the monitor power cable
from the electrical outlet.

CAUTION: Read and follow the Safety Instructions before cleaning the
monitor.

For best practices, follow the instructions in the list below while unpacking, cleaning
or handling your monitor:

To clean your 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 cloth to clean the monitor. Avoid using detergent of any
kind as some detergents leave a milky lm on the monitor.
If you notice white powder when you unpack your monitor, wipe it o 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 o your monitor when not in use.
