Power management modes

If you have a VESA DPM™ compliant display

card or software installed on your

computer, 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 to function. The following table shows the power consumption and
signaling of this automatic power saving feature:

Plug and Play capability

You can connect the monitor to 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 that
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.

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

www.dell.com/support/monitors.

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:

• 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, 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 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.

time, we suggest you to:

1. Set the distance of the screen between 20 inches to 28
inches (50 - 70 cm) from your eyes.

2. Blink frequently to moisten your eyes or wet your eyes
with water after prolonged usage of the monitor.

3. Take regular and frequent breaks for 20 minutes every
two hours.

4. Look away from your monitor and gaze at a distant
object at 20 feet away for at least 20 seconds during
the breaks.

5. Perform stretches to relieve tension in the neck, arm,
back, and shoulders during the breaks.
