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 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 LCD Monitor Pixel Policy, see
Dell support site at: http://www.dell.com/support/monitors.

from the factory.
NOTE: The arm installing instruction is applicable to the arm shipped with the
monitor. For other mounting solutions (optional), please refer to their respective set
up instructions.
Installing the Arm Base
There are a few types of table configurations which the arm base could be installed:
A. Table with open edge
B. Table with partition with gap between
C. Table with grommet hole
D. Others
A. Table with open edge
• Install the 2 screws either on top row or the
bottom row of arm base bracket depending
on the table thickness.
22 | Setting Up the Monitor
• Insert the clamp bracket key holes to the
screws and slide down to secure in place.
Page 23
• Slide the arm base assembly completely
into the table.
• Tighten the thumbscrew until the clamp
disc is fully in contact with the underside of
table.
B. Table with partition with gap between
• Insert the arm base bracket through the gap
between table and partition.
Setting Up the Monitor | 23
Page 24
• Install the 2 screws either on top row or the
bottom row of arm base bracket depending
on the table thickness.
• Insert the clamp bracket key holes to the
screws and slide down to secure in place.
24 | Setting Up the Monitor
• Tighten the thumbscrew until the clamp
disc is fully in contact with the underside of

Page 26
• Tighten the thumbscrew until the clamp
disc is fully in contact with the underside of
table.
D. Others
Some office partition systems have a swing-open panel for cable management. In
certain cases, the swing-open panel might cause obstruction to the arm base
installation as illustrated below.
A. Without opening the panel, the gap is too small to insert the arm base bracket.
B. The panel need to be opened first before inserting the arm base bracket into the
gap.
C. However, the height of the arm base pole obstructs the panel from closing back.
26 | Setting Up the Monitor
Page 27
The recommended arm base installation steps to overcome this issue:
A. Remove the pole from the arm base by removing the center screw.
B. Open the panel and insert the arm base bracket through the gap.
C. Close the panel and install back the pole to the arm base bracket.
Setting Up the Monitor | 27

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 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.
