Dell Display Manager User's Guide
Overview
Dell Display Manager is a Windows application used to manage a monitor
or a group of monitors. It allows manual adjustment of the displayed
image, assignment of automatic settings, energy management, image
rotation and other features on select Dell models. Once installed, Dell
Display Manager will run each time the system starts and will place its
icon in the notification tray. Information about monitors connected to the
system is always available when hovering over the notification tray icon.
Using the Quick Settings Dialog
Clicking Dell Display Manager’s notification tray icon opens the Quick
Settings dialog box. When more than one supported Dell model is
connected to the system, a specific target monitor can be selected using
the menu provided. The Quick Settings dialog box allows convenient
adjustment of the monitor’s Brightness and Contrast levels, Preset Modes
can be manually selected or set to Auto Mode, and the screen resolution
can be changed.
6  Dell Display Manager User's Guide
The Quick Settings dialog box also provides access to Dell Display
Manager’s advanced user interface which is used to adjust Basic
functions, configure Auto Mode and access other features.
Setting Basic Display Functions
A Preset Mode for the selected monitor can be manually applied using
the menu on the Basic tab. Alternatively, Auto Mode can be enabled. Auto
Mode causes your preferred Preset Mode to be applied automatically
when specific applications are active. An onscreen message momentarily
displays the current Preset Mode whenever it changes.
The selected monitor’s Brightness and Contrast can also be directly
adjusted from the Basic tab.
Dell Display Manager User's Guide  7
Assigning Preset Modes to Applications
The Auto Mode tab allows you to associate a specific Preset Mode
with a specific application, and apply it automatically. When Auto
Mode is enabled, Dell Display Manager will automatically switch to the
corresponding Preset Mode whenever the associated application is
activated. The Preset Mode assigned to a particular application may be
the same on each connected monitor, or it can vary from one monitor to
the next.
Dell Display Manager is pre-configured for many popular applications. To
add a new application to the assignment list, simply drag the application
from the desktop, Windows Start Menu or elsewhere, and drop it onto the
current list.
NOTE: Preset Mode assignments targeting batch files, scripts, and
loaders, as well as non-executable files such as zip archives or packed
files, are not supported and will be ineffective.
8  Dell Display Manager User's Guide
Applying Energy-Conservation Features
On supported Dell models, the PowerNap tab will be available to provide
energy conservation options. When the screensaver activates, the
monitor’s Brightness can automatically be set to minimum level or the
monitor can be put to sleep in order to save additional power.

Monitor Specifications
The following sections give you information about the various power
management modes and pin assignments for the various connectors of
your monitor.
Power Management Modes

when not in use. This is referred to as Power Save Mode. If the computer
detects input from 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:

LCD Monitor Quality & Pixel Policy
During the LCD Monitor manufacturing process, it is not uncommon for
one or more pixels to become fixed in an unchanging state. The visible
result is a fixed pixel that appears as an extremely tiny dark or bright
discolored spot. When the pixel remains permanently lit, it is known as a
“bright dot.” When the pixel remains black, it is known as a “dark dot.”
In almost every case, these fixed pixels are hard to see and do not
detract from display quality or usability. A display with 1 to 5 fixed pixels
is considered normal and within competitive standards. For more
information, see Dell Support site at:
http://www.dell.com/support/monitors.

Maintenance Guidelines
Caring for Your Monitor
CAUTION: Read and follow the safety instructions before cleaning
the monitor.
CAUTION: 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, slightly 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 slightly dampened, warm cloth to clean the plastics. Avoid using
detergent of any kind as some detergents leave a milky film on the
plastics.
• If you notice a white powder when you unpack your monitor, wipe it
off with a cloth. This white powder occurs during the shipping of the
monitor.
• 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 power off your monitor when
not in use.

Troubleshooting
WARNING: Before you begin any of the procedures in this section,
follow the Safety Instructions
Self-Test
Your monitor provides a self-test feature that allows you to check
whether your monitor is functioning properly. If your monitor and
computer are properly connected but the monitor screen remains dark,
run the monitor self-test by performing the following steps:
1. Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure
proper Self-Test operation, remove all video cables from the back of
computer.
2. Turn on the monitor.
The floating dialog box should appear on-screen (against a black
background) if the monitor cannot sense a video signal and is working
correctly. While in self-test mode, the power LED remains white. Also,
depending upon the selected input, one of the dialogs shown below
will continuously scroll through the screen.
3. This box also appears during normal system operation, if the video
cable becomes disconnected or damaged. The monitor will enter
Power Save Mode after 5 minutes if left at this state.
4. Turn off your monitor and reconnect the video cable; then turn on
both your computer and the monitor.
If your monitor screen remains blank after you use the previous
procedure, check your video controller and computer, because your
monitor is functioning properly.
Troubleshooting  55
Built-in Diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the
screen abnormality you are experiencing is an inherent problem with your
monitor, or with your computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable
is unplugged and the monitor is in self-test mode.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of
the screen).
2. Unplug the video cable(s) from the back of the computer or
monitor. The monitor then goes into the self-test mode.
3. Press and hold the Button 1 and Button 4 on the front panel
simultaneously for 2 seconds. A gray screen appears.
4. Carefully inspect the screen for abnormalities.
5. Press the Button 4 on the front panel again. The color of the screen
changes to red.
6. Inspect the display for any abnormalities.
7.Repeat steps 5 and 6 to inspect the display in green, blue, black,
white and text screens.
The test is complete when the white screen appears. To exit, press the
Button 4 again.
If you do not detect any screen abnormalities upon using the built-in
diagnostic tool, the monitor is functioning properly. Check the video card
and computer.
