Dell Display Manager User's Guide

Overview

Dell Display Manager is a Microsoft 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, window organization, image rotation, and
other features on select Dell monitors. Once installed, Dell Display Manager runs each
time the system starts and places its icon in the notification tray. Information about
monitors connected to the system is 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 monitors are connected to the computer, a
specific target monitor can be selected using the menu. The Quick Settings dialog box
allows you to easily adjust the brightness, contrast, resolution, window layout, and so on.
It also allows you to enable automatic switching between preset modes or to select a
preset mode manually.

The Quick Settings dialog box also provides access to Dell Display Manager's advanced
user interface that is used to adjust basic functions, configure auto mode and access
other features.

Setting Basic Display Functions

You can manually select a preset mode or you can select Auto Mode that applies a
preset mode based on the active application. 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.

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 automatically switches 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
another.

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 for batch files, scripts, loaders, and non-

executable files such as zip archives or packed files, are not supported.

You can also configure the Game preset mode to be used whenever a Direct3D
application runs in full-screen mode. To prevent an application from using mode, assign
a different preset mode to it.

Easy Arrange Your Monitor Window Layout

On supported Dell monitors, the Easy Arrange tab allows you to easily arrange the open
windows in one of the predefined layouts by dragging them in the zones. To create a
custom layout, arrange the open windows and then click Save.

Managing Multiple Video Inputs

The Input Manager tab provides convenient ways for you to manage multiple video
inputs connected to your Dell monitor. It makes it very easy to switch between inputs
while you work with multiple computers.

All video input ports available to your monitor are listed. You can give each input a name
as you like. Please save your changes after editing.

You can define a shortcut key to quickly switch to your favorite input and another
shortcut key to quickly switch between two inputs if you often work between them.

You can use the dropdown list to switch to any input source.

NOTE: DDM communicates with your monitor even when the monitor is displaying

video from another computer. You can install DDM on the PC you frequently use
and control input switching from it. You may also install DDM on other PCs
connected to the monitor.

monitor between two computers. You can define a shortcut key to quickly switch the
device between the two computers.

computers.

thumb drive.
