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 selected Dell monitors. After 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 | 5
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.

You can select Manual Mode that enables you to manually select a preset mode or

matrix control” to apply brightness, contrast and color presets controls to
all monitors.

Assigning Preset Modes to Applications | 9
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 les, scripts, loaders, and non-
executable les such as zip archives or packed les, 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.
10 | Organizing Windows with Easy Arrange
Organizing Windows with Easy Arrange
Easy Arrange helps you to effectively organize your application windows on the
desktop. You first choose a pre-defined layout pattern which suits your work, then
you just need to drag the application windows into the defined zones. Press “>” or use
Page Up/Page Down key to find more layouts. To create a custom layout, arrange the
open windows and then click Save.
For Windows 10, you can apply different window layouts for each of the virtual
desktops.
If you often use Windows snap feature, you can select “Hold down the SHIFT key to
enable zone positioning”. This gives Windows snap priority over Easy Arrange. You
will then need to press the Shift key to use Easy Arrange positioning.
