Overview
Dell Display Manager(DDM) is an application that allows users to configure their
supported Dell monitor settings such as brightness, contrast, and preset modes.
After its installation, DDM is accessible from the notification tray. Information about
monitors connected to the system is available when the mouse is hovered over the
notification-tray icon.

CI) channel to communicate with your monitor. Ensure that DDC/CI is
enabled in the menu as shown in the following image:

Assigning preset modes to applications | 9
Assigning preset modes to applications
The Auto Mode tab enables you to associate a Preset Mode with a specific
application, and apply it automatically. When Auto Mode is enabled, DDM 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
other.
DDM is preconfigured for many popular applications. To add a new application to the
Application list, simply drag the application from the desktop, Windows Start menu
or elsewhere, and drop it onto the current list.
NOTE: Preset Mode assignments are not supported for batch les,
scripts, loaders, and non-executable les such as zip archives or packed
les.
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
On supported Dell monitors, the Easy Arrange tab enables you to easily arrange
the open windows in one of the predefined layouts by dragging them into the 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.
To get started with Easy Arrange, choose a target monitor and select one of
the predefined layouts. The regions for that layout are displayed momentarily on
the monitor. Next, drag an open window across the monitor. While the window is
being dragged, the current window layout is displayed and an active region gets
highlighted as the window passes over it. At any time, drop the window into the
active region to place the window in that region.
To create a custom window layout, set the size and position the windows on the
desktop and then click the Save link in Easy Arrange. The size and position of the
windows are saved as a custom layout, and the custom layout icon is created.
NOTE: This option does not save or remember the applications that are
open. Only the size and position of the windows are saved.
