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.

NOTE: DDM uses Display Data Channel Command Interface (DDC/

CI) channel to communicate with your monitor. Ensure that DDC/CI is

enabled in the menu as shown in the following image:

You can select Manual Mode to manually select a preset mode or select Auto

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.
