Assigning Preset Modes To Applications | 9

Assigning Preset Modes To Applications

The Auto Mode tab enables 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 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

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 in 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.

Dell P2421DC

To create a custom window layout, size and position the windows (maximum 10) on

the desktop and then click the Save link in Easy Arrange. The size and position of

the windows is 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 is saved.
