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.
