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.

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.

windows around, you can first “Save current window layout” and later “Restore
saved window layout”.

You may use monitors with different models or resolutions in your daily routine,
and you may apply different window layouts on them. DDM is able to know the
monitor you have reconnected and restore application positions accordingly. In case
you need to replace a monitor in a monitor matrix configuration, you can save the
window layout before replacement and restore the layout after a new monitor is
installed.

from this feature. DDM does not launch applications.

Please note that DDM only works with Dell branded monitors. If you are using
monitors from other manufacturers, DDM doesn’t support them.
If DDM is unable to detect and/or communicate with a supported Dell monitor,
please take below actions to troubleshoot:
1. Make sure the video cable is properly connected to your monitor andyour PC,
especially the connectors should be firmly inserted into position.
2. Check the monitor OSD to ensure DDC/CI is enabled.
3. Make sure you have the correct and latest display driver from the graphics
vendor (Intel, AMD, NVidia, etc.). Display driver is often the cause of DDM failure.
