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.

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 P2X23D
To create a custom window layout, size and position the windows 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.

To use the custom layout, select the custom layout icon. To delete the currently
saved custom layout, close all windows on the desktop and then click the Save link

Managing Multiple Video Inputs
The Input Manager tab enables you to manage multiple video inputs connected
to your Dell monitor. It makes it very easy to switch between inputs while you work
with multiple computers.
All video input ports available to your monitor are listed. You can give each input a
name as you like. Please save your changes after editing.
You can define a shortcut key to quickly switch to your favorite input and another
shortcut key to quickly switch between two inputs if you often work between them.
Dell P2X23D
NOTE: Dell Display Manager (DDM) communicates with your monitor
even when the monitor is displaying video from another computer. You
can install Dell Display Manager on the computer you frequently use
and control input switching from it. You may also install Dell Display
Manager on other computers connected to the monitor.

Restoring Application Positions
Dell Display Manager can help you restore application windows into their positions
when you reconnect your computer to the monitor(s). You can quickly access this
feature by right-clicking on Dell Display Manager icon in the notification tray.
If you choose “Auto-restore window layout”, your application windows’ positions
are tracked and remembered by Dell Display Manager. Dell Display Manager
automatically puts the application windows into their original positions when you
reconnect your computer to your monitor(s).
14 | Restoring Application Positions
If you want to go back to a favorite layout after you have moved the application
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. Dell Display Manager 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.
NOTE: You should keep your applications running in order to benefit
from this feature. Dell Display Manager does not launch applications.

Troubleshooting
DDM only works with supported Dell monitors. DDM does not support monitors
from other manufacturers. If DDM cannot work with your monitor, DDM will show
the following icon in your notification tray.
10:17 AM
2021/11/1
When the icon is clicked, DDM shows a more detailed error message.
If DDM is unable to detect and/or communicate with a supported Dell monitor, try
the following troubleshooting steps:
1. Ensure the video cable is properly connected to your monitor and your
computer. The connectors should be firmly inserted into position.
2. Check the monitor OSD to ensure DDC/CI is enabled.
3. Ensure you have the correct and latest graphics-card driver from your graphic-
card manufacturer such as Intel, AMD, and NVIDIA. Incompatible or old version
of graphics-card driver causes DDM to fail.
Troubleshooting | 19
4. Remove any docking stations or cable extenders or converters between the
monitor and the graphics port. Some low-cost extenders, hubs or converters
may not support DDC/CI properly and may cause the DDM application to fail.
Update the driver of such device if the latest version is available.
5. Restart your computer.
DDM may not work on the following monitors:
• Dell monitor models from 2013 or earlier and D-series of Dell monitors. You can
refer to Dell Product Support websites for more information.
• Gaming monitors using Nvidia-based G-sync technology.
• Virtual and wireless displays do not support DDC/CI.
• On older models of monitors with DisplayPort version 1.2, you may need to
disable MST/DP 1.2 using the OSD menu on the monitor.
If your computer is connected to the Internet, you will be prompted with a message
when a newer version of DDM application is available. It is recommended to
download and install the latest DDM application.
You may also check for new version by right-clicking on DDM icon while pressing
and holding the Shift key.
