Overview
Dell Display Manager is a Microsoft Windows application used to manage a monitor or
a group of monitors. It allows manual adjustment of the displayed image, assignment
of automatic settings, energy management, window organization, image rotation,
and other features on selected Dell monitors. After installed, Dell Display Manager
runs each time when the system starts and places its icon in the notification tray.
Information about monitors connected to the system is available when hovering over
the notification-tray icon.

box. When more than one supported Dell monitors are connected to the computer, a
specific target monitor can be selected using the menu. The Quick Settings dialog
box allows you to easily adjust the brightness, contrast, resolution, window layout, and
so on. It also allows you to enable automatic switching between preset modes or to
select a preset mode manually.

Assigning Preset Modes to Applications
The Auto Mode tab allows you to associate a specific Preset Mode with a specific
application, and apply it automatically. When Auto Mode is enabled, Dell Display
Manager automatically switches 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 another.
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 files, scripts, loaders, and non-
executable files such as zip archives or packed files, 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
Easy Arrange helps you to effectively organize your application windows on the
desktop. You first choose a pre-defined layout pattern which suits your work, then
you just need to drag the application windows into the defined 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.
For Windows 10, you can apply different window layouts for each of the virtual
desktops.
If you often use Windows snap feature, you can select “Hold down the SHIFT key to
enable zone positioning”. This gives Windows snap priority over Easy Arrange. You
will then need to press the Shift key to use Easy Arrange positioning.

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

Restoring Application Positions
DDM can help you restore application windows into their positions when you reconnect
your computer to the monitor(s). You can quickly access to this feature by right-
clicking on DDM icon in the notification tray.
If you choose “Auto-restore window layout”, your application windows’ positions are
tracked and remembered by DDM. DDM automatically puts the application windows
into their original positions when you reconnect your computer to your monitor(s).
To go back to a favorite layout first, select “Save current window layout” and then
“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 display is
installed.
NOTE: You should keep your applications running in order to benefit from
this feature. DDM doesn’t launch applications.

Troubleshooting
If DDM does not work with your monitor, DDM will show the following icon in your
notification tray.
Click on the icon, DDM shows a more detailed error message.
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 the following actions to troubleshoot:
1. Make sure the video cable is properly connected to your monitor and your
computer. 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 Graphics driver from the graphics
vendor (Intel, AMD, NVidia, etc.). Graphics driver is often the cause of DDM
failure.
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 can fail DDM. Update the driver of such
device if the latest version is available.
5. Restart your computer.

Troubleshooting
DDM may not work with the following monitors::
• Dell monitor models earlier than year 2013 and D-series of Dell monitors. For
more information see www.dell.com/support/monitors.
• Gaming monitors using Nvidia-based G-sync technology
• Virtual and wireless monitors do not support DDC/CI
• Some early models of DP 1.2 monitors, it may be necessary to disable MST/DP
1.2 using the display OSD
If your PC is connected to the Internet, you will be prompted to upgrade to a newer
version of DDM when it 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.
