Overview

Dell Display Manager (DDM) is a Windows application used to manage a monitor or a group of monitors.
DDM allows you to configure the monitor settings, control power settings, organize applications in different screen layouts, and other functions on supported Dell monitors.
After installing DDM, it runs each time you restart your computer. A quick access icon is available in the system taskbar, with information about connected monitors available when you hover your cursor over the DDM icon.

System requirements
DDM supports the following x86-based Windows:

• Windows 10 build 17763 and above
• Windows 11

NOTE: Certain functions are hardware dependent. See your monitor user guide for information about the functions that are available.
NOTE: Screenshots in this document are for illustrative purposes only. Some functions may not be supported by your monitor.

Using the Network KVM
The connected computers act as one Cluster to run KVM functions. Each Cluster may contain up to a maximum of four computers.

connected computers, but only one computer is in control at  any given time.
NOTE: When using a high DPI mouse, you may experience delayed response from remote computers  due to bandwidth limitations.
NOTE: Certain key combinations, function keys, specialized keys, and touch bar keys are not  supported for controlling remote computers.
Mouse crossing| The mouse cursor can cross to other connected computers. The crossing point is determined by KVM  settings.
Clipboard sharing| Allows you to copy clipboard text, image, or files to other connected computers.
NOTE: Cut and Paste is not supported on remote computers.
Drag and drop| Allows you to drag and drop text or files to other connected computers.

CAUTION: Dell Display Manager enables secure content and file sharing between computers with end-to-end encryption.
However, it does not function as anti-malware software, providing no scanning or protection against malicious files during transfers. It is strongly recommended to install anti- malware or other security tools before utilizing File and Content Transfer in Network  KVM. If you prefer not to share files between computers, you can navigate to KVM Settings > Manage Cluster to turn off this feature.

NOTE: You have the option to adjust the mouse crossing point through laptop screen arrangement. If there is a screen positioned between the crossing points in a monitor setup with PBP mode, the mouse might be unable to move to that screen. In such  instances, Network KVM may automatically rearrange your monitor positions.
NOTE: The established Cluster may not resume connection after Network KVM is turned back on from the off state, after the main computer is wake from suspension, or after connecting to a supported monitor. In this case, you may manually switch the cluster  from the drop-down list, or you may manually connect the offline computer from the Network KVM main page.

• Dell monitor models not included in DDM for Windows supported list. For more information, see https://www.dell.com/support/ddm
• Monitors not listed in DDM for Windows support list. Virtual and wireless monitors do not support DDC/CI

Unable to detect supported Dell monitor
In the following scenarios, Dell Display Manager might not be able to communicate with the monitor.

1. The primary monitor has turned on Multi-Monitor Sync (MMS).
2. The monitor is busy with color calibration.
3. The monitor has Screen Partition turned on.
4. DDC/CI is turned off.

If DDM cannot identify or establish communication with a compatible Dell monitor, follow these steps to troubleshoot:

1. Make sure the video cable or USB upstream cable is properly connected to your monitor and your computer. Ensure all the connectors are correctly connected to the ports.
2. Check the monitor OSD to ensure DDC/CI is enabled.

Unable to connect to Network KVM
If you encounter difficulty connecting to a remote computer through Network KVM, follow these troubleshooting steps:

1. Verify the firewall settings and confirm that all Dell Display Manager items are enabled.
2. Ensure that all applications permitted to communicate through Windows Defender Firewall are selected.
3. Reach out to your network administrator and confirm that all network ports (default 5566, 5567, 5568) are open for both inbound and outbound communication.

Network KVM switches to another cluster
Network KVM unexpectedly switches to another cluster during normal use. This is because Network KVM binds the connected monitor to a cluster when:

• user creates a cluster.
• user selects a cluster.

For optimum usage, Network KVM attempts to resume connection with the cluster that has the highest priority. If connection fails, Network KVM goes down in order and attempts to connect with another cluster. When this happens, you can manually select the  cluster you wish to use from the KVM menu.

Compatibility between application installed on your system
DDM is backward compatible with previous version. Recommended to always use the latest DDM version.
