Figure 19: Multiple Displays
Figure 20: Single Display (PBP on)
Figure 21: Single Display (PBP off)
Note:
- Availability of Network KVM features depends on the network policy set out by the company or IT. This feature requires opening the access control list (ACL) for network incoming and outgoing traffic control.
- Network KVM is modular (optional to install). It does not install by default, and users can choose not to install it while downloading the software and use other features of Dell Display Manager. If users want to install Network KVM later, it requires fresh installation of version 2.3 and above.
- You may experience delayed response from remote computers on Network KVM due to network latency limitations.
- Certain key combinations, function keys, specialized keys, and touch bar keys are not supported for controlling remote computers. While clipboard sharing in a cluster, Cut and Paste is not supported on remote computers.
- The established Cluster may not resume connection after Network KVM is turned back on from the off state, after the main computer is woken 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 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 recommended to install anti-malware or other security tools before using File and Content Transfer in Network KVM. If you prefer not to share files between computers, you can go to KVM Settings and use Manage Cluster to turn off this feature.
- If your cluster has Windows and Mac devices, connect keyboard and mouse to Mac if possible, as remote Mac device cannot be accessed.
- It is not recommended to turn on both-Apple Universal Control and Network KVM as it might cause confusion.

Remote Firmware Update for Dell Display Manager
Pre-Requisites for carrying out a Firmware Update
Connect a USB Type-C or USB upstream cable between the monitor and your computer. (Preferably a direct connection between your computer and the monitor.) You can connect the computer with monitor 1 and then USB cables between the monitors with Multi-Stream Transport (MST) turned on for multiple monitors.
See the setup configurations below:
NOTE: Monitor 1 and Monitor 2 can be identical or different models.
Configuration A (The computer is connected to monitor 1 and monitor 1 is daisy-chained using a USB connection to monitor 2.)
- A USB A to B cable between the monitor to the computer is mandatory to allow the firmware update (Shown in Red.)
- A USB A to B cable is required between the computer and Monitor 1 if the computer is connected with monitor 1 using either a DP or mDP cable. (Shown in Red.)
Figure 41 Configuration A
Configuration B (The computer is directly connected to monitor 1 and monitor 2).
- A DP, mDP, or HDMI cable is used between the computer and Monitor 1. The computer must also connect with monitor 1 and monitor 2 using a USB upstream cable.
- A USB C or Thunderbolt cable between monitor 1 and monitor 2 does not require any other cables to be used.
Figure 42 Configuration B
Firmware mass deployment for your monitors using command-line commands in the Windows Operating System
There are two methods that allow you to deploy firmware (FW) updates remotely:
-
Deploy the firmware update through either Microsoft EndPoint Manager, SCCM, or Intune using PowerShell scripts (See the summary section for more details.)
-
Send a command to update the firmware using the Dell Display Manager Command Line: (
ddm.exe /fwupdate deferorddm.exe /fwupdate force)
NOTE: DDM is disabled while a firmware update is in progress. The update can take between 15 to 30 minutes depending on the complexity of the monitor models. At the end of the update, the monitor must restart automatically and it blanks momentarily.
Here are the commands to perform software and firmware updates:
| Command | Description |
|---|---|
LiveUpdate |
Issue this command to update the software silently if an update is available. The installation requires admin rights, and the update only happens after the monitor is connected.
|
NoUpdate [on/off] |
Turn On, Off, SW, FW, or the Auto Update Notification. By default, DDM sends a notification to you to inform you of the SW or FW update when they are available.
|
LockUpdate |
Disable the SW and FW update on the UI so that the IT admin centrally manages the updates. Once it is disabled, IT admin must use
|
Here are the various windows notifications that inform you on the progress and update status:
| Condition | Message | Example |
|---|---|---|
| FW is available update. | An update is available for <monitor model>. Update your monitor by connecting the monitor directly to the computer using a USB cable. <Right Now> <Reminder Later> | Defer Force  |
| FW is updating. | Updating the firmware for <monitor model>. The application resumes after completion. |  |
| FW is updated successfully. | Updated the firmware for the <monitor model>_<service tag> successfully |  |
| FW is unable to update successfully. | Failed to update the firmware for <monitor model>_<Service Tag>. |  |
The Command-Line commands to update the firmware are:
|
|
This mode allows you to defer the firmware update and update now. You can defer the firmware update so that they do not disrupt the current activities. You are reminded the next day when the monitor is connected again. |
|
|
This mode allows you to update the firmware immediately. You are informed of the activities before the firmware updates. |
