When My DisplayLink-Based Product Is Connected to My Mac Running macOS 12 Monterey, I Do Not See ‘Notifications’ From the Operating System. When I Disconnect the DisplayLink-Based Product From My Mac, Notifications Work As Expected. Why Is This?

Plugable has received reports of Notifications not working as expected when a DisplayLink-based product (such as our UD-3900 or UD-6950Z docking stations) is connected to a Mac running macOS 12 Monterey. 

The cause of this behavior is still being investigated, however in our experience making a small change within the ‘Notifications & Focus’ preference settings can help.

To make this change, please follow these steps:

  1. Click on the ‘System Preferences’ icon (looks like a gear) in the macOS Dock at the bottom of your screen
  2. Click on the ‘Notifications and Focus’ application
  3. At the bottom of the ‘Notifications and Focus’ application window, click to place a checkmark in the ‘When mirroring or sharing the display’ option under the ‘Allow notifications’ section.  An example screenshot with this option highlighted is included below:
