Same here, with MacBook Pro M2 - Sequioa 15.0.1. Suddenly the dock station has stopped seing 2 out of 3 screens connected via DP port to my UD-ULTC4K

Hi there,

Thank you for contacting Plugable! I’m sorry to hear the UD-ULTC4K isn’t working as expected, and I’ll be happy to help.

The most common reason a DisplayLink-based product like UD-ULTC4K may stop outputting video after rebooting or updating macOS is that the DisplayLink Manager is no longer running. The DisplayLink Manager is the software responsible for allowing DisplayLink-based video ports to output to connected displays. If the DisplayLink Manager is not running then the video will not work correctly.

You can see that the DisplayLink Manager is running by checking if its icon is present in the macOS menu bar at the top of your screen. When the icon isn’t present the DisplayLink Manager is not running.

If the DisplayLink Manager isn’t running, you can start it by following these steps:

  1. Open Finder
  2. Navigate to the Applications folder on the left side of the Finder window
  3. Within the Applications folder, locate the DisplayLink Manager
  4. Double-click on the icon for DisplayLink Manager to open it
  5. Verify that the DisplayLink Manager icon appears in the macOS menu bar, indicating it’s running

In case these steps do not help, our next step is to get some additional information.

Can you please send an email to our direct support email address (support@plugable.com) with “For ticket # 499927” in the subject line? In the email, please include the following information:

  1. The Amazon Order ID number for your docking station purchase
  2. While the docking station and displays are connected to your Mac (even if not working as expected), the output of our diagnostic utility PlugDebug: https://plugable.com/pages/plugdebug

This information will help us to determine the next steps.
