Before You Buy

I just updated to macOS Catalina (10.15) and my Displays stopped working. How do I fix this issue?

Computers running macOS Catalina (10.15) may experience compatibility issues with products that use DisplayLink technology, such as USB Docking Stations and Video Adapters. Connecting to a DisplayLink-powered Product may cause the Display(s) to output a blank screen. If you experience this problem, follow these steps:

  1. Update computer to the latest version of macOS 10.15
  2. Permit Screen Recording by following these steps: macOS Catalina 10.15: Screen Recording permission (external link)
  3. Enable the DisplayLink Kernel Extension by following these steps: macOS 10.13, 10.14 and 10.15: Video functionality not enabled (external link)
  4. If the problem persists, try installing the DisplayLink Manager Application (external link). Be sure to run the application after installation and select “Launch automatically after logging-in” for it to start automatically every time you log-in.
