Must Know for macOS User: https://support.displaylink.com/knowledgebase/articles/1916602-macos-catalina-10-15-screen-recording-permission

1> macOS Catalina 10.15 requires the user to permit "Screen Recording" in order for DisplayLink devices to work properly. The message is generated by the OS and the screen is not actually being recorded by DisplayLink. Approving it enables the DisplayLink driver to access the pixels it needs to render a mirrored or extended screens, and send the pixels over USB from your computer to the DisplayLink display. It does not send any data or pixels back to DisplayLink.

2> To approve the permission, please follow these steps: Apple Menu-->System Preference--> Security&Privacy->select "Privacy" tab->Scoll to find" Screen Recording" and check "DisplayLink Driver"

3> Since the screen is recording, you cannot watch any HDCP content(Netflix/Prime/ iTunes/Hulu...), the screen will be black.
