macOS requires the user to permit "Screen Recording" for DisplayLink driver to work properly. Approving it enables the DisplayLink to access the pixels it needs to render a mirrored or extended screen and send the pixels over USB from your computer to the DisplayLink display. It does not send any data or pixels back to DisplayLink.

User is notified about a need for Screen Recording permission in three places.

- By macOS dialog box on first DisplayLink device plug-in

- By DisplayLink driver on each device plug-in:

- By DisplayLink Manager app warning in macOS status bar: 

To approve the permission, please follow these steps:

1. Open System Settings

2. Go to Privacy & Security > Screen Recording

3.   From Screen Recording tab toggle DisplayLink Manager

4.   Authenticate the changes by using your login details

5.   Click “Quit & Reopen”
