Approving it enables the DisplayLink driver to access the pixels needed to render a mirrored or extended screen, and send
the pixels from your computer to the DisplayLink display over USB.

If you have enabled notifications from DisplayLink Manager, it will remind you to allow screen recording when it detects that this permission is missing.
