What is Login Screen Extension

When a Mac first boots and presents a login screen, the DisplayLink Manager Application is NOT running. As a result, any DisplayLink display will not work.

Only after the user logs in to the system will the DisplayLink display work.

Thank you for your answer.
Nevertheless, in spite of your explanation I still can't get DisplayLink display to work without adding the Login Screen Extension.

In details (the computer is a laptop, MacBook pro, and I only installed the DisplayLink Manager)

1- I reboot the laptop
2- my laptop is in use, and my personal session opened (so I'm not in the login screen, but in my session, with the Mac Desktop opened)
3- then I go to a room with a DisplayLink display
4- I manually launch the application "DisplayLink Manager"
5- a menubar item appears, and in this menubar item I see always see the message stated above:
"No Displaylink-enabled display connected"

Only if I add the Login Item Extension (and redo the whole scenario above) will the external DisplayLink display be detected.

So I must miss something, but I don't know where...
Regards,
