Macbook and external monitor

[sadibe1974]

Hello everyone.
Connected my macbock to an external monitor.
This is set as the main screen and the Macbook as a slave.
Is there a way that the Macbook will automatically take over these settings when it restarts?

Now I always have to go through the control panel and set it up again.

Thank you very much for the help.
