How to stop automatic duplicate/extend displays


Hello all! I'm using my Windows 10 laptop with a secondary external monitor which i want to use as a display, without the laptop's built-in display. The problem is, despite i set to show the image only on the secondary (external) monitor, after each restart or after i close the laptop's lid, it reverts to duplicating the image (or extends it, if select extend inside of duplicate). How can i stop this?? I have to manually reselect to show the image on the 2nd display only. Thanks!
