How to change main display to another monitor

First i install my mac mini using lcd projector, it became default display. After i've got my Lenovo G27-20 monitor, i want to make it as my main display, but i couldn't do that. I just can make it as extended or mirror display. Everytime,I need to connect mac mini hdmi to my projector (although it turned off) to make my G27-20 works.

Is there any way to make my G27-20 working independently.

Mac mini, macOS 12.1

In your first screenshot drag the Menu bar to the display that you want as the main display. It that does not help, click on the arrows next to the where it says Main display and reverse the Main and Extended displays.
