How to keep the display window in the main screen?

I use my laptop (macbook pro) with up to 4 video projectors.
When I launch the display window of Processing, I need to open it only in the screen of my laptop (and not in the screen of another screen or video projectors). Please, how to do it ?
Best regards !

I guess that’s just a setting you have to fix on your mac :
Sytem preferences > Monitors > Display > Mirror displays to check/uncheck if I remember well

I think you can also move displays to reorder as you want, to put your desired processing window on your laptop

Just guess though, I don’t a mac to test it right now
