2 Monitore: Bild auf dem zweiten angeklickt aber öffnet sich auf dem ersten?

Windows usually learns from yourself where you want to have a program/window by closing it where it should start next time.

The problem will be that this is probably not true for the game because it is just a child process. This is more about the app than Windows. Because if the app does not define a monitor, Windows will definitely take the main screen.

In some games, you can explicitly select the screen on which the game is to run, in do stop ledier, depending on how clever the developers were.

I guess you don’t want to change the main screen. Because I don’t think of anything else.
