Easy way: Notice when app changes display, store display.id for next startup. Or store it on exit.
Add configure options to select display device where app should be displayed after startup in a multi-monitor setup.
Maybe move the app there when the user changes the configur-option in the menu and store the display.id for next startup.
Use configured value in backend-code.
