Yes, that works, I use it for camera, weather and the moving map, sometimes for ATC.
Open the window ( like camera), make it 'big' by pressing the icon left from 'x' (close), press this icon again. Then drag to your other monitor.
I must say that my second monitor is a laptop, connected with a program called 'spacedesk', i'm pretty sure that this works on a monitor as well
