You should be able to just move it to the display you want to have it on. You may need to exit the full screen mode to get to the window and then just drag the window to the right display. It will remember the placement next time you open it.
If I remember correctly you can double click inside the full screen view to make it a window. Sorry I am not able to verify this – I am on vacation and only on my phone right now. 😉
