Run two apps simultaneously: One on device and one on external monitor

[AC Question]

Samsung's Galaxy Tab Pro 12.2 supports multi-window. Also mirroring to an external monitor (MHT/HDMI) is not a problem.
But can I run two full-screen apps simultaneously on the two screens?
Thanks!

Not one on each screen - mirroring means just that - the external screen is a mirror (without reversing left to right) of the phone's screen.
