Hmmmm i'm not sure about the display issue. Looking at my setup now, i've also got "display" three times, (i should update my set-up post) but it works fine on my system. The display disappears after it starts.
Maybe try putting a fourth "display" in?
Other than that, i'm not sure.

I don't know how to pause and stop during the switchover though...must have been someone else!

Have a good one.
