Change display order between second and third display
I have a MacBook Pro Retina 15" (2012) with 2 external displays (Dell 27 and Samsung 24). I use the Dell as main display. My problem is with FCPX. I want to use my Samsung 24 as Second Display to see my video material in it with the option "Show events in second display", but OSX set the macbook display as second and the samsung as third. So, I only can see the events in the macbook and the timeline in the Dell. (Unless I close the Macbook. losing one display. I'd rather keep the 3 to use one of them (macbook) with a Finder window).
Anyone can help me with this or is impossible to change teh order between the macbook display and the Samsung 24?
