Main screen and dock move to second display

Hi konstadinos.k,

I understand you want your MacBook Pro to be the default display for your DJ software when you have a second display connected to it. Take a look at the article below that explains all of the options for extending or mirroring your displays. I've highlighted some key information below that may be helpful in your situation. Even though the article is for Mavericks, the info should still be applicable.

You can also assign an app to a specific display space from the app's menu in the Dock. Windows assigned to a space always open there when the display you specified is connected.

The blue boxes in Displays preferences represent each display that's connected. The size of each box is relative to the current resolution of each display. In this example, the smaller box on the left is the display of a 13" MacBook Pro while the larger box on the right represents the Apple 27" Thunderbolt Display.

Drag any of the blue boxes to change the location of a display in relation to your additional screens. You can use this feature to make sure your connected displays match their real world location when navigating windows. The white bar at the top of the blue box represents the menu bar. Drag the white bar onto the blue box representing the display you want as your primary display.

Hope that helps ...
