Main video on External display

In Djay for ios, I have an adaptor that can mirror my iphone screen to an external projector. Is there a way to project main video to external projector while keeping mixer with two video decks in iphone (video mixing Dj)?

Hi Andre,

Yes this is possible, you can find further information on which adapter you need via

Thanks Lukas for your reply. But the problem is that these adapters makes mirror of the iphone screen. And when you are mixing for a projector you want that the audience see the master video, not my mixing work. I would like to see the same implementation of djay pro for mac that is the option to choose the HDMI screen to project the master video only.
