Display overlay, output issue

[Isse]

Hi peeps, newbie here

I have laptop display as primary and external displays, LEDs and more and I came across a problem recently. The issue I had was really annoying as I could not slice as I wanted noor use the screen as I wanted.
As of now I have 3x screens connected to my macbook pro, a 2015, i7 with dual graphic-cards, AMD Radeon R9 M370X 2GB DDR5 & Intel Iris Pro 1536 MB shared memory and this setup is so that I can figure out why, how come this happened.

Basically I can not get playback on any other screen but the one on the laptop :-/
when I press identify display it identifies all 3 on the laptop, and nothing at all happens on 2 external screens (see picture)
And if I open advanced the sliced window appears on the laptop screen, covering resolume entirely...

atm I can only use windowed and drag/drop to second screen but as it is I can not make custom slices as the software and the advanced screen window and all is on the same screen :-/

I have "this use as separate space" funktion marked with a checker as "in use" and it makes no difference

I really need to get this working, It's really a huge mindf**k for me, and I can't figure it out ((

Start Resolume, then right click on the Resolume program icon in the dock and hover over Options,
then select the Assign to None option.
You only see this option if you have multiple desktops, which I assume you do, or did at one point.
If you don't then create some to see this option, looks like it's sticky even if you don't have multiple desktops. because... OSX...

This should help with this.

So simple, now I feel a bit shame lol but in the end of the day IT WORKS!

Brilliant! Thank you!
