Unfortunately, the solution with the Chroma Controller didn't pan out, there are some probolems with the functionality of the Controller. The controller does not boot when the system is powered on only about ~20 seconds after which is nit-picky but a bit annoying. Even worse the controller doesn't seem to respond to input from OpenRGB before resetting the controller using the Razer Plugin which is a bit of a deal-breaker.
I think I'm gonna return it, but on that note, I am a bit curious as to the solution with the Arduino Pro Micro, how complex is it to build something like that? and what are the limitations in terms of power etc?
Hmm, hadn't thought of just setting all the displays to mirror mode, might want to test what that does (especially since the displays are of varying resolutions and refresh rates). I suppose it could work.
I have thought of a physical switch but i haven't had any luck finding a prebuilt one and I don't much have the electronics know-how to build one.
