Ambient Lighting for Multiple Monitors?

I've just gotten Ambient Lighting working using an Arudino / Adalight but it seems you can only capture from a single monitor. As I have a triple setup I'd obviously like to capture all three monitors but I don't see any way to do this.

Am I missing something or is this just not possible?

BTW while I'm using triples I can not use Nvidia Surround as my 3 monitors are different aspect ratios (center 32:9 with dual 16:9 on the sides). So I can't just setup a single monitor in Windows, I would need Simhub to be able to capture from all three.

Thanks!!
