Connect multiple display glasses to one computer

Hey,

we want to connect both the small and the big looking glass display to the same PC. They are both recognized and we can move windows to any of them. We can also start 3D scenes on both displays but the correct 3D effect only appears on the display which was first connected to the PC.

I think we have to somehow specify which USB port belongs to which connected display. Is there any ways to do this at the moment?

Best Regards,
Darius
