Hi @b0n3z,
Could you please specify what is not working or what functionality is missing?
I assume you want to use Tobii EyeX to work with multiple eye trackers on multiple screens? Or for one eye tracker to work over that very wide angle?
Or is the problem that EyeX actually does not work on the monitor it is attached to when you have all three running using nVidia Surround?
Thanks for the details.
