You are talking about a single window that spans several monitors right?

No, I mean the app that has multiple windows, each with own camera (Target Display setting at the bottom of the image below)

Hi,
I'm working an app that have multiple UIs, each displayed on different window/monitor. I'm trying to use Noesis for that - but seems like app is getting a proper mouse input from main display only.
Can Noesis be used in Unity on multiple displays?
