    I can't get the new Input System to work with Multiple displays.

    The setup:
    • Unity 2021.3.2f1
    • Input System 1.3.0 and 1.4.2 (neither work)
    • Windows 10
    • 7 Displays
    • Works in the Editor
    • Does not work in the build
    • All mouse input goes to the first display
    • I am using InputSystemUIInputModule, not StandaloneInputModule
    Things I've tried:
    • World Space, Screen Space--Camera, and Screen Space--Overlay Canvases, one per Display
    • A single World Space Canvas covering all displays
    • Changing InputSystemUIInputModule.PointerBehavior
    • Having a separate MultiplayerEventSystem for each screen rather than a single EventSystem
    • All permutations of the above.
    The mouse works in the legacy input system but touch doesn't. I've switched over to the new system hoping it will work with touch, but I can't seem to get even the mouse to work.

    Any thoughts would be much appreciated!

    To clarify, this is with the UnityEngine.UI.

    I still haven't found a solution so I'm going back to the old input system and hacking something up for multiple touchscreens.
