Hi - on iPadOS16 beta1, we have been experimenting with connecting to external 1080p and 4k monitors using TypeC on latest M1 iPads.

It appears to only display full-screen (non-mirrored) when there is a HID device such as mouse connected. This makes sense as you need to be able to control the screen independently.

However for a touch screen external display (e.g. INNOCN) that supports multi-touch, it does not work. iPadOS (and macOS) do not have any multi-touch drivers.

Is there plans for iPadOS (and indeed eventually macOS) to support external multi-touch screens?

Well, it seems that there is some level of support I just tried verbatim PMT 14 and the OS iPad shows as if a mouse is connected whenever I touch the external screen. The response from the os is not correlated to the touch itself but at least there is some attempt, it’s not usable at all but hopefully soon will get proper multitouch on external screens
