I am being asked to write a pro bono app for a non-profit museum to allow an iPad Pro 2019 to provide a user-friendly interface on the iPad Pro so visitors can select video or pictures to be displayed via the USB-C connector on a large screen (presumably 4K) external monitor. No Apple TV. This is presuming they had a USB-C capable HD monitor, of course.
This is different than simply mirroring the iPad Pro display. They'd like the iPad Pro display to stay showing all the options.
It's unclear to me whether the current Apple iOS APIs allow this. You can do this on the Windows side from a touch-screen laptop, but I really don't want to go there. As a developer, I know I can code a beautiful user interface on the iPad Pro.
We must determine this in advance before they buy the iPad Pro and monitor.
