Does the Apple TV app display 4K content to an external monitor from an iPad Pro after the iPadOS 17.1.1 updates?
I have an iPad Pro connected to my 4K monitor through an Apple USB-C to Digital Multiport Adapter and an HDMI cable. Disney+, Starz and Netflix display 4K content without any problems. The Apple TV app plays audio but no 4K video, showing a black screen on the monitor, with no error message on the iPad screen which shows the player controls. Max changed their subscription tiers, and its Max app shows the same symptoms as the Apple TV app, but the symptoms are explained by the subscription changes. I have not seen any changes in the Apple TV+ subscription regarding being able to display 4K content. The Apple TV app used to display 4K video before the iPadOS 17.1.1 update.
I have troubleshooted with Apple Support, but they have yet to test this setup on one of their iPad Pros with a 4K monitor. We have yet to find anything wrong with my setup.
iPad Pro, iPadOS 17
