iPadOS 27 update breaks external display presentation functionality
Key points
- iPadOS 27 causes external displays to mirror the iPad screen when switching apps.
- This exposes private notes and poll results during presentations.
- The issue affects apps like GoodNotes, Keynote, and PowerPoint differently.
- The change replaces a less intuitive but functional iPadOS 26 behavior.
Presentation Feature Broken in iPadOS 27
The recent iPadOS 27 update has introduced a significant regression in how iPads handle external displays during presentations. Previously, users could project a presentation or document via AirPlay to an external screen while simultaneously using other applications on their iPad for notes or other tasks. This functionality allowed for a dedicated presenter view on the external display, keeping private information hidden from the audience.
Impact on Presenters and Educators
With iPadOS 27, tapping on any app other than the presenting application causes the external display to switch from the presentation view to mirroring the entire iPad screen. This means that audiences can see private notes, poll results, or other sensitive information intended only for the presenter. The sudden changes in display content are also distracting for viewers, disrupting the flow of presentations in educational and professional settings.
App-Specific Behaviors
The impact of this change varies across different applications. In GoodNotes, the presenter view can be restored by tapping back into the app. However, in Keynote, the presentation exits entirely, and in PowerPoint, the application enters a state requiring a restart of the presentation. This inconsistent behavior adds further complications for users relying on these apps for presentations.
Change from iPadOS 26
The previous iPadOS 26 system for controlling external displays was less intuitive, requiring users to swipe up and select an app from the dock to take over the external display. While complex, it allowed for a stable presentation view. Apple's new approach in iPadOS 27, where the most recently tapped app dictates the external display, is described as a worse solution that compromises presentation integrity.
