I want to display a different content to HDMI output on iOS. I can set a different content to be shown on the external output but if I disconnect the adaptor, it crashes.
I've already try the patch https://codereview.qt-project.org/c/qt/qtbase/+/354174 but it is still crashing.
Run the app, connect the adaptor, click on the button and the new content will be shown on the external display. Disconnect the adaptor.
