I had almost the same scenario while recording tutorial videos, and the solution I ended up with was from here https://mac.eltima.com/docast-stream-mirror/ Stream iPhone to TV . It’s great for long, uninterrupted work sessions because it keeps the stream stable even after hours of use. I also noticed that the color accuracy is much better compared to other apps I tried, which really matters when you’re teaching design or editing software. The interface is straightforward too, so switching displays doesn’t interrupt the workflow!
