iPhone/ iPad HDR Set Up

  • The only addition to the frontend is an “SDR / HDR” switch in the presenter settings.
  • When you click “HDR” it will default the stream to “10-bit” delivery.
  • Selecting HDR just allows us to capture HDR metadata going into the Flexbox and passes that through the pipeline.
  • If it doesn’t detect any HDR 10 metadata then it will use a sensible default.

How to Setup your Apple TV for HDR

You should configure your Apple TV to be in HDR mode (not Dolby Vision HDR) and for the refresh rate to match the frame.

By default your Apple TV will be set to 4K HDR (HDR 10). You should change the resolution to 1080p. The refresh rate is also set to 60 (59.94Hz) or 50 depending on your region. It’s fine to run at this refresh rate, but if you want true 24fps, for example, then you should switch to 24Hz.

Here is an example of how to set your dynamic range on your Apple TV to be HDR and to match a source frame rate of 24fps for true 24fps.

  1. Open the settings App from the main menu
