Hello STarrant,

Thanks for that info and choosing the Apple Support Communities. If I understand correctly, you are unable to play a movie from your iPhone to a TV via HDMI. To help with this issue, please follow these steps from this article on your issue:

If an app doesn't display video or play audio

The app might not be compatible with your adapter. Check compatibility on the app's info page in the App Store or contact the developer.

If an alert says that an HDCP-compatible device is required

Your content might not be compatible with your adapter. Movies, TV shows, and certain streaming video apps require High-Bandwidth Digital Content Protection (HDCP). If you try to play these movies, shows, and streaming videos using a non-HDCP digital connection—like the Apple VGA Adapter—an alert will ask for an HDCP-compatible device.

If you need help with other issues

Disconnect and reconnect your adapter from your iPhone, iPad, or iPod touch and from your TV, monitor, or projector.

Make sure that your VGA or HDMI cable works, since the issue could be with the cable.

Remove any VGA or HDMI extension cables or converters. Accessories that convert a VGA or HDMI signals to different video formats (DVI, Composite, Component) aren't compatible.

Make sure that you have the latest version of iOS.
