Find out what to do when you have the following issues.
If you see video but can't hear audio
Make sure that you're using a Digital AV adapter (which has an HDMI port). If you're using a VGA adapter, it doesn't carry audio signals. To hear audio with a VGA adapter, you need to connect to the headset jack on your TV, monitor, projector, or stereo.
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.
For more help, contact Apple Support, to set up service for your:
1. To find your accessory's model number, connect it to your iOS device and go to Settings > General > About > Apple HDMI Adapter.
2. The iPhone 4, iPad (1st generation), and iPod touch (4th generation) only display videos, photos, presentations, and slideshows on a secondary display. You can't mirror the entire screen."
Thanks!
