Hi 300213,
Thanks for visiting Apple Support Communities.
It sounds like you're using an Apple Digital AV Adapter to display video from your iPad on a TV using an HDMI connection.
Although an Apple TV allows you to use the AirPlay feature of iOS, you should also be able to use the adapter to play video.
I recommend starting with these tips to troubleshoot the connection between your iPad and TV:
iOS: About Apple Digital AV Adapters
If you encounter an issue using the Apple Digital AV Adapter or VGA Adapter:
- Disconnect and reconnect the adapter from the iOS device and display.
- Connect directly to the TV, projector, or external display using a known-good VGA or HDMI cable.
- Remove any VGA or HDMI extension cables or converters.
- Note that accessories that convert a VGA or HDMI signal to other video formats (DVI, Composite, Component) are not supported.
- Ensure that you are using the latest version of iOS. Some Apple Digital AV Adapters require iOS 5.1 or later.
Note: When using an Apple Digital AV Adapter manufactured before early 2012 with iPad (3rd generation), you may see the "This accessory is not supported" alert. Dismissing the alert will allow you to use the adapter.
For optimal performance, you may need to adjust the video resolution or settings for your display. If your display offers an "auto detect" or "factory default" setting, you may be able to use these options to optimize video resolution and display.
Best Regards,
Jeremy
