My iPhone hdmi adapter is only playing sound and no picture to tv

Hey there djbalemi,

We understand you're having trouble with audio output to your TV via your HDMI adapter. We'd be happy to provide information to help you narrow this down.

Start out by checking the app you're using to output the video via HDMI. Many apps have protections in place to not allow the audio or video to be played on anything other than the main device. However, if this is a video you recorded on the iPhone itself and it plays with audio just fine when played on your iPhone. You can move on to the next section.

Test out to see if the HDMI cable may be the issue. Do you have another cable available that works correctly with a different device? Test this cable with the adapter and your iPhone.

If the issue continues even with a new cable, the issue may be with the adapter itself. Test the adapter with another device if possible. If the issue persists with another device, then you would need to replace the adapter.

Kind regards.
