If you want to mirror your phone’s screen to your car via the TV Adapter using an HDMI to USB-C or Lightning adapter, you may encounter some common issues. Below, we explain the possible causes and how to fix them.
Common Symptoms:
You can hear audio, but there is no video.
You receive an error message when trying to play content, or the connection keeps dropping and reconnecting.
Your car screen remains black when connecting your phone via HDMI.
HDCP Incompatibility
If you are experiencing any of these issues, your HDMI adapter may not be HDCP-compatible (High-bandwidth Digital Content Protection). Many paid streaming services, such as Netflix, Amazon Prime Video, and others, require HDCP support. If your adapter does not support this protocol, your phone won’t be able to verify the TV Adapter’s certification, blocking video output.
To rule out compatibility issues with the cable or adapter, follow these troubleshooting steps:
Test different apps: Try playing content from an app that doesn’t require HDCP, like YouTube. If only certain apps are affected, it’s likely a content protection issue.
Check the adapter and cable quality: Ensure they are high-quality and properly connected.
Restart the TV Adapter and your phone: A restart can sometimes resolve connection issues.
Verify HDCP compatibility: Make sure you are using an HDMI adapter and cable that support HDCP.
Try a different HDMI adapter or cable: If the issue persists, test with a certified adapter to rule out compatibility problems.
Issues with Other Devices
If you experience similar issues with devices like Roku or Fire TV Stick, the problem might be with the TV Adapter. In this case:
Update the TV Adapter firmware to the latest version.
