Frequently Asked Questions

Why does Chromecast say source not supported for Netflix?
Netflix uses DRM protection for certain content that cannot be cast from mobile apps. Try using the Netflix website in Chrome browser on a computer, or use a Chromecast with Google TV which has native Netflix support.
Can I cast protected content like movies I purchased?
Most purchased movies from services like iTunes, Amazon Prime Video, or Vudu have DRM restrictions that prevent casting from mobile apps. Use the native apps on Chromecast with Google TV or cast from a computer browser instead.
What does unsupported source mean on Chromecast?
Unsupported source means the content format, DRM protection, or streaming protocol is not compatible with Chromecast's casting capabilities. This is common with premium content, live TV, or certain video formats.
How do I know if an app supports Chromecast?
Look for the Cast icon (rectangle with Wi-Fi waves) in the app's interface. Apps that support Chromecast will display this icon prominently, usually in the top-right corner or video player controls.
Why can't I cast from iPhone to Chromecast?
Some iPhone apps use AirPlay instead of Chromecast protocols. Ensure you're using apps with built-in Chromecast support, or use Chrome browser to cast websites instead of relying on AirPlay.
