Why can’t I screen mirror my iPhone 12 Pro Max with my roku tv it’s connected to the same Wi-Fi

Hi lil252,

We'd like to share some helpful information regarding screen mirroring and the expectations for this. It looks like you came to us from Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch which mentions "Connect your iPhone, iPad, or iPod touch to the same Wi-Fi network as your Apple TV, AirPlay 2-compatible smart TV, or Mac".

AirPlay system requirements - Apple Support can help you to determine if your Hisense smart TV works with Apple Airplay, or you can check the manufacturer details for your specific model: Hisense - Contact Us

Since you mentioned that you're using Roku, these steps may be beneficial: How to use AirPlay and HomeKit with your Roku streaming device

If you're still unable to use AirPlay with your device, and Hisense has confirmed that your smart TV is compatible, reach out to Roku support here for additional assistance: Roku Support

Thanks for using Apple Support Communities.
