To screen mirror your iOS device, ensure that it is connected to the same Wi-Fi channel and frequency (2.4 GHz or 5 GHz) as your Android TV. Once done, simply follow the steps below:
You may need to split the WiFi band into 2.4Ghz and 5Ghz if your device is unable to detect the TV.
Refer to your router manual or contact your Internet Service Provider for more information on WiFi band splitting.
Open your Android TV's Google Play Store app and download the "AirScreen" app.
Once done installing, open the app and complete the initial set-up.
On your iOS device, swipe down/up (depending on the model) the control center. Tap on "Screen Mirroring" and select your PRISM+ TV's name to start mirroring your device.
Note: The picture below is for reference as the name of your TV could be different.
