You can cast from your iPhone to a TV using several methods, primarily relying on Apple’s AirPlay technology for compatible smart TVs and Apple TV, or through app-specific casting for devices like Chromecast. Here’s a breakdown:

1. AirPlay (for Apple TV or AirPlay 2-compatible Smart TVs):

• Mirroring your entire iPhone screen:
  1. Connect to the same Wi-Fi network: Ensure your iPhone and your Apple TV or AirPlay 2-compatible smart TV are connected to the same Wi-Fi network.
  2. Open Control Center:
     • iPhone with Face ID: Swipe down from the top-right corner of the screen.
     • iPhone with a Home button: Swipe up from the bottom edge of the screen.
  3. Tap the “Screen Mirroring” button: It looks like two overlapping rectangles.
  4. Select your TV: Choose your Apple TV or AirPlay 2-compatible smart TV from the list.
  5. Enter the AirPlay passcode (if prompted): If a passcode appears on your TV screen, enter it on your iPhone.
• Streaming video or audio:
  1. Connect to the same Wi-Fi network: Ensure your iPhone and your Apple TV or AirPlay 2-compatible smart TV are connected to the same Wi-Fi network.
  2. Open the app: Launch the app with the video or audio you want to stream (e.g., YouTube, Apple Music, Netflix).
  3. Tap the AirPlay icon: Look for the AirPlay icon (a rectangle with a triangle pointing upwards). In some apps, you might need to tap a different button first (like the Share button), then find the AirPlay button.
  4. Choose your TV: Select your Apple TV or AirPlay 2-compatible smart TV from the list.

2. App-Specific Casting (for Chromecast-enabled TVs):

• Many apps have built-in support for Chromecast.
  1. Connect to the same Wi-Fi network: Make sure your iPhone and your Chromecast-enabled TV are on the same Wi-Fi network.
  2. Open the app: Launch the app you want to cast from (e.g., YouTube, Netflix, Spotify).
  3. Look for the Cast icon: It usually looks like a rectangle with Wi-Fi waves in the corner.
  4. Tap the Cast icon: A list of available Chromecast devices will appear.
  5. Select your TV: Choose your Chromecast-enabled TV from the list. The content will then play on your TV.

3. Using Third-Party Apps:

• There are third-party apps available on the App Store that claim to offer casting functionality to various smart TVs (including those that don’t natively support AirPlay or Chromecast). Some popular options include:
  • AirBeamTV
  • Replika
  • DoCast
  • Mirror for [Your TV Brand] (e.g., Mirror for Samsung TV, Mirror for LG TV)
• Follow the specific instructions within these apps to connect to your TV. Compatibility and reliability can vary with these apps.
