To connect your iPhone to an LG Smart TV, you can use AirPlay, HDMI adapter, or screen mirroring depending on your TV model and preferences. AirPlay (wireless): Ensure both devices are on the same Wi-Fi network. Swipe down from the top-right corner of your iPhone to open Control Center, tap Screen Mirroring, and select your LG TV from the list. Your iPhone's display will mirror on the TV. HDMI adapter (wired): Purchase a Lightning to HDMI adapter, connect it to your iPhone's charging port, and plug an HDMI cable into the adapter and your TV's HDMI port. This provides a direct connection without needing Wi-Fi. LG TV app: Some newer LG Smart TVs support AirPlay natively. Check your TV's settings under Network or AirPlay to enable it if not already active. Your TV remote or the LG ThinQ app on your iPhone can help navigate settings. Casting apps: Apps like YouTube, Netflix, and Apple TV+ have built-in casting features—tap the cast icon within the app and select your LG TV. Troubleshooting: If AirPlay doesn't work, restart both devices, forget and rejoin your Wi-Fi network, or update your iPhone and TV software. Older LG TVs may not support AirPlay, so check your model's compatibility. The HDMI adapter method is the most reliable universal solution if wireless options fail.
