This guide walks you through how to connect iPhone to LG TV using the most reliable methods, with quick reference information and troubleshooting tips.
| Connection Method | Speed / Quality | Setup Complexity | Best Use Case |
|---|---|---|---|
| AirPlay 2 (Wireless) | Good for HD video, low latency on 5 GHz Wi-Fi | Easy, requires same Wi-Fi network | Quick screen mirroring and media playback |
| HDMI Cable (Adapter) | Excellent, up to 4K HDR depending on cable | Very low, plug and display | Low latency gaming and guaranteed stable connection |
| LG TV web Smart Share | Local network streaming, HD capable | Moderate, app and browser required | Streaming from iPhone video gallery to TV |
| Third-party apps (e.g., MirrorLink) | Variable, may compress video | Moderate, app install and pairing | Extended interactivity and older TV models |
Check LG TV model and iOS support
Before attempting to connect, confirm that your LG television is a smart TV from 2018 or later and that it runs webOS 5 or higher. These models officially support AirPlay 2 and often appear in the source list on the TV input screen.
Update your LG TV firmware through Settings and also ensure your iPhone runs the latest iOS version for the best compatibility and security.
Set up wireless connection with AirPlay 2
Enable AirPlay on LG TV
Open Settings on your LG TV, go to General, then AirPlay, and enable Allow AirPlay. Confirm that Allow TV to be discovered by AirPlay devices is turned on. Make note of whether the TV requires a PIN for pairing, as some models enforce it when the TV is in use.
Connect from iPhone
Swipe down from the top right of your iPhone to open Control Center, tap Screen Mirroring, and select your LG TV from the list. If a code appears on the TV, enter it on your iPhone to complete pairing. Once connected, your iPhone screen or selected media will play on the LG TV with minimal delay.
Use HDMI adapter for wired reliability
Choose the correct adapter and cable
For the most stable connection, use a Lightning to HDMI adapter or a USB-C Digital AV Multiport Adapter, depending on your iPhone model. Pair it with a high-speed HDMI cable that supports 4K if your TV and source content require it.
Switch input and verify audio
Plug the adapter into your iPhone and the HDMI cable into the TV, then switch the LG TV to the corresponding HDMI input. You may need to set the TV input to the correct HDMI port and adjust Trust settings on the iPhone when prompted to allow video output.
Troubleshoot common connection issues
If your devices do not discover each other, start by checking that both the iPhone and LG TV are on the same local Wi-Fi network. Restart your router, TV, and iPhone to clear temporary glitches, and ensure that router settings are not blocking AirPlay multicast traffic.
When using an adapter, verify that it is supported by your iPhone and that the HDMI cable is not damaged. For slow or choppy video, lower the resolution on your iPhone or switch to a wired connection to reduce latency and improve stability.
Final recommendations for a stable iPhone to LG TV setup
- Prefer AirPlay 2 for quick, cable-free screen mirroring on compatible TVs.
- Use a Lightning or USB-C HDMI adapter and high-speed HDMI cable for 4K gaming and guaranteed reliability.
- Keep your LG TV firmware and iPhone iOS up to date to avoid compatibility issues.

FAQ
Reader questions
Why can't I see my LG TV when trying to use AirPlay from my iPhone?
Make sure both devices are on the same Wi-Fi network, AirPlay is enabled on the TV, and neither device has a firewall or parental control blocking discovery. Restart both devices and update firmware if needed.
Will connecting through an HDMI adapter work with 4K content from my iPhone?
Yes, if you use a high-speed HDMI cable and a supported adapter, your iPhone can output 4K video to compatible LG TVs. Check that the TV input is set to the correct HDMI port and that the cable supports the required bandwidth.
Can I use iPhone mirroring on an older LG smart TV that does not support AirPlay?
You can use third-party apps or streaming devices that cast from your iPhone to the TV, or connect via an HDMI adapter for a direct wired solution. Native AirPlay 2 requires webOS 5 or later on the television.
Is there any latency when playing games from my iPhone on the LG TV over Wi‑Fi?
Wireless AirPlay may introduce slight input lag during fast-paced gaming. For the lowest latency, use a wired HDMI adapter or ensure both devices are on a strong 5 GHz Wi‑Fi network with minimal interference.
