The key to successful integration of gadgets is a stable wireless network that will connect the mobile device and TV into a single ecosystem. Unlike wired solutions, using Wi-Fi Eliminates unnecessary cables and allows you to control content from anywhere in the room. In this article, we'll take a detailed look at all available streaming methods, focusing on the native features of Apple's system and the specific settings of the South Korean brand's TVs.
It's worth noting that data transfer quality directly depends on your router's bandwidth and channel congestion.

To check for updates, go to the Settings menu and select General → About TV → Software UpdateIf the system prompts you to install a new version, be sure to accept it, as this often fixes compatibility issues and improves connection stability.
⚠️ Please note: Some budget LG TV models may not have a built-in AirPlay module, even if they support Smart TV. In this case, the only solution is to use third-party repeater apps or purchase an Apple TV set-top box.
Also, make sure your iPhone is connected to the same Wi-Fi network as your TV. Using guest networks or bands with AP Isolation can prevent devices from discovering each other. The router must support the standards. 802.11n or higher, preferably in the 5 GHz range to ensure sufficient video stream transmission speed without artifacts.
Using native AirPlay 2 on LG TVs

This significantly speeds up the connection process in the future, allowing you to stream content with a single tap.
| Parameter | AirPlay 2 (Native) | DLNA (Photo/Video) | Third-party applications |

| Latency | Minimum | Absent | High |
| Sound | Synchronized | Synchronized | Possible desynchronizations |
| Convenience | Built into iOS | Via the Photos app | Requires software installation |
It's important to understand that when using AirPlay, your iPhone's screen doesn't necessarily need to be on all the time if you're streaming video from supported apps like YouTube or NetflixIn this case, the phone acts as a remote control, and the video stream is sent directly from the internet to the TV, saving battery life. However, when using screen mirroring, the phone continues encoding the image, which can cause it to overheat.
Broadcast via LG ThinQ app
If for some reason the native AirPlay is unstable or not supported by your TV model, you can use the official app LG ThinQThis is a universal remote control and media center that allows you to not only change channels but also stream your iPhone's gallery content to the big screen.

Why might the LG ThinQ app not see my TV?
If the app doesn't find your TV, check if AP (Client Isolation) is enabled on your router, which prevents devices on the network from seeing each other. Also, make sure your phone's antivirus isn't blocking local connections.
Streaming video from browsers and third-party services
Many online cinemas and video services, such as YouTube, Vimeo or Okko, have a built-in Cast function that works independently of the AirPlay system settings.

Solving common connection problems
Despite the apparent simplicity, users often face a situation when the TV LG If your TV isn't showing up in the list of available devices on your iPhone, the first step is to check whether your router's firewall or antivirus software on your phone is blocking local connections. A simple restart of both devices often helps: unplug the TV for 10 seconds and then restart your iPhone, which will clear the network settings cache.
Another common cause is using different Wi-Fi frequencies. If your router is broadcasting two networks (2.4 GHz and 5 GHz) with different names, make sure both devices are connected to the same one. Some routers automatically switch devices between bands, which can temporarily disrupt the connection for discovery protocols.
If the problem persists, try resetting the network settings on your TV. To do this, go to Settings → Network → Wi-Fi connection → Advanced → Reset settingsAfter reconnecting to the network, restart the device search on your iPhone. In rare cases, changing the region in your TV settings may help, as some features may be geographically restricted.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the webOS firmware version. If you don't see the option you're looking for, please refer to the official user manual for your specific model, as manufacturers frequently update their menu structure.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Without a wireless network, connection is only possible using wired adapters. You'll need a Lightning-to-HDMI adapter (or USB-C-to-HDMI for newer iPhone models) and an HDMI cable. This will ensure the most stable connection without lag, but will limit your device's mobility due to the cable's length.
Why is there no sound when connecting via AirPlay?
Check your TV's audio settings. Sometimes, when connecting an external device, the sound defaults to the phone's built-in speakers. Also, make sure that the AirPlay settings on your iPhone are set to "LG TV" rather than "iPhone."
Video is lagging when streaming from iPhone to LG. What should I do?
Lag is most often caused by a weak Wi-Fi signal or channel congestion. Try moving closer to the router, disabling downloads on other devices, or switching the router to a less congested channel. Lowering the video quality in the source app settings can also help eliminate buffering.
Do all LG TVs support AirPlay?
No, native AirPlay 2 support was introduced in 2018 and newer models (B, C, E, W series, and some UHD models). Older models require third-party repeater apps installed on the TV itself via the LG Content Store or an external set-top box.
Is it safe to enter a code from a TV to an iPhone?
Yes, this is a standard security procedure. The code is displayed only on the TV screen and is valid only once for the first pair. This ensures that a neighbor or an intruder cannot connect to your phone and stream unwanted content without your physical presence at the TV.
