Modern smartphones such as iPhone 11, have become powerful multimedia centers, allowing you to store huge libraries of videos and photos. However, to comfortably view content on a large screen, it is often necessary to output images from a mobile device to a TV. Owners of these devices Apple and televisions LG with support Smart TV can easily implement this using a wireless connection Wi-FiThe technology allows for high-definition video transmission without the need for unnecessary wires.
The main tool for this process is the function AirPlay 2, which is built into the operating system iOSIt ensures stable data and audio transmission, minimizing latency. It's important to understand that for successful synchronization, both devices must be on the same local network. In this article, we'll cover all setup steps, potential issues, and alternative connection methods if the standard method doesn't work.
Hardware and software requirements
Before you begin setting up, you need to make sure that your equipment meets the technical requirements for wireless broadcasting. iPhone 11 supports all the necessary protocols, but the TV must be modern enough. We are talking about models LG with a platform webOS version 4.0 and higher. These are typically devices released in 2018 and later. Older models without the feature AirPlay 2 will require the use of third-party applications.
A stable network is critical Wi-FiBoth devicesβthe smartphone and the TVβmust be connected to the same access point. Using a guest network or different frequencies (2.4 GHz and 5 GHz) on some routers can create client isolation, making devices impossible to discover. Also, make sure the "Shared Wi-Fi" feature is enabled on the TV. Mobile TV Connectivity or a similar option in the settings menu.
β οΈ Note: If your router uses AP Isolation mode, devices will not be able to "see" each other. This feature is often enabled in public areas, but can also be enabled in your router's default settings at home for security reasons.
Software also plays a key role. iPhone 11 the current version must be installed iOS, since support AirPlay 2 was introduced in earlier versions, but is constantly being improved. On the TV side LG It is recommended to check for firmware updates webOS through the menu Settings β Support β Software UpdateThe lack of fresh patches may lead to unstable operation of the data transfer protocol.

Make sure the switch is in the position On.
After activating the feature, the TV may prompt you to configure security settings. You can choose to require a code for each connection, or allow automatic connection for previously used devices. For home use, it's more convenient to choose the option Only on first connection or No code required, if you are confident in the security of your network Wi-Fi.
| Setting parameter | Recommended value | Description of influence |
|---|---|---|
| AirPlay status | Included | Activates signal reception from Apple devices |
| Require code | When connecting for the first time | Balance between convenience and security |
| Device name | Name visible in iPhone list | |
| IPv6 protocol | Auto | Required for AirPlay 2 to work properly. |
It is important to note that some models require the feature to be enabled. Quick Start+ or similar energy-saving options to ensure the TV remains visible on the network even in sleep mode. If the TV is turned off programmatically, it may not appear in the list of available devices on iPhone 11.
Instructions for connecting iPhone 11 to LG TV
Once your TV is ready, you can move on to setting up your smartphone. Make sure that iPhone 11 connected to the same network Wi-Fi, as well as the TV. Open Control center on a smartphone. On models with Face ID, which includes iPhone 11, this is done by swiping down from the upper right corner of the screen.
In the menu that opens, find the icon Screen mirroring (two intersecting rectangles). Click on it. The system will begin searching for available devices on the local network. After a few seconds, your TV should appear on the list. LG. Select it.
βοΈ Connection algorithm
When connecting for the first time, a confirmation message may appear on the TV screen. iPhone 11 A four-digit code will be displayed, which you must enter using the TV remote or confirm the connection if you selected the code-free mode. After successful authentication, the image from your smartphone screen will instantly appear on the TV.
β οΈ Note: If the code does not appear or the connection is lost, try resetting the Wi-Fi module on the TV by completely disconnecting it from the power supply for 30 seconds, and then turning it on again.
