Follow our instructions to enjoy high quality content.
Checking compatibility and preparing equipment
Before you begin active setup, you need to make sure your equipment is technically ready for operation. Not all TV models LG support native operation with Apple protocols. This primarily applies to models released before 2018, where the functionality AirPlay may be absent. However, even on older devices, streaming can be organized using alternative methods.
Make sure your TV's software is updated to the latest version. Manufacturers regularly release patches that improve wireless connection stability and add support for new codecs. You can check your firmware version in the settings menu by following this path: Settings → All settings → General → About TV.
The quality of the wireless network signal is also important. High-definition video streaming (4K or Full HD) requires a stable connection. If the router is too far from the TV, lag or image artifacts may occur. Ideally, the distance between router and the receiver should not exceed 10 meters without obstacles.
- 📺 LG TV model supporting webOS 4.0 and higher (for AirPlay 2).
- 📱 iPhone 4S and newer with the latest version of iOS.

⚠️ Note: If your LG TV doesn't natively support AirPlay 2, don't despair. There are third-party receiver apps available from the LG Content Store that emulate the Apple protocol.
Setting up AirPlay 2 on an LG TV
Let's start with the highest quality and most convenient way to transmit content, which provides minimal latency and high resolution. Technology AirPlay 2 Built into many modern LG models, starting with the 2018-2019 series, this feature is available for purchase. Activating this feature requires no additional software installation; simply configure the built-in menu correctly.
Take the remote control and press the button Home (house) to access the main panel. Find the app icon Apple AirPlay or AirPlay HomeIf this is your first time seeing it, the system may prompt you to accept the terms of use or perform initial setup. Agree to the terms to activate the signal reception module.
In the AirPlay settings menu, you can configure security settings. We recommend setting a passcode to prevent neighbors or guests from accidentally connecting to your TV and playing their own videos. You can also set the device name here, which will appear in the list of available devices on your TV. iPhone.

Please pay attention to the power saving settings. Some TV models may disable the Wi-Fi module when entering sleep mode, which will interrupt the connection. In the section Settings → General → Eco mode Make sure that fast boot or display shutdown features are not blocking network interfaces.
Connecting iPhone to TV via Control Center
Once the TV is prepared, we move on to setting up the smartphone Interface iOS is the same for all models, but the layout of the elements may differ slightly depending on the presence of the Home button. The process of starting a broadcast, or Screen Mirroring, takes a few seconds.
Open Control Center on your iPhone. On models with Face ID (iPhone X and later), swipe down from the top-right corner of the screen. On models with a Home button (iPhone 8 and later, SE), swipe up from the bottom. Find the icon. Screen mirroring (two rectangles).
Your LG TV should appear in the list of available devices that opens. Its name will match the one you set in your TV settings or the default model name. Click on it. If you set a passcode on your TV, a field for entering numbers will appear on your smartphone screen. Enter the code using the virtual keyboard.
Action: Swipe down (right) → Screen Mirroring icon → Select LG TV → Enter PINAfter successful authorization, your iPhone's screen will be mirrored on the TV. This is called mirroring.

- 🎮 Input lag is minimal, allowing you to use your phone as a controller for simple games.
- 📉 If the Wi-Fi signal is weak, the system will automatically reduce the image quality to maintain smoothness.
Streaming videos from apps (YouTube, Netflix, Kinopoisk)
Streaming video content from popular streaming services deserves special attention. Unlike full screen mirroring, this technology uses Cast Or built-in TV players. This is a more energy-efficient option, as the smartphone only acts as a remote control, and the video is buffered and played directly from the network by the TV.
Launch an app, such as YouTube or Netflix, on your iPhone. Make sure you're logged in to the same account as your TV (this is important for some services, like Netflix, to see your viewing history). In the video player interface, look for the casting icon—usually a rectangle with Wi-Fi waves in the corner.
Tap the icon and select your LG TV from the list. The video will play on the big screen, and controls will appear on your smartphone: a rewind slider, pause button, and volume control.

| Parameter | Mirroring (AirPlay) | Broadcast from the app (Cast) |
|---|---|---|
| iPhone battery drain | High (screen is on, coding is in progress) | Low (screen can be turned off) |
| Image quality | Depends on Wi-Fi signal | Maximum (depending on TV internet speed) |
| Ability to use a phone | Limited (everything is visible on TV) | Full (screens are independent) |
| Subtitle support | Like on the phone | Native TV support |
It's worth noting that some apps may require additional authorization. For example, when connecting to a Smart TV for the first time through an app, you may be asked to confirm your login on the TV itself using the remote control. This is a security measure to protect your account.
⚠️ Note: App interfaces (YouTube, IVI, Okko) may be updated, changing the location of the broadcast button. If you don't see the icon, check if it's hidden in the "More" menu (three dots).
Using third-party apps for broadcasting
In situations where native AirPlay support is missing or doesn't work correctly, third-party solutions come to the rescue. The LG Content Store offers a number of utilities that help create a bridge between iOS and your TV. Popular options include TV Assist, AirScreen or Web Video Cast.
They work in a similar way: you install the app on your TV, launch it, and it creates a virtual receiver visible to your iPhone. These programs often support not only video but also photo and music streaming. Some of them have their own file manager for accessing media on your smartphone.
Using these apps often requires installing a companion app on your iPhone. Once paired via a QR code or local network search, advanced features become available. For example, you can stream video formats that the standard LG player doesn't support, as the decoding will be handled by the smartphone.
Is it worth installing paid versions of broadcasting apps?
Paid versions typically remove ads that may appear on your TV screen before you start watching and provide access to 4K streaming. The free version is sufficient for a one-time use, but a paid subscription is more convenient for regular viewing.
However, it's important to keep security in mind. By installing third-party software, you grant it access to your local network. Use only trusted apps with high ratings and numerous reviews. Avoid unknown utilities that request excessive permissions.
Troubleshooting and troubleshooting
Even with a perfect setup, glitches can occur. The most common issue is that the TV simply isn't visible in the AirPlay device list. In 90% of cases, this can be resolved by simply rebooting the router and both devices (TV and iPhone). Network protocols sometimes freeze, and a fresh start clears the cache.
Another common scenario is audio and video desync. This is a classic sign of insufficient Wi-Fi bandwidth or an overloaded TV processor. Try lowering the playback quality in the source app or moving the router closer. Disabling Bluetooth on your iPhone also helps, as it operates on the same 2.4 GHz frequency and can cause interference.
If the problem is software related, try resetting the network settings on your TV. In the menu Settings → Network → Advanced Wi-Fi Settings You can find a reset option. After doing so, you'll need to re-enter your Wi-Fi password. This often helps if your router's DHCP or DNS settings have changed.
- 📶 Make sure that AP Client Isolation is not enabled on your router, which prevents devices from seeing each other.
- ⏱ Check that the time and date on your TV and smartphone match (a difference of more than 5 minutes may block security certificates).
- 🛡 The antivirus software on your router or in your ISP's network should not block local ports used for DLNA/AirPlay.
- 📱 Update iOS to the latest version, as Apple is constantly patching wireless transmission bugs.
⚠️ Note: Specifications and settings menus may vary depending on the webOS version and year of your LG model. If you don't find the option described, please refer to the official documentation on the manufacturer's website.
