Modern technologies make it possible to transform the living room into a true multimedia center, where content from a smartphone instantly appears on the big screen. For owners of Apple devices and LG TVs, this task is accomplished without unnecessary wires thanks to technology AirPlay and built-in Smart TV features. You no longer need to search for HDMI cables or connect complex adapters if both devices are on the same network.
The synchronization process usually takes just a few seconds, but there are a number of nuances that can affect connection stability. Understanding how wireless data transfer protocols work will help avoid delays and audio desynchronization. In this guide, we'll cover all methods in detail, from native iOS tools to third-party apps.
Particular attention should be paid to router requirements, as it acts as the intermediary for video stream transmission. A weak signal or congested frequencies can cause interruptions. Let's look at how to prepare your network and devices for a perfect picture.
Preparing equipment and a Wi-Fi network
Before you begin setting up, you need to make sure that your LG TV Your iPhone and your device are connected to the same wireless network. This is a fundamental requirement; if ignored, the devices simply "don't see" each other in the list of available receivers. Make sure Wi-Fi is enabled on both devices and there are no guest access restrictions, which often block local communication.
It's also important to ensure that your devices' software is updated to the latest versions. LG TVs use the operating system webOS, which receives regular security and functionality updates. Older firmware versions may not support the latest encryption standards or AirPlay 2 protocols.
β οΈ Attention: If your router broadcasts the network on two frequencies (2.4 GHz and 5 GHz) with the same name, try temporarily separating them or forcing both devices to connect to the 5 GHz band for more stable transmission of high-definition video.
To check the current software version on your LG TV, go to the settings menu. The path may vary depending on the model year, but it typically looks like this: Settings (gear) β All settings β General β About TV β Check for updatesIf the system prompts you to update, be sure to do so before attempting to connect.

Using the native AirPlay 2 feature
Since 2019, most LG models support the technology AirPlay 2 "Out of the box." This is the most reliable method, requiring no additional software. The feature is built directly into the webOS shell, ensuring minimal latency and high image quality. To start broadcasting, you don't need to download anything from the App Store.
The process of starting Screen Mirroring is intuitive. Open Control center On your iPhone (swipe down from the upper-right corner on models without a Home button or swipe up on older models). Find the "Screen Mirroring" icon (two rectangles) and select your LG TV from the list that appears.
In some cases, AirPlay may be disabled in the TV's settings. To activate it, go to the LG main menu and find the app. Apple AirPlay and HomeKit or go to Settings β Connections β AirPlayMake sure the switch is in the "On" position. You can also configure this to require a password each time you connect or to restrict access to devices on the same network.
Transmission quality depends on signal strength. If you notice artifacts or choppiness, move closer to the router. The AirPlay 2 protocol adaptively adjusts the bitrate, but in poor signal conditions, connection stability is prioritized over resolution.
| Parameter | iPhone requirement | LG TV requirements |
|---|---|---|
| operating system | iOS 12.3 and later | webOS 4.0 and later |
| Protocol | AirPlay 2 | Built-in AirPlay support |
| Net | Wi-Fi (802.11ac preferred) | Wi-Fi (same network) |
| Bluetooth | Enabled (for detection) | Enabled (optional) |
Alternative Methods: LG TV Plus App and Smart Share
If for some reason the native AirPlay doesn't work or your TV model is an earlier generation (before 2018), you can use the proprietary app LG TV PlusIt's available in the App Store and offers advanced management features, including transferring photos and videos from your gallery.
After installing the app, launch it and follow the on-screen instructions to pair it with your TV. Unlike system mirroring, you can often only mirror specific media files, rather than the entire smartphone screen. This is convenient if you want to share a presentation or photos with friends without displaying messaging notifications on the big screen.
Why might AirPlay not work on older models?
AirPlay 2 technology requires specific computing power and license keys, which are not built into webOS models. For such TVs, the only solution is to use external set-top boxes (Apple TV) or third-party repeater apps.
Another option is to use the function Smart ShareAlthough it's more commonly associated with DLNA servers, it can work with iPhones using third-party players that support this standard. Launch a video file in a compatible player (such as VLC or nPlayer), press the cast button, and select your LG TV. In this case, the phone acts only as a remote control, and the stream goes directly from the router to the TV, reducing the strain on the smartphone's battery.
Using third-party apps for broadcasting
When standard tools fail, universal solutions from third-party developers come to the rescue. Applications like Replica, Cast to TV or Screen Mirroring for LG They use proprietary screen capture and data transfer algorithms. They are especially useful for streaming content from apps that block standard AirPlay (for example, some streaming services or video calls).
The principle behind these programs is simple: you install an app on your iPhone and, in some cases, a companion app on your TV (via the LG Content Store). Once paired, a virtual channel is created through which the video stream is transmitted. It's worth noting that free versions often have session time limits or contain ads.
β οΈ Attention: When using free third-party apps, carefully monitor the permissions they request. Some may require access to your local network and media library, which could potentially pose a privacy risk.
Image quality in third-party apps can vary. They often experience higher latency than native AirPlay, making them unsuitable for fast-paced games. However, they are excellent for viewing static content or web pages. Be sure to check the resolution settings in the streaming app itself.
Troubleshooting connection and latency issues
Even under ideal conditions, glitches can occur. The most common issue is that the TV doesn't appear in the list of available devices. In 90% of cases, this can be resolved by rebooting the router. Unplug the router's power cord for 10-15 seconds, then plug it back in, and wait until the network is fully loaded. You can also try rebooting your iPhone and TV.
If you see a video but the sound is missing or out of sync, check your iPhone's audio output settings. Sometimes the system "forgets" to switch the audio stream to an external device. The problem could also be caused by an antivirus program on your router or by the enabled Client Isolation feature, which prevents devices on the network from communicating with each other.
If you see the "Unable to connect" message, make sure you don't have too many background apps running on your TV. Operating System webOS The stream may not be decoded properly if the memory is full. Close unused apps by double-clicking the Home button on the LG remote.
Adjusting image and sound quality
To achieve the best results, it's important to properly configure the output settings. LG TVs often have various image enhancers enabled by default, which can introduce artifacts when displaying computer graphics from an iPhone. It's recommended to switch the picture mode to Settings β Picture β Picture Mode to the "Game" or "PC" position to disable unnecessary post-processing.
The screen refresh rate also plays a role. The iPhone can stream content at 60Hz, while some movies have a native 24fps frame rate. The TV should detect and switch modes correctly, but sometimes this results in a brief black screen. This is normal behavior when changing resolution or frame rate.
How to improve connection stability?
Place the router in a visible location, away from microwaves and baby monitors. If the distance is long, use a Wi-Fi repeater or mesh system to extend coverage without sacrificing speed.
Frequently Asked Questions (FAQ)
Is it possible to mirror a screen without the Internet, only via Wi-Fi?
Yes, AirPlay and most mirroring apps don't require internet access. It's enough for the router to create a local network (even without a connection to a provider), and for both devices to be connected to it. However, streaming video from online services (YouTube, Netflix) does require internet access.
Why is there video streaming but no sound?
Check that the volume isn't turned down on your TV or iPhone. Also, try tapping the AirPlay Audio icon in your iPhone's Control Center and making sure the LG TV is selected, not your phone's speaker. Sometimes, completely closing the app you're streaming from helps.
Do all LG models support AirPlay?
No, AirPlay 2 support is available for 2019 and newer models, as well as some updated 2018 models (B9, C9, E9, W9, Z9 series, and 2020 OLED TVs). Older models require external Apple TV boxes or third-party repeater apps.
Does screen mirroring affect iPhone battery life?
Yes, video encoding and active Wi-Fi use a significant amount of power. It's recommended to charge your iPhone during extended use, especially if you plan to watch a movie in high definition.
