There are several proven methods for achieving this, each with its own features and advantages. In this article, we'll cover all the options in detail, from built-in Apple features to specialized apps.
You don't need extensive networking knowledge to successfully implement your plans. All you need is for both devices to be on the same local network and in good working order. We'll cover setup details, potential pairing issues, and solutions so you can enjoy high-quality content without lag or image artifacts.
Network requirements and equipment preparation
Before setting up your broadcast, you need to ensure that the basic technical requirements are met. The foundation of a wireless connection is stable operation. Wi-Fi routerBoth devices—the smartphone and the TV—must be connected to the same wireless network. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks, make sure the devices aren't on different subnets with client isolation.
It is important to check that your software is up to date. iPhone 11 the latest available version must be installed iOS, as Apple regularly updates AirPlay security protocols and features. The situation is similar with TVs. LG: in the menu Settings → All settings → Support → Software update It's worth checking for new versions firmwareOutdated software often causes devices to simply "not see" each other in the list of available devices.

Signal quality plays a critical role. If the TV is located far from the router or the signal is weakened by walls, you may experience lag or audio and video desynchronization. Ideally, the distance between the router and LG Smart TV should be minimal, and the channel frequency should be the least loaded with neighboring networks.
Using built-in AirPlay 2 on LG TVs
The most preferable and high-quality method is to use technology AirPlay 2. Starting with certain 2018-2019 and newer models, the company LG implemented native support for this protocol. This means no third-party apps or complicated settings are required for connection—everything works out of the box.
To activate the function, take the remote control LG and press the button Home (house). At the bottom of the screen, find the "LG Connection" panel or go directly to the section Settings → Support → AirPlayHere, you need to toggle the slider to the "On" position. Once activated, the TV will begin broadcasting its availability to Apple devices.

- 🔄 Click the "Screen Mirroring" button (two rectangles) and select your LG TV from the list.
- 🔢 If a four-digit code appears on the TV screen, enter it on your smartphone screen to confirm.
After successful pairing, the image on the screen iPhone will instantly appear on your TV. You can flip your smartphone horizontally, and the image will expand to fill the entire screen. AirPlay 2 technology also enables multi-channel audio, creating an immersive movie experience.
It's worth noting that the AirPlay feature on LG TVs not only allows you to mirror your screen but also stream content directly from apps. For example, in YouTube or Netflix, you can tap the cast icon and select the TV, allowing you to use your smartphone for other tasks without interrupting your viewing experience.

It's available as a free download in the App Store.
After installing the app, launch it and follow the on-screen instructions. The program will automatically scan the network and find your TV. To complete the connection, you will need to enter the code displayed on the TV screen into the app interface. iPhone 11This action will create a secure tunnel for data transfer.
Unlike simple screen mirroring, LG TV Plus allows you to selectively share files. You can open your photo or video gallery in the app, select the desired file, and send it to the big screen. This is especially convenient when you want to share a specific photo with friends without broadcasting messaging notifications or phone calls.

Alternative methods: third-party apps and Screen Share
In situations where built-in tools don't work or additional features are required (for example, screen recording during broadcasting), you can turn to third-party solutions. The App Store offers a variety of intermediary apps, such as Replica, TV Cast for LG or Web Video Caster.
The principle of their work is similar: you install the application on iPhone, and on the TV (via the LG Content Store) you often need to install a companion app or simply run the built-in function Screen ShareAfter this, the devices are connected via a local network.
The function deserves special attention Screen Share (Miracast), which is built into LG TVs. Although iOS While Miracast doesn't natively support the protocol, many third-party apps emulate it. This allows you to connect your iPhone to TVs that don't support AirPlay.
⚠️ Please note: Third-party free apps often contain ads or have session time limits. Carefully review the terms of use before installing to avoid unexpected subscriptions.
When using third-party software, it's important to pay attention to signal lag. While it's not critical for viewing static photos, when playing fast-paced games or videos, lag can range from 1 to 3 seconds, which can be annoying. To minimize lag, close background apps on your iPhone.
Wired connection via Lightning-to-HDMI adapter
Despite the topic of this article being about WiFi, you can't ignore the wired method, which is the most stable. If your wireless network is overloaded or the signal quality is poor, using an adapter Lightning to Digital AV will be a lifesaver. This method guarantees the transmission of images in Full HD or 4K format without compression or delays.
To implement this method, you will need the adapter itself (official Apple or MFi-certified) and a regular HDMI cable. Plug one end of the cable into the adapter connected to the iPhone 11, and the other into an available HDMI port on the LG TV. Then, in the TV menu (Input or the button with an arrow in a square) you need to select the appropriate signal source.
The main advantage of this method is its independence from internet speed and Wi-Fi network conditions. The image is transmitted directly, making it ideal for games where every millisecond counts, or for presentations where connection interruptions are unacceptable. Furthermore, the adapter can often simultaneously charge a device.
| Parameter | AirPlay (WiFi) | Lightning-HDMI (Cable) |
|---|---|---|
| Stability | Depends on the router | Maximum |
| Latency | Present (0.5-2 sec) | Absent |
| Image quality | Compressed (network dependent) | Original (lossless) |
| Mobility | High (can walk) | Limited by cable length |
☑️ Check before connecting the cable
When choosing an adapter, beware of cheap Chinese-made alternatives that are not MFi (Made for iPhone) certified. They may perform poorly, display black and white images, or be blocked by iOS updates. A genuine Apple adapter is more expensive but guarantees compatibility.
Solving common connection problems and errors
Even if you follow all the instructions, technical difficulties may arise. One common issue is that the TV doesn't appear in the list of available devices. In this case, try restarting both devices: completely turn off the TV (don't just put it to sleep, but unplug it for 10 seconds) and restart your iPhone.
Another common cause is a connection being blocked by the router's antivirus software or firewall settings. Make sure the "AP Isolation" feature, which prevents devices within the network from communicating with each other, isn't enabled in your router's settings.
What to do if there is sound but no picture?
This is a common codec issue. Try changing the video format in the app you're streaming from or updating the LG TV Plus app. Switching your router's frequency from 5 GHz to 2.4 GHz and back again may also help.
If the image is choppy or the video is constantly buffering, reduce the stream quality in the source app's settings. Also, check if the channel is being overloaded by other devices (for example, someone downloading torrents or watching 4K video on another TV).
⚠️ Please note: LG TV interfaces and iOS versions are constantly being updated. The layout of menu items may differ slightly from that described in the instructions. Always refer to the latest user manual on the manufacturer's official website.
In case of persistent errors (constant failures), reset the network settings on the iPhone (Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings). This will delete saved Wi-Fi passwords, but often solves problems connecting to peripherals.
