Modern multimedia systems allow you to transform your living room into a real cinema using just a smartphone and a smart TV. Apple ecosystem owners often face the desire to display high-quality images from iPhone on a large display to watch a movie in 4K or show photos to friends. Wireless data transfer technology via Wi-Fi makes this process as simple as possible, eliminating the need for unnecessary wires and adapters.
Company LG Electronics has been actively implementing protocol support for several years now AirPlay 2 to their smart TVs, allowing iOS users direct integration without installing third-party software. However, despite the stated simplicity, syncing devices may require understanding the nuances of local network settings and software versions. In this article, we'll cover all available connection methods in detail, from native functions to specialized apps.
The quality of your wireless streaming directly depends on the signal stability and bandwidth of your router. If you plan to stream heavy, high-bitrate content, make sure both devices are within a strong signal range. Proper network configuration WiFi — this is the foundation without which even the most advanced video transmission technologies will operate with delays or artifacts.
Technical requirements and equipment preparation
Before you begin setting up, you need to make sure that your hardware meets the minimum requirements for the feature to work correctly. Screen MirroringNot all LG TV models support Apple's native protocol, so the first step should always be checking your specific model's compatibility with the technology. AirPlay 2This feature is typically found on OLED, NanoCell, and UHD TVs released in 2019 and later that run on the webOS platform.
A critical requirement is that the smartphone and TV are on the same wireless network. If your router broadcasts two different networks (for example, 2.4 GHz and 5 GHz) with different names, the devices must be connected to one of them. Separating the frequency bands may create the illusion of a connection, but no actual data transfer will occur between the devices.
⚠️ Note: Some corporate or guest WiFi networks have client isolation, which prevents devices from seeing each other. In these conditions, displaying an image using standard methods will not work.
It's also worth checking that the software on both devices is up to date. On an iPhone, this can be done through the iOS update settings, and on an LG TV, through the menu. Settings → All settings → Support → Software updateOutdated firmware versions often contain errors in network communication modules, which are fixed by developers in new patches.
Setting up AirPlay 2 on an LG TV
Function AirPlay On LG TVs, this feature is often disabled by default or requires manual activation upon first connection. To enable this option, take the remote control and press the settings button (gear icon). Go to Support, where you will find the item Apple AirPlay.
In the menu that opens, toggle the switch to the "On" position. Important security settings are also available here, such as requiring a code each time you connect or using a password only the first time you pair. For home use, it's more convenient to select "No code required" or "First time only" to avoid entering numbers each time.
- 📺 Go to the TV's main menu and select the settings section.
- 📡 Go to the "Support" or "General" subsection, depending on your webOS version.
- 🍏 Find the line "Apple AirPlay" and activate the slider.
- 🔒 Customize security settings according to your preferences.
Once enabled, a message may appear on the TV screen indicating that the device is ready to connect. If the feature was previously enabled, the TV will automatically search for Apple devices on the network. In some cases, you may need to restart the TV after enabling the feature to ensure network services update correctly.
Mirror your iPhone's screen using Control Center
The fastest and most reliable way to display an image is to use the built-in iOS functionality called Screen mirroringThis method broadcasts absolutely everything that happens on the smartphone's display, allowing you to demonstrate games, presentations, or a browser. To get started, unlock your iPhone and open Control center.
On models with Face ID, swipe down from the top-right corner of the screen, and on models with a Home button, swipe up from the bottom edge. Look for the icon with two intersecting rectangles. Tap it, and the system will begin searching for available devices on the Wi-Fi network.
Select your LG TV from the list that appears. If a four-digit code appears on the TV screen, enter it on your smartphone. After successful authorization, the image from your iPhone will be mirrored on the big screen. To exit mirroring mode, tap the icon in Control Center again and select "Stop Mirroring."
☑️ Pre-broadcast check
Please note that when broadcasting the entire screen, the aspect ratio may not match the TV format. In this case, black bars may appear on the sides of the image. This is normal system behavior, as iPhone preserves the original matrix resolution to avoid image distortion.
Using the LG TV Plus app and other alternatives
In situations where native AirPlay is unstable or missing on your TV model, the official app comes to the rescue. LG TV PlusIt's available in the App Store and offers advanced control features, including photo and video transfer from your gallery. After installing the app, you'll need to complete the pairing process by scanning the QR code on the TV screen.
The app interface allows you to select content from your device's local storage or stream videos from supported cloud storage services. Unlike full screen mirroring, streaming through the app often provides more stable video playback, as it uses an optimized media transfer protocol.
| Method | Image quality | Delay | Sound |
|---|---|---|---|
| AirPlay 2 | High (up to 4K) | Minimum | Synchronized |
| LG TV Plus | Medium/High | Average | Synchronized |
| DLNA (Photo/Video) | Depends on the file | Low | Synchronized |
| Third-party apps | Miscellaneous | High | Often without sound |
There are also third-party repeater apps, such as Replica or LetsView, which can be useful for older TV models. However, they often require installing additional software on the TV itself or using a computer as an intermediary, which complicates the setup.
⚠️ Note: Third-party free streaming apps often contain intrusive ads or have session time limits. Official methods are preferred.
Stream from YouTube, Netflix, and other apps
The function deserves special attention Google Cast (Chromecast built-in), which is built into many modern LG TVs. Popular video services like YouTube, Netflix, Hulu, and others use this protocol for direct streaming. In this case, the phone acts only as a remote control, while the video stream is transmitted directly from the server to the TV via WiFi.
To use this method, open an app (such as YouTube) on your iPhone. Tap the cast icon (the rectangle with waves), which is usually located in the top corner of the interface. Select your LG TV from the list. The video will start playing on the big screen, and you can use your phone for other tasks or even turn off the lock screen.
Why does video lag when streaming from a browser?
When broadcasting a browser tab (Chrome/Safari), the load falls on the phone's processor, which encodes the video stream in real time. This requires significant resources and a stable connection, unlike direct broadcasting via the app API.
The advantage of this approach is that video quality is automatically adjusted based on internet speed, significantly saving battery life. Furthermore, an incoming call will not interrupt playback on the TV, as is the case with full screen mirroring.
Diagnosing problems and troubleshooting
Even with proper configuration, users may encounter issues such as audio and video desynchronization, intermittent connection drops, or the device not appearing in the list at all. The first step is to reboot the router, as prolonged uninterrupted operation can cause the network modules' memory buffer to overflow.
If the TV no longer sees the iPhone, try going to the iPhone on your smartphone. Settings → General → AirPlay and Handoff and forcefully disable and then re-enable the feature. It's also worth checking whether your router has a speed limit for certain devices or whether "Guest Network" mode is enabled, which isolates devices from each other.
- 🔄 Restart your router, TV, and smartphone simultaneously.
- 📶 Make sure the devices are not too far apart.
- 🛡️ Check your antivirus or firewall settings on your router.
- 📲 Update the app you are using to broadcast.
If all else fails, you can reset your iPhone's network settings. Please note that this will delete all saved WiFi passwords, so you'll have to re-enter them. This often helps resolve software conflicts in the operating system's network drivers.
Why isn't my LG TV showing up in the AirPlay list?
Most often, the problem stems from the devices being connected to different subnets (for example, one to a guest network and the other to the main network). It's also worth checking whether your router's antivirus software has blocked the Bonjour protocol, which is necessary for detecting Apple devices.
Is it possible to display a screen on a TV without WiFi?
AirPlay requires a WiFi network to transmit the video stream. Without WiFi, only wired streaming via a Lightning to HDMI adapter is possible, but this is no longer a wireless connection.
Why is there no sound on the TV during broadcasting?
Check the sound settings in Control Center on your iPhone. Make sure the audio output is directed to your LG TV, not your phone's speaker or connected Bluetooth headphones. Sometimes, simply switching the audio source in the app helps.
Does broadcasting affect internet speed?
Yes, transmitting a high-definition video stream (4K HDR) consumes a significant portion of your bandwidth. If someone online starts downloading large files or playing online games, the picture quality on your TV may degrade.
