Modern technologies make it easy to integrate devices into a single ecosystem, turning a smartphone into a powerful multimedia control panel. Apple device owners often need to display photos, videos, or presentations on a large screen, and connecting a cable isn't always convenient. Fortunately, wireless data transfer protocols allow you to stream content from iPhone on TVs LG Smart TV almost instantly.
The basis for such synchronization is the home network. Wi-Fi, which must be stable and cover both devices. There are several proven methods for achieving this, ranging from native operating system functions to specialized software. The choice of a specific method often depends on your TV model and the version of the operating system installed. webOS.
In this article, we'll take a detailed look at all available connection options, address common errors, and offer solutions for complex situations. Whether you have a new flagship or a previous model, you'll be able to find a working solution for displaying images. The key is to follow the instructions and carefully check your network settings.
Technical requirements and equipment preparation
Before you begin setting up the broadcast, you need to make sure your equipment meets the minimum technical requirements. A fundamental requirement is that your TV has LG support functions Smart TV and a wireless communication module. Without internet access or a local network, data transmission over the air is fundamentally impossible.
The second critical requirement is that both devices must be on the same subnet. This means that iPhone and TV LG must be connected to the same router. If you have a dual-band router broadcasting both 2.4 GHz and 5 GHz networks, make sure the devices can see each other, although modern routers usually combine them into a single logical network.
⚠️ Attention: If your router is configured in AP Isolation mode, devices will be unable to communicate even when connected to the same access point. Check your router's security settings if the connection fails.
It's also worth checking that the software is up to date. On TVs LG with the operating system webOS version 4.0 and higher protocol support AirPlay 2 built-in by default. Older models may require installing additional apps or using alternative data transfer methods, such as DLNA.
☑️ Check before connection
Using native AirPlay 2 on LG
The highest quality and most stable image transmission method is available to TV owners LG with technology support AirPlay 2This protocol, developed by Apple, allows you to stream videos, photos, and even your smartphone's screen in high resolution with minimal latency. You don't need to download anything to get started, as the feature is already built into the system.
The first step is to activate the signal receiver on your TV. To do this, take the remote control. LG and go to the main settings menu. Find the section responsible for connecting external devices, which varies in different versions. webOS may be called differently, but always contains the word "Connection" or "Connection".
The sequence of actions on the remote control is as follows:
- 📺 Click the button
Settings(gear) on the remote control. - 🔗 Go to the menu
GeneralorConnection. - 🍎 Select an item
Apple AirPlay and HomeKit. - ✅ Make sure the function switch is in the on position
On.
After activating the feature, a confirmation code may appear on the TV screen. Now take your iPhone, open the Control Center (swipe down from the top right corner on new models or swipe up on older models) and tap the icon Screen mirroringSelect your TV from the list of available devices. LGIf prompted, enter the code displayed on the TV screen.
What to do if AirPlay isn't working?
Make sure your TV has the latest webOS firmware version. Go to Settings → Support → Software Update. Also, try rebooting your router, as temporary IP address errors can block device detection.
Streaming via the LG TV Plus app
If for some reason native AirPlay If it doesn't work or your TV model doesn't support this protocol, you can use the manufacturer's official app. LG TV Plus (formerly known as LG Remote) provides advanced control capabilities and allows you to stream media content stored on your smartphone.
To implement this method, you will need to download the application from App StoreAfter installation, launch the app and follow the on-screen instructions to pair with your TV. The app will automatically scan the network and offer a list of available devices. LG Smart TV.
The app's functionality allows you to not only control the TV channel but also display photos and videos from your gallery. However, it's worth noting that this method often works as DLNA- client, meaning it streams the file for playback rather than mirroring the screen in real time. This means you won't be able to display the game interface or browser.
| Characteristic | AirPlay 2 | LG TV Plus | Third-party applications |
|---|---|---|---|
| Transmission type | Miroring (screen) | Media files | Miroring / Files |
| Delay | Minimum | Absent | Average |
| Quality | High (HD/4K) | Original file | Depends on the codec |
| Stability | High | Average | Different |
Alternative streaming apps
In situations where standard tools fail, third-party developers come to the rescue. App Store There are many applications that use the protocols Cast And DLNA for image transmission. Popular solutions include Replica, TV Cast for LG And Web Video Caster.
These applications often have more flexible codec settings and can pass through audio even in cases where system limitations iOS Block the audio stream. They typically work by creating a local server or using screencasting technology to transmit the video stream to the TV's built-in browser or a dedicated receiver.
When choosing third-party software, pay attention to the presence of ads and paid subscriptions. Free versions often have session time or image quality limitations. Additionally, some apps may require installing a companion app from the store on the TV itself. LG Content Store.
- 📲 Replica: Allows you to duplicate your screen without delays and supports sound.
- 🎬 TV Cast: Specializes in sending videos from websites directly to TV.
- 🌐 Web Video Caster: Can recognize video streams on pages and send them to DLNA devices.
Using such programs can be an excellent solution for older TV models, where support for modern standards is limited. However, remember that stability depends entirely on the developer's code optimization.
Setting up DLNA and media servers
Protocol DLNA (Digital Living Network Alliance) is a universal standard for sharing multimedia content within a home network. Unlike mirroring, it doesn't broadcast the screen image, but allows the TV LG directly read and play files from memory iPhone.
To implement this scheme, a media server app must be running on the iPhone. The built-in Photos or Videos apps in iOS don't function as a server by default, so third-party software will be required, such as VLC for Mobile or nPlayerThese applications create an access point through which the TV sees the media library.
The algorithm of actions is as follows:
- Install a media player with DLNA support on iPhone.
- Enable the "Wi-Fi Sharing" or "DLNA Server" function in the app settings.
- On TV LG launch the application
Smart ShareorMedia player. - In the list of devices, select your phone and open the folder with videos or photos.
⚠️ Attention: When using DLNA, the video file format must be supported by the TV's codecs. If the file doesn't open, the TV may lack the codecs to decode it, and conversion will be required.
This method is ideal for watching downloaded movies or TV series in high bitrates, since the decoding load falls on the TV's processor, not the smartphone's. iPhone At the same time, it is used much more economically than with active miroring.
Solution and troubleshooting
Even if you follow all the instructions, technical difficulties may arise. The most common problem is that the TV doesn't detect iPhone in the list of available devices. In 90% of cases, this is due to the devices being on different subnets or having guest Wi-Fi mode enabled, which isolates clients from each other.
Another possible cause could be outdated router or TV firmware. Manufacturers regularly release updates that fix communication protocol errors. Check for updates in the section Support → Software Update in the TV menu LG.
If the image is broadcast but is choppy or of poor quality:
- 📉 Bring the devices closer to the router.
- 📡 Switch to the 5 GHz band if your router and devices support it.
- 🔄 Restart your router, phone, and TV (unplug them completely for 10 seconds).
It is also worth considering that some content-protected videos (DRM) from streaming services may block image output to external displays through third-party applications, but should work through the native AirPlay.
Why is there no sound when broadcasting video?
Lack of sound is often due to specific app settings on the iPhone or protocol limitations. Make sure "TV and iPhone" or simply "TV" mode is selected in AirPlay settings. Some third-party apps require you to manually enable audio streaming in the connection settings.
Is it possible to connect an iPhone to an LG without Wi-Fi?
Without a Wi-Fi network, wireless connection is impossible. However, you can use a wired connection via a Lightning to HDMI adapter (or USB-C to HDMI for newer models). This will provide the most stable picture without lag, but it requires a cable and limits your mobility.
My LG TV isn't showing up in my iPhone's Control Center. What should I do?
Check that AirPlay is enabled on the TV itself (Settings → General → AirPlay). Make sure Bluetooth is enabled on both devices, as it's used for the initial handshake. Also, try temporarily disabling the VPN on your phone, if it's active.
What is the maximum latency when using AirPlay?
When using native AirPlay 2, latency is typically less than 100 milliseconds, which is unnoticeable for video playback. However, when using third-party apps or on a noisy Wi-Fi network, latency can increase to 1-2 seconds, making fast-paced games challenging.
