Modern users rarely limit themselves to viewing content on the small screen of a smartphone. They often need to share photos with friends or watch a high-definition movie on a larger display. Apple device and TV owners LG Smart TV can easily solve this problem without buying extra cables. Wireless connectivity opens up a wide range of multimedia options, turning the living room into a full-fledged entertainment center.
The basis of such interaction is a local network Wi-Fi, which unites devices into a single ecosystem. For the technology to function correctly, it's critical that both devices are on the same router subnet. In this article, we'll take a detailed look at all available streaming methods, from built-in system functions to specialized apps. You'll learn how to avoid image lag and ensure a stable data stream.
Before proceeding with settings, it's worth making sure your equipment is compatible. New TV models support the protocol. AirPlay 2 natively, which greatly simplifies the process. However, even older versions of the operating system webOS Allow you to organize your broadcast using the brand's built-in tools. We'll cover each method so you can choose the one that best suits your situation.
Preparing equipment and network
The foundation of a successful connection is a properly organized local network. Make sure your router is broadcasting at the correct frequency. 2.4 GHz or 5 GHz, and both devices are connected to this source. Users often make the mistake of connecting their phone to mobile data or a guest network, which prevents the TV from being detected.
Make sure the software is up to date on both devices. On the TV LG This can be done through the settings menu by selecting "General" and then "About TV". For a smartphone, this is relevant iOS also plays a role, as older versions may not support new media transfer protocols.
⚠️ Important: If your router supports the "Guest Network" feature, do not connect devices to it for streaming. This feature often isolates clients from each other for security reasons, and the phone simply won't see the TV in the list of available devices.
For stable transmission of high-resolution video, especially in the format 4K, it's recommended to use the 5 GHz band. It provides higher throughput and is less susceptible to interference from neighboring networks and household appliances. If the signal is weak, image artifacts or audio desynchronization may occur.
Using the built-in AirPlay 2 feature
The easiest and highest quality way to transmit images is available on televisions. LG, released after 2019. Technology AirPlay 2 built directly into the operating system webOS, which allows you to stream content without installing additional software. To get started, you need to activate this feature in your TV settings.
Go to the remote's settings menu and find the "Support" or "General" section. In the "AirPlay & HomeKit" menu, toggle the switch to "On." You may then see a code appear on the screen that you'll need to enter on your iPhone to confirm the trusted connection. This is a security measure to prevent unauthorized access to your screen.
On your iPhone, open Control Center. For models with Face ID, swipe down from the top right corner; for models with a Home button, swipe up from the bottom. Tap the Screen Mirroring icon (two rectangles). Select your screen mirroring from the list. LG Smart TVThe image will instantly appear on the big screen.
- 📱 Instant start: The broadcast starts immediately after selecting the device in the iPhone menu.
- 🔒 Safety: Option to set a password or require confirmation each time you connect.
- 🎵 Multimedia: Support for transmitting not only images, but also high-quality sound through external speakers.
- 🔄 Stability: The protocol is optimized to minimize delays when viewing video.
Streaming via the LG TV Plus app
If built-in AirPlay doesn't work for some reason or your TV model doesn't support this protocol, the official app will come to the rescue. LG TV PlusThis is a universal tool that turns your smartphone into a remote control and media center. The app is available for free in the App Store.
After installation, launch the program and wait for it to scan the network. Upon detection of the TV, the following message will appear on the screen: LG A connection permission request will appear. Accept it using the remote control. The app interface not only allows you to display photos and videos from your gallery but also broadcast your screen content in real time using the "Screen Share" feature.
It's important to note that using this method may increase the load on your phone's processor, which will drain your battery faster. Additionally, some features may require you to create an account. LG Service, although basic broadcasting is often available without it.
| Function | AirPlay 2 | LG TV Plus | Third-party applications |
|---|---|---|---|
| Picture quality | High (HD/4K) | Medium/High | Depends on the application |
| Latency | Minimum | Average | High |
| TV control | Limited | Complete | Media only |
| Required OS | iOS 12.3+ | iOS 10.0+ | Depends on the version |
Setting up SmartShare and DLNA
Technology DLNA (implemented in LG TVs as SmartShare) is a classic method of sharing media content. It's ideal for watching pre-downloaded movies or photos stored on an iPhone. Unlike screen mirroring, the phone acts as a server, sending the file for playback.
To use this method, make sure your iPhone settings allow local network access for the player app you're using. iOS's default file system access restrictions can restrict access, so installing a third-party player with DLNA support is often necessary, such as VLC for Mobile or Infuse.
In the player app, find the "Local Network" or "Devices" section. Select your LG TV from the list. This will open a file structure or video selection interface. After playing a file, playback controls (pause, rewind) remain on your smartphone, and the TV simply displays the video stream.
⚠️ Please note: The DLNA protocol does not support the transfer of DRM-protected content from streaming services (Netflix, iTunes Movies). When attempting to play such a movie, you will see a black screen with sound or an error message due to HDCP protection.
The advantage of this method is the ability to turn off the smartphone screen or use it for other tasks while watching. The video stream is processed by the TV, which saves battery life and reduces device heat.

Third-party mirroring apps
When built-in tools fail or advanced functionality is required, third-party apps come to the rescue. The leaders in this niche are Replica, TV Cast for LG And AirScreenThey use their own compression and video stream transmission algorithms, which sometimes allows for better compatibility with older TV models.
Let's look at the operating principle using a popular solution as an example. After installing the app on your iPhone and the corresponding receiver (if required) on your TV, you need to initiate the search process. Most such programs work by creating a virtual AirPlay certificate, which tricks the iPhone into thinking it's connected to a native Apple receiver.
Some applications require installation of additional software on the TV itself through the store. LG Content StoreSearch the app store on your TV, enter the app name (for example, "AirPlay" or "Screen Share"), and install it. Then follow the on-screen instructions to pair.
- 📺 Compatibility: They even work on TV models released before 2018.
- ⚙️ Flexibility: Often have settings for resolution, bitrate and screen orientation.
- 💰 Monetization: Many features may only be available in the paid version or with ads.
- 🔋 Resource intensity: They may put more strain on the smartphone's Wi-Fi module.
Why might the sound not work during broadcasting?
Often, the problem stems from a difference in the video and audio transmission protocols. Some apps only transmit the video stream, leaving the audio on the phone. Check the audio output settings in the streaming app itself or manually switch the audio output to the TV speaker in the iPhone's Control Center.
Solution and optimization
Even with proper configuration, users may encounter issues. The most common is that the TV isn't visible in the device list. In this case, try rebooting the router by completely unplugging it for 10-15 seconds. This will clear the network table cache and refresh DHCP leases.
Another common issue is audio and video desynchronization. This often occurs when the Wi-Fi signal is weak or when neighbors are congesting the channel. Try changing the broadcast channel in your router settings to a less congested one (for example, 1, 6, or 11 for 2.4 GHz). There's a wider selection of channels for the 5 GHz frequency.
If the image is choppy or low-resolution, check if power saving mode is enabled on your phone. It may be limiting Wi-Fi performance. You should also close background apps that actively use the network, such as torrents or cloud syncing apps.
⚠️ Please note: The interface of LG TVs and the iOS operating system is updated regularly. The layout of menu items, section names, and icon appearance may differ from those described in the instructions. Always refer to the interface logic and the current software version of your device.
Frequently Asked Questions (FAQ)
Is it possible to display an iPhone screen on an LG TV without a Wi-Fi router?
Yes, this is possible using Wi-Fi Direct technology, which is built into many LG models. In this case, the phone connects directly to the TV, creating its own network. However, functionality will be limited, and the phone's internet connection will not work unless mobile data is also being used.
Why is the quality worse when streaming from YouTube than on the phone itself?
You're most likely using the "Screen Mirroring" feature, not the "Cast" button within the YouTube app. Mirroring streams the video from your phone's screen, compressing it on the fly. For better quality, use the built-in Cast button (the rectangle with waves) in the YouTube app, which sends the video link directly to your TV.
The video is lagging when playing from my phone on TV. What should I do?
Wireless image transmission always introduces latency. This is critical for gaming. Try switching your router to the 5 GHz channel if it hasn't already. Also, make sure your phone isn't overheating. If latency remains high, wireless may not be suitable for fast-paced shooters or racing games.
How do I disable the code prompt every time I connect to AirPlay?
Go to your LG TV settings and navigate to "Support" -> "AirPlay & HomeKit." Find "Require Code" and change the setting to "First Time" or "Off." This will allow automatic connections in the future, but will reduce security if others have access to your network.
