Modern Apple smartphones boast powerful multimedia capabilities, but their small displays are often insufficient for comfortable movie viewing or sharing photos with friends. Fortunately, the smart TV ecosystem makes it easy to scale content. Mirroring your iPhone screen to an LG TV has become a standard feature available to owners of models released after 2018, thanks to built-in protocol support. AirPlay 2This eliminates the need to purchase additional set-top boxes or HDMI cables if both devices are on the same network.
However, the process can be complex for beginners due to the many nuances of network setup and software versions. Owners of older models LG Smart TV Problems with earlier versions of the webOS operating system haven't been overlooked either, as there are proven third-party solutions. In this article, we'll examine in detail all available methods, from native Apple capabilities to specialized apps that guarantee stable, lag-free video transmission.
Checking compatibility and preparing equipment
Before setting up, it's crucial to ensure your equipment is technically ready for wireless data transmission. The primary requirement is that your TV supports the technology. AirPlay 2, which is built into most LG models released since 2019, as well as some devices from 2018. If your TV runs on the platform webOS 4.0 and newer, the chances of having the feature built in are extremely high, but checking the model specifications never hurts.
The second and most important requirement is that both devices are on the same local network. The router must broadcast a signal at a 5 GHz frequency to ensure sufficient channel bandwidth, especially if you plan to stream high-definition video. 4K HDRIf the devices are connected to different networks (for example, one via a guest network and the other via the main network), discovery will not be possible.
⚠️ Important: Make sure that the Client Isolation feature is disabled on your router, as it often blocks communication between wireless devices within the same network.
It's also worth checking that your firmware is up to date. On your iPhone, go to Settings and check for updates. iOSOn your LG TV, you need to go to the settings menu and select the software update option to eliminate errors related to incompatibility of security protocols.
- 📱 Make sure your iPhone is running iOS 12.3 or later.
- 📺 Check your LG TV model for AirPlay 2 support in the official documentation.
- 📶 Connect both devices to the same 5GHz Wi-Fi network.
- 🔄 Update your software to the latest available versions.
Setting up built-in AirPlay on an LG TV
If your TV is a supported model, the first step is to activate the signal reception function directly in the TV menu. The interface may vary slightly depending on the version. webOS, but the logic of actions remains the same. You will need a remote control Magic Remote, which makes menu navigation much easier.
To get started, press the settings button on the remote or select the gear icon in the upper right corner of the screen. In the menu that opens, find the section for general settings or connecting external devices. This is where you'll find the switch that makes the TV visible to Apple devices.
After activating the feature, the system may prompt you to set a passcode. This is a security measure to prevent unauthorized devices from connecting to your screen. We recommend setting the passcode prompt upon first connection to control who is streaming content.
⚠️ Note: The menu interface may change after updating your TV's firmware. If you don't see the AirPlay option in the specified location, try searching through the settings or refer to the user manual for your specific model.
In some cases, manual device registration is required. If your iPhone doesn't detect the TV, try logging in to the app. HomeKit on the TV and scan the code that appears on your smartphone screen. This will create a trusted connection between the devices.
☑️ Activate AirPlay
Broadcasting via the standard iPhone menu (Screen Mirroring)
Once your TV is ready, you can begin setting up your smartphone. In iOS, the image mirroring feature is called "Screen Mirroring" or Screen MirroringIt allows you to duplicate everything that happens on your phone's display, including the desktop, games, and settings menu.
To start broadcasting, open the Control Center. On iPhone models with Face ID (without a Home button), swipe down from the upper-right corner of the screen. On models with a Home button, swipe up from the bottom. In the menu that opens, look for the icon with two overlapping rectangles.
Tap this icon, and the system will begin searching for available devices. Your LG TV should appear in the list with the corresponding name. When you select a device, a connection confirmation prompt and a four-digit code may appear on the TV screen. Enter this code on your iPhone to complete the pairing.
- 🔽 Open Control Center with a swipe, depending on your iPhone model.
- 📱 Click the "Screen Mirroring" button.
- 📺 Select your LG TV from the list of available devices.
- 🔢 Enter the confirmation code displayed on the TV screen.
If the image appears but the sound continues to play through the phone's speaker, tap the iPhone screen to bring up the controls and select the TV as the audio output device (AirPlay Audio). This will provide the full cinematic experience.
What should I do if the code doesn't arrive?
If the code doesn't appear on the TV screen, try resetting the AirPlay app in the TV settings (turn it off and then on again). Also, check if your phone is in "Do Not Disturb" mode, which sometimes blocks pop-up requests.
Using the LG TV Plus app for advanced control
For users who find the standard functions insufficient, LG offers an official application LG TV PlusThis tool turns your smartphone into an advanced remote control, allowing you not only to mirror your screen but also to transfer files and control media playback with more flexible settings.
Download the app from the App Store and launch it. The program will automatically scan the network and offer to connect to the detected TV. Once paired, a virtual remote control will appear on your smartphone screen, mimicking the functionality. Magic RemoteThis is especially convenient if the physical remote control is lost or the battery is dead.
The app's "Screen Share" feature operates using a slightly different algorithm than native AirPlay, which can help in situations where standard streaming is unreliable. The app also lets you stream photos and videos from your phone's gallery, adding them to your TV's playlist.
| Function | Standard AirPlay | LG TV Plus app |
|---|---|---|
| Screen mirroring | Yes (full) | Yes (via Screen Share) |
| Cursor control | No | Yes (Magic Mobile) |
| File transfer | Limited | Yes (photo, video, music) |
| Stability | High | Depends on the software version |
Using the official app is especially useful for older TV models that don't have built-in AirPlay support but are connected to the internet. In this case, the app acts as a bridge, streaming content via its own data transfer protocol.
Alternative methods via third-party applications
In cases where native methods don't work or the TV is an older model without AirPlay support, third-party developers come to the rescue. Apps like Replica, TV Assist or Webcast create a software emulation of the broadcast protocol, forcing the TV to receive the signal.
The principle behind these programs is simple: you install the app on your iPhone, and you may need to install a companion app on your TV (via the LG Content Store), although many modern solutions work through the TV's browser or DLNA. After launching the app on your phone, it scans the network and prompts you to select a device.
The main advantage of these solutions is the ability to stream audio in apps that block AirPlay output due to licensing restrictions (DRM). However, it's important to note that free versions often have session time limits or contain ads.
When using third-party software, it's important to monitor network load. Encoding a real-time video stream requires a stable connection. If you notice audio and video desync, try lowering the streaming quality in the app settings or moving closer to the router.
- 📲 Download a verified streaming app from the App Store.
- 📺 Make sure that a browser or the corresponding receiver app is open on your TV.
- 🔗 Select the device from the list inside the iPhone app.
- ▶️ Start the broadcast and check the image quality.
Some apps allow you to stream content directly from the clipboard or from file managers that support the DLNA protocol, which expands your multimedia experience.
Solving common connection problems and errors
Even with proper setup, technical issues may still occur. Most often, the problem lies in the network settings cache. If the TV stops detecting your iPhone or the connection keeps dropping, perform a full network reset on both devices. On iPhone, do this via "General" -> "Reset" -> "Reset Network Settings."
Another common cause is using a VPN on your smartphone. VPNs reroute traffic, causing the local discovery protocol (Bonjour/mDNS) to stop working correctly. Be sure to disable any VPN services before attempting to connect.
⚠️ Important: If you're using a dual-band router, make sure both devices are connected to the same frequency (either both to 2.4 GHz or both to 5 GHz), even if they have the same network name (SSID). Sometimes routers isolate bands from each other.
It's also worth checking your router's firewall settings. Some router-level antivirus solutions can block ports required for video streaming. Try temporarily disabling traffic filtering for diagnostic purposes.
Optimizing video and audio quality
To achieve the best image quality, it's important to consider the technical limitations of your wireless connection. Wi-Fi signals are susceptible to interference from microwave ovens, Bluetooth devices, and neighboring networks. Placing the router within direct line of sight of your TV and phone will significantly improve stability.
If you see compression artifacts or blocky images, try lowering the output resolution in your iPhone's settings (if available in the app) or switching your router to a less congested channel. For 4K movies, using the standard is highly recommended. Wi-Fi 5 (ac) or Wi-Fi 6 (ax).
The soundtrack may also require adjustment. In some cases, the sound may be delayed. LG TV settings often have an "Audio Sync" or "AV Sync" option under "Sound," which allows you to manually adjust the delay in milliseconds.
Use a high-quality router that supports AC or AX standards. Older N devices may not be able to handle high-bitrate streams, resulting in constant buffering.
Why isn't my LG TV showing up in the AirPlay list on my iPhone?
Most often, the cause is that the devices are connected to different Wi-Fi networks or client isolation is enabled on the router. Also, check if your TV's firmware requires a firmware update, as AirPlay support was added in later versions of webOS for some models.
Is it possible to stream a screen without a Wi-Fi router?
A direct Wi-Fi Direct connection between an iPhone and an LG TV for AirPlay is not supported. However, some TV models can create a hotspot to which a phone can connect, but this requires complex manual configuration and does not guarantee that the Apple protocol will work.
Is sound transmitted when using Screen Mirroring?
Yes, when using the built-in Screen Mirroring feature, audio is automatically sent to the TV. If there's no sound, check the volume settings on your iPhone and ensure the TV, not your phone, is selected as the audio output device.
Does screen mirroring affect iPhone battery life?
Yes, encoding and transmitting a video signal over Wi-Fi consumes significant power. The battery may drain faster than usual, so it's recommended to keep your phone charged or use a wireless charger during extended viewing periods.
