Modern technologies make it easy to display content from mobile devices on the big screen, but Apple product owners often encounter issues when trying to connect their iPhone to an LG TV. Unlike Android smartphones, which often use the Miracast protocol, the Apple ecosystem is based on AirPlay, which requires specific configuration on the receiving device. If you want to enjoy videos, photos, or games on a large display without the hassle of wires, you need to set up the wireless connection correctly.
There are several proven ways to accomplish this task, from built-in iOS features to using specialized apps from the TV manufacturer. The success of the operation directly depends on the model of your TV. Smart TV and iOS operating system versions. In this article, we'll detail all available methods, troubleshoot common errors, and help you enjoy high-quality multimedia.
Before you begin setup, make sure both devices – your smartphone and TV – are connected to the same network. Wi-FiThis is a fundamental requirement for most wireless data transfer protocols to work. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, make sure both devices can see each other, even if they're connected to different bands of the same network.
Equipment preparation and compatibility testing
The first step is to verify the technical specifications of your equipment. Not all LG TVs support the native AirPlay 2 protocol. This feature became standard on models released in 2019 and later, as well as on some updated versions from 2018. If you have an older model, you'll have to rely on third-party apps or external set-top boxes.
Check the software version on your iPhone. For stable screen mirroring, it's recommended to use iOS 12.3 or later, although modern versions offer better stability and lower latency. It's also worth making sure your LG TV has the latest firmware version. webOS.
⚠️ Please note: The menu interface on LG TVs may differ depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). The layout of menu items may change after updates, so always consult the latest user manual for your specific model.
To connect, you'll need a stable wireless signal. If the router is far from your TV or smartphone, streaming quality may suffer: the image will stutter and the sound will be intermittent. Ideally, the distance between the devices and the router should be no more than 10 meters, with no obstructions such as walls.
Using the built-in AirPlay 2 feature
The easiest and highest-quality way to stream images is to use native AirPlay 2 support, which is built directly into the operating system of LG TVs. You don't need to install any additional apps on your iPhone if your TV is a supported model. This method ensures minimal latency and high picture quality.
To activate the function, take the remote control and press the button Home (house). Find the card in the bottom menu. Apple AirPlay or go to Settings → Connection → Apple AirPlay and HomeKitMake sure the switch is in the "On" position. If the card isn't on the home screen, try searching for it in the "My Apps" section or downloading it from the LG Content Store.
After activation, a code may appear on the TV screen. Pick up your iPhone, unlock it, and make sure Wi-Fi is turned on. Open the content you want to cast (video, photo), or use the "Screen Mirroring" feature. Select your device from the list of available devices. LG TVIf the system asks for a code, enter the number combination displayed on the TV into the field on your smartphone.
- 📱 Open Control Center on your iPhone (swipe down from the top-right corner or up from the bottom on older models).
- 📺 Click on the "Screen Mirroring" icon (two rectangles).
- 📡 Select the name of your LG TV from the list of available devices.
- 🔢 Enter the confirmation code if it appears on the TV screen.
It's important to note that when using AirPlay 2, the smartphone and TV must be on the same subnet. If you have a complex network infrastructure with multiple routers or a mesh system, make sure Client Isolation is disabled, otherwise the devices will not be able to "see" each other for video streaming.
Streaming via the LG TV Plus app
If the built-in AirPlay doesn't work for some reason or your TV model doesn't officially support this feature, you can use the proprietary app. LG TV PlusThis is the manufacturer's official solution that allows you to control your TV and stream media content from iOS mobile devices.
First, download the app from the App Store. Once installed, launch it on your iPhone. It will automatically search for available LG TVs on your Wi-Fi network. Select your TV from the list. You may see a connection permission prompt on the TV screen—confirm it with your remote.
In the app interface, navigate to the section for media files or screen. Here, you can select photos or videos from your iPhone gallery and send them to the big screen. However, keep in mind that full-screen mirroring functionality in this app may be limited compared to native AirPlay.
| Characteristic | AirPlay 2 (Native) | LG TV Plus (App) | Third-party applications |
|---|---|---|---|
| Image quality | High (HD/4K) | Medium/High | Depends on the application |
| Latency | Minimum | Average | High |
| Stability | High | Average | Low/Medium |
| Required actions | Device selection only | Installing the application | Installation and configuration |
Using the official app is especially useful if you want to do more than just mirror your screen, but also control playback of files stored on your smartphone. It's a convenient way to show friends photos from your last party on a big screen without the hassle of wires.
Alternative methods via third-party applications
Owners of older LG TV models that lack built-in AirPlay support and are unable to work with newer app versions can use third-party solutions. The App Store offers numerous intermediary apps that emulate signal reception on the TV.
One popular solution is to install a receiver app directly on the LG TV (if the LG Content Store allows it) or use a PC as a bridge. However, more often than not, an app like TV Cast or similar, and on iPhone - a companion app from the same developer.
These programs work by creating a local communication channel. You open the app on your TV, and it displays an IP address or QR code. On your iPhone, you enter this information or scan the code, which opens a transmission channel. Videos or photos are sent through this channel.
⚠️ Warning: Third-party apps often contain ads or require a paid subscription to unlock Full HD quality. Be careful when granting access to your local network to unknown developers.
There's also a browser-based method for casting. Some modern Smart TV browsers allow you to open web pages. You can upload a photo to a cloud service or social network on your iPhone, then open the same website in your LG TV's built-in browser. This isn't full-fledged screen casting, but it's a quick way to share content.
Why might third-party apps be slow?
Third-party apps often use software encoding of the video stream on the phone's processor, which creates a load and increases latency, unlike the hardware encoding in native AirPlay.
Troubleshooting connection and buffering issues
Even with proper setup, users may encounter issues: the image flickers, the audio lags behind the video, or the connection constantly drops. Most often, this is due to congestion in the wireless channel or a weak signal.
Try switching your router to a channel with less congestion. If your router is dual-band, make sure both your iPhone and LG TV are connected to the 5 GHz network. This band provides higher data transfer speeds, which is crucial for streaming high-definition video, although it has a shorter range.
Another common issue is outdated DNS. Try updating your TV and router's network settings to use public DNS servers, such as Google's (8.8.8.8) or Cloudflare (1.1.1.1). This can improve the speed of establishing a connection between devices.
- 🔄 Restart your router by unplugging it from the power outlet for 10 seconds.
- 📶 Move closer to the router while broadcasting to check the signal quality.
- 📵 Disable your iPhone's VPN if it's enabled—it often blocks local data transfers.
- 🛠 Reset your TV's network settings using the menu
Settings → Network → Advanced Settings → Edit.
If the issue persists only with one specific iPhone app (for example, YouTube), try updating the app itself. Sometimes, bugs in the program code prevent the casting protocol from being initiated correctly. In extreme cases, deleting and reinstalling the app may resolve the issue.
☑️ Connection diagnostics
Streaming content from specific apps
Many popular services, such as YouTube, Netflix, Instagram, and TikTok, have a built-in casting feature that works independently of the system's AirPlay. This is often a more convenient option, as it allows you to use your phone for other tasks while watching a video on your TV.
In the YouTube app, simply tap the streaming icon (the rectangle with waves) in the corner of the video and select your LG TV. The TV will automatically find the video online and play it, using your phone only as a remote. This reduces the load on your smartphone's battery and saves data.
Instagram or TikTok may not have a live screencast feature, so you'll have to use the system's "Screen Mirroring" feature. However, some videos in these apps have their own "Cast" button. If the content is copyrighted, the system's broadcast may be blocked (a black screen with sound will be displayed), requiring you to find a workaround or use the browser version.
It is important to understand the difference between DLNA And AirPlayMany older apps on LG TVs use DLNA to play files from your phone. This works well for photos and videos, but isn't suitable for dynamic content like games or web browsing, which require real-time image mirroring.
Frequently Asked Questions (FAQ)
Why isn't my LG TV visible in the AirPlay list on my iPhone?
Most likely, the devices are connected to different Wi-Fi networks (for example, one to a guest network, the other to the main network) or to different frequency bands with isolation. Also, check if "Guest Network" mode is enabled on the router, which prevents devices from seeing each other. Make sure AirPlay is enabled on your TV in the settings.
Is it possible to mirror an iPhone's screen to an old LG TV without Smart features?
Directly over Wi-Fi – no, as the TV doesn't have an operating system to process the signal. You'll need to purchase an external set-top box with AirPlay support (such as an Apple TV or an Android box with the appropriate software) and connect it via HDMI.
Why is there no sound or is it interrupted during broadcasting?
Check your iPhone's sound settings: make sure silent mode isn't enabled or the media volume isn't turned down. Wi-Fi congestion could also be the issue. Try disabling Bluetooth on your phone, as it operates on the same 2.4 GHz frequency and can cause interference.
Does screencasting affect internet speed?
Yes, streaming high-definition video (especially 4K) consumes a significant portion of your local network's bandwidth. If someone is simultaneously downloading large files or playing online games, the stream quality may degrade.
