Apple smartphone owners often face the need to stream content from a small screen to a larger one. Connection iPhone to the TV LG Wi-Fi gives you access to high-definition movies, photos, and presentations without the hassle of wires. Modern technology makes this possible in minutes using the operating system's built-in features. iOS and platforms webOS.
The main tool for this process is technology AirPlay 2, which is supported by most new models from the South Korean manufacturer. However, even if your TV is several years old and doesn't natively support the Apple protocol, there are alternative methods, such as Screen Share or third-party apps. Understanding the differences between these methods will help you choose the best option for your specific situation.
It's important to note that connection stability directly depends on the quality of your wireless network. Before beginning setup, ensure both devices are within range of the router's signal. This is a basic requirement, and ignoring it often results in image lag or connection interruptions while watching.
Checking compatibility and preparing equipment
The first step is to verify the technical specifications of your equipment. Not all models LG Smart TV support Apple's direct data transfer protocol. Native support is usually AirPlay 2 present in TVs released after 2018 that run on webOS 4.0 and newer. If you have an older model, you'll have to rely on the Screen Share (Miracast), which is also built into the system, but works according to a different algorithm.
A critical requirement is that the devices be on the same network. The router must broadcast a signal on a frequency supported by both devices. Users often encounter the problem when a phone is connected to a guest Wi-Fi network or mobile data, while the TV is connected to the main home channel. In this situation, the devices cannot be detected.
⚠️ Attention: Some routers have an AP Isolation feature that prevents devices on the same network from seeing each other. If your TV can't see your phone, check your router settings and disable this feature.
It's also worth making sure that the software on both devices is updated to the latest version. On TVs LG This is done through the settings menu, and in iPhone — via the iOS update section. Older firmware versions may contain bugs that block broadcast protocols.
☑️ Preparing for connection
To check your TV model and firmware version, follow this path Settings → All settings → General → About TVHere you'll find complete compatibility information. If the model supports AirPlay, the corresponding icon will be listed in the list of supported features.
AirPlay Method 2: Native Apple and LG Integration
The highest quality method of transmitting images and sound is provided by technology AirPlay 2It provides high stability and allows you to stream content even when your smartphone's screen is off. To get started, you need to activate the feature on the TV itself. Go to the main menu and find the app. Apple AirPlay or an item in the connection settings.
After activation, a code or a message about waiting for connection will appear on the TV screen. iPhone Open Control Center (swipe down from the top right corner or up from the bottom, depending on your model). Tap the Screen Mirroring icon and select your TV. LG from the list of available devices.
- 📱 Enter the code displayed on your TV screen into the field on your iPhone to confirm the pairing.
- 📺 Select "Audio Only" or "Mirroring" mode if the system offers options.
- 🔒 Adjust privacy settings to allow connections only to devices on this network.
- 🎬 Start a video in the app and it will automatically switch to the big screen.
If the connection is established, but the image is slow, try reducing the network load. Protocol AirPlay sensitive to interference. Also, make sure there are no background applications running on the TV that could consume processor resources.
Why is AirPlay 2 better than Miracast?
AirPlay 2 uses lossless buffering and compression, and allows you to control playback from your phone without interrupting the stream, unlike standard screen mirroring.
A key advantage is the ability to use your phone as a remote control. You can pause videos, adjust the volume, and rewind content directly from your smartphone. The system automatically adjusts the video resolution to the capabilities of your TV.
Using Screen Share on older models
If your TV LG doesn't support native AirPlay, but technology comes to the rescue Screen Share, based on the Miracast standard. This method enables full screen mirroring, meaning everything that's happening on the iPhone display, including notifications and the home screen, is displayed on the TV.
To start the process on your TV, you need to open the application Screen ShareIt's usually located at the top of the startup menu or in the additional apps folder. After startup, the TV will enter connection standby mode and display the device name.
| Parameter | AirPlay 2 | Screen Share (Miracast) |
|---|---|---|
| Image quality | High (up to 4K HDR) | Average (depending on signal) |
| Latency | Minimum | Noticeable |
| Work in the background | Possible | The screen should be lit. |
| Sound | Separate channel | As part of the video stream |
On iPhone, this feature is implemented through the same Control Center. However, since iOS doesn't natively support Miracast for all apps, the system may require third-party software or may experience instability with some DRM-protected content.
⚠️ Attention: Using Screen Share drains your iPhone's battery significantly faster, as the screen must be constantly lit and the processor must actively encode the video stream. It's recommended to keep your phone close to the charger.
In some cases, when connecting via Screen Share, the image may not scale to the full screen, remaining centered with black borders. To correct this, use the TV remote. LG, by clicking the image format change button (often labeled as P:Size or Aspect Ratio) and selecting the "Original" or "16:9" mode.
Third-party media streaming apps
When built-in methods don't meet your requirements or don't work correctly, you can use specialized software. Media server apps allow you to stream videos, photos, and music from your iPhone to your TV. LG via a local Wi-Fi network using the protocol DLNA or your own algorithms.
One of the most popular solutions is the application LG TV Plus (or its newer version LG ThinQ). It turns your smartphone into an advanced remote control and allows you to transfer files from your gallery. Universal players, such as VLC for Mobile or Web Video Cast.
The workflow for these apps is usually the same: launch the app on your phone, wait for the TV to be detected in the list of available devices, and select a file to play. The video stream is transmitted directly from the phone or via a link to the server.
- 📂 File manager: Allows you to browse your phone's folders and select any video format.
- 🎞️ Codec support: Third-party players are often "omnivorous" and play files that the built-in LG player cannot read.
- 🌐 Online video: Many applications can capture a video stream from the browser and send it to TV.
Using third-party software is especially useful if you want to play a video file in a format that your TV's native player doesn't understand. In this case, the iPhone's powerful processor handles the decoding, and the final stream is sent to the TV.
Streaming content from specific apps
Many popular streaming services such as YouTube, Netflix, IVi or Okko, have a built-in Cast function. This eliminates the need for mirroring on the phone's processor and simply transmits a link to the content to the TV, which then downloads it automatically.
To activate this feature, open the app on your iPhone and look for the casting icon (the rectangle with waves in the corner). Tapping it will display a list of available devices. Select yours. LG TVIt's important that your phone and TV app accounts (if authorization is required) are synchronized.
This method is the most energy-efficient. The phone acts only as a remote control. Picture quality is the highest possible, as the TV decodes the stream itself, using its own resources.
If the Cast icon doesn't appear, check that Bluetooth is enabled on your iPhone. Some devices use Bluetooth Low Energy for the initial handshake before transmitting data over Wi-Fi. Also, make sure the Cast app is running or installed on your TV.
Troubleshooting and diagnostics
Even with proper setup, glitches can still occur. The most common issue is "The TV doesn't detect the iPhone." In 90% of cases, this can be resolved by rebooting the router. Network equipment requires periodic cache resets, especially if there are many devices on the network.
Another common scenario is audio and video desynchronization. This can occur with a weak Wi-Fi signal. Try moving closer to the router or turning off other devices consuming bandwidth (torrents, downloads). Switching your router's frequency from 2.4 GHz to 5 GHz, if your TV supports this range, also helps.
If nothing helps, reset the network settings on your TV. In the menu LG This can be done through Settings → All settings → General → Network → Reset Wi-Fi settingsAfter this, re-enter the wireless network password.
⚠️ Attention: The LG TV menu interface may vary slightly depending on the webOS version and model year. If you can't find a menu item, use the search within Settings (magnifying glass icon) or refer to the online manual for your specific model.
A debug mode is available for advanced users, but it requires caution. Usually, it's enough to check if your router has a speed limit for specific devices (QoS), which could prioritize other devices at the expense of your TV.
