Modern technologies make it possible to transform any Smart TV into a full-fledged multimedia center, and Apple device owners know this firsthand. iPhone and televisions LG with the operating system webOS They work seamlessly with each other, allowing you to stream photos, videos, and even mirror your smartphone's screen to a larger panel without the hassle of wires. However, despite the built-in support AirPlay 2 In newer models, the initial setup process may raise questions for users unfamiliar with the intricacies of network protocols.
For a successful connection, it is critical that both devices are on the same local network. This means that yours smartphoneThe device and TV must be connected to the same router, whether via wired or Wi-Fi. If you're using a guest network or isolated VLANs, standard device discovery methods may not work, as broadcast protocols rely on subnet-wide broadcasts. In this article, we'll cover all current connection methods in detail, from native features to third-party apps.
It is worth noting that the operating system interface webOS may vary slightly depending on the year of your model LGOlder versions (3.0, 4.0) may require additional apps, while newer releases (5.0, 6.0, and later) have built-in support for Apple protocols. Below, we'll cover universal algorithms that cover most use cases and help you set up stable content streaming.
Checking compatibility and preparing the network
Before you begin setting up, you need to make sure your equipment is technically capable of supporting wireless broadcasting. Most TVs LG, released after 2018, have built-in support AirPlay 2, making the process as simple as possible. However, earlier models may require the use of alternative methods, such as DLNA or third-party repeater programs. Checking your model's specifications is the first step to success.
The key factor in connection stability is signal quality. Wi-FiIf your router supports dual-band mode (2.4 GHz and 5 GHz), make sure both devices are connected to the same frequency. Although modern routers can broadcast traffic between bands, some older device discovery algorithms (UPnP) may not work correctly when devices are in different frequency bands. Ideally, use the 5 GHz band for transmitting heavy 4K video content.
β οΈ Important: If your router is configured with Client Isolation or AP Isolation, devices will not see each other on the network. This mode is often enabled on guest networks or corporate Wi-Fi for security, but it blocks AirPlay and SmartShare.
It's also worth checking your TV's software version. Manufacturers regularly release updates that add support for new codecs and protocols. Go to the settings menu and select General and find the item About TVBy clicking the button Software update, you can check for current firmware versions that can fix network stack errors.
Using the built-in AirPlay 2 feature
The easiest and highest quality way to stream content is to use native support. AirPlay 2This protocol, developed by Apple, allows for the transfer of video, audio, and photos, as well as screen mirroring, with minimal latency. This feature requires no additional cables or complex setup; both devices must be on the same network. It's the "gold standard" for the Apple ecosystem.
To activate the feature on your TV, go to Settings webOSYou need to find the section Connection or Connection settings, and then select the item AirPlay and HomeKitMake sure the AirPlay switch is set to OnHere you can also set up an access code: you can require a code every time you connect, only the first time, or disable verification entirely if the TV is on a secure home network.
Now take yours iPhoneOpen the app you want to stream content from (e.g. YouTube, Apple TV+, or your photo gallery). Look for the streaming iconβit looks like a rectangle with a triangle at the bottom or the AirPlay logo. Your device should appear in the list of available devices. LG Smart TVOnce selected, synchronization will begin and the image will appear on the screen.
If you want to mirror your entire smartphone screen (for example, to show the interface of an app that isn't supported), use the Control Center. On models with Face ID, swipe down from the upper-right corner; on models with a Home button, swipe up from the bottom edge. Tap the icon. Screen mirroring (two rectangles) and select your TV.
LG TV Plus and Smart Share app
If native AirPlay doesn't work for some reason or your TV model doesn't support it, the official app will come to the rescue. LG TV PlusThis tool turns your smartphone into a universal remote control and media center. The app is available for download in the App Store and is free. It not only allows you to control your TV but also stream files from your phone's memory to the big screen.
After installing the app, launch it on your iPhone. The app will automatically search for devices on your local network. When your TV appears in the list, tap it to pair it. You may see a connection permission prompt on the TV screen; confirm with the remote. Once paired, you'll have access to control and media streaming features.
To transfer photos or videos, open the section in the application Media or Smart ShareSelect the files you want to play. The app supports most popular video and audio formats, but RAW codecs or specific containers may cause difficulties. In this case, it's best to use the screen mirroring method.
βοΈ Check before connection
It is important to note that the functionality of the application may vary depending on the version. webOSIn some cases, the app functions as a full-fledged remote control, while in others it only functions as a media player. If the connection drops, try restarting the app after completely closing it in the background.
Third-party streaming apps
When built-in tools fail or require advanced functionality (for example, broadcasting Safari browser tabs in a format not supported natively), third-party solutions come to the rescue. The leader in this niche is the app TV Cast for LG TVIt allows you to send web pages, videos, and files directly to your TV, bypassing iOS system limitations.
These apps work similarly: you install the app on your iPhone, open the built-in browser or select a file, and then press the Cast button. The app finds the TV's IP address and sends a data stream. The advantage of these solutions is their versatilityβthey often support older TV models that lack Smart features or AirPlay.
β οΈ Please note: Free versions of third-party apps often contain ads or have video length limits (e.g., 10 minutes). For continued use, you may need to purchase the Pro version.
Another popular option is to use players that support network streaming, such as VLC for MobileThis player has a "DLNA/UPnP Output" feature. You open the video file in VLC, click the cast button, and select your LG TVThe player automatically converts the stream to a format compatible with the TV on the fly, eliminating codec incompatibility issues.
Comparison of connection methods
Choosing the optimal connection method depends on your needs and the equipment model. To help you navigate the process, we've prepared a comparison table of the main methods. It will help you understand which protocol is best for watching movies, playing games, or presenting presentations.
| Method | Image quality | Latency | Difficulty of setup |
|---|---|---|---|
| AirPlay 2 | High (up to 4K HDR) | Low | Minimum |
| LG TV Plus | Medium/High | Average | Low |
| TV Cast (App) | Depends on the format | High | Average |
| HDMI adapter | Maximum | Absent | Low |
As can be seen from the table, AirPlay 2 remains the leader in terms of both quality and convenience. However, if your TV is an older model, DLNA-based methods or third-party apps are excellent alternatives. A wired connection via the Lightning to USB-C HDMI adapter remains the only way to guarantee zero latency, which is critical for gaming but sacrifices the convenience of wireless control.
Troubleshooting connection issues
Despite the simplicity of the technology, users sometimes encounter situations where the TV isn't visible in the list of available devices or the connection keeps dropping. One of the most common causes is IP address desynchronization. The router may have assigned a new address to the device, causing discovery protocols to be lost. In this case, a simple reboot of the network equipment resolves the issue.
Perform a hard reset using the following procedure: turn off your TV (not to standby, but completely unplug it for 10-15 seconds), reboot your router, and restart your iPhone. After turning on all devices, wait 2-3 minutes to allow them to fully load their network modules and register with the network. This often resolves 90% of visibility issues.
If the problem persists, check your antivirus or firewall settings on your router. Some "child protection" or "cybersecurity" features may block local traffic between devices. Also, make sure your TV isn't set to "Wired connection only" in the network settings, if your model has one.
What should I do if the video is lagging?
If the video is choppy or pixelated when streaming via AirPlay, try lowering the output quality in the source app's settings (for example, in YouTube, select 1080p instead of 4K). Also, move closer to the routerβthe Wi-Fi signal can be weakened by walls or interference from a microwave oven.
Adjusting image and sound settings
Once the connection is successful, it's important to properly configure the image output to ensure the content looks its best. TVs LG Aggressive post-processing is often used, which can distort colors when streaming from an iPhone. Go to the picture settings on your TV and select the mode Movie or Technologist (Filmmaker Mode) to disable unnecessary enhancements and see the picture as the creators intended.
Sound deserves special attention. When connecting via AirPlay, audio automatically switches to the TV's audio system or connected soundbar. If you're using Bluetooth headphones connected to your iPhone, the audio may remain in the headphones. To redirect it, open Control Center on your iPhone, tap the AirPlay icon in the media controls, and select the TV as the audio output device.
Multitaskers should know that when streaming video via AirPlay, you can minimize the app on your iPhone and use other smartphone features. However, if you use Screen Mirroring mode, your phone's screen will be completely mirrored, and any notifications or calls will also appear on the larger screen. Be sure to enable Do Not Disturb mode before you start watching.
β οΈ Note: The interface and available features may change after updating your TV's firmware or iOS. If you can't find the menu items described, please refer to the official documentation on the manufacturer's website for your specific model.
Frequently Asked Questions (FAQ)
Why doesn't my iPhone see my LG TV in the AirPlay list?
Most likely, the devices are on different networks (for example, one is connected to guest Wi-Fi and the other to the main Wi-Fi) or client isolation is enabled on the router. Also, check whether your specific LG TV model supports AirPlay 2. Older models will require the LG TV Plus app.
Is it possible to mirror iPhone screen to LG TV without Wi-Fi?
Without a local wireless network (Wi-Fi router), standard AirPlay and SmartShare methods don't work. However, you can use a wired connection via a Lightning-to-HDMI adapter (or USB-C-to-HDMI for newer iPhones) and an HDMI cable. Some models also support Wi-Fi Direct, but its functionality is limited.
Is the sound delayed when watching videos from your phone on TV?
Audio lag often occurs when using third-party apps or when the Wi-Fi signal is unstable. Try restarting your router. If you're using Screen Mirroring, a slight delay (about 1-2 seconds) is normal for wireless technologies and can't be completely eliminated using software.
Does the sound stream to the external soundbar when connecting an iPhone?
Yes, if the soundbar is connected to the TV via HDMI ARC or an optical cable, the iPhone's audio will be transmitted to the TV, which will then route it to the soundbar. Make sure the correct audio output (External Speaker or ARC) is selected in the TV's sound settings.
