Modern technologies allow you to transform ordinary video viewing into a full-fledged cinema experience using the screen of your LG TV. Broadcast media From a smartphone to a large display has become the standard, but iOS users often face difficulties due to the closed nature of Apple's ecosystem. Owners iPhone may need to display photos, videos or games on the screen LG Smart TV without using wires.
Fortunately, there are proven methods that can help you organize wireless connection between devices. The main tool here is technology AirPlay, which is built into many modern TV models from the Korean brand. If your device doesn't support Apple's native protocol, alternative methods for transferring data over a local network will help.
In this article, we'll cover all the current connection methods, from built-in features to third-party apps. You'll learn how to set up media server, avoid lag during streaming, and achieve maximum image quality. Proper network configuration will ensure stable, lag-free streaming.
Checking compatibility and preparing equipment
Before you begin setting up, you need to make sure that your equipment supports the required protocols. Most models LG Smart TV, released after 2018 and equipped with an operating system webOS versions 4.0 and above have built-in support AirPlay 2This means that owners of such devices do not need to install additional software on their TV.
Both devices – the smartphone and the TV – must be connected to the same network. Wi-FiThis is a critical requirement, as data transfer occurs within the local network. If your router broadcasts two frequencies (2.4 GHz and 5 GHz), make sure both devices can see each other, although modern routers typically combine them into a single network.
It is also worth checking the version of the operating system on your iPhoneFor stable operation, it is recommended to use the latest version. iOSOutdated software may contain errors that prevent the TV from being detected in the list of available devices.
Important! ⚠️ If you have an older LG TV that doesn't have Smart features or runs on an outdated platform, built-in AirPlay won't work. In this case, you'll need to use external set-top boxes or an HDMI cable.
Connect via built-in AirPlay 2
This is the simplest and highest quality method that ensures high-resolution image transmission with minimal latency. Technology AirPlay 2 It allows you not only to duplicate the screen, but also to transmit content from applications directly, using the TV as a decoder.
First, make sure the feature is activated in the TV menu. Access the settings using the remote control by pressing the button. Settings (gear). Find the section General or Connection, then select the item AirPlayMake sure the switch is in the "On" position.
Now take yours iPhoneOpen Control Center (swipe down from the top right corner or swipe up from the bottom, depending on your model). Tap the Screen Mirroring icon (two rectangles). Select your device from the list of available devices. LG TV.
☑️ AirPlay Activation Checklist
When connecting for the first time, a four-digit code may appear on the TV screen. Enter it on the smartphone screen to confirm the pairing. After that, the image from iPhone will appear on the big screen. To stop the broadcast, open Control Center again and tap "Stop Repeat."
Using the LG TV Plus app
If for some reason native AirPlay isn't working or your TV model doesn't support this protocol, you can use the manufacturer's official app. LG TV Plus (formerly known as LG Remote) allows you to control your TV and stream media content.
Download the app LG TV Plus from the App Store to yours iPhoneInstall it and launch it. The app will automatically search for available devices on the network. Select your TV from the list. A connection permission will appear on the TV screen—confirm with the remote.
Within the app, go to the "Media" or "Gallery" section. Here, you can select photos or videos saved on your smartphone's memory and send them to the screen. Please note that this method often only works with local files and may not support streaming from online cinemas.
Why doesn't the app see the TV?
If LG TV Plus isn't detecting your TV, check your router's firewall settings. Sometimes antivirus software or network security settings block detection of DLNA devices. Try temporarily disabling AP Isolation in your router settings.
On new models webOS Some features have been removed in favor of native integrations. Always check the app description in the App Store for your specific model.
Casting via third-party apps (Cast to TV)
When standard tools fail, universal intermediary applications come to the rescue. Programs like Cast to TV, Replica or Web Video Caster allow you to broadcast content that “doesn’t want” to be sent using standard methods.
The principle of such applications is to create a virtual media server. You select a video file or a link to a stream in the application on iPhone, and it transmits data to the TV, which perceives it as a regular DLNA source.
Install the selected application (for example, Cast to TV) to your smartphone. Open it and wait for it to detect your LG Smart TVTap the TV's name to connect. You can now select files from your phone's memory or enter video URLs.
| Application | Content type | Format support | Presence of advertising |
|---|---|---|---|
| Cast to TV | Photos, Videos, Files | MP4, MKV, AVI, JPEG | Yes (in the free version) |
| Replica | Screen mirroring | iPhone full screen | No |
| Web Video Caster | Online video | All browser formats | Eat |
| BubbleUPnP | Local files | Audio, Video, Photo | No |
Important: When using third-party apps to stream online video, make sure the content is not DRM-protected. Services like Netflix or Disney+ often block protected content from being streamed through third-party streaming services for security reasons.
Setting up DLNA and media server
Technology DLNA (Digital Living Network Alliance) is a standard for sharing multimedia on a home network. Televisions LG have a built-in DLNA renderer, which allows them to receive content from any compatible devices, including iPhone.
You don't need to install apps on your TV to implement this method. A controller app on your smartphone is sufficient. The built-in Files app on iPhone may not be able to see network devices directly, so it's better to use third-party file managers with DLNA support, such as VLC for Mobile or OPlayer.
Launch the player app on your iPhone, find the "Network" or "Local Area Network" tab, and select your TV. LG in the list of devices. This will give you access to your TV's folders (if it's connected to a USB drive) or, conversely, you can share a folder from your phone (depending on the app's functionality).
⚠️ Please note: DLNA data transfer speeds are directly dependent on the quality of your Wi-Fi signal. Buffering and stuttering may occur when viewing large 4K files. For a comfortable viewing experience, we recommend using a router that supports this standard. Wi-Fi 5 (AC) or Wi-Fi 6 (AX).
If you use this method frequently, it may be a good idea to set up a static IP address for your TV in your router so that the path to your device doesn't change after a reboot.
Solving common connection problems
Even with proper setup, technical issues may still occur. Most often, the problem lies in network security settings or device caches. If the TV isn't visible in the AirPlay list, try restarting the router—this will refresh the routing tables.
Another common cause is different regions in your Apple ID and TV settings. Make sure that in Settings LG TV (menu General → Country) and in the settings iPhone (General → Language and Region) the correct data has been selected. Sometimes changing the TV's region requires resetting Smart Services.
If you see a picture but no sound, check your audio output settings in Control Center. Also, make sure your TV isn't in "Quiet" mode or that Bluetooth headphones aren't playing, which could be intercepting the audio stream.
⚠️ Note: The menu interface on LG TVs may vary slightly depending on the webOS version. If you don't see the options described, please refer to the user manual for your specific model or update your TV's software.
If you experience frequent connection drops, try disabling the "Smart Connect" feature on your router, which combines the 2.4 GHz and 5 GHz networks. Separate them into different SSIDs and connect both devices exclusively to the 5 GHz network for higher throughput.
Optimizing video and audio quality
To get the best picture, it is important to consider the resolution. If your LG TV supports 4K HDR, and the iPhone is streaming content in 1080p, the TV may not scale the image correctly. In the iPhone settings (Photo and Camera → Formats) you can select "Apple ProRAW Compatible" or "Most Compatible", which sometimes affects the transmitted stream.
The soundtrack also requires attention. If you are using an external speaker system connected to the TV via HDMI ARC or optical output, make sure that the TV sound settings are set to "Pass Through" or "PCM" output format so that the iPhone can transmit multi-channel audio without distortion.
How to improve connection stability?
Place the router as close to the viewing area as possible. Walls and appliances (especially microwaves) interfere with the Wi-Fi signal. If the distance is long, consider using a mesh system or repeater.
Clear the app cache on your TV regularly. Go to Settings → General → Storage and delete temporary files. This will free up processor resources for smoother video stream processing.
Why can't my LG TV see my iPhone via AirPlay?
Most often, the problem is that the devices are on different subnets (for example, "Guest Mode" is enabled on the router) or Bluetooth, which is used for the initial handshake, is disabled on one of the devices. Also, check whether your antivirus software is blocking the Bonjour protocol on the router.
Is it possible to mirror an iPhone's screen to an old LG TV without a Smart TV?
Without a built-in Smart module, this isn't possible directly over Wi-Fi. You'll need to purchase an external set-top box (Apple TV, Chromecast, or Android box) that connects to the TV's HDMI port and handles the signal reception.
The sound is delayed during the broadcast, what should I do?
Audio lag (desync) often occurs when using third-party streaming apps. Try finding the "Audio Delay" feature in the player settings and adjusting the value. If the issue is with AirPlay, try lowering the video quality in the source app or restarting your router.
Is DRM content (Netflix, Kinopoisk) streamed via AirPlay?
Yes, if the app supports AirPlay 2. In this case, the phone acts as a remote control, and the TV decodes the stream itself, ensuring high quality. If the app doesn't support direct ecast, HDCP protection may be triggered, resulting in a black screen, although sound will still play.
