It's much more enjoyable to enjoy your favorite movie or photo on a larger display. LG Smart TV, taking advantage of wireless connectivity. Connecting via Wi-Fi Allows you to instantly stream images without unnecessary wires, preserving the aesthetics of your interior and freedom of movement around the room.
The process of synchronizing devices from Apple and the South Korean brand LG has become much easier with the introduction of the protocol AirPlay 2Now you don't need to search for complicated adapters or HDMI cables if both devices are on the same network. In this article, we'll cover all current connection methods, from native system functions to specialized software.
Data transfer quality directly depends on the stability of your router and the firmware version of your TV. Before starting setup, make sure your LG WebOS Updated to the latest version, as support for many modern standards is added through software updates. We'll cover the nuances of working with different TV generations and help resolve common connection issues.
⚠️ Note: The menu interface on LG TVs may vary slightly depending on the version of the webOS operating system (3.0, 4.0, 5.0, 6.0, 22, 23, and later). If you can't find a menu item, try using the search bar in the settings or consult the user manual for your specific model.
Equipment preparation and basic requirements
The foundation of successful wireless broadcasting is a properly organized local network. First, make sure that yours iPhone, and TV LG connected to the same network Wi-FiA common mistake users make is having one device on the 2.4 GHz band and another on the 5 GHz band, while client isolation or guest mode is enabled on the router, which prevents them from discovering each other.
It's important to understand that transmitting high-resolution video (4K or HDR) requires a stable signal. If the router is located in another room behind thick walls, lag or audio desync may occur. Ideally, the distance between the signal source and receivers should not exceed the standard signal range, typically around 10 meters indoors.
Please make sure the software on both devices is up to date. iPhone go to Settings → General → Software Update and install available updates. On your LG TV, press the settings button on the remote, select All Settings → Support → Software Update. Native AirPlay 2 support was added to LG TVs released in 2018 and later, as well as some 2019 models. If you have an older model, using Apple's built-in protocol will not be possible, and you will have to resort to third-party solutions.
Using the built-in AirPlay 2 feature
The highest quality and most stable way of broadcasting is to use technology AirPlay, which is built directly into the iOS operating system. This protocol allows for the transmission of not only images but also high-quality audio, as well as playback control directly from the smartphone's lock screen. For this feature to work, the TV must support this standard, as discussed in the previous section.
Activation of this feature on the TV is usually automatic, but sometimes requires manual activation in the menu. Go to the TV settings and find the section Connection or General, and make sure that the item AirPlay Switch to the "On" position. Some models require connection confirmation via a code that will appear on the TV screen during the first pairing attempt.
☑️ Check AirPlay readiness
To start the broadcast, open iPhone "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. Find the "Screen Mirroring" icon (two intersecting rectangles) and tap it. Select your device from the list of available devices. LG TV.
If this is your first time connecting, a four-digit code may appear on your TV screen. Enter it on your smartphone to confirm trust between the devices. After that, the image will appear iPhone The entire broadcast will be copied to the big screen. To stop the broadcast, open Control Center again and tap "Stop Repeat."
Streaming content through aggregator apps
Many popular streaming services and video hosting sites have a built-in Cast function that works independently of the system's AirPlay. Apps like YouTube, Netflix, Vimeo or ivi use the protocol DIAL or custom algorithms for searching devices on the network. This is often a more convenient method, as it allows you to use your phone for other tasks while browsing.
Launch the app on your smartphone and find the streaming icon (usually a rectangle with waves in the corner). Tap it and select your TV from the list. Unlike full screen mirroring, here your phone acts as a remote control, sending the TV only a link to the video stream, which the TV downloads automatically.
The advantage of this method is that it reduces the load on your wireless network and eliminates the lag typical of mirroring. However, image quality will be limited by the app's capabilities and internet speed, not your local network. Make sure your phone and TV app accounts are synced if you want to resume watching from the same spot.
Using third-party apps for older models
Owners of LG TVs released before 2018 don't have built-in AirPlay support, but that doesn't mean wireless streaming is unavailable. The market offers a variety of intermediary apps that can be installed on the TV through a store. LG Content Store and on the smartphone from App StorePopular solutions include TV Assist, AirScreen or Web Video Caster.
These apps work simply: they create a virtual receiver on your TV that emulates the AirPlay or DLNA protocol, which is supported by iPhone. After installing the app on your TV, launch it and follow the on-screen instructions. Typically, you'll need to scan a QR code or enter the IP address into the app on your smartphone.
| Application name | Connection type | Advertising support | Broadcast quality |
|---|---|---|---|
| TV Assist (LG) | Proprietary protocol | No | High (Full HD) |
| AirScreen | AirPlay / Chromecast | Available in the free version | Depends on the network |
| Web Video Caster | DLNA / Cast | No | Up to 4K (local) |
| Replica | WebRTC | There is a paid version | Average (there are lags) |
It's worth noting that using third-party software can introduce a slight delay (lag) between actions on the phone and what appears on the screen. This is critical for games, but is practically unnoticeable when watching movies. Some apps may require purchasing a premium version to remove watermarks or increase the video stream bitrate.
Broadcast photos and videos from the gallery
If you want to show your friends photos from your last vacation or a video you took with your camera, it's best to use the system's built-in features without installing any extra software. Open the Photos app on iPhone, select the desired media file and click the "Share" button (square with an arrow pointing up). In the action menu, find the icon AirPlay.
This method allows you to display individual photos or entire albums in slideshow mode on your TV. The TV will display the content in its native resolution, adapting to the screen matrix. If you're streaming video from your gallery, make sure the file format is compatible with your TV's codecs, although AirPlay often handles on-the-fly conversion on your smartphone.
What should I do if the video doesn't play?
If you see a black screen with sound when trying to stream a video, the file format isn't directly supported by your TV. Try using a third-party iPhone player with built-in streaming functionality or converting the file to MP4 (H.264) format.
For group viewing, create a separate "For TV" album and stream it in its entirety. This will eliminate the need to constantly switch tracks or manually scroll through photos. Remember that while streaming, your smartphone screen can remain active, allowing you to sort or edit photos without interrupting the big screen.
Solving common connection problems
Even with proper configuration, situations may arise where devices "don't see" each other. First, check your router's firewall settings. AP Isolation (Access Point Isolation) prevents devices within a Wi-Fi network from communicating with each other, allowing only internet access. This feature must be disabled in the router settings.
Another common issue is a full network settings cache. Try a full reset: unplug the TV and router for 30 seconds, then plug in the router, wait for the network to load, and only then turn on the TV. On an iPhone, toggling Airplane Mode may help.
⚠️ Caution: If you're using a dual-band router with the same network names (SSIDs) for 2.4 GHz and 5 GHz, try temporarily separating them or forcing one device to switch to the other frequency. Some older implementations of discovery protocols don't work well in mixed environments.
If the problem persists, reset the network settings on your TV. In the menu All Settings → Connection → Wi-Fi Select "Delete" or "Forget Network," and then reconnect by entering the password. On iPhone, you can use the Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings, which won't delete your data, but will clear saved Wi-Fi passwords.

Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Yes, this is possible with a wired connection. You'll need a Lightning-to-HDMI adapter (or USB-C-to-HDMI for newer iPhone models) and a regular HDMI cable. This will ensure the best picture quality without lag, but will limit your portability.
Why is there no sound when streaming via AirPlay?
Check your sound settings in Control Center. Make sure your LG TV is selected as the audio output device, not your phone's speaker or Bluetooth headset. Also, make sure the volume on your TV isn't turned down.
Do older LG TVs (2016) support AirPlay?
Officially, native AirPlay 2 support began with 2018 models. For TVs from 2016 and earlier, you need to use third-party apps from the LG Content Store or connect an external set-top box (Apple TV, Chromecast).
How to reduce image lag when playing iPhone games on TV?
When gaming, screen sharing over Wi-Fi almost always introduces lag. To minimize lag, use a wired HDMI connection. If Wi-Fi is the only option, ensure both devices are running on the 5 GHz band and close background apps on your phone.
