Modern users often need to stream multimedia content from their mobile devices to a large screen. Apple device and LG TV owners are no exception, as the iOS and WebOS ecosystems require proper configuration for smooth operation. Wi-Fi Direct and the AirPlay 2 protocol allow you to establish a connection without using physical cables, ensuring high-quality signal transmission.
The setup process may seem complicated at first glance. In reality, the process is quite simple and takes only a few minutes if you know the exact sequence of steps in the menus of both devices. You'll need a stable network, updated software, and a basic understanding of how wireless interfaces work.
In this guide, we'll cover all available connection methods, possible errors, and troubleshooting methods. We'll pay special attention to the nuances of working with different operating system versions so you can enjoy your content without lag.
Technical Features of Connecting iPhone and LG TV
Before you begin setting up, it's important to understand the differences between data transfer technologies. Many users get confused. Wi-Fi Direct With a standard connection to a router. In the case of LG and iPhone, a hybrid method is most often used, where the TV and smartphone communicate over a local network using the DLNA or AirPlay protocol.
Protocol AirPlay 2 Built into modern LG models, it allows you to stream video, photos, and audio directly. If your TV is an older model, you'll have to rely on an app. LG ThinQ or the Smart Share function, which is also based on the principles of Wi-Fi Direct.
Transmission quality directly depends on channel bandwidth and the absence of interference in the 2.4 GHz or 5 GHz band. For 4K video streaming, the 5 GHz frequency is recommended, as it provides higher data transfer rates.
⚠️ Important: Make sure your router supports 802.11ac or later for stable AirPlay in high definition.
Why is AirPlay better than DLNA?
AirPlay provides lower latency and supports higher-quality audio, and lets you control playback directly from your iPhone's lock screen.
Preparing hardware and software environment
A successful connection is impossible without first preparing both devices. First, you need to check that the software versions are up-to-date. On LG TVs, this is the operating system. webOS, which regularly receives security updates and new features.
The iPhone must also have the latest available version installed. iOSOlder versions of the operating system may not support the required encryption protocols or video codecs. Check for updates in your device settings.
Also, make sure both devices are within a strong signal range. The distance between the router and TV shouldn't be too great, especially if you're using the 5 GHz frequency band, which has poorer signal penetration through walls.
Setting up a wireless network on an LG TV
The first step is to properly configure the TV itself. You need to go to the settings menu and find the section responsible for network connections. This is usually called Settings → Network or All Settings → Network.
Select the "Wi-Fi Connection" connection type and find the name of your home network. Enter the password, making sure to be case-sensitive. Once successfully connected, the TV will receive an IP address and be able to communicate with other devices on the network.
To activate the iPhone signal reception function, you need to enable AirPlay support. Go to the section Apple AirPlay support and toggle the switch to the "On" position. Here you can also set an access code or allow connection without a password.
- 📺 Go to the main menu using the gear button on the remote control.
- 📡 Select the "Network" section and connect to your Wi-Fi router.
- 🍎 Find the "Apple AirPlay" item and activate it.
- 🔒 Set a password to protect against unauthorized connections.
⚠️ Note: The webOS interface may vary depending on the model year. If you don't see the AirPlay option, check for system updates.
Instructions for connecting an iPhone via AirPlay
The easiest and most reliable way to stream content is to use the built-in Screen Mirroring feature. To do this, make sure your iPhone is connected to the same Wi-Fi network as your TV. Open Control Center by swiping down from the top right corner (or from the bottom for models with a button).
Tap the "Screen Mirroring" icon (two rectangles). Select your LG TV from the list of available devices. If a code appears on the TV screen, enter it on your iPhone. The screen from your phone will instantly appear on the big screen.
To watch videos from apps like YouTube or Netflix, you don't need to enable screen mirroring separately. Simply tap the mirroring icon (the rectangle with waves) within the video player and select your LG device.
☑️ Checking the AirPlay connection
Function AirPlay This not only allows you to mirror your screen but also use your TV as external speakers for music. In the Control Center menu, select the audio output section and select your LG TV.
Using the LG ThinQ app to control
If the built-in features don't work correctly or you need advanced functionality, use the official app. LG ThinQIt's available in the App Store and allows you to control your TV, transfer photos and videos, and use your smartphone as a remote control.
After installing the app, launch it and click "Add Device." The program will automatically find the TV on your local network. Follow the on-screen instructions to pair it, confirming the code on the TV screen.
The app includes a "Media" section where you can select photos or videos from your iPhone gallery and send them to your TV. This is a convenient way to share vacation photos with friends on a big screen without having to duplicate the entire phone interface.
| Function | AirPlay | LG ThinQ | Smart Share |
|---|---|---|---|
| Screencasting | Yes | No | Partially |
| Transfer photos/videos | Yes | Yes | Yes |
| Remote control | No | Yes | No |
| Stability | High | Average | Low |
Alternative methods: DLNA and third-party apps
In situations where standard methods do not work, you can use the protocol DLNAMany iPhone video players, such as VLC or Infuse, have built-in DLNA support. They can find your TV on the network and stream video files to it.
To do this, open the video file in the player, select the "Cast" or "Renderer" option, and find your LG TV. This method is great because it doesn't require screen mirroring, meaning your iPhone's battery drains more quickly, allowing you to use other apps.
There are also paid mirroring apps that use their own drivers for connection. These can be useful for very old TV models that don't support AirPlay, but they often suffer from image lag.
Solution and troubleshooting
Users often encounter a problem with their TV not being visible in the device list. First, check if the "AP Isolation" feature is enabled on your router. If it's enabled, devices on the Wi-Fi network can't "see" each other.
Another common issue is audio and video desync. This can be resolved by rebooting the router and disabling energy-saving modes on the TV. Also, make sure unnecessary background apps are disabled on the TV.
If the connection keeps dropping, try forgetting the network on your iPhone and reconnecting. Sometimes resetting the network settings on the TV itself via the menu helps. Settings → General → Factory Reset (be careful, this will delete your data).
⚠️ Please note: Antivirus software and firewalls on your computer or router may block ports required for AirPlay and DLNA to work.
Why isn't my LG TV showing up in the AirPlay list?
The most common issue is that the devices are on different subnets (for example, one on 2.4 GHz, the other on 5 GHz, and the router is isolating them) or the guest network is enabled. Make sure both devices are connected to the primary SSID.
How to improve picture quality during broadcasting?
Close all background apps on your iPhone to free up CPU resources. Move closer to the router. If possible, connect the TV to the router via a LAN cable; this will stabilize the signal from your iPhone.
Is it possible to connect an iPhone to an LG without Wi-Fi?
Without a wireless network, you can only use a wired connection via the Lightning/USB-C to HDMI adapter. Pure Wi-Fi Direct (without a router) is not supported for iPhone and LG devices for video streaming; an access point is required.
