Modern technologies make it easy to integrate Apple mobile devices into your home entertainment ecosystem. If you're wondering how to connect an iPhone to an LG TV via Wi-Fi, you're in luck: it's one of the simplest procedures in the world of smart TV. LG has implemented support for the standard. AirPlay 2 in most of its new models, which makes the broadcasting process as fast and stable as possible.
You won't need extra cables or complicated adapters if your router is working properly. All you need is for both devices to be on the same local network. In this article, we'll cover all synchronization methods in detail, from built-in features to third-party apps, and also explore potential issues and solutions.
Before you begin setting up, make sure that your Smart TV supports Wi-Fi Direct or has a built-in wireless module. Older models may require the use of DLNA servers, but modern ones LG WebOS Work natively with iOS. This allows access not only to photos and videos, but also to mirror the entire smartphone screen in real time.
The main advantage of a wireless connection is the absence of physical restrictions. You can move freely around the room while the movie plays on the big screen. Furthermore, you retain complete control of the content—easily pause, adjust the volume, or skip tracks directly from the screen. iPhone.
Checking compatibility and preparing equipment
The first step to successful syncing is to ensure your equipment is technically ready. Not all LG TV models support Apple protocols equally well. Knowing your TV's operating system version is crucial. If you have a 2019 model or newer, AirPlay 2 support is likely already built-in.
Check the list of supported series to avoid wasting time setting up incompatible devices. Owners of older models (2018 and earlier) can also stream content, but they will need to use the technology Smart Share or third-party apps. The difference lies in connection stability and the range of available features.
⚠️ Please note: LG TV models released before 2018 may not support native AirPlay. In this case, using third-party Android receiver apps (if your TV runs on that OS) or purchasing an Apple TV set-top box will be the only solution for high-quality streaming.
Make sure your smartphone's software is updated to the latest version of iOS. Older versions of the operating system may not support the new encryption protocols used by the TV. Also, check that Wi-Fi is enabled in the TV's settings, as it sometimes turns off when entering power-saving mode.
Stable high-definition video streaming (4K HDR) requires good bandwidth. If the router is far from the TV, the signal may be unstable. Ideally, both devices should be connected within range. 5 GHz, which provides a higher data transfer rate compared to the classic 2.4 GHz.
AirPlay Method 2: Native Apple and LG Integration
The most convenient way to connect an iPhone to an LG TV via Wi-Fi is using AirPlay 2 technology. This protocol allows you to stream videos, photos, and music directly from apps that support this feature. You don't need to install anything additional if your TV is a modern model.
To get started, open the Control Center on your iPhone. Swipe down from the upper-right corner (on models with Face ID) or up from the bottom edge (on models with a home button). Find the "Screen Mirroring" icon (two intersecting rectangles). The system will automatically search for available devices on the network.
- 📺 Select your LG TV from the list of available devices that appears.
- 🔐 Enter the code that appears on the TV screen into the field on the iPhone screen.
- ✅ Confirm the connection, and the image from your phone will instantly be displayed on the TV.
Once paired, you can stream content from YouTube, Netflix, Apple TV+, or any video library. Simply tap the cast icon (the rectangle with waves) in the app player. Picture quality will adapt to your network, but it's typically superior to older wired connections.
⚠️ Note: The first time you connect, your TV may ask for access permission. Be sure to select "Always Allow" or "Allow on First Request"; otherwise, subsequent connections will be blocked by the security system. WebOS.
If you want to stop mirroring, simply open Control Center again and tap "Stop Mirroring." Your phone screen will return to normal mode, and your TV will switch to standby mode or the last signal source. This is ideal for showing presentations or sharing family archives with guests.
Using the LG ThinQ app to control
Official app LG ThinQ (formerly LG TV Plus) is a powerful tool for controlling your TV and streaming media. It functions as a universal remote and media server. This method is especially useful if you want to control playback of files stored directly on your iPhone, rather than on streaming services.
Download the app from the App Store and launch it. The program will automatically scan the network and find your TV. After pairing, which also requires entering a confirmation code, you'll gain access to an extended menu. Here, you can not only stream photos and videos but also use your phone as a touchpad for typing.
☑️ Check before connection
In the app interface, go to the "Media" or "Gallery" section. Select the files you want to display on the big screen. The app supports most popular video and image formats. However, keep in mind that large files of this format HEVC or ProRes may require more resources for decoding on the TV side.
| Function | Description | Requirements |
|---|---|---|
| Photo broadcast | Viewing a slideshow on TV | LG ThinQ or AirPlay |
| Cursor control | Using your phone as a mouse | LG ThinQ |
| Text input | Typing on a smartphone keyboard | LG ThinQ |
| Multimedia | Playing local files | TV codec support |
One of the app's useful features is file transfer. You can transfer a document or photo from your phone directly to the TV's memory (if there's free space) or stream it. This eliminates the need for USB flash drives to display content.
Cast-to-TV via third-party apps
In situations where native methods don't work or the functionality isn't sufficient, third-party solutions come to the rescue. Apps like Cast to TV, Replica or Web Video Caster Allows you to bypass some system limitations. This is especially relevant for older LG models that don't have built-in AirPlay.
These programs operate by creating a local server or using the DLNA/UPnP protocol. You install the app on your iPhone, and you may need to install a receiver on your TV (via the LG Content Store), although often simply launching the built-in Media app on your TV is sufficient.
- 📲 Install the selected casting app on your iPhone from the App Store.
- 📺 Launch the receiver app on your LG TV (if required).
- 🔗 Press the connect button in the app on your phone and select TV.
The advantage of such solutions is their versatility. They can often stream content from browsers that lack a built-in "Cast" button. For example, you can open a video site in Safari, copy the link, and paste it into a casting app, which will send the stream directly to the TV, bypassing the phone's processor.
Why might a third-party application not work?
Often, the problem lies in the router's firewall settings or local traffic blocking by the ISP. Antivirus software on the PC (if a bridge is used) can also block the connection.
It's worth noting that free versions of these apps often contain ads or have session time limits. For regular use, it's worth considering paid versions, which offer a stable, uninterrupted connection and support for higher video bitrates.
Setting up Wi-Fi Direct for a direct connection
Technology Wi-Fi Direct Allows you to connect your iPhone to your LG TV without a router. This creates a direct wireless connection between the two devices. This method is useful in offices or hotels where access to the main Wi-Fi network is password-protected or has data restrictions.
To activate this mode, go to your TV's network settings. Find the "Wi-Fi Direct" section and enable it. The TV will create its own network. On your iPhone, a new network will appear in the Wi-Fi settings with a name that includes your TV model (e.g., LG_webOS_TV_XX). Connect to it by entering the password displayed on the screen.
Once connected, you can use Smart Share features to transfer files. However, keep in mind that in Wi-Fi Direct mode, your phone will lose internet access via Wi-Fi (unless you're using mobile data). This is a limitation of the technology, as smartphones typically only have one Wi-Fi module.
⚠️ Please note: When using Wi-Fi Direct, data transfer speeds may be lower than via a router, especially if the devices are far apart. This method may not be suitable for viewing 4K video due to limited bandwidth.
This method is also convenient for quick screen sharing in environments without network infrastructure. Simply enable Direct on your TV, connect your phone, and start playing content. After you finish sharing, remember to disable the feature on your TV for security.
Solution: Why iPhone Can't Detect My LG TV
Even with proper setup, situations may arise where devices "don't see" each other. The most common cause is that they are connected to different networks. For example, a phone is connected to a guest network. Guest_WiFi, and the TV is in the main Home_NetworkMake sure the network names (SSIDs) are identical.
The second important aspect is client isolation settings on the router. Some providers or network administrators enable the "AP Isolation" feature, which prevents devices within the same network from communicating with each other. On home routers, this option should be disabled in the wireless security section.
Problems can also be caused by outdated software. Check for TV updates in the menu. Settings → Support → Software UpdateManufacturers regularly release patches to fix compatibility issues with new versions of iOS. Sometimes, a simple restart of both devices helps: unplug the TV for 10 seconds and then restart your iPhone.
- 🔄 Restart your router, phone, and TV.
- 📡 Make sure both devices are on the same subnet (e.g. 192.168.1.x).
- 🔒 Disable the VPN on your iPhone if it is activated (it changes your virtual location).
If all else fails, try resetting your TV's network settings. This will delete all saved Wi-Fi passwords, but it often resolves issues with frozen network modules. After resetting, reconnect the TV to the router and try to find it from your iPhone.
Impact of VPN on connection
If a VPN is enabled on your iPhone, the TV may not see the device because search requests (mDNS/Bonjour) go through a secure tunnel and don't reach your local network. Disable the VPN before setup.
