Modern technology makes it easy to stream content from your smartphone to a big screen, and for Apple device owners, this is becoming the de facto standard. Connecting an iPhone to an LG TV Wi-Fi provides access to movies, photo galleries, and mobile games in high definition without the need for unnecessary wires. The setup process takes only a few minutes if you know the correct sequence of steps and operating system features. iOS.
The main tool for wireless data transmission is technology AirPlay, which is built into all modern LG Smart TV models. Unlike older methods that required complex router settings or the purchase of additional adapters, today's solution simply requires both devices to be on the same local network. This ensures stable 4K video streaming and minimizes latency when managing content.
In this article, we'll cover in detail how to set up a connection, what apps might be needed for older models, and how to resolve common device detection issues. You'll learn about the protocol's nuances. DLNA and the benefits of native AirPlay 2 support. Proper setup will transform your TV into a fully-fledged multimedia center for the whole family.
Checking compatibility and preparing equipment
Before you start setting up, you need to make sure that your LG Smart TV Supports wireless video streaming. Most models released after 2018 have built-in AirPlay 2 support, making the process as simple as possible. Older models may require additional software installation or the use of third-party intermediary apps.
A critical requirement is that both devices are on the same subnet. This means that iPhone The router and TV must be connected to the same router. If you have a dual-band router, make sure the devices are connected to either the 2.4 GHz or 5 GHz band, as some router security settings can isolate devices from each other even if they are connected to the same access point.
It's also worth checking your software versions. On your TV, you can do this through the settings menu, and on your smartphone, in the iOS update section. Outdated firmware often causes unstable operation or a complete lack of device discovery on the network.
⚠️ Note: If your router is using Guest Network mode or AP Isolation is enabled, devices will not be able to see each other. For proper operation, you must disable these features in your router settings.
To check the compatibility of your model, please refer to the specifications on the official website or try searching for an app LG TV Plus in the App Store. If the app detects the TV upon first launch, the basic network connection is configured correctly. Otherwise, reboot the router and try connecting again.
Connect via built-in AirPlay 2
The highest-quality and most stable streaming method is using Apple's native technology. LG models with AirPlay 2 support allow you to stream images, video, and audio directly through the standard Control Center menu on your iPhone. You won't need to install any additional apps on your TV if it's a modern model.
To activate the feature on your LG TV, go to the settings menu. Find the section General or Connection, then select the item AirPlay and HomeKitMake sure the switch is in the "On" position. You can also set the connection code requirement here, which increases the security of your network.
☑️ Setting up AirPlay
After enabling the feature on your TV, take your iPhone and open 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 of the screen. Tap the Mirroring icon (two rectangles) and select your screen. LG TV from the list of available devices.
If this is your first time connecting, a 4-digit code may appear on your TV screen. Enter it on your smartphone to confirm pairing. The iPhone's image will then appear on the big screen. You can rotate your phone to landscape mode to view the video in full screen.
Using the LG TV Plus app
If automatic detection doesn't work or you need advanced control functionality, the official app LG TV Plus will be a great assistant. It's available for free in the App Store and allows you to not only stream media files but also use your smartphone as a remote control with a touchpad.
After installation, launch the app and follow the on-screen instructions. It will automatically scan the network and display a list of found TVs. Select your model and confirm the connection by accepting the prompt on the TV screen. This is especially convenient if you find the standard remote keypad difficult to use when searching for YouTube or Netflix.
The app features a "Media" or "Gallery" tab, which allows you to select photos or videos stored on your iPhone and send them to your TV. Unlike full screen mirroring, this method allows you to stream only a specific file, freeing up your smartphone for other tasks.
It's worth noting that the app may require certain iOS permissions, such as access to the local network and media files. Without these permissions, functionality will be limited, and you won't be able to share content. Check your privacy settings in the Settings → LG TV Plus on your iPhone.
Streaming via third-party apps and DLNA
For owners of older LG TVs that don't support AirPlay out of the box, there are proven third-party solutions. Apps like Replica, TV Cast or Web Video Caster use the DLNA protocol or their own screen capture algorithms to transfer images.
They work in a similar way: you install the app on your iPhone, and you may need to install a companion app on your TV (via the LG Content Store), although often it's enough to simply launch the built-in browser or media server. For example, TV Cast Allows you to open web pages within its app and cast videos directly to your TV, bypassing the restrictions of some websites.
| Connection method | Image quality | Latency | Requirements |
|---|---|---|---|
| AirPlay 2 (Native) | High (up to 4K HDR) | Minimum | LG 2018+, iOS 11+ |
| LG TV Plus | Medium/High | Low | Installing the application |
| Third Party (TV Cast) | Depends on the codec | Average | Installation on both devices |
| DLNA (Photo/Video) | Original file | Absent | Media server |
When using third-party solutions, it's important to understand that they may consume more battery power. Furthermore, free versions of such apps often contain ads, which may be displayed both on the phone and on the TV screen.
⚠️ Please note: Application and operating system interfaces are updated regularly. Button locations and menu item names may differ from those described in the instructions. Always consult the manufacturer's current manuals if you cannot find the option you need.
Configuring network and security settings
Connection stability directly depends on the quality of the Wi-Fi signal. For high-definition video transmission (especially 4K), it is recommended to use the 5 GHzIt provides high throughput, which is critical for streaming without buffering and compression artifacts.
If your router is broadcasting two networks with the same name (Smart Connect), try temporarily separating them or forcing your TV to connect to the 5 GHz network in its network settings. This can sometimes resolve choppy picture or out-of-sync audio issues.
What to do if the 5 GHz network doesn't work in the living room?
If the 5 GHz signal is too weak due to walls, use a Wi-Fi repeater or mesh system to extend the coverage. Alternatively, you can connect the TV with a LAN cable and leave the iPhone on Wi-Fi—they'll still be on the same network and will be able to see each other.
For security reasons, don't ignore connection confirmation requests. When a new device attempts to connect to your TV, a notification appears on the screen. If you didn't initiate the connection, tap "Decline." This will protect your home network from unauthorized access by neighbors or intruders who may try to display inappropriate content on your screen.
It is also recommended to set a password for the AirPlay function in the TV settings. This can be done in the section Settings → General → AirPlay → Require CodeSelect "First Time" or "Every Time" to have complete control over who can use your display.
Troubleshooting and common errors
Even with proper setup, situations may arise where the iPhone doesn't recognize the LG TV. The first step should always be to reboot both devices. Unplug the TV for 10-15 seconds (to clear the cache), and reboot the iPhone.
Check to see if your router's antivirus or firewall is blocking local device communication. Some ISPs or smart home settings may isolate IoT devices. Temporarily disable your router's complex security features to diagnose the problem.
If the problem persists, try forgetting the Wi-Fi network on your iPhone and reconnecting using the password. Sometimes resetting the network settings on the TV itself (not a full factory reset, but specifically the network settings) can help. Find it in the menu. Settings → Network → Advanced settings → Reset.
In rare cases, an outdated version of the YouTube or Netflix app on your TV can cause a conflict. Update all installed apps through the LG Content Store, as they often contain patches for data transfer protocols.
Why doesn't the TV detect the iPhone, even though there is only one Wi-Fi connection?
Most often, the cause is that the router broadcasts the network on different frequencies (2.4 and 5 GHz) and is configured in isolation mode, or the devices are connected to a guest network. Make sure both devices are connected to the main network and are on the same segment.
Is it possible to connect an iPhone to an LG without Wi-Fi?
A wireless connection is impossible without a Wi-Fi network, as AirPlay and DLNA use the local network to transmit data. However, you can use a wired connection via a Lightning-to-HDMI adapter if your TV has an available HDMI port, but this will no longer be a Wi-Fi connection.
Video is lagging when streaming from iPhone to LG. What should I do?
Delays are usually caused by a weak Wi-Fi signal or channel congestion. Try moving closer to the router, disabling downloads on other devices, or switching the router to a less congested channel in its settings.
