Modern technology makes it easy to display images from your smartphone on a large TV screen, which is especially convenient for watching movies, photos, or presentations. Apple device owners often face the question of how to implement screen share (screen mirroring) on LG TVs using only your home Wi-Fi network. Fortunately, most modern LG Smart TV models support the AirPlay 2 protocol, making the process as simple and fast as possible.
However, not everyone knows that successful syncing requires meeting a number of basic requirements regarding software versions and network settings. If your TV was released after 2018, the likelihood of built-in AirPlay support is close to 100%, eliminating the need to purchase additional adapters. In this article, we'll cover all setup steps, potential nuances, and troubleshooting common errors that occur when attempting to connect. iPhone And LG TV.
It's important to understand that a wireless connection requires a stable signal, so your router must be functioning properly. Any interference or channel congestion can lead to image lag or even a complete loss of connection while watching. We'll cover not only the built-in iOS tools but also alternative methods that may be useful if the standard method is unavailable for some reason based on your hardware configuration.
Hardware and software requirements
Before setting up, you need to make sure your hardware meets the minimum technical requirements for screen mirroring. Support for the technology is essential. AirPlay 2 on the TV side or using alternative intermediary apps. This typically applies to LG Smart TV models with webOS 4.0 and above, which were released in 2018 and later.
There are also limitations on the mobile device side: for the Screen Mirroring feature to work natively, you need iPhone No older than the 4th generation, running iOS 11.4 or later. Older models may require third-party apps from the App Store that emulate the data transfer protocol, but are often less stable or contain ads.
⚠️ Attention: Make sure your LG TV has the latest webOS firmware version. Manufacturers regularly release updates that add support for new codecs and security protocols, the absence of which can block the connection.
The key element of the entire system is the wireless router. To transmit high-quality video streams (Full HD or 4K), it is recommended to use a router operating within the range 5 GHz, as it provides sufficient bandwidth to transmit a heavy video signal without compression or artifacts. Older 802.11n (2.4 GHz) routers may not be able to handle the stream, resulting in choppy images.
Preparing your home Wi-Fi network
The most common reason why iPhone The problem with the LG TV is that the devices are connected to different networks or subnets. For the technology to work correctly, DLNA To use AirPlay, both devices must be on the same local network, meaning they must be connected to the same router. If you have a dual-band router, make sure both your phone and TV are connected to either the 2.4 GHz or 5 GHz network.
Some providers and sophisticated routers use a "guest network" feature or AP Isolation, which technically allows internet access but prevents devices within the network from communicating with each other. If you're using a guest Wi-Fi network for your smartphone, the TV simply won't be able to "see" it when searching for available devices to stream.
- 📡 Check the network name (SSID) in the Wi-Fi settings on your iPhone and make sure it is identical to the network name your TV is connected to in the menu
Settings → Network. - 🔒 Disable the "Guest Network" mode on your router if devices are connected through it, as it often blocks local communication.
- 🔄 Reboot your router if the list of available devices is empty - this will help update the ARP and DHCP tables.
It's also worth paying attention to your firewall or antivirus settings if they're installed at the router level. Aggressive security settings can block ports required for the protocol. Bonjour (used to discover Apple devices on the network). On most home networks, the default router settings are sufficient for AirPlay, but corporate or complex home systems may require exceptions.
Setting up AirPlay 2 on an LG TV
On modern LG models, AirPlay is built directly into the webOS operating system, eliminating the need for additional apps. To get started, you need to activate this option in the TV settings menu. Typically, the path to it is as follows: press the settings button on the remote, go to Support or General, and find the item AirPlay.
In the AirPlay control menu, you can configure security settings. By default, the TV can request a code every time you connect, which is a good security measure against unwanted intrusion into your network. You can change the settings so that the code is only requested the first time you connect, or not at all if you're in a trusted home environment.
☑️ Checking AirPlay settings
If your TV doesn't have a built-in AirPlay option, it may be too old (produced before 2018). In this case, you'll need to download the official app. LG TV Plus or third-party alternatives from the LG Content Store, such as "TV Cast" or "AirScreen", which will add the missing functionality programmatically.
What should I do if AirPlay won't turn on?
If the AirPlay switch is grayed out, try completely unplugging the TV for 1-2 minutes (a cold boot). This will clear the system cache and restart the discovery services.
Instructions: How to enable casting from iPhone
Once the TV is set up and the network is verified, you can move on to setting up your smartphone. The screen mirroring process on iOS is standardized and doesn't depend on the phone model, whether it's iPhone 8 or the newest iPhone 15 ProYou need to open the Control Center: on models with Face ID, swipe down from the top right corner of the screen, and on models with a Home button, swipe up from the bottom.
In the menu that opens, find the "Screen Mirroring" icon (two rectangles). After clicking it, the system will begin searching for available devices on the local network. Your LG TV should appear in the list (usually called "[LG] webOS TV" or a custom name if you've changed it). Click it, and if a code appears on the TV screen, enter it on your smartphone.
| Action | iOS interface element | Expected result |
|---|---|---|
| Opening the menu | Swipe from corner (Screen mirroring) | A list of devices appears |
| TV selection | LG TV name in the list | Request code or instant connection |
| Stop | Stop Repeat button | The phone screen will unlock and the TV will return to the TV channel. |
It's important to note that when using active screen mirroring, your smartphone may become hotter and the battery will drain faster than usual. This is normal, as the processor and Wi-Fi module are working in overdrive to encode and transmit the video stream in real time. For longer sessions, it's recommended to keep your phone charged.
Using the LG TV Plus app and third-party solutions
If native AirPlay doesn't work for some reason or your TV model doesn't support it, the official app will come to the rescue. LG TV PlusIt's available for free in the App Store and allows you to not only mirror your screen but also use your smartphone as a remote control and transfer photos and videos from your gallery. However, keep in mind that the quality of streaming through the app may be inferior to native AirPlay.
There are also many third party applications such as Replica or TV CastThey often use technology. DLNA or proprietary protocols for transferring media files. The advantage of such solutions is their versatility—they can even work on older TVs that don't have Smart TV, as long as they're connected to a media player that supports the appropriate software.
- 📲 LG TV Plus: Official solution, better interface, but sometimes requires manual activation of the connection on the TV.
- 🎥 Replica: Specializes in low-latency screen mirroring.
- 📂 VLC for Mobile: Great for transferring video files over the network, supports many formats.
When using third-party software, carefully monitor the permissions you grant to the app. To function properly, the app will require access to your local network and, in some cases, access to your photos. Without local network access permission, iOS will simply block the app from finding the TV on the Wi-Fi network.
⚠️ Attention: Third-party apps may contain ads or offer paid subscriptions for advanced functionality. The official AirPlay method is completely free and has no time limit.
Troubleshooting: TV not detecting iPhone
Failure to find devices is a fairly common problem and can usually be resolved by checking several parameters sequentially. First, ensure that Bluetooth is enabled on both devices. Although data transfer occurs over Wi-Fi, the device discovery protocol (especially in the Apple ecosystem) often uses Bluetooth Low Energy for the initial handshake and identification.
The second common problem is IP address desynchronization. The router may have assigned the TV a new address while the phone still remembers the old one. In this case, a simple reset of network settings or a simple reboot of both devices helps. Turning off the TV and phone, then turning them back on, solves 90% of connection issues.
If the problem persists, check your antivirus software or router settings. Some Child Protection or Parental Control features may block communication between devices, classifying them as unknown or potentially dangerous. Also, try temporarily disabling your smartphone's VPN, as it reroutes traffic and may disconnect your phone from the local network.
Secret reset method
Go to iPhone Settings → General → Transfer or reset iPhone → Reset → Reset network settings. This won't delete your data, but it will reset all Wi-Fi passwords and network configurations.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Without a Wi-Fi network, native screen mirroring is impossible, as AirPlay and DLNA use this protocol. However, you can use a wired connection via a Lightning-to-HDMI adapter (or USB-C-to-HDMI for newer models), connecting the cable directly to the TV's HDMI input. This will ensure maximum quality and zero latency.
Why is there no sound when mirroring the screen?
Most often, the sound automatically switches to the TV, but if it doesn't, check the volume settings on the TV itself. Also, make sure the TV, not the phone speaker, is selected as the audio output device in the iPhone's Control Center. Some apps (such as Netflix) may block sound during screen mirroring due to DRM licensing restrictions.
Does screen mirroring affect internet speed?
Yes, streaming video over a local network puts a strain on your Wi-Fi channel. If you use the same router for both internet sharing and streaming, page loading speeds on other devices may temporarily decrease, especially in the 2.4 GHz band.
Does my old LG TV support AirPlay?
Official AirPlay 2 support is available in 2018 and newer models (B, C, E, W, G, V, P, and R series). Older models (2014-2017) will require connecting an external set-top box, such as an Apple TV, or using third-party emulators if available in the LG Content Store.
