Modern technology allows you to completely eliminate unnecessary wires, turning your living room into a true multimedia center. Connecting your smartphone to a big screen is the easiest way to share photos with friends, watch a movie from an online cinema, or even play mobile games on your TV. Owners of Apple devices and Korean LG TVs often wonder how to integrate these devices into a single ecosystem without HDMI cables.
Fortunately, the system webOS, which is preinstalled on most modern LG TVs, has excellent compatibility with iOS. This means you don't need to buy complicated adapters or third-party set-top boxes. Simply ensure both devices are on the same wireless network, and you can stream content in high quality. In this article, we'll cover all available connection methods, from native AirPlay 2 before using proprietary applications.
Before you begin setup, make sure your router is stable, as video streaming requires sufficient bandwidth. If the network is overloaded with other devices, you may experience lag or image artifacts. For smooth 4K video streaming, it is recommended that both your TV and iPhone operate in the 5GHz band.
Hardware and software version requirements
Connection success directly depends on the age of your devices and the software versions installed. Not all LG TV models support the AirPlay protocol, which is the primary protocol for connecting to iPhones. Typically, these are models released after 2018 and running webOS 4.0 or higher. For a complete list of compatible models, it's best to check the official user manual for your specific model.
Regarding your smartphone, the requirements are more flexible. Screen Mirroring and AirPlay require iOS 12.3 or later. If you have an older version of the operating system, the standard methods may not work, and you'll have to find workarounds using third-party apps. You can check your version in your phone's settings under "General."
⚠️ Note: The menu interface on LG TVs may vary slightly depending on the webOS version and regional firmware. If you don't find an exact match, look for similar sections in the general settings.
It's also worth paying attention to your router settings. In some cases, if AP Isolation is enabled, devices connected via Wi-Fi cannot see each other, even if they're on the same network. This feature is often used in public spaces, but at home, it can interfere with the proper operation of smart devices.
Setting up AirPlay 2 on an LG TV
The first and most preferred method is to use built-in AirPlay 2 support. This protocol was developed by Apple specifically for wireless content transmission, ensuring minimal latency and high picture quality. On LG TVs, this feature is built right into the system, so no additional software installation is required.
To activate the function, you need to go to the TV settings menu. Using the remote control Magic Remote, press the settings button (gear icon) and go to the "General" section. Here you should find the "AirPlay Settings" option. If you don't see this option, your model may not support this technology, and you should consider alternative connection options.
In the AirPlay menu, make sure the switch is in the "On" position. You can also configure security settings here, such as requiring a code on first connection or restricting access to devices on the same network. This is an important safeguard against unwanted intrusion into your home network.
☑️ Check AirPlay readiness
Once enabled, an AirPlay icon may appear on your TV screen, confirming it's ready. Your device is now visible to all iPhones and iPads within range. If the icon doesn't appear immediately, try restarting your TV by turning it off and then on again using the power button.
Connecting an iPhone via the standard iOS menu
Once the TV is set up, you can move on to setting up your smartphone. Screen mirroring in iOS is very convenient and doesn't require installing any additional apps. Simply open the Control Center and select the desired device from the list of available devices.
On an iPhone with Face ID, swipe down from the top-right corner of the screen to open Control Center. On models with a Home button, swipe up from the bottom. Find the "Screen Mirroring" icon, which looks like two rectangles. Tap it, and the system will search for compatible devices on the network.
In the list that appears, you should see the name of your LG TV. Tap it. If this is your first connection, a four-digit code may appear on the TV screen. Enter this code on your iPhone to confirm the pairing. Your phone's image will then instantly appear on the big screen.
It's important to understand the difference between simply streaming video from an app (like YouTube) and full screen mirroring. With mirroring, everything that's happening on your smartphone, including notifications and your home screen, is displayed on your TV. This can be inconvenient if you receive a private message while watching a movie.
⚠️ Please note: When mirroring your iPhone, your battery drains significantly faster than usual due to increased strain on the processor and Wi-Fi module. It is recommended to keep your phone charged during extended sessions.
Using the LG TV Plus app
If the built-in methods don't work for some reason or the AirPlay functionality isn't enough for you, you can use the official app LG TV PlusThis is a powerful tool that turns your iPhone into an advanced remote control and media center. The app is available for free download in the App Store.
After installation, launch the app and follow the on-screen instructions. It will automatically scan the network and find your TV. You'll need to confirm the connection by verifying the code on your phone and TV screens. The app not only allows you to stream photos and videos from your gallery but also control content playback.
One of the key features of LG TV Plus is the ability to transfer files in certain formats that may not be supported by native iOS tools when connected directly. The app also allows you to display text documents and presentations, which can be useful for office work or study.
The app's interface is intuitive, but it's worth noting that it requires local network access permission. Without this permission, the app won't be able to "see" the TV. Check these settings in the "Privacy" section of your iPhone's settings if the connection fails.
What should I do if the app doesn't detect the TV?
Make sure both devices are connected to the main network, not the guest network. Some routers isolate the guest network, preventing data exchange between devices. Also, try temporarily disabling the VPN on your phone if it's enabled.
Broadcasting via third-party applications (Web Video Caster and similar)
In situations where standard protocols fail or you need to stream content from a browser, third-party solutions come to the rescue. Applications like Web Video Caster or Replica often become a salvation for owners of older TV models or specific content.
They work by taking a video stream from a browser or local file and redirecting it to the TV using their own transmission protocol. This allows them to bypass some iOS restrictions related to video format or DRM protection.
The user interface of such programs usually offers a choice of output devices after the video starts. You select your LG TV from the list, and playback begins on the big screen while your phone can be used for other tasks. This is convenient because it doesn't lock your smartphone's screen.
However, it's worth remembering that free versions of such apps often contain ads, and streaming quality may depend on the developer's servers. Regular use may require purchasing a premium version, which incurs additional costs.
Comparison of connection methods and their features
Choosing the optimal connection method depends on your specific needs and equipment model. Each method has its own advantages and disadvantages that should be considered. Below is a table to help you understand the differences.
| Method | Image quality | Latency | Battery consumption |
|---|---|---|---|
| AirPlay 2 | High (up to 4K HDR) | Low | Average |
| LG TV Plus | Medium/High | Average | High |
| Third-party applications | Depends on the codec | High | High |
| HDMI adapter | Maximum | Absent | Minimum |
As the table shows, AirPlay 2 is the most balanced option for most users. It provides excellent quality and acceptable latency, which is important even for watching videos, not to mention gaming. A wired connection via an adapter remains the only way to achieve absolutely zero latency.
Using third-party apps is only advisable if there are file format compatibility issues. If your TV is older and doesn't support AirPlay but has Smart TV features, these apps may be the only wireless bridge between your phone and the screen.
Solving common connection problems
Even if you follow all the instructions, technical glitches sometimes occur. Most often, the problem is simply a matter of network desynchronization. Make sure your phone hasn't switched to 4G/5G mobile data while the TV is still on Wi-Fi. They must be on the same subnet.
Another common cause is an overflowing router cache or a temporary malfunction in the network modules. A simple router reboot (unplug it for 10 seconds) often resolves the issue when devices stop communicating with each other. It's also worth checking if your router has a limit on the number of connected devices.
If you see a picture but no sound, check your iPhone's audio output settings. Sometimes the system will automatically continue to output sound to the phone's speaker even while the picture is being played. In the Control Center, under the playback section, tap the AirPlay icon and make sure the TV is selected.
⚠️ Note: If you are using a dual-band router with the same network names for 2.4GHz and 5GHz, try temporarily separating them or force both devices to connect to the 5GHz band for stability.
In rare cases, resetting your iPhone's network settings can help. This will delete saved Wi-Fi passwords, so be prepared to re-enter them. After the reset, your phone will re-request all necessary permissions the first time you connect to your TV, which may resolve the software conflict.
Frequently Asked Questions (FAQ)
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 quality and the least amount of lag, but it will require an available port on your TV.
Why isn't my LG TV showing up in the AirPlay list on my iPhone?
The most likely cause is that the devices are connected to different Wi-Fi networks (for example, one to the main Wi-Fi network and the other to a guest network). Also, check that AirPlay is enabled in the TV's settings and that the router's firewall isn't blocking the local connection.
Video is lagging when streaming from iPhone to LG. What should I do?
Lag is often caused by a weak Wi-Fi signal or channel congestion. Try moving closer to the router, turning off downloads on other devices, or switching to a 5 GHz network. Closing background apps on your smartphone can also reduce the load.
Do older LG TVs support AirPlay?
Native AirPlay 2 support was introduced in 2018 and newer models. Older Smart TV models may not have this feature out of the box, but it can sometimes be added using external set-top boxes (Apple TV, Chromecast) or third-party server apps on a PC.
Is it possible to output sound only to the TV and leave the picture on the phone?
In standard AirPlay mode, this works the other way around: the picture and sound go to the TV, and the phone acts as the remote. However, some apps (YouTube, Netflix) have a dedicated "Cast" button that sends the video stream to the TV, allowing you to use your phone for other tasks while the video plays on the big screen.
