Owners of modern Apple smartphones often want to view their favorite movies or photos on the big screen, but don't know how to connect their iPhone to an LG TV via Wi-Fi. This is a completely solvable problem, allowing access to multimedia content without the hassle of wires. Modern technologies make it possible to stream high-definition images using your home wireless network.
The setup process depends on the year of manufacture of your Smart TV and iOS operating system versions. Older models may require third-party apps, while newer TVs support the native AirPlay 2 protocol. Understanding how wireless data transfer works will help you avoid errors when synchronizing devices.
In this article, we'll cover all possible connection methods in detail, from built-in features to specialized software. You'll learn how to set up DLNA server, use technology Miracast (if supported by emulators) or activate AirPlayProper router and TV configuration is the key to a stable, lag-free picture.
Checking compatibility and preparing equipment
Before you begin setup, you need to make sure your equipment supports the required protocols. Most LG TVs released after 2018 and running on the platform webOS, have built-in AirPlay 2 support. This significantly simplifies the task, as it does not require installing additional software on the TV itself.
If you have an older model, you will have to rely on technology DLNA or third-party receiver apps. In any case, both devices—the iPhone and the TV—must be on the same local network. This is critical, as data transfer occurs directly between the devices via the router.
Make sure your Wi-Fi router is broadcasting at 5 GHz, if possible. This will ensure higher throughput, which is especially important for watching 4K or HDR movies. The 2.4 GHz frequency can cause image stuttering and audio out of sync.
- 📺 Make sure Smart TV is enabled on your LG TV and you are signed in to your LG Service account.
- 📶 Make sure your iPhone is connected to the same Wi-Fi network as your TV (important if you have a dual-band router).
- 🔄 Update your TV firmware to the latest version via the menu
Settings → All settings → Support → Software update. - 📱 Make sure your iPhone is running the latest version of iOS for maximum compatibility.
⚠️ Note: If your router has a "Guest Network" feature or AP client isolation, devices may not be able to see each other. Make sure these features are disabled for the main network.
It's also worth checking the status of LG Service. Sometimes, re-authorization is required for built-in apps to function properly. Go to your TV settings and check for system updates and pre-installed apps. This will eliminate any software conflicts when attempting to connect.
Using built-in AirPlay 2 support
The easiest and highest-quality way to stream content is to use native AirPlay 2 support. This technology is built directly into the iOS operating system and webOS interface. You don't need to download or install anything if your TV is a supported model (OLED, NanoCell, and UHD series 2018 and newer).
To get started, you need to enable signal reception on your TV. Go to the settings menu, find the section for mobile device connections, and make sure the AirPlay slider is set to "On." After this, your TV will be visible to iPhones within range.
On your iPhone, open Control Center (swipe down from the upper-right corner or up from the bottom, depending on your model). Tap the "Screen Mirroring" button (the icon with two rectangles). Select your LG TV from the list of available devices.
☑️ AirPlay Test
When you first connect, a confirmation code may appear on your TV screen. Enter it on your iPhone. Once the devices are successfully paired, they will reconnect automatically whenever you're in range. This ensures instant streaming.
- 🔒 Set up a passcode in the AirPlay menu on your TV to prevent neighbors from connecting to your screen.
- 📶 Use a stable Wi-Fi connection, as AirPlay is sensitive to data packet loss.
- 🎞️ For videos from apps (YouTube, Netflix), use the "Cast" button inside the player, not screen mirroring.
It's important to note that when screen mirroring, the iPhone's entire image is transmitted, including notifications and the interface. If you're watching a video from an online cinema, it's better to use the built-in Cast button to use the TV's decoder rather than your phone's. This will save battery life and reduce the load on your smartphone's processor.
Setting up the LG TV Plus and Smart Share app
If for some reason AirPlay doesn't work or your TV model doesn't support this protocol, the official app will come to the rescue. LG TV Plus (formerly known as the LG Remote). It not only controls your TV but also streams photos and videos from your iPhone's gallery.
Download the app from the App Store and launch it. The program will automatically scan the network and find your TV. After pairing (confirming the code on the TV screen), go to the Media section. Here you can select the files you want to display on the big screen.
Technology Smart Share (DLNA) allows you to stream files directly, bypassing complex streaming protocols. This is especially useful for viewing locally stored video files that aren't supported by online services. Streaming quality depends on the file format and the TV's codec capabilities.
Why might the video be lagging?
DLNA streaming lags are often caused by high video bitrates or a weak Wi-Fi signal. Try lowering the quality or moving closer to the router.
For users who frequently watch content on their phone, this app becomes a convenient remote control. It allows you to use your smartphone's keyboard to enter text in the TV's search bar, which is significantly faster than navigating with the Magic Remote. This improves the overall ease of use of your Smart TV.
- 📂 The application supports most popular video and audio formats, but not all codecs.
- 🔋 Running the app in the background can consume your iPhone's battery.
- 🎮 The app offers additional features, such as a game controller for simple games.
It's worth noting that the LG TV Plus app isn't a full-fledged media server. It's more of a remote control with file transfer capabilities. For more complex media library management needs, it's best to consider other software options.
Broadcasting via third-party receiver applications
Owners of older LG models that don't support AirPlay can turn their TV into a fully-fledged iPhone receiver. This can be done using emulator apps installed directly on the TV via the LG Content Store.
One of the popular solutions is the application TV Cast or similar third-party developers. They work simply: you install the app on your TV, open it, and it creates a virtual receiver. On your iPhone, you open a browser or a dedicated companion app and select this receiver.
This method is often used to stream video from browsers that don't have a built-in Cast button. For example, if you're watching a video on a website that doesn't support Chromecast or AirPlay, this intermediary app will allow you to mirror the video to your screen. However, the quality and stability may be inferior to native methods.
⚠️ Please note: The LG Content Store interface may vary depending on your region and TV year. Some apps may not be available in your country.
When using third-party solutions, it's important to monitor ads. Free versions of such apps often contain embedded ads that can interrupt your viewing experience. Paid versions typically eliminate these limitations and offer more stable codec performance.
- 📺 Search for highly rated apps in LG Content Store for better compatibility.
- 🚫 Ad blockers may interrupt streaming in free versions of the software.
- 🔄 Some apps require installing a companion app on your iPhone.
There are also universal media servers, such as Plex. By installing the Plex server on your computer and the client app on your LG TV, you can stream content from your iPhone to your computer and then to your TV. This is a more complex but powerful setup for setting up a home theater.
Comparison of connection methods
To choose the best way to connect your iPhone to an LG TV via Wi-Fi, it's worth comparing the available options based on key parameters. Each method has its own advantages and disadvantages, depending on your goals: simply displaying photos or watching a 4K movie.
Native AirPlay 2 leads the way in terms of convenience and quality, but it's only available on new devices. DLNA and third-party apps offer a lifeline for older devices, but they require more user interaction and can be less stable.
| Method | Required software | Quality | Complexity |
|---|---|---|---|
| AirPlay 2 | Built into iOS/webOS | High (up to 4K HDR) | Low |
| LG TV Plus | iPhone app | Medium/High | Low |
| DLNA (Smart Share) | Built-in | Depends on the format | Average |
| Third-party receivers | Application on TV and iPhone | Average | High |
As the table shows, AirPlay is the ideal choice for most users with modern technology. However, if your TV is a few years old, don't despair—DLNA and third-party app functionality is sufficient for comfortable content viewing.
The choice of method also depends on the type of content. For interactive tasks, such as presentations or app interface demonstrations, full screen mirroring is best. For passive movie viewing, video streaming protocols (Casting) are preferable to reduce the smartphone's load.
Network Solution and Optimization
Even with proper setup, connection issues may still occur. These are most often related to an unstable wireless network or software glitches. If your TV doesn't detect your iPhone, the first step is to reboot both devices and the router. This is a classic but effective step.
Check your router's firewall settings. Sometimes antivirus protection or strict security settings block local device discovery (mDNS). Try temporarily disabling traffic filtering to check.
If the image is choppy or the audio lags behind the video, the problem is almost always bandwidth. Make sure other devices on the network aren't hogging the bandwidth (for example, torrents or game downloads). A connection speed of at least 25 Mbps is recommended for viewing 4K content.
In some cases, resetting the network settings on your TV can help. Go to Settings → Network → Wi-Fi Connection → Advanced Wi-Fi Settings and select "Edit" for your network, then "Delete." Then reconnect, entering the password. This refreshes the network configurations and often resolves visibility issues.
- 📡 Place the router closer to the TV or use a Wi-Fi repeater to strengthen the signal.
- 🔌 Disconnect other devices from Wi-Fi while viewing heavy content.
- 🛠️ Reset your TV's network settings if your device has disappeared from the list of available devices.
⚠️ Note: Wireless modules in TVs may not perform as well as modern smartphones. If the signal is weak, consider connecting the TV to the router via a LAN cable and leaving your iPhone on Wi-Fi.
