Modern technologies allow you to turn your smartphone into a powerful multimedia control panel, eliminating unnecessary wires and limited screen size. Apple device owners often wonder how to display images from iPhone on the big TV screen LGto enjoy movies in high definition. This is especially important for those who prefer streaming services and online cinemas, as the picture quality on a 4K panel significantly exceeds the capabilities of a mobile display.
Fortunately, the ecosystem Apple and platform webOSThe Wi-Fi network installed on LG TVs works seamlessly with each other. You don't need to be a networking expert to set up a wireless connection. Simply have both devices on the same local network, and you can instantly stream photos, videos, or even mirror your entire screen. In this article, we'll cover all available options in detail, from native features to third-party apps.
Before starting any manipulations, make sure that your router is working stably and the software of both devices is updated to the latest version. Data transfer rate Directly affects image quality: at low Wi-Fi speeds, video may buffer or stutter. We'll look at the nuances that will help avoid lag and audio desynchronization.
Preparing equipment and a Wi-Fi network
The foundation of a successful connection is proper local network configuration. The first and most important rule: iPhone And Smart TV must be connected to the same wireless network. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz signals, make sure both devices can see each other, although modern routers typically combine these bands into a single network.
Check the connection status on your TV. To do this, press the settings button on the remote (usually a gear) and go to the section Settings → Network → Wi-Fi connectionThe status should be "Connected." If the TV is connected via cable Ethernet, and the phone via Wi-Fi, in most cases they will also see each other, but problems with discovery protocols may arise if the router isolates client devices.
Remember that signal strength plays a critical role. If the router is in the next room behind thick walls, the connection speed may drop. In this case, use Wi-Fi repeater or a Mesh system to improve coverage. A weak signal is a common reason why broadcasts drop out mid-sentence.
Using the built-in AirPlay 2 feature
The easiest and highest quality way to broadcast is to use technology AirPlay 2, which is built directly into the webOS operating system of LG TVs released after 2018. This technology allows for high-quality video, audio, and photo streaming with minimal latency. You don't need to install any additional apps on your phone.
To activate the function on your TV, press the button Home on the remote, then find and launch the application Apple AirPlay or go to Settings → Connection → Apple AirPlay and HomeKitMake sure the switch is in the "On" position. You can also set up an access code here: you can require a code each time you connect or allow automatic login for devices that have already been connected to your network.
Now take yours iPhoneOpen Control Center (swipe down from the upper-right corner on models with Face ID or swipe up on models with a home button). Tap the Screen Mirroring icon (two rectangles). Select your device from the list of available devices. LG Smart TVIf this is your first time, a 4-digit code will appear on your TV screen, which you will need to enter on your phone.
☑️ Setting up AirPlay
Once paired, your phone's screen will be fully displayed on your TV. You can even play any movie in your browser. Safari Or in an app that doesn't have built-in Cast support. The image will scale, but keep in mind that the phone's aspect ratio (usually elongated) may leave black bars on the sides on a wide-screen TV.
Streaming via the LG TV Plus app
If built-in AirPlay doesn't work for some reason, or your TV is an older model but still supports Smart TV, the official app will come to the rescue. LG TV PlusThis is a universal tool that turns your smartphone into an advanced remote control and media center. It is available for free download at App Store.
Install the app and launch it. The program will automatically scan the network and find compatible TVs. Select yours. LG TV from the list. A permission request may appear on the TV screen—confirm it with the remote. Unlike screen mirroring, this app allows you to stream specific files (photos, videos, music) stored on your phone directly to your TV.
In the app interface, go to the "Media" or "Gallery" section, select the desired movie or TV series you've downloaded, and press the play button. The advantage of this method is that the phone doesn't consume battery power rendering the image to mirror the entire screen; it simply sends a data stream. However, you can't stream online videos from browsers directly through this app; only local files.
⚠️ Attention: The functionality of the LG TV Plus app may vary depending on the webOS version and the TV's year of manufacture. On newer LG models, the LG ThinQ app, which also handles media management, is more commonly promoted, but the interface may be modified by the manufacturer.
Broadcasting from browsers and video players
Many online cinemas and video services have built-in support for the technology Chromecast or similar protocols that allow you to send a video stream directly to your TV, bypassing the phone's screen. However, in the Apple and LG ecosystem, AirPlay remains the primary bridge. If you're using a browser Safari To watch videos on websites, look for the AirPlay icon directly in the player.
In popular apps such as YouTube, Netflix or IVi, the process is even simpler. Open the video on your iPhone, tap the "Cast" icon (the rectangle with Wi-Fi waves), and select your LG TV. The video will start playing on the big screen, and you can use your phone as a remote control or even lock it—the playback won't be interrupted.
It's important to understand the difference between "Cast" and "Mirror." When casting, the TV downloads video from the internet using its processor and network module. This saves battery life and ensures better quality because the phone doesn't heat up. When mirroring, the phone encodes the video stream and sends it to the TV, which puts strain on the battery and can cause lag on poor Wi-Fi.
Why is there no sound during the broadcast?
If the video is playing but there's no sound, check the audio settings on your iPhone. Sometimes, when connecting external devices, audio defaults to the phone's speaker. Also, try adjusting the volume on the TV using the remote control, rather than using the phone's buttons.
Comparison of connection methods and their features
To help you choose the best method, we've prepared a summary table. It will help you quickly navigate depending on your goals: whether you just want to share photos with friends or watch a heavy 4K movie.
| Method | Image quality | Effect on iPhone charge | Best for |
|---|---|---|---|
| AirPlay 2 | High (up to 4K HDR) | Average | Full screen mirroring, games, presentations |
| LG TV Plus | Medium / High | Low | View photos and local video files |
| Built-in Cast (YouTube, etc.) | Maximum (depending on subscription) | Minimum | Watching movies and TV series online |
| HDMI adapter | Lossless (Native) | Charging is in progress (if there is power) | Stable viewing without network lags |
As can be seen from the table, for watching movies from the Internet wirelessly, the ideal option is to use the built-in functions of applications (Cast) or the native AirPlay 2They provide the best balance between image quality and ease of use. Wired methods remain the preserve of professionals or situations with extremely unstable Wi-Fi.
Solving problems and delays
Even with a perfect setup, technical difficulties can arise. The most common issue is audio and video desynchronization or intermittent image flickering. This almost always indicates bandwidth issues. Wi-FiTry disconnecting other devices that are actively downloading files or rebooting your router.
If your TV doesn't detect your iPhone, check your router's firewall settings. Sometimes the "AP Isolation" feature blocks devices from communicating within the network. Also, make sure your TV has the latest firmware version. Go to Settings → Support → Software Update and click "Check for updates".
⚠️ Attention: The LG TV menu interface may vary slightly depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). The location of network and connection settings may vary. If you can't find the setting you need, use the search tool (magnifying glass) in the settings or refer to the official documentation for your model.
Another consideration is antivirus software. If your router or network has strict security filters, they may block the ports used by the AirPlay protocol. On your home network, it's recommended to lower the security level for local devices to standard to ensure unimpeded media sharing.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Without a Wi-Fi network, AirPlay is impossible to use, as this protocol operates over the local network. The only alternative is a wired Lightning-to-HDMI adapter (or USB-C-to-HDMI for new iPhones), which plugs directly into the TV's HDMI port. Bluetooth is not suitable for live video transmission due to its low speed.
Why is the image not full screen when connected via AirPlay?
This is due to the different aspect ratios. Smartphone screens typically have a 19.5:9 or similar aspect ratio, while TVs have a 16:9 aspect ratio. When mirroring, black bars are inevitable to maintain the aspect ratio. When watching videos through built-in players (YouTube, Netflix), the video will automatically stretch to fill the entire screen, as only the video stream is displayed, not the entire phone interface.
Video lags when watching movies from an iPhone on an LG TV. What should I do?
Most likely, your Wi-Fi channel is not fast enough. Try switching your router to the 5 GHz channel if it's running on 2.4 GHz. Also, close unnecessary apps on your iPhone that may be consuming data (iCloud updates, background downloads). If the issue persists, use the "Cast" method within the video app instead of "Screen Mirroring."
Do all LG TVs support AirPlay?
No, AirPlay 2 support was added to LG models released in 2018 and later running webOS 4.0 and later. Older Smart TV models (2014-2017) will require third-party receiver apps installed on the TV itself or an external set-top box (Apple TV, Chromecast, Android Box).
