A modern home theater is easy to assemble using devices you already have on hand. Apple smartphone owners often wonder how to output a high-quality image from a small screen to a larger display to enjoy their favorite movies in high definition. iPhone to the TV LG via a wireless Wi-Fi network is the most elegant and convenient solution, eliminating the need for unnecessary wires and adapters.
The main task here is to establish a stable data transmission channel that will transmit the video stream without delays and artifacts. The technology allows for the use of built-in operating system functions. iOS, as well as specialized apps from the TV manufacturer. It's important to understand that connection quality directly depends on the speed of your router and the spatial location of your devices.
In this article, we will examine in detail all available synchronization methods, starting from native support AirPlay 2 and ending with third-party streaming utilities. You'll learn how to set up your network, which apps to install, and how to avoid common mistakes that can interfere with your content enjoyment. Follow the instructions to turn your TV into a smart entertainment center.
Preparing your home network and equipment
The first and most critical step is ensuring the local network is functioning properly. For smooth streaming of high-definition video (Full HD or 4K), both devices—the smartphone and TV—must be on the same subnet. This means they must be connected to the same router. If you have a dual-band router, make sure both devices can see each other, even if one operates on 2.4 GHz and the other on 5 GHz, although a dual-band router is preferable for video streaming. 5 GHz.
Check the software version on your TV LGManufacturers regularly release updates that improve the stability of the Wi-Fi module and add support for new data transfer protocols. Go to the Settings menu, select "General," and find "Software Update." If a new version is available, be sure to install it before beginning setup.
⚠️ Important: If your router has a "Guest Network" feature, do not connect streaming devices to it. Guest networks often block data exchange between connected clients, so the TV simply won't see the phone.
It's also worth considering the distance between the router and the signal receiver. Walls, especially load-bearing ones, and household appliances can cause interference. For a perfect picture, try to position the router so the signal reaches the TV viewing area without significant loss of power. Connection stability is more important than absolute range.
AirPlay 2: Native Apple Support on LG TVs
Starting with the 2018 models, the company LG implemented direct support for the technology AirPlay 2This is the simplest and most reliable method, requiring no additional apps on the TV. The protocol allows not only for video streaming but also for transmitting audio to external audio systems and sharing the smartphone screen in real time.
To activate this feature, you need to ensure it's enabled in your TV's settings. It's usually enabled by default, but in some cases it may be disabled for security or privacy reasons. Checking this setting only takes a few seconds and can eliminate many connection issues in the future.
☑️ Checking AirPlay settings
To start broadcasting, open the Control Center on your iPhoneOn models with Face ID, swipe down from the upper-right corner; on models with a Home button, swipe up from the bottom. Tap the "Screen Mirroring" icon (two rectangles). Select your TV from the list of available devices. LGIf this is the first time you've tried it, a code may appear on your TV screen that you'll need to enter on your smartphone.
Once paired successfully, your phone's screen will be fully mirrored on your TV. You can launch any video player, browser, or online movie app, and the image will be mirrored. Image quality in this mode depends on the phone's processor and Wi-Fi speed, as the device encodes the video stream in real time.
What to do if the code does not appear?
Sometimes the security system requires manual confirmation. Go to the AirPlay settings on your TV and select "Require code" -> "First time only." This will make it easier to reconnect in the future.
Using the LG TV Plus app to stream
If for some reason the native AirPlay is unstable or your TV model is an older generation (before 2018), the official app will come to the rescue. LG TV PlusThis tool provides advanced control over your TV and allows you to stream media content stored on your smartphone or accessed via a link.
Download the app from App Store and launch it. The program will automatically scan the network and find compatible devices. Select your TV from the list. For the "Media Play" feature to work, make sure the corresponding app is running on the TV or the input is in data reception mode. The program interface allows you to manage files by category: videos, photos, and music.
The main advantage of this method is the ability to control playback directly from your smartphone screen. You can use your phone as a remote, rewind videos, adjust the volume, and create playlists. This is especially convenient when you need to quickly find a specific movie in a large online movie library without scrolling through long lists on your TV.
It is important to note that the application LG TV Plus The system may not support streaming protected content from some streaming services due to DRM (copyright management) policies. In such cases, the system may display a black screen with the sound turned on or return a playback error.

Broadcast via browser and DLNA servers
For more advanced users who want to stream video files downloaded from the internet or content from browsers without built-in Cast functionality, there are DLNA servers. TVs LG have a built-in media player capable of receiving streaming video via the protocol DLNAYou'll need a server app on your iPhone that will turn it into a data storage device.
Popular apps like VLC for Mobile or OPlayer have a built-in feature for streaming video to a TV. Once you've loaded a movie into such an app, you'll see a streaming icon (usually a rectangle with waves). Clicking on it will display a list of available devices. Select yours. LG TV, and playback will start directly, bypassing the phone screen, which saves battery power.
⚠️ Note: When using DLNA, your phone acts as a server. Don't lock your smartphone's screen or minimize the app while watching, otherwise the data transfer may be interrupted and the movie will stop.
This method is ideal for viewing video files in formats that aren't supported by the TV's built-in player but can be decoded by the phone app. In this case, the phone takes care of the labor-intensive work of decoding the video stream and sends the finished image to the TV.
Troubleshooting connection and buffering issues
Even with proper setup, users may encounter issues: video stutters, audio drops out, or devices fail to connect. One common cause is overloaded Wi-Fi from neighboring routers. If you live in an apartment building, the airwaves may be clogged, leading to lost data packets and buffering.
Try rebooting your router by unplugging it for 10-15 seconds. This will clear the device's cache and force it to select a less congested channel. Disabling other heavy traffic users also helps: stop downloads on computers or tablets while watching a movie.
If the problem persists, check your router's firewall or antivirus settings. Sometimes parental controls or attack protection features can block local ports used by protocols. AirPlay or DLNATemporarily disable these features for diagnostic purposes.
Third-party apps for advanced features
In the store App Store There are many utilities available such as Replica, TV Cast or Web Video CasterThey're useful when you need to stream content from sources that block standard output methods. For example, some websites prohibit video output via AirPlay but allow it through their native browser with the Cast feature.
The principle of such programs is simple: you open the app's built-in browser, go to the movie's website, and start the video. Then, press the connect button and select your TV. The app captures the video stream and redirects it to the device. LGThis is a workaround that often helps when watching online TV or videos from non-standard sources.
However, be aware of advertising. Free versions of such apps are often overloaded with banner ads that can interfere with controls. Paid versions are free of these drawbacks and offer a more stable compression codec, improving image quality.
Is it possible to play games on your phone through your TV?
Technically, yes, via screen mirroring. However, due to input lag over Wi-Fi, this is only suitable for turn-based strategy games. For shooters or racing games, the latency will be too high.
Optimizing image and sound quality
Once the connection is successful, it's important to configure the output settings for maximum comfort. On TVs LG There are often picture modes such as "Movie," "Game," or "Eco." When watching movies over Wi-Fi, it's best to select "Movie" or "Cinema" mode, which provides the most accurate color reproduction and smooth motion.
Please pay attention to the aspect ratio. When broadcasting with iPhone The image may not fill the entire 16:9 screen, leaving black bars on the sides, as smartphone screens are often more elongated. This is normal. Stretching the image will distort the proportions. Use the zoom in your TV settings (16:9 Just Scan or Original) to remove unnecessary fields, if any.
As for audio, when connecting via AirPlay, the audio is transmitted digitally. If you have an external speaker system or soundbar connected to your TV via ARC/eARC, the sound will be output through them. Make sure your TV's audio settings are set to output to an external system, not to the built-in speakers.
Why does the video jerk when watching online movies?
Most often, this is due to insufficient internet speed or an overheating phone processor. Try reducing the video quality in your player (for example, from 4K to 1080p) or rebooting your router.
Is it possible to connect an iPhone to an old LG TV without Smart TV?
Without a built-in Wi-Fi module and Smart TV, you won't be able to connect your phone directly. You'll need to purchase an external adapter, such as an Apple TV or Chromecast adapter, which plugs into the HDMI port.
Is mobile internet traffic used when connected to Wi-Fi?
No, if your phone is connected to your home Wi-Fi network, all traffic goes through your home network. Make sure "Cellular Data" is not enabled in your iPhone settings to ensure backups are performed if your Wi-Fi connection is weak.
