Modern Smart TV from the company LG While mobile devices offer users a wide range of multimedia entertainment options, built-in browsers or apps aren't always easy to navigate. It's often easier and faster to launch content directly from a mobile device, whether it's Android or iOSWireless data transmission technologies allow you to broadcast images and sound to a large screen without the use of unnecessary cables.
The main condition for successful synchronization is the stable operation of the home network. Wi-Fi router It acts as the central hub through which data packets are exchanged between the gadget and the TV. It's important to understand that transmission speed directly impacts image quality and the absence of lag when playing high-definition video.
In this article, we will examine in detail all available methods, from native functions LG webOS to third-party applications. You will learn how to set up a DLNA server, use the protocol Miracast for full screen cloning, as well as how to organize streaming via AirPlay 2 for equipment owners Apple.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your hardware meets the minimum requirements. Both devices must be on the same Wi-Fi subnet, meaning they must be connected to the same router. If you have a dual-band router, make sure your phone and TV are connected to the same frequency (usually 2.4 GHz or 5 GHz), although modern routers often combine them into a single network.
For TVs LG with the operating system webOS Version 3.0 and above (2016 models and newer) have most features built in by default. Older models may require installing a special app from LG Content Store, such as Smart ShareCheck that your TV software is up to date.
⚠️ Note: If you're using a guest Wi-Fi network or a corporate network with AP Isolation, devices won't be able to "see" each other. In this case, streaming is impossible without changing your router settings.
It's also worth considering the channel's bandwidth. To transmit video in resolution 4K UHD A stable speed of at least 25 Mbps is required. If the network is overloaded by other devices, image artifacts or audio desynchronization may occur.
Screen Share (Miracast) for Android and Windows
The most universal way is to use technology Miracast, which is on TV LG implemented through the function Screen ShareThis method allows you to mirror your smartphone's screen completely to your TV, making it ideal for displaying photos, videos from your gallery, or even games.
To get started with the remote control LG Magic Remote you need to press the button with the image of a house or the button Inputto open the input menu. From the list of available signal sources, select Screen Share or Connecting to a mobile deviceA waiting for connection message will appear on the TV screen.
On a smartphone with an operating system Android The steps may vary slightly depending on the model:
- 📱 Open the quick settings panel (swipe down from the top) and find the "Cast", "Smart View" or "Screen projection" button.
- 📱 Turn on the device search function and wait for your TV's name to appear LG on the list.
- 📱 Click on the TV name and confirm the connection if a permission request appears on the TV screen.
Once paired successfully, the smartphone's image will appear on the large screen. It's important to note that when using this method, the phone's screen must remain on, as this can drain the battery quickly.
☑️ Check before connecting Miracast
Using the LG TV Plus app for advanced control
Official app LG TV Plus (formerly known as LG TV Remote) provides a deeper level of integration than standard Screen ShareIt allows you to not only stream photos and videos from your phone's memory, but also use your smartphone as a touch control panel (Magic Mobile).
To get started, you need to download the application from Google Play or App StoreAfter installation, launch the program and follow the on-screen instructions. The app will automatically scan the network and offer a list of available TVs.
The application's functionality includes:
- 📷 Broadcast photos and videos saved in the device gallery.
- 🎮 Use your phone as a gaming keyboard or joystick for simple games on TV.
- 🎬 Video playback control with rewind and subtitle selection.
The app's interface is intuitive. The "Media" tab lets you select files by type (Photos, Videos, Music). When you select a file to play, the TV will decode the stream for you, reducing the load on your smartphone and saving battery life.
What should I do if the app doesn't detect the TV?
If the automatic search doesn't yield any results, try manually adding the device by IP address. You can find the TV's IP address in the TV's network settings (Network -> Wi-Fi Connection -> Advanced Wi-Fi Settings). In some cases, rebooting the router helps.
Broadcast for iPhone and iPad owners (AirPlay 2)
For equipment owners Apple I was the luckiest one, because modern TVs LG (2019 and newer models) have built-in protocol support AirPlay 2This means that no additional apps or hacks are needed for streaming.
The connection process is as simple as possible. Make sure that your iPhone or iPad connected to the same Wi-Fi network as the TV. Open the content you want to show (video in the gallery, movie in YouTube or even the entire screen).
Tap the Screen Mirroring icon (two rectangles) in the Control Center or tap the icon AirPlay inside the app. Choose your LG Smart TV from the list. A confirmation code may appear on the TV screen, which you must enter on your smartphone.
Technology AirPlay 2 It provides high stability and allows you to control playback from your phone without interrupting the stream. It also supports multi-room audio, allowing you to sync your TV's sound with other speakers. HomePod or AirPlay-compatible devices in the home.
Comparison of connection methods and their characteristics
To help you choose the right method, we've prepared a comparison table of the main streaming methods. Each has its own advantages depending on the type of content and the device used.
| Method | Device type | Image quality | Latency |
|---|---|---|---|
| Screen Share (Miracast) | Android / Windows | Depends on Wi-Fi signal | Average (noticeable in games) |
| LG TV Plus | Android / iOS | High (up to 1080p/4K) | Low (for media) |
| AirPlay 2 | iOS (iPhone/iPad) | Very High (4K HDR) | Minimum |
| DLNA (Everything Plays) | Any (files) | Maximum (without compression) | Missing (file) |
As you can see from the table, specialized applications or are best suited for viewing movies from the gallery AirPlay, as they provide better picture quality. Miracast It is more suitable for demonstrating an interface or web pages, where the image on the screen is important, and not the quality of file decoding.
Setting up a DLNA server to play files
Protocol DLNA (Digital Living Network Alliance) is a standard for transmitting multimedia content within a home network. Unlike screen mirroring, the TV itself acts as a renderer, receiving a data stream from the phone server.
On phones Android This feature is often built into a standard player or file manager. For example, in the "All Playing" application (AllShare or similar) or even in the standard "Gallery" by pressing the "Broadcast" button (screen icon with arrows).
Algorithm of actions:
- 📂 Open a video file or photo folder on your smartphone.
- 📂 Click the "Stream" button or select a device from the list of available renderers.
- 📂 Select your TV LGThe file will start playing on the TV, and the phone can be used for other tasks or put aside.
The advantage of DLNA is that the TV uses its own resources for video decoding. This allows for playback of large, high-bitrate files that a phone might otherwise struggle to handle when directly outputting via HDMI or Miracast.
⚠️ Important: File formats must be supported by your TV. If the TV doesn't recognize the file or displays "unsupported format," try using a third-party player on your phone (such as VLC), which has a built-in DLNA server and can stream compatible formats on the fly.
Solution and troubleshooting
Despite the ease of setup, users often encounter technical issues. One of the most common is that the TV doesn't appear in the list of available devices. In 90% of cases, this can be resolved by ensuring both devices are connected to the main network, not the guest network, and are in the same frequency band.
Another common problem is desynchronization of audio and video or intermittent stuttering. This indicates an unstable signal. Wi-FiTry moving closer to the router or rebooting it. Disabling other devices that actively consume bandwidth (game downloads, torrents) also helps.
If the connection keeps dropping:
- 🔄 Restart your TV by completely unplugging it from the power outlet for 10-15 seconds (to relieve static electricity).
- 🔄 Delete the Wi-Fi network profile on your TV and reconnect using the password.
- 🔄 Check the date and time settings on your phone and TV—they must match, otherwise security certificates may block the connection.
In some cases, the problem lies with antivirus software or a firewall on your router, which is blocking local connections between devices. Check your router's security settings and ensure the local area network (LAN) is set to "Trusted."
Why doesn't my LG TV detect my phone via Wi-Fi?
There could be several reasons for this: devices on different networks (for example, one on 2.4 GHz, the other on 5 GHz with name separation), access point isolation mode enabled on the router, outdated firmware on the TV or phone, or the connection being blocked by an antivirus program.
Is it possible to play games on a phone and output them to a TV?
Yes, via Screen Share (Miracast). However, due to input lag, this method is only suitable for turn-based strategy games or trivia games. For fast-paced shooters or racing games, a lag of 100-200 ms will make the experience uncomfortable.
Is the sound transmitted to external speakers when a phone is connected?
When using AirPlay 2 or DLNA, audio is transmitted through the selected output device (TV or connected speakers). When using screen mirroring (Miracast), audio is usually transmitted along with the video stream to the TV. If a soundbar is connected to the TV via HDMI ARC, audio will be transmitted to it.
How to improve picture quality during broadcasting?
Use the 5 GHz band for Wi-Fi, as it's less congested and offers faster speeds. Close background apps on your phone. For video files, use DLNA or AirPlay instead of full screen mirroring so the TV can decode the video itself.
