Modern televisions LG While they are powerful multimedia centers, their functionality can be limited by the operating system interface or a lack of necessary apps. There's often a need to stream content from a smartphone or tablet to a larger screen, whether it's family photos, videos from the gallery, or live streaming from a website. Wireless connection Wi-Fi allows you to do this quickly and without unnecessary wires, ensuring stable high-speed data transfer.
The connection process depends on your TV model and mobile device operating system. Owners of supported devices Smart TV have access to advanced video streaming protocols such as Miracast or AirPlay 2. For older models without built-in Wi-Fi, there are alternatives using external adapters or a local network. In this article, we'll cover all the available options in detail so you can enjoy content on the big screen without lag.
Before setting up, make sure both devices are on the same network. This is critical, as the router acts as an intermediary, routing data packets between the device and the TV. Ignoring this requirement may result in an endless search for devices or no results at all.
Equipment preparation and compatibility testing
The first step is to verify the technical specifications of your equipment. Not all TVs LG support direct wireless connection, especially models released more than 10 years ago. You need to check that the device's specifications state support for these standards. Wi-Fi Direct or technology Screen ShareIf your TV is a "regular" model (without Smart TV), you will need an additional Wi-Fi adapter or media player.
It's also important to check the network connection status. Even if the TV has a built-in module, it may be disabled in the settings or in sleep mode. Go to the network settings menu and make sure the connection status is active. For proper operation, it is recommended to use a frequency 5 GHz, if your router supports dual-band mode, as this will provide lower latency when transmitting high-definition video.
⚠️ Note: When using a guest Wi-Fi network (Guest Network) on a router, devices may be isolated from each other. In this mode, streaming to a TV will not work, as DLNA and Miracast discovery protocols require direct line of sight between devices on the local network.
The mobile device must also meet certain requirements. For Android smartphones, the system version must be at least Android 4.2, although for stable operation of modern codecs it is better to have Android 8.0 and above. Devices Apple AirPlay 2-enabled devices require iOS 12.3 or later. Make sure your phone's wireless module is enabled and local network access permissions are not restricted by security settings.
Using LG's built-in Screen Share feature
The most common method for TV owners LG with the operating system webOS - using a native application Screen ShareThis method is based on the protocol Miracast, which allows you to stream your smartphone's screen in real time. You don't need to install any additional apps on your TV; simply activate the feature in the menu.
To start the process, take the remote control and press the button Input or find the shortcut in the launcher's main menu Screen ShareAfter launching, a connection message will appear on the screen. Some models may require connection confirmation from the remote control when the smartphone attempts to establish a connection. This is a security measure to prevent unauthorized access to your screen.
☑️ Check before connection
On your Android smartphone, open the quick settings panel (the drawer) and find the "Cast," "Smart View," or "Wireless Monitor" feature. The name may vary depending on the device manufacturer (Samsung, Xiaomi, Huawei). After scanning the network, your TV should appear in the list. LGClick on it and the image will be duplicated on the big screen.
Transmission quality depends on signal strength. If you notice audio and video out of sync or image artifacts, try moving your smartphone closer to the router. The Miracast protocol is sensitive to interference, especially in apartment buildings where the airwaves are clogged with signals from neighboring networks.
Connecting iPhone and iPad via AirPlay 2
For equipment owners Apple I was luckier, since many modern TVs LG support technology AirPlay 2 Natively. This allows you to not only mirror your screen, but also display content from apps, control playback from your phone, and even use your TV as a second monitor for your Mac. For this feature to work, your TV must support the protocol, which is required for 2019 and newer models.
The connection process is extremely simple. Open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom, depending on your model). Tap the Mirroring icon (two rectangles). Select your TV from the list that appears. 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.
The advantage of AirPlay 2 is the ability to stream audio to your home audio system. HomePod or a soundbar, syncing it with the video on your TV. A "Picture-in-Picture" mode is also supported, allowing you to use your phone while the video plays on the big screen. However, keep in mind that if you're actively using your phone, the streaming may be interrupted by notifications.
Streaming via the LG TV Plus app
If standard methods don't work or you need advanced management functionality, a custom application LG TV Plus will be a great solution. It is available for platforms Android And iOS It allows you to not only stream photos and videos from your gallery but also use your smartphone as an advanced remote control. The app is especially useful when the remote's native keyboard is inconvenient for entering text when searching on YouTube or the browser.
After installing the app, launch it and follow the on-screen instructions. The program will automatically scan the network and offer a list of available TVs. Select yours. LG and confirm the pairing on the TV screen. The app interface includes tabs for transferring media files, controlling playback, and even a keyboard.
One of the app's useful features is the ability to transfer files of certain formats that may not be supported by the phone's native OS. For example, you can open a video file in a third-party player on your phone and send it directly to the app using the "Share" menu. LG TV Plus for display on the screen.
What should I do if the app doesn't find my TV?
Make sure your phone and TV have the latest app and firmware versions installed. Also, check to see if your smartphone's antivirus software is blocking access to the local network. In rare cases, resetting the TV's network settings via General -> Network -> Reset Connection may help.
Comparison of connection methods: characteristics table
To choose the best method, it's important to understand the differences between technologies. Below is a comparison table to help you choose the right connection method based on your needs and equipment.
| Characteristic | Miracast (Screen Share) | AirPlay 2 | DLNA (Media Server) |
|---|---|---|---|
| Transmission type | Full screen mirroring | Duplicate or duplicate application content | Media files only (photos/videos) |
| Latency | Medium/High | Low | Absent (streaming) |
| Sound | Transmitted with video | Separate management | Transferred with the file |
| Compatibility | Android, Windows | iOS, macOS | All platforms |
As you can see from the table, it is better suited for games or demonstrating the interface. Miracast, despite the possible delay. For viewing movies from the iPhone gallery, it's ideal AirPlayIf your goal is simply to show photos to relatives, then the universal protocol DLNA will be the most stable and easy to use, as it does not require a constant connection of screens, but only streaming data.
It's worth noting that when using DLNA, the TV acts as a renderer and the phone acts as a controller. This means you can control playback from your phone, but the file itself is transferred directly from the router (or server) to the TV, without loading the smartphone's processor. This helps conserve battery life on your mobile device.
Setting up DLNA and local media servers
For users storing large video collections on a computer or NAS storage, setting up a DLNA server is important. TVs LG They have a built-in media player that can access shared folders on the local network. This allows you to watch large files (4K, HDR) without compression and quality loss, which inevitably occurs when streaming your screen wirelessly.
On a Windows computer, you need to open "Media Streaming Settings" in Control Panel and allow access for your TV. LG. After that, in the "Media" menu on the TV (often called Photo & Video or Media Link) a source with the name of your PC will appear. You will be able to browse folders and launch files directly.
For more advanced users, it is recommended to install server software such as Plex or JellyfinThese programs don't just transfer the file; they can also stream it on the fly, adding subtitles, changing the audio track, or converting the format if the TV doesn't support the original codec. This turns a regular TV into a fully-fledged media center.
⚠️ Note: When transferring large files (over 20 GB) over Wi-Fi, buffering or stuttering may occur if the signal is unstable. For heavy 4K remastering with a high bitrate (over 80 Mbps), it is preferable to use a wired LAN connection from the TV to the router, even if the phone remains connected to the Wi-Fi network.
Troubleshooting connection and stability issues
Even with proper setup, glitches can still occur. One common issue is that the TV isn't visible in the list of available devices. In this case, try temporarily disabling your antivirus or firewall on your PC if you're setting it up from a computer, or check your router settings. Restarting all network devices often helps: turn off the router, TV, and phone, turn on the router, wait for it to boot up, then turn on the remaining devices.
Another common issue is audio desync. If the video plays but there's no sound or it's lagging, check the audio output settings on your phone. In some cases, switching the Bluetooth codec (if the audio is output to headphones) or resetting the audio settings on your TV can help. Also, make sure the "TV Only" audio output mode isn't enabled on your TV if you plan to use external speakers.
If none of these methods work, check for firmware updates for your TV. Manufacturers regularly release patches that fix bugs in network modules. You can update through the menu. Settings → All settings → General → About TV → Check for updates.
