Modern Smart TV from the company LG It transforms a regular screen into a multimedia center, but the device's full potential is only realized when synced with a mobile device. Transferring photos, videos, or even mirroring the entire smartphone screen to a larger panel is a standard feature available to every user. However, despite its apparent simplicity, the setup process often raises questions due to differences in operating systems and firmware versions.
The main advantage of a wireless connection is the absence of unnecessary wires that spoil the interior and restrict freedom of movement. The key to successful synchronization is that both devices are on the same local Wi-Fi network., ensuring stable data transfer without lag. In this article, we'll take a detailed look at all available connection methods, from built-in protocols to specialized apps.
Before you begin setting up, make sure your TV supports Smart TV technology and has an active internet connection. Owners of models with the operating system webOS have the most tools for interacting with smartphones. Let's look at the main ways to display content on the big screen.
Preparing equipment and checking the network
The first step in the setup process is to properly prepare your infrastructure. Make sure your router is broadcasting on the 5 GHz frequency, if possible, as this will provide higher throughput for 4K video. If your router is dual-band, it's a good idea to connect your TV as well. LG, and the smartphone to the same frequency, although modern routers often combine ranges into one network.
Check your TV's software version, as older firmware versions may not support new media standards. To do this, go to the settings menu and select General and find the item About TVA software update function is available here, which is recommended to be performed before starting the setup.
⚠️ Attention: If you have "Guest Network" mode enabled on your router, devices may not be able to see each other due to client isolation. For Miracast or DLNA to work properly, make sure both devices are connected to the main network.
It's also worth checking whether AP Isolation mode is enabled on your router, which prevents devices within the network from exchanging data. In most home networks, this setting is disabled by default, but in office or complex setups, it can block your phone from finding the TV.
Using the built-in Screen Share (Miracast) feature
The most common way to transmit images is through technology Miracast, which is on TV LG Often called Screen Share, this method allows you to mirror your smartphone's screen to your TV in real time without the need for additional apps. The technology operates on the Wi-Fi Direct protocol, so no internet connection is required to transmit the image; only an active Wi-Fi module is required.
To start working, press the button with the login icon on the remote control or find the program in the list of launcher applications Screen Share (in new models it may be called Device Connector). Once launched, a connection window will appear on the screen. On an Android smartphone, open the notification shade and find the "Cast," "Smart View," or "Wireless Monitor" function.
The search process may take anywhere from a few seconds to a minute. Once your device's name appears in the list of available devices, LG TV, select it. A connection confirmation prompt may appear on the TV screen, which you'll need to accept using your remote.
☑️ Screen Share connection algorithm
It's worth noting that your smartphone may heat up when using Miracast, as the video encoding process occurs in real time. Furthermore, if you minimize an app on your phone or receive an incoming notification, this will also be reflected on the TV screen.
Stream media via DLNA and Smart Share
If your goal is not to duplicate the screen, but simply to show your friends photos from the holiday or play a movie from the phone’s memory, it is better to use the protocol DLNAIn the ecosystem LG the application is responsible for this Smart Share (or simply the built-in media player in newer versions of webOS). This method is less demanding on the smartphone's resources, as it only acts as a remote control, while the TV itself handles the decoding.
To use this method, launch the app on your TV Photos and videos or Smart ShareSelect your smartphone from the list of sources. On Android devices, it's often enough to open the gallery, select a video, tap the "Cast" button (the rectangle icon with waves), and select your TV.
| Parameter | Miracast (Screen Share) | DLNA (Smart Share) | LG TV Plus app |
|---|---|---|---|
| Transmission type | Full screen mirroring | Only media files (photos, videos, music) | File management and streaming |
| Phone addiction | High (screen should be lit) | Low (you can minimize the application) | Average |
| Video quality | Depends on Wi-Fi signal | Maximum (native) | Depends on the file format |
| Sound | Broadcast on TV | Broadcast on TV | Broadcast on TV |
The advantage of DLNA is its support for subtitles and more stable playback of large files. The TV decodes the stream itself, saving battery life. However, the file navigation menu may not be as user-friendly as on the smartphone itself.
Connecting iPhone and iPad (AirPlay 2)
Equipment owners Apple for a long time were limited in their ability to connect to TVs LG, but with the release of webOS 4.0 and later, the situation has changed dramatically. Now there is native support AirPlay 2 built right into your TV system, allowing you to stream content without purchasing an Apple TV box.
To activate the function on your TV, go to Settings → Connection → AirPlay and make sure the switch is enabled. On an iPhone or iPad, simply open the Control Center (swipe down from the top-right corner or up from the bottom, depending on the model) and tap the "Screen Mirroring" icon.
Select yours from the list LG Smart TVIf this is your first time using the TV, a code will appear on the TV screen that you'll need to enter on your smartphone to pair. After this, your phone's screen will be fully mirrored on the TV. You can launch any apps, games, or presentations, and the image will be transmitted with minimal lag.
⚠️ Attention: AirPlay 2 is only available on LG models released in 2019 and later, as well as some updated 2018 models. Native AirPlay does not work on older TVs running webOS 3.5 or earlier.
Besides mirroring, many video players (YouTube, Vimeo, Netflix) have a built-in Cast button. Clicking it sends the video link directly to your TV, which will automatically download the stream. This frees up your phone for other tasks and saves battery life.
The official LG TV Plus app
For those who prefer to use specialized software, the company LG developed an application LG TV PlusIt's available for Android and iOS and offers advanced control features. It lets you not only stream photos and videos but also use your smartphone as an advanced remote control with a touchpad and keyboard.
After installing the app on your phone and launching it on your TV, the devices will automatically find each other. The program's interface allows you to create playlists, manage the playback queue, and even display text messages on the screen, which is convenient for karaoke or presentations.
Why might the app not see the TV?
If LG TV Plus isn't finding your TV, check the permissions in your smartphone settings. The app requires access to your local network (Local Network) and geolocation (for Android), as these details are used to detect devices on your Wi-Fi network. Also, make sure your antivirus software isn't blocking local connections.
A key advantage of the app is the ability to control multiple TVs if they are connected to the same network. This is especially useful for offices or restaurants where content needs to be streamed to multiple screens.
Solving common connection problems
Despite the technology's refinement, users may encounter difficulties. The most common issue is that the phone simply doesn't see the TV in the list of available devices. In this case, try rebooting the router, as a temporary glitch in the ARP address table may be preventing detection.
Another common cause is the use of different Wi-Fi bands. If the router is distributing two networks (for example, Home_2.4 And Home_5G), make sure both devices are connected to one of them. Some routers have an "AP Isolation" or "Client Isolation" setting that should be disabled.
If the image flickers or the sound drops out when connecting via Miracast, this indicates a weak signal. Try moving the router away from the microwave or other sources of interference. It's also worth checking that your TV isn't in power-saving mode, which could be interrupting the connection.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone to an LG TV without a Wi-Fi router?
