Wireless image transmission has become a standard for modern home entertainment, allowing you to instantly stream content from your smartphone to the big screen. Owners of Korean brand equipment are often looking for information on screen share lg how to connect androidto enjoy movies, photos or games without the use of unnecessary wires. The technology Miracastimplemented in LG TVs called Screen Share provides a stable connection and high picture clarity.
The process of synchronizing devices is intuitive, but requires compliance with certain network conditions and a sequence of actions in the menu of both gadgets. With the right setup, you can control your media directly from your phone, turning your TV into a powerful entertainment center. Below we will analyze in detail all the stages of connection, possible problems and alternative methods of broadcasting.
Technological basics of wireless connection
The Screen Share function is based on a protocol Miracast, which allows you to transmit a high-resolution video signal via Wi-Fi Direct. This means that the devices create a direct connection to each other, bypassing the home router to transmit the video stream itself, although discovering the devices often requires a shared local network. Unlike outdated standards, this method provides minimal latency, which is critical when watching dynamic video.
TVs LG with webOS support have a built-in signal receiving module, which is activated through a special application. Smartphones based on Android are also equipped with the necessary drivers, but the name of the function may differ depending on the shell manufacturer. For example, on Samsung devices it is called Smart View, and on Xiaomi it is called Wireless Monitor.
The quality of the transmission depends on several factors, including the version of the Wi-Fi module and the air load. Modern models support resolution 1920×1080 and even 4Kif both devices meet the standard requirements. It is important to understand that the function does not require an Internet connection; it is enough that the devices are in line of sight of the radio signal.
⚠️ Attention: If your router operates in the 5 GHz band with a channel width of 80 or 160 MHz, some older smartphones may not see the TV. In this case, try switching the router to 2.4 GHz mode or using Wi-Fi Direct mode without the participation of the router.
For the best picture quality, place the router approximately in the middle between the TV and smartphone to avoid shielding the signal by concrete walls.
Preparing the LG TV to receive the signal
Before trying to connect devices, you need to activate the standby mode on the TV side. On the remote control, find a button with the text Input or a square icon with an arrow. In the list of signal sources that opens, select Screen Share. On new models with webOS 4.0 and higher, this application may be located in the ribbon of launched apps at the bottom of the screen.
After launching the application, a connection waiting interface will appear on the screen. This displays the device name that will be visible to your phone and the connection status. Some firmware versions require you to confirm connection permission when a new gadget is first detected.
Make sure that the function Wi-Fi on the TV. Even if you are using a cable Internet connection, the wireless module must be active for Screen Share to work. You can check this in the section: Settings → Network → Wi-Fi Connection data-i="56">Make sure that the "Waiting for connection" status is on Settings → Network → Wi-Fi Connection.

Configuring an Android smartphone for broadcasting
The algorithm of actions on the side of the mobile device may vary slightly depending on the model, but the general the principle remains the same. Open the quick settings panel by swiping down from top to bottom and find the broadcast icon. If you don't see it right away, you may need to tap the pencil or three dots to edit the list of tiles.
After tapping the broadcast button, the phone will begin scanning available devices within range. When your TV appears in the list LG, tap its name. The system will ask you to confirm the connection, and after a few seconds the image from the phone screen will be displayed on the TV.
For users of pure Android or devices with a close-to-stock shell, the path often lies through the settings menu. Go to section Connected devices → Connection settings → Broadcast. Here you can force the function and select the display mode: screen duplication or expanding the workspace.
| Smartphone manufacturer | Function name | Menu path | Features |
|---|---|---|---|
| Samsung | Smart View | Notification curtain | Support for TV remote control |
| Xiaomi / Redmi | Wireless monitor | Settings → Connection and sharing | There may be a delay of games |
| Huawei / Honor | Projection | Notification curtain | High connection stability |
| Google Pixel | Broadcasting | Settings → Connected devices | Minimalistic interface |
Alternative connection methods through applications
If the standard function for some reason does not work or you want to get advanced functionality, you can use third-party solutions. The application TV Cast for LG WebOS allows you to broadcast not only the entire screen, but also individual video files, photos and web pages directly from your phone browser. This often provides better picture quality, since the TV itself decodes the stream.
Another popular option is to use the Google ecosystem. If your TV supports Chromecast built-in, you can use the cast button inside the YouTube, Netflix or Google Photos apps. In this case, the phone acts only as a control panel, and the video is downloaded by the TV directly from the network, which saves battery power on the smartphone.
For advanced users, it is possible to use the protocol DLNA. By installing a media server on your phone (for example, BubbleUPnP), you can open access to movie and music folders. The TV will see the phone as network storage and allow you to play content through the built-in player.
Why is the application better than the system function?
Third-party applications often have their own codecs, which allows you to play video formats that the standard Miracast protocol does not support, for example, specific MKV containers with rare audio tracks.
Troubleshooting and connection problems
The most common problem is that the phone does not see the TV in the list of available devices. In 90% of cases, this is due to the fact that the devices are on different subnets or one of them is connected to a guest Wi-Fi network. Make sure that both gadgets are connected to the same router and have access to the local network.
If the connection is established, but the picture freezes or disintegrates into pixels, the problem lies in an unstable signal. Try moving closer to the router or TV. It is also worth checking whether the Wi-Fi channel is overloaded by neighboring networks. In the router settings, you can try changing the broadcast channel to a less busy one.
Sometimes a complete reset of the network stack helps. Unplug the TV for 30 seconds, and reboot the wireless module on your phone by turning airplane mode on and off. After turning on the devices, try searching again.
⚠️ Attention: Antiviruses and firewalls on your smartphone may block the outgoing connection for broadcasting. If all else fails, temporarily disable network protection in your phone's security settings.
The stability of the connection directly depends on the distance to the router and the absence of physical obstacles between the signal transmitter and receiver.
Features of working with different versions of webOS
The interface and logic of Screen Share have changed with the release of new versions of the operating system TV. On older models with webOS 2.0 and 3.0, the application launched automatically when you tried to connect, and the device name was fixed. In new versions, starting with webOS 4.0, the user can set the name of the TV, which simplifies identification in the list of devices.
In the latest updates, LG added support for the standard AirPlay 2, which is important for iPhone owners, but also improved the stability of working with Android. If you have a newer model, make sure that all required protocols are enabled in your sharing settings. This is located in the menu Settings → Support → Home panel → Home panel access menu.
It is worth considering that older TV models may not support high-quality audio transmission when mirroring the screen due to channel bandwidth limitations. In such cases, it is recommended to use an external speaker system connected directly to the TV via the optical output.
If you often use the Screen Share function, add an application shortcut to the webOS main panel to launch it with one click of a button on the remote control.
Why is there no sound on the TV when connected?
Most often, the sound remains on the phone due to Bluetooth settings or the choice of output device at the time of connection. When you start broadcasting, check the pop-up window on your smartphone and make sure that the checkbox next to “Broadcast audio and video” is checked. If the sound is still coming from the phone, go to the multimedia settings and select the TV as the output device.
Is it possible to play games on the TV via Screen Share?
Technically this is possible, but it is not recommended for dynamic projects. Input lag for wireless transmission ranges from 100 to 300 ms, which makes shooting or racing uncomfortable. For static games, quizzes or turn-based strategies, the delay will not be noticeable and will not spoil the impression.
How to turn off the broadcast without turning off the TV?
To correctly end the session, you do not need to turn off the TV with the remote control. On your smartphone, just press the mute button in the broadcast menu or minimize the Screen Share application. On some phone models, it is enough to lock the screen, and the connection will be disconnected automatically after a minute.
Does broadcasting affect Internet speed?
When using Miracast mode (screen mirroring), Internet traffic is practically not consumed, since data is transferred directly between devices. However, if you use DLNA mode or the built-in Chromecast to stream video from online cinemas, the TV will consume traffic from your home network, which may reduce the speed on other devices.
