Modern smartphone users are often faced with the need to broadcast content from a small screen to a large panel. The Screen Share function (or screen mirroring) is a de facto standard for TVs LG supported webOS. This allows you to view photos, videos and even play mobile games on your home theater without the use of unnecessary wires.
The device synchronization process is based on technology Miracastthat creates a direct Wi-Fi connection between gadgets. Unlike Chromecast, it doesn't require a router, although having a shared network makes finding devices much easier. It is important to understand that the quality of the transmission depends on the power of the wireless module of your Androidsmartphone and the firmware version of the TV.
In this article we will analyze in detail the algorithm of actions for a successful connection, consider the features of the application LG TV Plus and analyze typical errors that occur when trying to start broadcasting. You will learn not only how to run mirroring, but also how to optimize settings to minimize image delays.
Preparing equipment and checking compatibility
Before you begin setup, you need to make sure that both devices support the required communication protocols. Most TVs LG, released after 2014, have a built-in module Wi-Fi Direct. However, older models in the budget segment may require connecting an external adapter.
On the smartphone side, the situation is similar: the wireless broadcast function must be hardware supported by the chipset. Go to your phone's settings and find the "Connections" or "Display" section. If there is a “Broadcast”, “Smart View” or “Projection” item there, your device is ready to use.
⚠️ Attention: Make sure that the function of receiving external signals is turned on on your TV. In some models LG mode
Screen Shareneeds to be activated manually through the list of signal sources or in the application menu.
Operating system interfaces are constantly updated, and the menu layout may differ depending on the version Android or webOS. Check the current names of items with the official documentation of your specific TV model, as the manufacturer may change the logic of the menu in new firmware.
- 📱 Check the presence of a Wi-Fi module in your smartphone.
- 📺 Make sure that the TV is connected to the power supply and turned on.
- 📶 It is advisable that both devices were in the same room for a stable signal.
- 🔄 Update the TV firmware to the latest available version.
Setting up a Wi-Fi network and discovery mode
The most reliable way to ensure stable data transfer is to use a shared home network. Connect your TV and smartphone to the same router. This will reduce the load on the direct connection and allow you to use the Internet on your phone during the broadcast.
If using a router is not possible, activate the mode Wi-Fi Direct. On the TV LG go to the network settings menu. Select "Wi-Fi Direct" and turn it on. The TV will begin searching for available devices or become visible to them.
Settings → Network → Wi-Fi Direct → OnOn a smartphone, the process may differ depending on the manufacturer's shell. In pure Android this menu is located in the “Connected devices” section. In shells One UI from Samsung or MIUI from Xiaomi the function is often placed in the “curtain” of quick settings called Smart View or Broadcast.
To reduce latency when playing games, disable the guest network on the router and use the 5 GHz band if both devices support it.
Sometimes automatic search does not work due to the security settings of the router's firewall. In this case, try temporarily disabling client isolation (AP Isolation) in the router settings. This will allow devices to see each other within the local network.
Step-by-step guide for connecting through built-in tools
After checking the networks, you can begin direct pairing. The algorithm of actions is intuitive, but requires consistency. First, we activate the signal reception on the TV, then we initiate the search from the smartphone.
On the remote control LG press the button Input or “Input”. From the list of sources, select Screen Share or Screen Mirroring. The message “Waiting for connection” will appear on the screen.
☑️ Connection algorithm
Now take your smartphone. Open the quick settings panel and click on the broadcast icon. The broadcast will begin scanning. When your TV's name appears in the list (for example, LG webOS TV), tap it.
You may be asked to confirm the connection on the TV screen. Use your remote to select Accept or Allow. After this, the image from the phone should be displayed on the large screen with minimal delay.
| Action | Device | Result |
|---|---|---|
| Mode activation | LG TV | Starting the discovery service |
| Searching for devices | Android smartphone | Scanning available receivers |
| Pairing | Both devices | Setting up a secure channel |
| Broadcast | Smartphone → TV | Duplicating image and sound |
⚠️ Attention: When connecting for the first time, the system may request permission to access data. Do not cancel this request, otherwise the video stream will be blocked by the security system. Android.
Using the LG TV Plus app for advanced features
The built-in tools are good for simple duplication, but the app LG TV Plus (formerly known as LG SmartShare) offers deeper control. It allows you not only to broadcast the screen, but also to use your smartphone as a control panel, as well as transfer files directly to the TV’s media library.
Download the official application from Google Play Market. Once installed, launch it and grant all the requested permissions, especially local network and storage access. The application will automatically find the TV on the network.
In the app interface, select the “Broadcast” tab or the screen icon. Here you can choose Mirror mode or transfer a specific media file. The advantage of this method is the ability to minimize the application on the phone without interrupting video playback on TV.
Why may the application not see the TV?
If the LG TV Plus application does not find the TV, check whether the antivirus on your smartphone is blocking local connections. Also make sure that the “Mobile TV On” function is enabled on the TV in the network settings.
The functionality of the application depends on the version webOS. On new models, the integration is deeper, allowing you to display phone notifications on the TV screen. On older versions of the software, the functionality may be limited only to transferring photos and videos from the gallery.
Broadcasting content from specific applications (YouTube, Netflix)
The technology Google Cast, which is built into many popular applications, deserves special attention. Unlike full screen duplication (Screen Share), here the TV itself downloads a video stream from the Internet, receiving only a playback command from the phone.
This radically reduces the load on the smartphone's battery and frees it up for other tasks. You can minimize YouTube or lock your phone, and the video on your TV will continue to play. To do this, the video application should have a rectangle icon with waves.
Click on the icon Cast in the corner of the video player. Select your TV LG from the list. It is important that in this scenario, both devices must be connected to the same Wi-Fi network; a direct Wi-Fi Direct connection will not work here.
- 🎬 Open the video in the YouTube or Netflix application.
- 📡 Click on the broadcast icon in the player.
- 📺 Select your LG TV in the list devices.
- ▶️ The video will start playing directly on the TV.
Using the built-in Cast button in applications saves phone battery power and provides higher picture quality than full screen mirroring.
Some streaming services block screen mirroring due to copyright protection (DRM). In such cases, a black screen with sound when using Screen Share is normal. The only solution is to use the native Cast button inside the application.
Troubleshooting and optimizing the connection
Even with proper configuration, users may encounter artifacts, audio desync, or connection dropouts. Most often, the problem lies in an overloaded Wi-Fi airwave or outdated software.
If the image is slow, try rebooting the router and both devices. Switching the TV to another Wi-Fi channel that is less congested by neighboring networks also helps. You can do this manually in the router settings.
If the “Unable to connect” error occurs, clear the network settings cache on your phone. Go to Settings → Applications → Show system → Android system interface (or equivalent) → Storage → Clear cache.
⚠️ Attention: Resetting the network settings on your phone will delete saved passwords from all Wi-Fi networks. Be prepared to re-enter them after the procedure.
If the problem persists, check the date and time on both devices. Clock desynchronization can lead to security certificate errors when establishing a secure connection Miracast.
Frequently asked questions (FAQ)
Why doesn't the LG TV see my phone in the list of devices?
Make sure that both devices are connected to the same Wi-Fi network. Check if the client isolation mode is enabled on the router. Also try restarting the Screen Share service on your TV by closing and opening the application again.
Is it possible to transfer sound only to the TV and leave the image on the phone?
It is difficult to do this using standard Android tools. Usually either everything or nothing is transmitted. However, some players have a function for selecting an audio output device (Bluetooth or Wi-Fi), but video may not be broadcast.
Does the Screen Share connection affect the Internet speed?
When using Miracast mode (direct connection), the Internet on the phone may temporarily turn off or work unstable, since the Wi-Fi module switches to access point mode. When using a router, the speed may decrease slightly due to the load on the channel.
How to disable screen broadcasting?
On your phone, open the notification panel and click the “Disable” or “Stop” button in the broadcast widget. You can also simply turn off the TV or switch it to another signal source (HDMI, TV channel).
