LG’s modern webOS smart TVs and Xiaomi’s MIUI-enabled smartphones offer users a wide range of multimedia experiences. Wireless connectivity allows users to stream photos, videos, and even entire screen images across a large diagonal without the need for extra cables, especially for watching movies from online cinemas or showing presentations.
However, the process of synchronizing devices from different manufacturers often raises questions among users. Data protocols may differ, and hidden settings sometimes prevent the rapid detection of gadgets. In this article, we will discuss in detail all available methods, from built-in Android features to specialized applications.
You don't need a lot of technical knowledge to do it, just to have both devices within the same LAN, and we'll look at the standard tools, third-party tools from Xiaomi, and universal content streaming solutions.
Preparation of equipment and network
Before you start setting up, make sure your home network is ready to transmit heavy media content. The router must support Wi-Fi standards of at least 802.11n, although 5GHz is desirable for streaming video to 4K. The smartphone and TV must be connected to the network that your router distributes, not to the mobile Internet.
Note the software version. On LG TVs, you need to update your firmware to the current version via the Settings menu → All settings → Support → Software Update. On Xiaomi smartphones, it is also recommended to check for updates in the About Phone section, as newer versions of MIUI often contain patches for the Cast protocol.
⚠️ Note: If your router distributes the network at 2.4 GHz and 5 GHz with different names (SSID), Make sure your phone and TV are connected to the same frequency, sometimes isolating customers in router settings blocks the devices from seeing each other.
Check the activity of wireless modules. On the LG remote, press the Settings button and make sure that Wi-Fi is on. On the Xiaomi phone, swipe on top, open the notification curtain and activate geolocation — in some versions of Android, this is required to find nearby devices.
☑️ Checking before connection
Use of the built-in Screen Share feature on LG
LG TVs are equipped with a native Screen Share feature, which is based on Miracast technology, which allows you to broadcast a picture of the smartphone screen on TV in real time. To start working on the remote control, click the input button or select the Screen Share shortcut from the application launch menu.
When you start, you'll have a wait on your TV, and you'll have the TV go into visibility mode for external devices, don't close this window if you don't automatically connect right away, sometimes you need a manual search on the side of your smartphone.
On Xiaomi smartphones, the function can be called differently depending on the version of MIUI. Usually it is Broadcast or Wireless Monitor. You can find it in the notification curtain (the button can be hidden in the button editing menu) or in the settings: Connections and Sharing → Broadcast.
- 📱 Open the broadcast menu on Xiaomi.
- 📺 Launch the Screen Share app on your TV LG.
- 🔍 Wait for your name to appear. TV list of available devices.
- ✅ Click on the name of the TV to pair.
Once connected successfully, the image from the phone will appear on the big screen, and the latency can vary depending on the quality of the Wi-Fi signal. This method is ideal for viewing photos or videos, but for dynamic games, there can be lag.
Why isn't the TV on the list?
Broadcasting via LG TV Plus
The official LG TV Plus app (formerly LG Remote) provides enhanced functionality compared to standard Android tools, allowing you not only to control the TV as a remote, but also to transfer media files.
Once installed, launch the app and follow the instructions on the screen. The program will automatically scan the network and offer a list of available LG TVs. Select your model from the list. On the TV screen, a request for confirmation of pairing may appear - use the remote to agree.
In the application interface, go to Media or Gallery, where you can select photos or videos stored in your phone's memory and send them to playback, and the advantage of this method is that you can have stable connections and control playback (pause, rewind) right from your smartphone screen.
| Function | Screen Share (Miracast) | LG TV Plus | Google Home |
|---|---|---|---|
| Type of transmission | Screen cloning | Media files | Content casting |
| Dependence on the phone screen | Yeah (screen on) | No (Fon) | No (Fon) |
| Video quality | Depends on the signal. | Original | Original |
| Management | Phone from phone. | Phone from phone. | Phone from phone. |
Using an official app is especially important if you need to transfer a file without displaying the phone’s interface to the TV, which saves battery power on the smartphone, as the screen can go out during playback.
Broadcasting via Google Home and Chromecast
Many modern LG TVs support built-in Chromecast technology, which allows you to use the Google ecosystem to transfer content. To work this method on a Xiaomi smartphone, you need to install the Google Home app.
Launch the Google Home app and make sure you are logged in to your Google account. The program will find an LG TV on the network. Click on the device icon to open the control panel. The Cast screen button will be available at the bottom of the screen.
This method is convenient because it allows you to broadcast the contents of tabs in the Chrome browser or applications that support the Google Cast protocol (YouTube, Netflix, Twitch), unlike Miracast, where the load falls on the router and TV, and the phone acts only as a remote control.
⚠️ Note: When using Google Home, make sure you are on your TV LG In the network settings, external devices are allowed to access, and sometimes the antivirus on the router blocks the ports used by Google services.
If you have a Chromecast built in your model TV No, you can use a physical Chromecast console connected to HDMI The logic of the work will remain the same: the phone and the console communicate through the Google cloud or local network.
💡
To reduce latency when streaming games through Google Home, try prioritizing traffic in your router settings for the first time. MAC-The address of your TV (QoS function).
Xiaomi Mi Remote and ShareMe app
Xiaomi smartphones have a pre-installed Mi Remote app (Mi Remote) that, while primarily designed to control hardware via an infrared port, some versions of it can interact with smart appliances over Wi-Fi. Check if your LG model is on the list of supported devices within the app.
Another powerful tool from Xiaomi is the ShareMe app (formerly Mi Drop), which allows you to transfer files over Wi-Fi Direct. LG installed a browser with support for a web interface or an application for receiving files, you can send videos and photos directly, scanning QR-code.
To connect via ShareMe:
- 📂 Open the file (video/photo) on your phone.
- 📤 Click the "Share" button and select ShareMe.
- 📡 Select "Send" mode and find the device.
- 📺 Get a connection on the TV (if there is support).
However, the most reliable way for Xiaomi owners is to use the standard DLNA protocol through any file manager: In Xiaomi Explorer, select a file, click “Send” and select your LG TV from the list of available rendering devices.
💡
Xiaomi ecosystem applications (Mi Remote, ShareMe) work best with Xiaomi’s hardware, but LG prefers standard Android protocols or LG’s specialized software.
Troubleshooting and troubleshooting
Despite the ease of setting up, users often face problems, the most common being that the phone can't see the TV. 90% of the time, it's solved by checking the Wi-Fi frequency range. Make sure both devices are connected to a 2.4 GHz network or both to 5 GHz. Mixed modes sometimes block detection.
Another problem is intermittent image or audio/video desynchronization, which indicates low data rates or interference in the air, try to get closer to the router, disable downloads on other devices, or restart the router.
If there is an image but no sound, check the audio settings on the TV. Sometimes when you connect a new device, the audio output does not switch automatically. Go to Settings → Sound → Output and select the Wi-Fi Sound option or similar.
⚠️ Warning: If after all manipulations the connection is not established, reset the network settings on the TV. LG. It won’t delete your apps, but it will update them. IP-Address and network configurations, which often solve the problem of conflicts.
In rare cases, the problem lies in the firewall of the antivirus installed on the router or in the TV itself (if external protection is used).
