Modern smart home ecosystems make it easy to combine devices from different manufacturers, turning a smartphone into a powerful remote control and multimedia center. Xiaomi owners often wonder how to effectively use the large screen of LG TV to view photos, videos or games. Fortunately, wireless data standards such as Miracast and DLNA are built into the MIUI shell and the webOS operating system, making the pairing process as simple as possible and does not require complex equipment.
There are several proven methods, each of which has its own advantages depending on your goals: whether you just need to show a presentation to colleagues, run a movie from an online cinema, or completely clone the smartphone interface to a large panel. Wireless connection is a priority today, because it eliminates unnecessary wires and allows you to move freely around the room.
In this article, we will take a look at all the current broadcasting methods, from built-in system functions to specialized applications. You will learn how to activate projector mode, use Apple AirPlay technologies on Android smartphones and what nuances the transmission of sound and image in high resolution. Proper setting of the router and knowledge of the features of your LG TV model will help to avoid delays and dissynchronization of audio.
Use of the built-in Translation function in MIUI
The fastest and most native way to display an image from a Xiaomi smartphone to an LG TV screen is to use the system function “Translation” (Cast), which is based on the Miracast protocol, which is supported by most modern Smart TVs. To start, you do not need to install additional software, just activate the corresponding module in the notification curtain or system settings.
Before starting the procedure, make sure your LG TV is on and connected to the same Wi-Fi network as your smartphone. On the remote, click on the "Input" or "Smart" button, then search for the "Screen Share" or "Connect to Mobile Device" app. Once this app is launched, the TV will go into standby mode and the name of the device ready to pair will appear on the screen.
On a Xiaomi smartphone, lower the top notification curtain and find the Translation icon. If it's not visible, click on the edit button (usually three dots or a pencil) and drag the icon to the active panel. Once activated, the system will start looking for available devices. When your LG TV appears on the list, tap its name.
☑️ Checking before connection
Once successfully connected, the image from the phone will instantly appear on the big screen, in which the screens are synchronized, meaning that all your actions, notifications and turns of the smartphone will be duplicated on the TV, ideal for showing a photo gallery, navigating maps or showing documents.
⚠️ Note: When using the built-in broadcast via Miracast, the smartphone can heat up more, and the battery will be consumed faster due to the active operation of the Wi-Fi module and the graphics processor.
DLNA Technology and Multimedia Transmission
If your goal is not to duplicate the screen, but to play back video files, photos or music stored in the phone’s memory, then DLNA will be a more efficient solution. Unlike Miracast, it doesn’t create an exact copy of the screen, but only transmits media content, allowing the TV to decode the file itself, which reduces the load on the smartphone battery and often provides better picture quality.
To implement this method, LG must run a Photo and Video app or similar media player that supports access to external devices. On the Xiaomi side, you can use the standard gallery or video player "Mi Video." Open the desired file, click the "Translate" button (the rectangle icon with Wi-Fi waves) and select your TV from the list of available renderers.
The advantage of DLNA is that you can control playback directly from your phone without interrupting the process. You can pause the video, rewind or adjust the volume while the TV is streaming, and it also allows you to play video in the background using your smartphone for other tasks.
| Characteristics | Miracast (Translation) | DLNA (Media) |
|---|---|---|
| Type of transmission | Full screen cloning | Media files only |
| Impact on the battery | High. | Medium/Low |
| Background mode | Impossible (screen active) | Possible. |
| Video quality | Depends on the Wi-Fi signal. | Original File Quality |

LG TV Plus app for advanced management
The official LG TV Plus app (formerly known as LG TV Remote) opens up additional possibilities for integrating Xiaomi’s smartphone and LG TV. While its primary function is to manage the channel and settings, it also supports the Screen Share feature, which often works more stable than the standard MIUI system solution.
Download the app from the Google Play Store and launch it. The program will automatically find the TV on the local network. After pairing (the confirmation code may appear on the TV screen), go to the media or screen management section. The application interface is adapted to work with content, allowing you to conveniently sort photos and videos before sending to the big screen.
One of the key features of using proprietary software is the ability to transfer files of certain formats that a standard phone player may not see as supported by a TV.
- 📱 Convenient control of the mouse cursor on the TV screen through the touchscreen of the smartphone.
- 🎬 Support for playlists for music and photos with interval settings.
- 🔒 The ability to block children’s access to certain TV functions via a smartphone.
- ⚙️ Access to advanced image and sound settings without looking for a remote.
It is worth noting that the application requires permission to access the local network and files for the correct operation of the application. If the LG TV Plus does not see the TV when it starts, check the firewall settings in the router or try to restart both devices.
Broadcasting via Google Home and Chromecast
Many modern LG TVs are equipped with built-in Chromecast support or are compatible with this technology through the Google TV platform.This is one of the most reliable ways to stream content from apps such as YouTube, Netflix, Google Photos or the Chrome browser.The Cast protocol from Google provides minimal latency and high quality streaming.
To get started, make sure your Xiaomi has Google Home installed. Open it and find your TV in the device list. If you want to stream the contents of your browser tab or the entire screen, click on the device name and select the option “Translate screen.”
You should pay special attention to live streams from your Chrome browser. Open the desired web page with a video, click on three dots on the menu and select Translate. You can choose to stream a particular tab or the entire desktop. This is a great way to watch videos from sites that do not have a separate Smart TV app.
What if Chromecast doesn’t see the device?
The advantage of the Google Home method is that it's versatile, and virtually any Cast-enabled app will work smoothly, and the smartphone will only act as a remote, so you can use it for calls or games without interrupting playback on your TV.
Using AirPlay 2 on LG TVs
While Xiaomi runs on Android, many of LG’s current TV models (starting in 2019) support Apple’s AirPlay 2 technology.This means you can take advantage of Apple’s ecosystem even with an Android smartphone, as long as the manufacturer has added appropriate support to the shell, or through third-party emulator apps.
Some Xiaomi models with the updated MIUI shell have AirPlay support built into the stream menu. If your phone does not see the TV as the default AirPlay device, you can use third-party receiver apps installed on the TV itself through the LG Content Store, such as AirScreen or AirReceiver.
Once installed on an LG TV, it emulates the AirPlay receiver. On a Xiaomi smartphone, you can choose this virtual receiver from the Translation menu or supported video players.This is especially useful if the standard Miracast runs non-stable--WIDGET:poll:What broadcast method do you use more often?:Integrated Translation (Miracast)|Google Home|LG TV Plus| Third-party apps (AirScreen) |Wired connection-->
Wired connection via HDMI and USB-C
For situations where the wireless network is overloaded or requires maximum image quality without compression, it is worth considering a wired connection. Most modern Xiaomi smartphones are equipped with a USB Type-C port that supports video output (DisplayPort Alt Mode).
To connect, you'll need a USB-C to HDMI adapter. One end connects to your smartphone, the other to the free HDMI port on your LG TV. Once connected, the TV automatically detects a new signal source. You only have to select the appropriate input (Input) on the TV remote.
This method ensures no lag, which is critical for mobile games or presentations, and when wired, the smartphone can charge simultaneously if the adapter has an additional power port (PD charging).
- 🔌 No dependence on Wi-Fi speed and interference in the air.
- 🎮 Ideal for gaming due to zero input delay.
- 🔋 Possibility to charge the smartphone during use.
- 📉 Stable high bitrate sound transmission (Dolby Digital, DTS).
⚠️ Note: When using cheap adapters without external power, the smartphone can quickly discharge or not give a signal 4K. It is recommended to use certified cables with support HDMI 2.0 and higher.
Troubleshooting and troubleshooting
Despite the ease of setting, users may encounter problems: the TV can’t see the phone, the image twitches or there is no sound. The first step should always be to check the network. Make sure that both devices are connected to the main network, not the guest network (Guest), and that they use the same frequency range (preferably 5 GHz for video transmission).
If the connection is cut, try restarting the router. Often the problem is overflowing the router buffer or conflict. IP-Also worth checking for firmware updates for the TV. LG via the Settings menu → All settings → General. → On TV. → Verification of updates.
If you have a problem with your audio when broadcasting your screen, check your Bluetooth settings. Sometimes your smartphone tries to send the sound to your connected headphones or speakers while ignoring your TV, disable your extra Bluetooth devices, or force your TV to be the output device in the control panel.
💡
90% of connection problems are solved by restarting the router and checking that the phone and TV are on the same subnet (the same is true). IP-lock-house).
If neither method works, reset the network settings on Xiaomi’s smartphone.This will remove stored Wi-Fi passwords, but often eliminates protocol stack software errors that prevent devices from being correctly detected on the local network.
