Today’s users are rarely content with a small smartphone screen when it comes to watching videos or photo albums. How to connect Xiaomi to an LG Smart TV is becoming especially relevant for Android ecosystem owners who want to enjoy content on a large display. Fortunately, Miracast technology and built-in MIUI or HyperOS shell features allow you to do this without unnecessary wires and complex settings.
The process of synchronizing devices is based on the use of Wi-Fi Direct wireless protocol, which provides direct transmission of high-definition video stream. HDMI-cables if both gadgets are on the same network, but there are nuances associated with firmware versions and TV models that must be considered for stable operation.
In this article, we will take a look at all the available methods, from the standard system tools to third-party applications that may be needed in difficult cases. We will also discuss the topic of eliminating the typical errors when the phone sees the router but does not detect the TV. Get ready to turn your LG Smart TV into a full-fledged multimedia center, managed from a familiar smartphone.
Basic requirements and equipment preparation
Before you start the active setup phase, you need to make sure that your equipment meets the minimum technical requirements.The foundation for successful wireless broadcasting is the presence of a Wi-Fi module in both devices.It is critical that Xiaomi smartphone and LG TV are connected to the same wireless network.If you have a dual-band router, make sure that both devices sit on the same frequency (usually 2.4 GHz or 5 GHz), although modern routers often combine them into the same network.
The second important aspect is the relevance of the software. LG TVs use the webOS operating system, which has built-in support for Miracast technology (often labeled as Screen Share). On Xiaomi smartphones, this feature can be called differently depending on the version of the shell: "Translation", "Wireless Monitor" or "Cast." Make sure that both devices are enabled Bluetooth, as it is often used for initial handshakes and search devices in range.
⚠️ Note: If your router is configured with client device isolation (AP Isolation, phone and TV won't see each other even when they're on the same network, a security feature often turned on in guest networks or offices.
It’s also worth checking your smartphone battery. The process of transmitting a video stream in high resolution 1080p or 4K consumes significant energy. It’s recommended to keep the device charged or connect it to a power source if you plan a long browsing session. Ignoring this advice can lead to a sudden shutdown of the phone at the most inopportune moment.
Method 1: Broadcasting through the built-in MIUI/HyperOS function
The easiest and fastest method that doesn't require any additional software is to use the Translation system utility. This method implements the Miracast protocol at the system kernel level, which ensures minimal image latency. First, unlock your Xiaomi smartphone and lower the notification curtain. In the Quick Action menu, find an icon called Translation, Wireless Monitor, or a wave rectangle icon. If there is no icon, click on a pencil or three dots to edit the list, and add a widget.
Once activated, the phone will start searching for available devices. At this point, you need to prepare the TV. Take the LG Magic Remote remote and press the "Input" button or search the Screen Share app in the main menu. Run it and the TV will go to standby mode. The list of available devices on the smartphone screen should be updated, and you will see the name of your TV (for example, LG webOS TV).
Tap the name of the TV on the list. You can see a request for permission to connect on the TV screen — confirm it using the remote. After that, the image from the Xiaomi smartphone is completely duplicated on the big screen. You can switch between applications, flip through social media feeds or show presentations, and everything will be visible on the TV. The quality of the picture automatically adapts to the bandwidth of your Wi-Fi network.

Method 2: Use the LG TV Plus app
If standard screen broadcasting is unstable or you need advanced control functionality, the official LG TV Plus app is a great solution. It is available for download from the Google Play Market store on Xiaomi devices. This method is good because it allows you not only to broadcast media files, but also to use your smartphone as an advanced remote with a touchpad and keyboard, which is especially convenient for typing text when searching for videos.
Once you install the app, run it and follow the instructions on the screen. It automatically scans the network and finds your LG TV. To complete the pairing, the TV screen will have a code that you need to enter in the app on your smartphone. Unlike Miracast, you don't duplicate the entire screen, but you choose specific content to display. This allows you to use the phone for other tasks while the TV is playing video.
In the application interface, go to Media or Gallery, select the photos or video files stored in Xiaomi memory. Click on the broadcast icon and the content will play on the TV. The app supports most popular formats, including MP4, JPG, AVI and MKV. In addition, you can control volume through LG TV Plus, switch channels (if you have an antenna or IPTV connected) and run the built-in TV applications.
Why can't the app see TV?
Method 3: Streaming through Google Home and Chromecast
Many modern LG TVs support Google Cast (Chromecast built-in) technology, which allows you to stream content directly from apps like YouTube, Netflix or Google Chrome without straining your smartphone’s processor. To work this method, the Xiaomi phone must have a Google Home app installed, which is often already built into the system, but may require an update.
Run Google Home and make sure you're logged in to your Google account. The app will show you the available Cast devices on your network. Select your LG TV from the list. You can use the Translate Screen feature to duplicate the entire interface or stream content from specific apps that support this feature. The advantage of the method is high-quality picture and the ability to control playback from the phone.
If you don't have Chromecast built-in support for your TV, you can use Google Chrome on your smartphone. Open the right page or video, click on the menu (three dots) and select Translate. The system will suggest you choose a device. This is universal and works on almost any LG Cast-protocol-enabled models, providing a stable connection even with a weak Wi-Fi signal.
💡
To reduce latency when playing mobile games on your TV via Cast, close all background apps on Xiaomi and turn off downloads on the network.This will free up the Wi-Fi channel for video streaming.
Connection problems and their solution
Despite its apparent simplicity, users often encounter a situation where Xiaomi does not see an LG TV. One of the most common reasons is the use of different Wi-Fi frequencies. If the router distributes 2.4 GHz and 5 GHz networks with different names (SSID), make sure that both devices are connected to one of them. Different subnets can create a virtual wall through which devices cannot "hello".
Another common problem is Xiaomi’s power saving settings. Aggressive battery optimization can kill device search in the background. Go to Settings → Battery and performance and make sure that system services or broadcast apps are not subject to strict restrictions. It’s also worth checking whether Flight mode is on or if the Wi-Fi module on one of the devices is banal due to a failure.
The table below shows the main symptoms and ways to eliminate them:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Phone can't see TV | Different Wi-Fi networks | Reconnect both devices to the same router |
| Image twitches | Weak Wi-Fi signal | Getting closer to the router or reducing the quality of the video |
| No TV sound. | Wrong conclusion is chosen | In the broadcast app, select the sound output on TV |
| Black screen | Codec incompatibility | Use a different player or convert video |
Sometimes it helps to simply restart network settings. On Xiaomi, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. On an LG TV, you can quickly restart by holding the switch off button on the remote for 5 seconds. This will clear the cache of network services and often solve the problem of “invisibility”.
Use of third-party broadcasting applications
When the regular funds fail, third-party development comes to the rescue, and one of the most popular and functional solutions is the TV Cast for LG TV or Web Video Caster app, which can pull video streams from browsers and players, transcode them on the fly into a format that the TV can understand, and send them over the web, which is especially useful for watching videos from sites that do not have official Cast support.
Install the app you select from Google Play. You use the same principle for most of these utilities: you open the built-in browser inside the app, go to the site with a video (for example, an online cinema) and run a video. In the corner of the screen, a connection button will appear to the device. Select your LG TV. The application will create a local server and transmit a link to the video stream to the TV, which will download and play the content itself.
⚠️ Note: Third-party apps may collect data about your browsing or display ads. Use only proven high-ranking programs and carefully read permissions when installing.
The advantage of these apps is that they support a wide range of formats and subtitles. If you're watching a movie from an external resource and you need subtitles, the TV Cast app often lets you download them separately or find them automatically, and they usually have a built-in file manager that allows you to stream videos stored deep in the Xiaomi file system, where standard tools may not get.
💡
Third-party applications are “heavy artillery” that saves when standard Miracast or DLNA protocols fail or fail to support the desired file format.
Broadcasting through HDMI-cable)
For those who require maximum picture quality without compression and delays, or if the Wi-Fi network is overloaded, there remains a proven wired method. To connect Xiaomi to the LG TV, you will need a USB-C to HDMI adapter. Importantly, your smartphone should support video output technology via a USB port (MHL or DisplayPort Alt Mode).
Connect the adapter to the charger of the phone, and connect to the adapter conventional HDMI-Put the second end of the cable in the free port. HDMI TV-wise LG. Switch the signal source to the TV in the appropriate mode (for example, HDMI The image should appear instantly. Unlike wireless methods, it does not matter whether the Internet speed or interference in the air.
This method is ideal for gaming, as there is almost no input lag. However, there is a caveat: the phone screen can be locked or used as a touchpad, depending on the settings of HDMI mode. Some Xiaomi models automatically switch to desktop mode when connecting the cable, like a computer, which allows you to conveniently manage windows on the large screen.
