Modern Xiaomi smartphones and LG TVs have powerful multimedia functionality, allowing you to turn the gadget into a remote control of the home theater. Users often wonder how to stream from the shiomi to LG TV to bring photos, videos or gameplay to the big screen without unnecessary wires. This is possible thanks to built-in wireless data technologies such as Miracast and Wi-Fi Direct, which are supported by both manufacturers.
The setup process can vary depending on the version of the MIUI operating system and the year of the WebOS TV. In some cases, standard methods work instantly, in others they require the use of specialized intermediary applications. It is important to understand that the quality of the broadcast depends on the speed of your router and the distance between devices.
In this article, we’ll look at all the connectivity options available, from standard system tools to third-party utilities, how to avoid image delays, why your phone can’t see your TV, and what hidden settings you might need to keep things running smoothly. Follow the instructions to enjoy high-resolution content.
Device preparation and network verification
The first and most critical step is to ensure that the network infrastructure is right: In order for a Xiaomi smartphone and an LG TV to “see” each other, they must be on the same LAN, which means that both devices must be connected to the same Wi-Fi router.
If your router supports dual-band (2.4 GHz and 5 GHz), it is recommended to use 5 GHz for high-resolution video transmission, which will provide a wider bandwidth channel and reduce the likelihood of artifacts or stream interruptions. However, it is worth remembering that the 5 GHz signal range is smaller, so devices should be relativamente close to each other.
Check if the wireless module is on both gadgets. On an LG TV, this usually happens automatically when you connect to the network, but in rare cases, the Wi-Fi Direct or Screen Share feature needs to be activated manually in the network settings menu. On a smartphone, make sure that the Traffic Saving mode is not turned on, which can block local data transfer.
⚠️ Note: Using a mobile hotspot (wi-fi distribution from your phone) to connect your TV may not work for screen broadcasting, as some models may not work. LG They limit the functionality of Screen Share in such networks.
It's also worth updating the software of both devices to the latest available version. Manufacturers regularly release patches that improve compatibility between DLNA and Miracast protocols. Old firmware on the TV may be the reason the phone just doesn't detect the display in the list of available devices.
Use of the built-in Translation function in MIUI
The easiest and fastest way to install additional software is to use the system utility "Translation" (or "Cast"), built into the shell MIUI. This method is based on the Miracast standard, which allows you to duplicate the screen of the smartphone on the TV in real time.
To get started, lower the notification curtain on your Xiaomi and find the Translation icon. If it's not on the home screen of the Quick Settings menu, tap on a pencil or three dots to edit the panel and drag the desired widget to the active zone. Alternative path through the menu: go to Settings → Connection and Sharing → Broadcast.
Once the function is activated, the phone will start searching for available devices. The LG TV should start receiving the appropriate signal mode at this time. Depending on the model and version of WebOS, this may be called Screen Share, Smart Share or simply Connect to a Wireless Display.
- 📺 Press the Input or Settings button on the remote LG and select the Screen Share app».
- 📱 On the phone in the list of found devices, select your TV LG.
- 🔗 On the TV screen, a connection request may appear – confirm it by clicking “Accept” or “Allow».
- ✅ Image from the phone should be duplicated on the big screen.
It's important to note that when you use this method, your smartphone and TV screen sync completely, which means that any notifications, incoming calls or messages will be visible to everyone in the room, and if you're planning to watch a movie, you'd better turn on Do Not Disturb mode in advance.
Official LG TV Plus app for management
If standard screen broadcasting is unstable or you need to manage content rather than just duplicate the image, you should use the official LG TV Plus app, which is designed specifically to integrate mobile devices with the LG Smart TV ecosystem and offers advanced functionality.
Download the app from the Google Play store to your Xiaomi. Once installed, run the program and follow the instructions on the screen. The app will automatically scan the network and suggest a list of compatible TVs. Select your LG from the list.
One of the key features of the LG TV Plus is the ability to cast photos and videos from the phone gallery or streaming service directly onto the TV without loading the smartphone processor with full screen duplication, in which case the phone acts as a remote, and the TV plays content on its own using its decoder.
☑️ Checking before connection
In the interface, you'll find a virtual remote control that completely replaces the physical controller, which is especially useful if you've lost the remote or its buttons stuck, and there's also a file transfer feature available: you can quickly flip photos from the party to the big screen for general viewing.
Broadcasting via Google Home and Chromecast
Many modern LG TVs support Chromecast technology or have it as an external console. Even if there is no built-in Chromecast, Google Cast protocols are often integrated into the WebOS system.
Install the Google Home app from the Play Market and log in to your Google account. The program will detect all smart home devices on your network, including an LG TV. Click on the TV icon and you will see the “Cast my screen” button.
This method often works more consistently than Xiaomi’s native Miracast, especially when streaming videos from YouTube or Netflix. When you run a YouTube video on your phone and click the broadcast icon, the phone sends the TV just a link to the video stream, not the video itself, which saves battery and provides better picture quality.
| Method | Delay (Latency) | Quality. | Battery consumption |
|---|---|---|---|
| Miracast (Translation) | Low (for games) | Depends on the signal. | High-pitched |
| LG TV Plus | Medium | Original | Medium. |
| Google Cast | Minimum | Maximum. | Low. |
| HDMI Cable | Absent. | No compression. | Charging. |
If your LG TV is older and doesn’t support Google Cast natively, you can purchase an external dongle Chromecast that connects to the HDMI port.This will instantly update the functionality of the old TV, making it compatible with all modern transmission standards from Xiaomi.
Third-party applications for complex cases
There are situations when regular funds do not work due to software conflicts or features of the Android version. In such cases, third-party aggregator applications such as WebVideo Caster, LocalCast or BubbleUPnP come to the rescue. These programs are able to find a common language with almost any DLNA-compatible device.
The way they work is similar: you install an app on Xiaomi and, if necessary, a companion app on an LG TV (via the LG Content Store), and after pairing, you can stream video files stored in your phone’s memory or stream video from your browser.
Why are third-party apps sometimes better?
Special attention should be paid to the settings of the firewall. Sometimes antivirus or system restrictions MIUI block the work of third-party programs. Go to Settings → Applications → All applications, find the caster used, and in the section "Saving charge" select the option "No restrictions", which will prevent forced stop of the process by the background service.
Wired connection through HDMI-adapter
For users who are critically important to connect and avoid any delays (for example, to show presentations or games), the best solution is wired connection. Since the USB-C connector on Xiaomi smartphones does not always support video output (MHL technology or DisplayPort Alt Mode), you need to use an active adapter.
You will need a USB-C to HDMI adapter. Connect one end to the phone and the other to the HDMI cable that goes to the LG TV. Switch the signal source to the TV to the corresponding HDMI 1 or HDMI 2 port.
The advantage of this method is that it does not depend on the speed of Wi-Fi and does not put a strain on the wireless network.In addition, while the broadcast is ongoing, the phone can charge (if the adapter has a charging port), which allows you to watch long movies without fear of draining the battery.
⚠️ Note: Not all Xiaomi models support video output via USB-C. Flagship series (Mi, Xiaomi Number series) are usually supported, while budget models (Redmi) are generally supported, POCO entry level) may not transmit video signal through the charging port.
Problem Solving and Frequently Asked Questions
Despite its apparent simplicity, users often face difficulties: the TV is not visible in the list, the image twitches or the sound is missing, most often the problem lies in the router settings, where AP Isolation (AP Isolation) client isolation can be enabled, preventing devices from seeing each other on the local network.
Also worth checking permissions. When you first start the broadcast function, Android asks for permission to access the local network and microphone (to transmit sound). If you accidentally refuse access, the function will not work. You can reset permissions in the settings menu of a particular application.
💡
If the broadcast is slowing down, try lowering the screen resolution in your phone’s settings or closing background apps that consume internet traffic, such as torrents or downloads on Steam.
In rare cases, a complete reset of network settings on your phone helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.This will remove stored Wi-Fi passwords, but often solves problems with device detection protocols.
💡
The broadcast stability is 90% dependent on the quality of the Wi-Fi signal and the lack of software-based ad blockers at the router or DNS level.
