With modern technology, it’s easy to turn your smartphone into a powerful multimedia center by streaming content to a big TV screen. Connecting a Xiaomi phone to an LG TV wirelessly opens up access to photos, videos and games on a high-diagonal panel, especially when embedded Smart TV apps don’t support the right file format or the interface seems inconvenient.
Owners of the MIUI ecosystem often face the need to output images for presentations or watch movies from cloud storage. Fortunately, LG has implemented Miracast and DLNA standards in its panels, making synchronization as simple as possible, and you don’t need additional cables or complex adapters if both devices are on the same network.
In this article, we will take a look at all the available connection methods, from standard Android features to specialized applications. We will also touch on the technical nuances that can arise when configuring, and offer solutions for stable operation.
Technical requirements and equipment preparation
Before you start setting up, you need to make sure that your equipment meets the minimum requirements for wireless data transfer. The main condition is that you have a WiFi module in both devices and connect them to the same access point. It is desirable that the router maintains a frequency of 5 GHz, as this will provide a more stable data stream when broadcasting video in 4K.
LG TVs must support Screen Share technology or have a built-in webOS platform (starting with version 3.0). Xiaomi smartphones are equipped with Translation or Wireless Monitor function in almost all current models. If your router distributes network at 2.4 GHz and 5 GHz simultaneously under the same name, there should be no problems, but sometimes splitting networks helps solve problems with the visibility of devices.
⚠️ Warning: Make sure your TV is turned off Guest Network, as it often blocks interaction between devices within the LAN, even if they are connected to the same router.
It’s also worth checking the software’s relevance, which can be done through the system settings menu on LG TVs, and on Xiaomi phones, it can be done under the About Phone section, which often includes security protocol fixes and improves compatibility with various broadcast standards.
Use of the built-in Translation function in MIUI
The fastest way to mirror the screen is to use the native feature of the Android operating system with the MIUI shell. This method does not require the installation of third-party software and works at the system level. The algorithm of actions is extremely simple, but requires carefulness when choosing a device from the list of available devices.
To start, unlock your smartphone and lower the notification curtain down. Find an icon called Translation, Wireless Monitor, or Cast. If it's not available, tap a pencil or three edit points to the panel and add this element. Once activated, the phone will start looking for available displays within range of the network.
On LG TV, you need to run the Screen Share app (on older models) or just make sure that the external device search function is active in the All settings menu → Connect → Screen Share. On new models with webOS, just click the signal source select button and select Connect to a mobile device.
☑️ Checking before connection
When your TV name appears on the list on your smartphone screen, just tap it. The connection process takes a few seconds, after which the image from the phone appears on the big screen.
💡
To reduce latency during games, close all background apps on your smartphone that actively use the Internet, such as torrents or cloud syncs.
Multimedia streaming via LG TV Plus app
If you don't need to mirror the entire screen, but you just need to show a photo or run a video file, it's more convenient to use a specialized application. The official LG TV Plus program (or its modern LG ThinQ version) allows you to control the TV and stream content from the phone's gallery, a solution that often works more stable than the system broadcast, especially for heavy files.
Download the app from the Google Play store and run it. The program will automatically scan the network and find your LG TV. After pairing (you need to confirm the code on the TV screen), you will access the control panel and media library. Select the desired file in the Photo and Video or Music section, and it will open on the TV.
The advantage of this method is that you can use the phone for other tasks while the video is played on the TV, and the app supports playback control: pause, rewind and volume are adjusted directly from the smartphone interface, which is ideal for watching family albums or presentations.
| Parameter | System Translation (Miracast) | LG ThinQ Application | Chrome Cast |
|---|---|---|---|
| Type of transmission | Screen mirroring | Translation of files | Broadcasting tabs |
| Delay. | Low (for games) | Absent. | Medium |
| Battery consumption | High-pitched | Medium. | High-pitched |
| Background mode | Impossible. | Possible. | Depends on the app. |
It’s worth noting that app functionality can vary depending on the year the TV is released. Models up to 2018 may require LG TV Plus, while new devices work better with the ThinQ ecosystem. Either way, both methods allow you to effectively use the bundle of Xiaomi and LG for content consumption.
Broadcasting through the Google Chrome browser
The universal solution, which works on almost any device with Google Chrome installed, is the Translate feature, which is especially useful if standard MIUI tools for some reason do not see the TV or work correctly, and allows you to display not only the browser tabs, but the entire desktop of the smartphone.
Open the Chrome browser on your Xiaomi. Click on the three dots in the top right corner of the menu and select "Translate" (Cast). In the window that opens, you will see a list of available devices. Before you start the broadcast, click on the "Translate screen" (or "Translate tab") button to select the signal source.
Chrome Menu → Three Dots → Broadcast → Select a DeviceOnce you select your LG TV, you'll start transferring images, which is good because it's cross-platform and doesn't depend on the firmware version of the phone, but you need a stable WiFi connection to work comfortably, because the browser creates an additional layer of software processing for the video stream.
Why can’t the Chrome streaming work?
Solving Common Connection Problems
Despite the simplicity of the technology, users may encounter difficulties pairing devices. One of the most common problems is that the TV does not appear in the list of available devices on a Xiaomi smartphone. In this case, the first thing to check is whether the router is activated customer isolation (AP Isolation), a security feature that prevents devices inside the network from “seeing” each other.
Another reason could be a crowded WiFi channel. If there are many neighbourhood networks around, the signal can be unstable. Try rebooting the router and reconnecting both devices. Also, switching between 2.4 GHz and 5 GHz frequencies helps if your router supports dual broadcasting.
⚠️ Attention: If you connect an image to twitch or interrupt sound, try to reduce the output resolution in the broadcast settings or get closer to the router.
In some cases, resetting network settings on your phone helps. Go to Settings → Connection and Sharing → Reset WiFi, mobile networks and Bluetooth. This action will remove saved passwords, but often resolves software conflicts of wireless drivers.
💡
90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
Alternative applications for advanced users
If the standard tools don’t meet your needs, Google Play offers a variety of third-party solutions, apps like AllConnect, BubbleUPnP or LocalCast provide advanced options for managing codecs and file formats, and are especially useful if the LG TV doesn’t “understand” the format of the video you’re trying to run.
For example, BubbleUPnP allows you to stream content not only from your phone, but also from network storage (NAS) or cloud services directly to your TV, using your smartphone as a remote, which reduces the load on the phone’s processor, as it acts only as a controller, not a stream source.
When choosing third-party software, pay attention to the availability of advertising and the permissions required. Some free versions may limit stream quality or session duration. For regular use, it is better to consider paid versions or open source applications that guarantee no hidden miners.
