Xiaomi’s modern smartphones have powerful multimedia capabilities that allow you to display images on the big screen. Owners of LG TVs with support for Smart TVs often look for ways to broadcast content without unnecessary wires. This can be watching photos, videos from the gallery or even running games on the full screen.
There are several proven methods, each with its own advantages: the choice of the specific method depends on the model of your TV, the version of the MIUI operating system or HyperOS, as well as the availability of a stable Wi-Fi connection. In some cases, it is preferable to use a wired connection for maximum stability and minimal signal delay.
Preparing devices for synchronization
Before setting up, make sure both devices are ready to go. Xiaomi smartphone and LG TV should be on and active. It is critical that both gadgets are connected to the same Wi-Fi network. If the router supports dual-band, it is better to use 5 GHz frequency for faster data transfer.
Check for software updates on both devices. On your TV, you can do this through the Settings menu → All settings → Support → Software Update. On your smartphone, the path usually looks like Settings → About Phone → MIUI version. Outdated firmware versions may contain bugs that prevent devices from being found on the local network.
⚠️ Note: If your router has a Guest Network feature, don’t connect your broadcast devices to it.This feature isolates your devices from each other, and your smartphone simply won’t “see” the TV.
Make sure your TV has a Smart Share or similar detection service activated. In newer LG models with webOS, this option is often enabled by default, but older versions may require manual activation in the network settings section.
Broadcasting through the built-in function "Translation"
The fastest way to bring a smartphone screen to a TV is to use the Miracast system function, which is called Translation in the MIUI shell, which allows you to completely duplicate the image from your smartphone to the big screen in real time, without installing additional applications and supports audio transmission.
To start the function, lower the notification curtain and find the Translation icon. If it is not available quickly, go to Settings → Connection and Sharing → Broadcast. Once turned on, search for available devices will begin. Your LG TV should appear on the list.
💡
If the search takes too long, try rebooting the Wi-Fi module on your smartphone by turning on and off Air Mode for a couple of seconds.
Once you select your TV, you may see a request to confirm your connection. Use the LG remote to click "Confirm" or "Accept." The image quality will depend on the Wi-Fi signal strength and the distance between the router and the devices.
⚠️ Note: When using the function "Translation" screen of the smartphone does not go out, which can lead to accelerated battery discharge and heating of the case.
💡
Miracast is ideal for presentations or photos, but is not suitable for games due to possible input delay (input lag).
Use of the LG ThinQ application
LG’s official ThinQ app provides enhanced control over the TV and allows you to stream multimedia content, a solution that is especially useful if standard screen broadcasting is unstable or requires the management of media files, rather than the entire interface of the smartphone.
Download the LG ThinQ app from the Google Play store and install it on your Xiaomi. Once launched, the app will automatically scan the network and prompt you to add your TV. Follow the on-screen instructions by entering the confirmation code that will appear on the TV display.
- 📱 Open the app and select your TV from the list of available devices.
- 📂 Click on the Media or Gallery icon inside the app to select files.
- ▶️ Select a video or photo and it will open on the TV screen while the smartphone can be used for other tasks.
The advantage of this method is that you can control playback from your phone while the TV is busy displaying content, so you can pause the video, rewind or change the volume without interrupting the process.
Connect with Google Home (Chromecast built-in)
Many modern LG TVs have a built-in Chromecast feature that allows you to stream content from applications that support this protocol, such as YouTube, Netflix or the Chrome browser, which provides high picture quality and a stable connection.
Make sure that the Xiaomi smartphone has the Google Home app installed and updated. Open it and find your TV in the device list. Click on the TV name, then select the option to Translate the screen, or use the broadcast button inside a particular app (like the YouTube Wave rectangle icon).
This is different from Miracast in that the TV itself downloads content from the Internet, and the smartphone acts only as a remote control, which reduces the load on the Wi-Fi network and saves battery power.
| Characteristics | Miracast (Translation) | Chromecast (Google Home) |
|---|---|---|
| Type of transmission | Screen duplication | Streaming link |
| Dependence on the phone | High (screen active) | Low (you can fold the application) |
| Battery consumption | High-pitched | Low. |
| Delay (Latency) | Medium/High | Minimum |
Why can't Chromecast work?
Wired connection through HDMI-cable
For maximum image quality and no delays, a wired connection is best. However, Xiaomi smartphones don’t always have a standard HDMI connector. You’ll need a dedicated USB-C to HDMI adapter.
It is important to consider that not all Xiaomi models support video output via a USB-C port. The MHL or DisplayPort Alt Mode feature is available mainly in flagship series (for example, Mi 10/11/12/13 Pro, Xiaomi 13/14). Budget models of the Redmi or Poco series often do not have this capability.
☑️ Checking before buying the cable
Connect the adapter to your smartphone and the HDMI cable to your TV. Switch the TV signal source to the appropriate mode (e.g. HDMI 1). The image should appear automatically. If this does not happen, check the resolution settings in Settings → Screen → External Display.
⚠️ Note: When using cheap adapters without additional power, the image may blink or disappear.
Broadcasting through DLNA-player
If the built-in methods do not work or you need to play a file of a specific format, third-party will come to the rescue. DLNA-Players. Popular apps like VLC For Android or BubbleUPnP lets you find renderers (TVs) on the network and send video files to them.
Install the player you select on your Xiaomi smartphone. Open the video file through the app, click on the broadcast icon (usually in the corner of the screen), and select your LG TV from the list. The TV will receive a stream of data and play it on its own.
This is a good technique because the player can transcode video on the fly if the TV doesn't support the file format, but heavy 4K files may require very fast Wi-Fi, otherwise slowdowns are possible.
💡
DLNA-Players are the best solution for viewing local heavy format video files that a native TV player does not read.
Solving Connection Problems
Despite the ease of setting up, users often face difficulties, and the most common problem is that devices can't see each other, so check if the router is using AP Isolation, and try temporarily disabling antivirus or firewalls on your smartphone if they block local connections.
If the broadcast is with delays or jerks, try to reduce the quality of the output image in the broadcast settings or bring the smartphone closer to the router. Sometimes it helps to change the Wi-Fi channel of the router to a less busy one, especially in apartment buildings.
In rare cases, you need to reset your network settings on your TV. → Network → Wi-Fi, select your network and click "Forget," then reconnect by entering your password. IP-address and network routes.
