Modern Xiaomi smartphones have powerful screens and processors, but 6-inch diagonal is often not enough to watch family movies or vacation photos. Happy owners of LG smart TVs can easily solve this problem by connecting the gadget to a large display over a wireless network or cable. This allows you to enjoy content in high resolution using the convenience of a mobile operating system.
There are several proven methods of synchronizing devices, each with its own advantages depending on your goals: you can use the built-in Mi Drop feature, the standard Miracast protocol, or physical connection via HDMI. The choice of the specific method depends on your TV model, the version of the MIUI firmware, and the availability of a stable Wi-Fi connection.
In this article, we will take a detailed look at all the current connectivity options so that you can choose the most suitable for your situation, and we will look at both standard system settings and third-party solutions that can be useful in difficult cases.
Use of the built-in wireless display function
The simplest and most common way is to use Miracast technology, which is built into the MIUI shell called Translation, which requires no additional applications and works on most modern LG TVs with Smart TV function.
To get started, unlock your smartphone and lower the notification curtain down. Find an icon called Translation or Cast. If you can't see it on the control panel's home screen, click on the edit icon (usually a pencil or three dots) and drag the button to the visible area. Once activated, the phone will start searching for available devices.
On an LG TV, you need to make sure that the signal reception function is active, and depending on the year of the model, this option can be called differently, often just turn on the TV and be in the Smart TV menu, since many LG models automatically go into standby mode.
⚠️ Note: When using a wireless connection, the room should not have too many active Wi-Fi networks of neighbors, as this can cause interference and dissynchronization of the image with sound.
When the search is complete, a list of available devices will appear on your smartphone screen. Select your LG TV from the list. A request for confirmation of connection may appear on the TV screen — it must be received using the remote control. After that, the phone screen will be fully copied to the large display.
Connection via HDMI cable and adapters
If the wireless connection is unstable or you need to transfer the image in the maximum quality without delay, the best choice will be a wired connection. For this you will need a special USB-C to HDMI adapter, since direct connection of the USB cable to the HDMI is impossible without a signal converter.
Connect the adapter to your Xiaomi charging connector and then insert HDMI-cable to the adapter and to the free port of the TV LG. Switch the signal source on the TV to the appropriate input (e.g, HDMI 1 HDMI Image must be automatically produced by technology MHL DisplayPort Alt Mode.
It is important to consider that not all Xiaomi smartphone models support video output via a USB port. Budget models often lack this feature, so it is recommended to check the specification of your device on the manufacturer’s official website before buying an adapter.
- 🔌 Adapter should support video transmission, cheap charging cables will not work.
- 📺 Make sure the TV is on the TV. LG Supports the permission that the phone gives out.
- 🔋 When wired, the phone can discharge faster if the adapter does not have additional power.
☑️ Checking before buying an adapter
Broadcasting via LG TV Plus
The official LG TV Plus app (or its newer versions, such as LG ThinQ) provides advanced control and broadcasting capabilities, allowing not only duplicate screens, but also transfer media from the phone gallery directly to the TV using the DLNA protocol.
Download the app from Google Play and install it on your smartphone. Run the program and follow the instructions on the screen to find your TV. Both devices must be connected to the same Wi-Fi network. Once paired, you will have access to TV management and Screen Share.
The advantage of this method is that you can control your TV directly from your smartphone screen, you can change channels, adjust volume, and start content without getting out of the couch, which is especially useful if your LG TV remote is lost or out of order.
What to do if the app can’t see the TV?
Using Chromecast built-in technology
Many modern LG TVs run on the webOS platform, which has built-in support for Google Chromecast.This allows you to stream content from apps like YouTube, Netflix or Google Chrome with the touch of a button.
Unlike a full screen broadcast (Screen Mirroring), here you only send a video stream, which means you can continue to use your phone, text or play games while the TV is in the movie, and the image quality is often higher, because the TV itself downloads the stream from the Internet.
Open the supported app on Xiaomi's phone and find the broadcast icon (a rectangle with waves in the corner). Click on it and select your LG TV. The connection will be set up instantly and the video will start playing on the big screen.
| Parameter | Miracast (Translation) | Chromecast | HDMI Cable |
|---|---|---|---|
| Delay. | Medium/High | Minimum | Absent. |
| Quality. | Depends on Wi-Fi. | High (up to 4K) | Maximum. |
| Battery consumption | High-pitched | Low. | Charging is possible. |
| Convenience | High. | Very high. | It requires wires. |
Configure permission and frequency of update
When displaying an image on a large screen, it is important to adjust the display settings correctly so that the picture looks clear and does not "twitch". In the settings of the Xiaomi phone in the "Translation" section or through the engineering menu, you can change the resolution of the output signal.
If you notice that your mouse cursor (when you plug in the keyboard) or finger movements are late, try lowering the resolution or frame rate. 1080p at 60Hz is the optimal mode for watching movies, which provides a balance between quality and smoothness.
⚠️ Warning: Installing too high resolution that doesn't support the TV LG, This can lead to a black screen or a message saying, "No signal." In which case, reset the broadcast settings on your phone.
Some Xiaomi models allow you to (force) desktop mode when connected to HDMI, which turns the phone interface into a kind of desktop computer, which is convenient for presentations or working with documents on the big screen.
💡
For games from your phone on your TV, be sure to use the “Game” mode in the LG TV image settings to reduce input lag.
Solving Connection Problems
Despite the simplicity of the technology, users often find that Xiaomi’s phone does not see an LG TV or the connection is constantly broken, most often the problem lies in the settings of the router, which divides devices into different subnets or blocks multicast traffic.
Try restarting your router, phone and TV. Make sure that Bluetooth is on on both devices, as it is often used to initially shake hands before transmitting a video stream over Wi-Fi. Also check if the router has a firmware update that could have knocked down settings.
If nothing works, you can use third-party apps from the Play Market, such as Cast to TV or AllCast, which use their own search algorithms and often cope where standard MIUI tools are powerless.
- 📡 Check that your phone and TV are connected to the same Wi-Fi frequency (2.4 GHz or 5 GHz).
- 🛡️ Turn it off. VPN On a smartphone, it can block the local network.
- 🔄 Update the Translation app and TV firmware to the latest versions.
💡
The stability of wireless broadcasting is 90% dependent on the quality of the Wi-Fi signal and the absence of physical barriers between it and devices.
