Synchronizing Xiaomiโs smartphone with LG TVs opens up new possibilities for viewing content, games, and device management. However, not everyone knows how to set up a connection correctly, especially if the device models are released over the years or run on different versions of firmware. In this article, we will discuss all the current ways of connecting, from wireless technologies to wired solutions, and also look at typical errors and their elimination.
Itโs important to consider that compatibility is not just brand-specific, but also supported standards. For example, older LG TVs (before 2018) may not support Miracast, and some Xiaomi models (like the Redmi Note 8 series) have restrictions on displaying images via USB-C โ HDMI without additional adapters. We tested all methods on current devices (2020-2026) and collected working circuits.
1. Preparation of devices before synchronization
Before you start connecting, make sure that both devices meet the minimum requirements:
- ๐ฑ Smartphone Xiaomi: version MIUI at least 12 (for stable operation of Miracast), connector USB-C Micro-USB (depending on the model).
- ๐บ Television LG: WebOS 4.0 and higher (Screen Share support), port availability HDMI or USB (wired).
- ๐ Wi-Fi network: both devices must be connected to the same network (for methods) DLNA and Google Cast).
Also check:
- ๐ Charge of the smartphone battery is not less than 30% (with wireless transmission, energy consumption increases by 20-30%).
- ๐ถ Wi-Fi signal โ not less than 70% (weak signal can cause lags when broadcasting video).
- ๐ Software updates: on TV LG Go to Settings. โ Support โ Software Update, on Xiaomi - Settings โ The phone. โ Updating the system.
Make sure your TV and phone are on the same Wi-Fi network|

Prepare cables/adapters (if you need a wired connection)-->
If youโre using a wired HDMI connection, pre-prepared an adapter (such as USB-C to HDMI for new Xiaomi models). Note that cheap, uncertified adapters may not support image output above 1080p.

If LG TV doesnโt see a smartphone on the Screen Share list of available devices, try rebooting both devices and repeating the search, often solving the problem of a temporary network failure.
2. Wireless synchronization via Miracast (Screen Share)
Miracast is a wireless image transfer standard supported by most modern devices, and on LG TVs it is implemented via Screen Share, and on Xiaomi via Wireless Display.
Instructions for connection:
- On LG TV: Open Settings โ Connect โ Screen Share. Select Miracast (or LG TV Plus on older models). Activate the Enable option.
Xiaomi
- Go to Settings โ Connection and Sharing โ Wireless Display.
- Turn on device search.
- Choose your LG TV from the list.
If the connection is not established:
- ๐ Restart your router โ sometimes conflicts IP-addresses block the connection.
- ๐ฑ On your smartphone, turn off Power Saving Mode โ it can limit Miracast background activity.
- ๐บ On the TV, check if the Hotel Mode is turned on, which blocks external connections.

3. Wired connection via HDMI or USB-C
The wired method ensures that images are transmitted consistently without delay, which is critical for gaming or watching high-resolution video.
- ๐ adapter USB-C to HDMI (for Xiaomi with a port USB-C) or micro-USB to HDMI (old-model).
- ๐บ Cable HDMI (version 1.4 or higher to support 4K).
Step-by-step:
- Connect the adapter to the smartphone, and the HDMI cable to the adapter and TV.
- On your LG TV, select the signal source (HDMI 1/2).
- On the Xiaomi smartphone, a request to select the display mode may appear โ choose Duplicate the screen or Expand the screen.
Important: Not all adapters support HDMI audio output. If audio is only coming from a smartphone, check the audio output settings in Settings โ Sound โ Xiaomi Output.
| Xiaomi model | Supported adapter | Max, permission. | Notes |
|---|---|---|---|
| Xiaomi 13/13 Pro | USB-C to HDMI (DisplayPort Alt Mode) | 4K@60Hz | Requires an adapter with a Realtek RTD2173 or similar chip. |
| Redmi Note 12 | USB-C to HDMI | 1080p@60Hz | The sound is transmitted only through a separate 3.5mm cable. |
| POCO X5 Pro | USB-C to HDMI (with external power) | 1440p@30Hz | When connecting to the TV, additional USB-power-line. |
Why canโt the TV see the smartphone through HDMI?
4. synchronization via Wi-Fi Direct (direct connection)
Wi-Fi Direct allows you to connect your smartphone to a TV without a router, creating a direct hotspot, a method that is useful if you don't have a home network or a weak signal.
How to set up:
- On TV. LG: Go to Settings. โ Network โ Wi-Fi Direct. Turn on the function and wait for the TV name to appear (for example, LG_WebOS_XXXX).
Xiaomi
- Open Settings โ Wi-Fi โ Wi-Fi Direct.
- Select the TV from the list and confirm the connection.
After a successful connection, you will be able to:
- ๐ท Transmit photos and videos through DLNA (Applications Gallery or Files on Xiaomi).
- ๐ฎ Use your smartphone as a remote (via the app) LG TV Plus).
- ๐บ Broadcast screen (if the TV supports Miracast via Wi-Fi Direct).
๐ก
Wi-Fi Direct consumes more power than a normal router connection. If you plan to broadcast long, connect your smartphone to charge.
5.Using Google Cast (Chromecast) and DLNA
If your LG TV supports Google Cast (built-in or via Chromecast), you can stream content from a Xiaomi smartphone through apps that support this feature (e.g. YouTube, Google Photos, Netflix).
How it works:
- Make sure that your TV and smartphone are connected to the same Wi-Fi network.
- Open a supported app (like YouTube) on Xiaomi.
- Click on the broadcast icon (๐ก) and choose your TV. LG.
To transfer local files (photos, videos, music) use DLNA:
- ๐ On your smartphone, open the Files or Gallery app.
- Select a file โ Share. โ DLNA.
- In the list of devices, select an LG TV.
โ ๏ธ Note: Some Xiaomi models (e.g. Redmi) 9A) Do not support Google Cast because of manufacturer restrictions, in which case use alternative methods such as Miracast or wired connection.
6. Controlling LG TV from Xiaomi smartphone
In addition to streaming content, you can use your smartphone as a remote for your LG TV.

- ๐ท Using a smartphone as a touchpad to navigate webOS.
If the app does not find the TV:
- ๐ Restart the TV and smartphone.
- ๐ถ Check if the TV is Ethernet Only (Settings) โ Network).
- ๐ In some models LG You need to manually allow external devices to connect to Settings โ General. โ Mobile management.
7. Solving common problems
Even with the right setup, errors can occur. Consider typical scenarios and how to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| TV doesn't see a smartphone in Miracast | Different Wi-Fi standards (for example, the TV supports only 2.4 GHz, and the smartphone is connected to 5 GHz) | Reconnect your smartphone to 2.4 GHz or set the router to compatible mode |
| The sound comes only from a smartphone when connected via HDMI | Adapter does not support audio transmission or HDMI-CEC mode is inactive | Check your smartphoneโs sound settings (Settings โ Sound โ Output โ HDMI) or use a separate audio cable |
| Lags and stutters when broadcasting video | Weak Wi-Fi signal or network congestion | Reconnect to 5 GHz network, disconnect other devices from router, or use wired connection |
| LG TV Plus app is not connected | Blocking the firewall or discrepancy of software versions | Update the TV app and firmware, temporarily turn off the firewall on the router |
โ ๏ธ Attention: On TVs LG If you have webOS firmware below 3.0, you may not have Miracast support, in which case you can use Google Cast or a wired connection.
8. Alternative synchronization methods
If standard methods donโt work, consider alternatives:
- ๐ฅ๏ธ Through USB (MTP/PTP): Connect your smartphone to your TV through USB And you can select file transfer mode, so you can view photos and videos, but you can't stream the screen.
- ๐ Cloud Services: Upload files to Google Drive or Mi Cloud, then open them on your TV via your browser or app LG Content Store.
- ๐ฎ Game consoles as a middleman: If you have a PlayStation or Xbox, connect your smartphone to your console via Remote Play and your console to your TV.
For advanced users, there is a possibility of customization ADB-Xiaomi TV connection, but this method requires root rights and technical knowledge.
๐ก
If you need to stream your smartphone screen to an LG TV without delay (for example, for streaming games), use a wired connection via HDMI with an adapter that supports DisplayPort Alt Mode. Wireless methods can produce latency of up to 100โ200 ms, which is critical for dynamic gaming.
