How to transfer the screen from Xiaomi to LG TV: all working ways

Broadcasting from a smartphone to a big TV screen opens up new possibilities, from watching high-quality movies to showing photos to friends or giving presentations. However, Xiaomi users often face difficulties when trying to connect to LG TVs – especially if models are released in different years or use different wireless transmission protocols.

In this article, we will discuss all the current methods of broadcasting – from standard Miracast to alternative solutions like Google Cast and wired connection via HDMI. You will learn how to configure the connection on Redmi phones, POCO and flagship Xiaomi 13/14 series, as well as on LG TVs with webOS 4.0-23. Particular attention is paid to solving typical problems: audio delay during broadcasting via Wi-Fi Direct is eliminated by changing the router channel by 5 GHz.

If you've tried to connect devices without success, don't blame the technology. 80 percent of the time, the problem is with bad network settings or outdated firmware, and we'll detail every step so that even a beginner can set up a stream without errors.

1. Device Preparation: What to Check Before Connecting

Before you start setting up your broadcast, make sure both devices meet the minimum requirements. On the side of the Xiaomi smartphone, you must have MIUI 12 or later (older versions may not support Miracast). LG TVs with webOS 3.0 and below often do not support modern protocols - in this case, you will need an external adapter (for example, Google Chromecast).

Key points to check:

• 📱 Version. MIUI: Open the Settings. → The phone. → Version. MIUI. If version is older than 12, update the system through Settings. → Update of the PO.
• 📺 WebOS version: On the remote LG press Settings (⚙) → All settings → General information → Information on TV.
• 🔄 Shared Wi-Fi network: Both devices should be connected to the same network (preferably at 5GHz for minimal latency).
• 🔋 Battery charge: Make sure your smartphone has at least 30% charge – the broadcast is actively consuming energy.

Pay special attention to power saving settings on Xiaomi. Activated Battery Mode → Energy saving can block background data transmission, which will lead to a broadcast interruption. Turn it off temporarily or add a broadcast app to exceptions.

💡

If your LG TV doesn’t support Miracast but has an HDMI port, use a USB-C/HDMI adapter (for new Xiaomi) or Micro-USB/HDMI (for older models) to ensure a stable connection without delay.

Method 2: Wireless streaming via Miracast (Wi-Fi Direct)

Miracast is a wireless screen standard built into most modern devices. It doesn't require an internet connection, but both devices must support the technology. On Xiaomi, the feature is called the Wireless Display, on LG, it's called Screen Share or Miracast.

Step-by-step:

1. On TV. LG: 📺 Press the Input (or Source) button on the remote. 🔍 Select Screen Share (in some models – Wi-Fi Direct). ⚙️ Turn on the option and wait until the TV starts searching for devices.

Method 2: Broadcasting via Google Cast (Chromecast)

If your LG TV supports Google Cast (built-in or through an external Chromecast device), this method will provide a more stable connection than Miracast.The main advantage is the ability to stream only content (like YouTube or Netflix videos) rather than the entire screen, saving battery life.

How to set up:

1. Connect the Chromecast (if external) to the HDMI port on your TV and switch to the appropriate signal source.

💡

Google Cast is better than Miracast for streaming video, but requires a compatible app. Use Miracast or HDMI to stream the entire screen (games, presentations).

Method 3: Wired connection via HDMI

If wireless methods are unstable or you need minimal response time (for example, for games), use a wired connection. USB-C/HDMI (for the new Xiaomi, or Micro-USB/HDMI (The cost of the adapter is from 500 before 2000 RUB depending on support 4K@60Hz.

Advantages of wired connection:

Note that some adapters require additional power via a USB port. If the image does not appear, connect the adapter to the charger or USB port on the TV.

💡

For games (like Call of Duty Mobile or Genshin Impact), use HDMI only – a delay over Wi-Fi will make the game uncomfortable.

5. Method 4: Broadcasting through third-party applications

If the standard methods don't work, you can use third-party applications.

• 📱 ApowerMirror – supports both Miracast and connectivity USB (requires installation of the server part on the PC).
• 📺 LG TV Plus - the official application from LG, But it doesn’t work on all Xiaomi models.
