How to stream a screen from a Xiaomi phone to an LG TV: all ways with instructions

Broadcasting from a Xiaomi smartphone to an LG TV opens up new possibilities for watching videos, games or presentations on a large screen. However, users often face compatibility problems: not all models support Miracast or Google Cast out of the box, and the settings of the menu on LG Smart TV may vary depending on the version of webOS. In this article, we will analyze all the current methods of broadcasting – from wireless protocols to wired connection via HDMI – and also explain how to avoid typical errors like “device not found” or image freeze.

It is important to understand that the success of the broadcast depends on three factors: the version of Android on your Xiaomi (starting with Android 9, the connection algorithms have changed), the LG TV model (the C1/C2 series OLED or the budget UK6200 have different chipsets) and the type of content (for example, Netflix or YouTube can block the broadcast due to DRM). If you tried to connect through Screen Mirroring and got an error, do not rush to blame the smartphone – the problem may lie in the settings of the router or the TV firmware.

We tested all the methods on devices from 2020 to 2026, from Redmi Note 11 to Xiaomi 14 Ultra and LG TVs on webOS 5.0-23. At the end of the article, you will find a compatibility table and answers to common questions, such as why sound is transmitted late or how to broadcast games without lags.

1. broadcast on Miracast (Screen Mirroring) - a universal way

Miracast is a wireless broadcast standard that supports almost all modern Xiaomi smartphones (starting with Redmi 5) and LG TVs (except for the oldest models on webOS 1.0-3.0). The main advantage of the method is the lack of dependence on the Internet: data is transmitted directly over Wi-Fi Direct, which reduces delays. However, the protocol has disadvantages: the maximum resolution is limited to 1080p, and if the signal is weak, it can “sprinkle” pictures.

To begin the broadcast:

• 📱 On the Xiaomi smartphone, open Settings → Connection and sharing → Screen broadcast (on older versions) MIUI The path may look like settings. → Additionally. → Wireless display).
• 🖥️ On TV. LG Go to Settings. → Network → Screen Share (or Miracast depending on the model) and activate standby mode.
• 🔍 From the list of available devices on your phone, select the name of your TV (usually displayed as a LG_XXXX webOS TV).
• ✅ Confirm the connection on both devices. If the screen is not duplicated, try turning off Bluetooth - it sometimes conflicts with Wi-Fi Direct.

On LG’s 2022-2026 TVs (QNED, OLED Evo series), the Miracast feature can be hidden under the name “Wireless Display” in the “All Settings → General → Devices” menu.

⚠️ Warning: If the image is slowing down after you connect, check if the phone is power-saving. Xiaomi automatically reduces the performance of the Wi-Fi module when activating the basic battery profile.

2. Google Cast (Chromecast) – for streaming video and music

If you don’t want to stream the entire screen, but only videos from YouTube, Netflix or Google Photos, it’s more convenient to use Google Cast. Unlike Miracast, this protocol requires both devices to connect to the same Wi-Fi network, but supports resolutions up to 4K HDR (on compatible LG models), and Xiaomi pre-installes the Google Home app, which makes it easier to set up.

Connection algorithm:

1. Make sure that the LG TV and Xiaomi smartphone are connected to the same Wi-Fi network (preferably at 5 GHz for stability).
2. Open an app that supports Google Cast (like YouTube) and tap the stream icon (usually in the upper right corner).
3. In the list of devices, select your TV LG. If it is not, check if Google Cast is enabled in TV settings: Settings → All settings → Network → Miracast/Google Cast.
4. To broadcast the screen, use the Google Home app in full: select the device → Broadcast the screen.

List of apps that support Google Cast on Xiaomi:

• 🎬 YouTube, Netflix, Disney+ (restrictively DRM)
• 🎵 Spotify, Google Music, Yandex Music
• 📷 Google Photos, Galery (MIUI)
• 🎮 Stadia, NVIDIA GeForce NOW (Only for games with cloud rendering support)

⚠️ Note: When streaming content from Netflix or Disney+ Google Cast TV LG This may show an error, "This content is not supported." L1. The solution is to use Miracast or wired connection.

3. HDMI wired connection for minimal delays

If you want maximum stability (for example, for games or videos in 4K@60fps), the best option is a wired connection via HDMI. This will require a USB-C → HDMI adapter (for new Xiaomi models) or Micro-USB → HDMI (for older smartphones like Redmi 4X).

Step-by-step:

1. Connect the adapter to your smartphone and connect it to your TV LG through HDMI-cable (preferably version 2.0 or higher).
2. On the TV, select the appropriate HDMI-Entry (usually automatically determined).
3. On Xiaomi smartphone, in the screen settings (Settings → Display → HDMI mode), select the resolution. For LG OLED, 1920×1080@60Hz or 3840×2160@30Hz is optimal (if the adapter supports 4K).
4. If the image doesn’t appear, try restarting your smartphone or changing the cable (cheap adapters often don’t transmit the signal).

💡

If you connect via HDMI on the TV screen appear stripes or flicker, try in the settings of the smartphone to turn off the function “Autolight” and set a fixed resolution (for example, 1080p instead of Auto).

4. DLNA broadcasting – for media files

DLNA (Digital Living Network Alliance) is a protocol for transferring media files (photos, videos, music) over a local network, unlike Miracast or Google Cast, it does not duplicate the screen, but only broadcasts selected files, which is suitable if you need to show photos from a gallery or a movie downloaded to your phone on LG TV.

How to set up DLNA on Xiaomi:

• 📲 Install a media server application on your smartphone, such as BubbleUPnP or Plex.
• 🌐 Connect your phone and TV to a single Wi-Fi network.
• 📺 On TV. LG Open the SmartShare app (or Media Player in new models) and select the source – your smartphone.
• 🎥 In the application on the phone, select a file for broadcast and click "Play on TV".

Advantages of DLNA:

• ✅ No sound delays (unlike Miracast).
• ✅ Supported formats MKV, FLAC, DTS (if the TV decodes them).
• ✅ You can stream files from an external drive connected to the phone.

Disadvantages:

• ❌ Does not work for screen duplication (media files only).
• ❌ On old TVs. LG (Until 2018, 10 bits may not be supported HDR.

5. Use of third-party applications (ApowerMirror, TeamViewer)

If standard methods don’t work (for example, on LG TVs without webOS or older Xiaomi smartphones), you can use third-party applications.

• 🔄 ApowerMirror – duplicates the screen with a delay ~100 ms, supports control from the TV.
• 🖥️ TeamViewer QuickSupport – allows you to broadcast the screen over the Internet (useful for remote assistance).
• 🎮 Steam Link – optimized for streaming games from PC, but works with smartphones.

Instructions for ApowerMirror:

1. Install the app on your smartphone and TV (for LG, download the version from the LG Content Store).
2. Connect both devices to the same Wi-Fi network.
3. On your phone, launch ApowerMirror, select "M" (Mirror) and scan QR-TV-code.
4. Allow access to the screen in the system window (on the MIUI 14 may need to include "Debugging by USB").

⚠️ Note: Apps like ApowerMirror often request permissions to access notifications and files. Don't install them from unverified sources - only use Google Play or use the app. LG Content Store.

💡

The app side is useful if standard protocols (Miracast, Google Cast) don’t work, but they can add additional delays and consume more smartphone battery.

6. Solving typical broadcasting problems

Even when you set it up properly, users are faced with errors, and here are the most common ways to fix them:

If none of these methods worked, check:

• 📶 Wi-Fi signal: TV and phone should be no further than 5 meters from the router.
• 🔄 Firmware version: on LG Update webOS to the latest version, on Xiaomi – check it out MIUI In Settings → The phone.
• 🛠️ Router settings: Turn off Client Isolation and turn on Multicast.

7. Comparison of broadcasting methods: which one to choose?

The choice of method depends on your task:

• 🎮 For games: the best option — HDMI-Adapter (minimum delays) If wires are intrusive, use Miracast, but with limited delays. FPS.
• 🎬 For movies: Google Cast (if content is supported) or DLNA (locally).
• 📱 For screen duplication (social networks, presentations): Miracast or ApowerMirror.
• 📸 For photo/music: DLNA or USB-drive (if the TV supports exFAT).

💡

For LG’s 2020 and later TVs (webOS 5.0+), Google Cast is a top priority, as it supports HDR and surround sound. The older models (2017-2019) are more reliable with Miracast.
