You want to stream your favorite movie, stream or photos from Xiaomi to a big TV screen, but don’t know how to do it wirelessly? Wi-Fi video transmission is a convenient way to mirror the screen or stream content, but the setting often raises questions. In this article, we will analyze all the current methods for Xiaomi smartphones (including models on MIUI 14/15 and HyperOS), compare their pros and cons, and give recommendations for eliminating typical problems.
From standard protocols like Miracast and Google Cast to specialized applications, each method has its own nuances. For example, on Xiaomi phones with a Snapdragon 8 Gen 2+ processor, Miracast broadcasts are more stable than on devices with Dimensity 9000+ due to driver optimization. If your TV does not support modern standards, you will have to use workarounds. Next, a detailed guide with step-by-step instructions, comparison tables and tips for optimizing broadcast quality.
Preparation of the phone and TV: what to check before broadcasting
Before you set up a connection, make sure that both devices meet the minimum requirements, which will save time and eliminate errors such as "device not found" or "no sound".

- 🔄 Network Connection: TV and phone must be on the same Wi-Fi network (for Google) Cast/DLNA) Or in each other's range (for Miracast), if you use a guest network, the broadcast may not work.
- 🔊 Audio output: To transmit sound over Miracast on some TV models (e.g. Samsung) QLED 2021-2022) I need to turn on the option. HDMI-CEC.
⚠️ Note: If your TV is released before 2018, it may not support Miracast in 5GHz mode.In this case, force the phone to switch Wi-Fi to 2.4GHz (c Settings) → Wi-Fi → Additionally).
Method 2: Miracast (Wireless Display)
Miracast is a built-in wireless screen protocol supported by most modern Xiaomi phones and TVs, with the main advantage of minimal latency (up to 50 ms), which is critical for high-resolution games or video, but quality depends on the power of the phone's processor and the stability of Wi-Fi.
Instructions for MIUI/HyperOS:
- Open Settings → Connection and Sharing → Wireless projection (on some models, the path may differ: Settings → Additional → Wireless Display).
- Activate the Wireless projection slider and wait for the available devices to be found.
- Select your TV from the list. If it is not available, click Update or check the TV settings (see section 1).

| Max, permission. | 4K@30fps | 1080p@60fps | 1080p@30fps |
| Demands the Internet. | No (Wi-Fi Direct) | Yes. | Yes. |
| Sound support | Yes. | Yes. | Depends on the player. |
Method 2: Broadcasting via Google Cast (Chromecast)
Google Cast is an alternative to Miracast, which works through apps (e.g. YouTube, Netflix, Google Photos) and unlike mirroring, it only transfers content, not the entire screen, which reduces the CPU load, which is ideal for streaming videos, but is not suitable for games or presentations.
How to set up:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- Open a supported app (like YouTube) and find the Cast icon (usually in the upper right corner).
- Select your TV from the list. If it's not available, check if Google Cast is on TV (see below).
- Start the video and it will start playing on the TV.
Google Cast activation on your TV:
- 📺 Android TV/Xiaomi TV: Settings → Devices → Broadcasting → Turn on.
- 📺 Samsung (Models 2020)+): Install Google Home app and add TV as a device.
- 📺 LG (WebOS: Install Chromecast Built-in via LG Content Store.
💡
If the video slows down when streaming via Google Cast, try lowering the resolution in the app settings (e.g. YouTube: Settings → Quality → 720p) this will reduce the load on the network.
List of popular apps with support for Google Cast:
- 🎬 YouTube, Netflix, Disney+ — streaming.
- 📷 Google Photos – View photos and slideshows.
- 🎵 Spotify, Yandex Music – Music broadcast.
- 📺 Twitch, Kodi – streams and local media files.
4. Method 3: Transfer of files over DLNA
DLNA (Digital Living Network Alliance) is a protocol for sharing media between devices on a local network, and unlike Miracast, it doesn't stream data, but the files themselves (video, photos, music) that avoid lags, but DLNA doesn't support broadcasting screen or sound from games.
How to set up on Xiaomi:
- Install a file manager with DLNA support, such as Mi File Manager (built into MIUI) or Solid Explorer.
- Open the manager, select the file and click Send → DLNA (or Translate).
- Select the TV from the list. The file will open in the standard TV player.
Table setting:
- 📺 Xiaomi. TV: Settings → Network → DLNA → Turn on.
- 📺 On Sony Bravia: Home → Media → DLNA.
- 📺 Nana LG: Install the SmartShare app.
Why can't DLNA work?
⚠️ Note: When transmitting video through DLNA The sound may be delayed until 1-2 It's OK for the protocol, but it's critical for subtitled movies. Use external subtitles or sync them in a TV player.
Method 4: Party of the broadcast application
If the built-in methods don’t work (for example, on older TVs), third-party software will help. We tested 5 popular apps and selected the best ones for Xiaomi:
| Annex | Type of broadcast | Pluses | Cons |
|---|---|---|---|
| ApowerMirror | Screen mirroring | Works without root, low latency | Advertising in the free version, time limit |
| Screen Mirroring (by Google) | Miracast/DLNA | Simple interface, integration with Google Cast | Not all TV is supported |
| LocalCast | DLNA/Chromecast | Support for subtitles, bitrate settings | Paid version for 4K |
| Miracast Display | Miracast | It works on old Android | Requires manual IP setup |
Instructions for ApowerMirror (recommended for games and videos):
- Download the app to your phone and computer/TV (if you have Android TV).
- Connect both devices to the same Wi-Fi network.
- On your phone, launch ApowerMirror, press M (mirror) and select the TV.
- Confirm the connection on TV (entry may be required) PIN-code).
💡
The app side is useful if your TV doesn't support Miracast or Google Cast, but remember: they can collect data about your media files.
6. Problem Solving: Why the Broadcast Doesn't Work
If the screen is not broadcasting or the video is slowing down, use this instruction:
- 🔌 No connection: Restart your phone and TV. Check if your phone's Wi-Fi Direct is enabled (Settings) → Wi-Fi → Extra. Turn it off. VPN Proxies – they can block local connections.
- 🎞️ Video lags: Reduce the broadcast resolution in Miracast settings (if available). Switch the router to 5GHz (if supported). Close background apps on your phone (especially instant messengers and games).
- 🔊 No sound: Check if the TV or the player is turned off. For Miracast, activate the audio transmission option in the broadcast settings on your phone. For Google Cast, update the app that streams through.
💡
If the broadcast is permanently interrupted, try connecting your phone to your TV via a USB-OTG cable (if the TV supports MHL), which will give you a more stable connection than Wi-Fi.
7. Comparison of methods: which way to choose
The choice of method depends on your task:
- 🎮 For games: Use Miracast (minimum delays) or ApowerMirror (if Miracast is not supported).
- 🎬 For movies/streams: Google Cast (via Google Cast) YouTube/Netflix) or DLNA (locally).
- 📸 For photos: Google Cast (via Google Photos) or Miracast (for slideshows).
- 🏠 For older TVs: App side (LocalCast, Screen Mirroring) or USB-OTG.
If you need to stream and record a screen at the same time, use the combination of ApowerMirror (for broadcast) + Screen Recorder (for recording), which is relevant for streamers or creating educational videos.
