How to watch movies from your computer on a Xiaomi TV via Wi-Fi: all the working methods

Streaming movies from your computer to the big screen Xiaomi TV Wi-Fi is a convenient way to enjoy your favorite content without unnecessary wires and external devices. However, many users encounter problems: video lags, audio lags behind the picture, and some formats don't play at all. In this article, we'll look at all current methods content transfer - from built-in functions Miracast And DLNA to third-party applications like Steam Link or Plex.

Feature of TVs Xiaomi (series Mi TV A2, P1, Q2 etc.) — support for most modern wireless protocols, but setting them up isn't always intuitive. We'll explain in detail how to connect without lag, what codecs is better to use for 4K content, and why it is sometimes easier to use USB cable instead of Wi-Fi. And if you like games, we'll show you how to launch Steam on a big screen with minimal lag.

Important: All methods have been tested on TVs. Xiaomi With MIUI TV version 3.0 and later. If you have an older firmware, some features may be missing - update the software via Settings → About TV → System Update.

1. Method: Miracast (wireless screen mirroring)

Miracast — a wireless screen transfer standard built into most modern Xiaomi TVIt allows mirror the image from your PC to your TV in real time, but with some limitations: a delay of up to 100 ms (noticeable when viewing dynamic scenes) and possible artifacts with a weak Wi-Fi signal.

To connect:

  • 📺 On TV: Open Settings → Connection and Sharing → Wireless Display and enable the option.
  • 💻 On PC (Windows 10/11): Click Win + K, choose yours Xiaomi TV from the list and confirm the connection.
  • 🔄 If the image doesn't appear, reboot your router—sometimes double NAT or an IP address conflict is interfering.

Miracast supports resolution up to 1920×1080 at 60 Hz, but for 4K will be required Wi-Fi 6 (the router and TV must support it). Also note that sound is transmitted only via HDMI — If you use Miracast, connect speakers or a soundbar to the TV separately.

⚠️ Note: On some models Xiaomi TV (For example, Mi TV 4S 55") Miracast works unstably with laptops based on Intel Wi-Fi 6 AX200In this case, use the alternative methods from the following sections.

2. Method: DLNA (media streaming)

DLNA — a protocol for transferring media files over a local network. Unlike Miracast, it doesn't duplicate the screen, but sends the file itself to the TV, where it plays back using the built-in player. This reduces the load on the PC and reduces latency, but requires the TV to support your video formats (e.g., MKV With H.265 may not be playable).

How to set up:

  • 📺 On TV: Open the app Media player (or Gallery on new models) and select DLNA.
  • 💻 On PC:
    • 🪟 Windows: turn on Streaming media V Control Panel → Network Settings → Advanced Sharing Settings.
    • 🐧 Linux: install MiniDLNA or Rygel via terminal.
  • 📂 Place movies in a folder General videos (or any other shared over the network).
Video format Support on Xiaomi TV Recommendations
MP4 (H.264) ✅ Yes The best choice for DLNA
MKV (H.265) ⚠️ Partially May slow down on weaker models (for example, Mi TV 4A)
AVI (Xvid) ✅ Yes Supported, but without hardware acceleration
MOV (ProRes) ❌ No Use Miracast or convert to MP4

If the video does not play, please check codecs in the file properties (right-click → Properties → Details). For problematic formats, use Plex (see section 4) - it transcodes files on the fly.

📊 Which protocol do you most often use for video transfer?
Miracast
DLNA
Steam Link
Plex
Another

If you have installed Steam on PC, you can use the application Steam Link for streaming not only games, but also any movies. This method provides minimal latency (up to 30 ms) and supports 4K@60fps, but requires a powerful processor on the PC (from Intel Core i5 or Ryzen 5).

Instructions:

  1. Install Steam Link to TV via Google Play Store (If you don't have it, download the APK from the official website.) Valve).
  2. Launch Steam on PC and turn it on Settings → Login → Steam Link Settings.
  3. Connect a gamepad or use Big Picture Mode to control the mouse.
  4. Open the movie in any player (for example, VLC or MPC-HC) - the image is automatically broadcast on TV.

Advantages of the method:

  • 🎮 Gamepad support (including Xbox And DualSense).
  • 🔊 HDMI audio transmission (including DTS:X And Dolby Atmos).
  • 🖥️ Ability to run any Windows applications on TV.
⚠️ Attention: When broadcasting 4K HDR-content via Steam Link can be observed video card overheating on laptops. Monitor temperatures in HWMonitor or lower the resolution to 1440p.

Check your Wi-Fi speed (minimum 50 Mbps) | Update your graphics card drivers | Close background programs | Connect your PC to the router via cable (optional) -->

4. Method: Plex (media server with transcoding)

Plex - This media server, which not only streams files, but also automatically converts them into a format supported by the TV. For example, if your Xiaomi TV does not reproduce MKV with AC3, Plex transcodes the audio to AAC on the fly. The downside is that transcoding requires a powerful processor (from 8th Generation Intel i3).

Setting:

  1. Download Plex Media Server from the official website and install on your PC.
  2. Add movie folders to the library (Add Library → Movies).
  3. Install the application Plex to TV via Google Play.
  4. Log in with the same account on both devices.

Tips for optimization:

  • 📶 If your Wi-Fi is weak, enable it in the server settings Bitrate limitation (for example, before 20 Mbps).
  • 🔧 For 4K HDR In the transcoding settings, select Original Quality (without conversion).
  • 📁 Use a folder structure Film (year)/Film.mkv — Plex will automatically pull up covers and descriptions.
How to speed up transcoding?

If Plex is slow when converting, try:

1. Enable hardware acceleration in the server settings (Settings → Transcoding → Use hardware acceleration).

2. Install NVIDIA NVENC (for video cards GTX 10xx and newer) or Intel Quick Sync (for integrated graphics Intel UHD).

3. Limit the number of simultaneously transcoded streams to 1-2.

Method 5: Local web server (for advanced users)

If you need to transfer files without installing additional programs, you can run local web server directly to your PC. The TV will open movies through the browser as streaming video. This method is suitable for MP4 And WebM, but does not support subtitles.

Instructions for Windows:

  1. Open Command line on behalf of the administrator.
  2. Go to the movie folder:
    cd C:\Films
  3. Start Python's built-in web server (install Python 3 if you don't have it):
    python -m http.server 8000
  4. On your TV, open a browser and enter the address http://[your_PC_IP]:8000 (For example, http://192.168.1.100:8000).

For Linux/macOS use the command:

python3 -m http.server 8000

Advantages of the method:

  • 🚀 No dependence on proprietary protocols.
  • 🔒 Works even if DLNA is disabled in the router.
  • 📱 You can open files not only on TV, but also on your smartphone.
⚠️ Warning: Do not use this method for MKV or AVI — the TV browser does not support their playback. Only MP4/WebM with codecs H.264/VP9.

6. Troubleshooting: lags, no sound, device not found

If the broadcast is not working or is delayed, please check the following:

Problem Possible cause Solution
The video is lagging Weak Wi-Fi signal Use range 5 GHz or connect your PC via cable
No sound Miracast only transmits video. Connect audio via HDMI ARC or use DLNA
The TV doesn't find the PC Disabled WSD or UPnP in the router Enable it in your router settings Multicast And IGMP
Artifacts in 4K Not enough bandwidth Reduce the bitrate to 25 Mbps or use HEVC

If the problem persists, try:

  • 🔄 Restart your router and TV (sometimes resetting the DLNA cache helps).
  • 📡 Switch to a different Wi-Fi channel (for example, from 6 to 11) in the router settings.
  • 🛠️ Update your Wi-Fi adapter drivers on your PC (especially important for Realtek).

FAQ: Frequently Asked Questions

The best option is to install Netflix And YouTube directly to the TV via Google Play.

Why does video lag behind audio when streaming via Wi-Fi?

This is a typical problem. asynchrony of streams, caused by:

  • Overloading the PC processor (if transcoding is used in Plex).
  • Unstable ping on the network (check through ping 192.168.1.1 -t (in the command line).
