Connecting a laptop to a Xiaomi TV over Wi-Fi: all the ways and subtleties of setting up

Why is Wi-Fi Connection to Xiaomi TV Better Than Cable?

Wireless streaming from a laptop to a Xiaomi TV is not just a convenience, but often the only way to display an image without unnecessary wires. TV Q2 or Redmi Smart Fire TV), where HDMI-But the main advantage of Wi-Fi is mobility: you can move around a room with a laptop without losing connection, or you can quickly switch between devices.

But not everyone knows that Xiaomi TV has 4 wireless connections, and each is suitable for different tasks. For example, Miracast is ideal for dubbing the screen with minimal latency (important for games), and DLNA is better for streaming movies from the media library. And if you have a MacBook, you can not do without AirPlay. In this article, we will discuss all the options, from basic to advanced, and also solve typical problems like “no sound” or “picture is lying”.

Before you start, check out two key points:

• 📶 Both devices are connected to the same Wi-Fi network (or the TV is running in access point mode).
• 🔄 Updated software on TV (relevant for models older than 2020 – they often have bugs with Miracast).

Method 1: Miracast – Duplication of screen without delay

Miracast is a wireless broadcast standard built into most modern Xiaomi TVs (starting with 2018 Mi TV 4), which allows you to completely duplicate the laptop screen on a TV with a resolution of up to 4K@30Hz (up to 4K@60Hz on new models), the main plus is minimal latency (about 30-50 ms), which is critical for games or presentations.

To connect:

1. On TV: go to Settings → Connection and Sharing → Wireless projection (Miracast).
2. On a Windows 10/11 laptop: press Win + K → select your Xiaomi TV from the list.
3. On MacOS: Use built-in AirPlay (if your TV supports it) or third-party utilities like AirParrot.

If the TV is not displayed in the list of devices:

• 🔌 Check if the detection mode on TV is enabled (in Miracast settings).
• 🔄 Restart the router – sometimes it interferes with the double NAT.
• 🛠️ Update your Wi-Fi adapter drivers on your laptop (especially relevant for older Intel or Realtek models).

⚠️ Note: On laptops with AMD Ryzen (especially series) 4000/5000) Miracast may not work because of driver bugs. AMD Adrenalin or use an alternative method (DLNA).

Method 2: DLNA – streaming movies and music without screen duplication

DLNA (or UPnP) is a protocol for transmitting media files over a local network, and unlike Miracast, it doesn't duplicate a screen, but only sends a selected file (film, photo, music) to the TV, which is convenient if you want to watch video from a folder on your laptop without loading it with the entire desktop.

How to set up:

1. On TV: Open Media Player or Gallery → select DLNA.
2. On a Windows laptop: Enable Media Sharing in Control Panel → Network and Internet → Network Management Center → Additional Sharing Options. Add a file folder to the Media Library.

MacOS

VLC

Plex Media Server

Advantages of DLNA:

• 🎬 Supports almost all video formats (including.mkv,.flac).
• 📂 You can stream entire folders, not individual files.
• 🔋 Low power consumption (laptop is not loaded with rendering).

⚠️ Note: If the video is via DLNA slows down, try to reduce the bitrate in the player settings or convert the file to H.264 (Xiaomi TVs are not decoding well H.265/HEVC net).

💡

If the TV can't see DLNA-server, check if the Windows firewall is blocking it. Add an exception for ports 1900 (UPnP) and 8200 (DLNA).

Method 3: AirPlay for MacBook and iPhone owners

If you have a MacBook or an iPhone, the easiest way to stream is AirPlay. Most Xiaomi TVs in recent years (starting with the Mi TV P1 2021) support this protocol out of the box, the main advantage is automatic synchronization of sound and video without manual settings.

Instructions:

1. Make sure that the TV and MacBook/iPhone are connected to the same Wi-Fi network.
2. On TV: Settings → Connection and Sharing → AirPlay → turn on the option.
3. On MacBook: Open Control Center → Screen Mirror → Select your Xiaomi TV.
4. On iPhone/iPad: Swipe down for Control Point → Screen Duplication.

Features of AirPlay on Xiaomi TV:

• 🎵 Supports sound-only broadcasting (useful for music via Apple Music).
• 🔒 Requires code authorization (displayed on the TV screen when first connected).
• 📱 You can use it to continue watching from your iPhone to the big screen (like YouTube or Netflix).

Method 4: Third-party applications (for older models or advanced features)

If the built-in methods don’t work (like the 2016 Xiaomi Mi TV 3), you can use third-party apps, which often offer additional features like screen recording, annotations, or 4K@60Hz broadcasting even on older TVs.

Top.-3 tested applications:

• 🖥️ ApowerMirror – Supports Miracast, DLNA and even control TV from a laptop (there is a free version with watermarks).
• 🎮 Steam Link – optimized for games (minimum lag, support for gamepads).
• 📺 LocalCast (for Android) – broadcasts files from a laptop through a browser (works even without Wi-Fi, on the Internet) USB-cable).

How to set up ApowerMirror:

1. Download the app to your laptop (official website) and TV (via Google Play on Xiaomi TV).
2. Run the app on both devices and select Wi-Fi Connection.
3. On the laptop, enter PIN-code that will appear on the TV screen.
4. Select Mirror (Duplicate) or Extend (Screen Extension).

⚠️ Note: When using third-party apps, some Xiaomi models TV You may be able to block the broadcast due to security policy MIUI TV. Solution - disable Data Protection in TV settings (Settings) → Confidentiality).

Problem Solving: No sound, lags, connection cuts off

Even with the right setup, you can have some common errors, and here are the most common ways to fix them:

No sound when broadcasting:

• 🔊 Check if the correct audio output is selected on the laptop (PCM by sound icon) → Open sound parameters → Select the output device).
• 🔄 Restart the broadcast (sometimes the sound is “snatched” with a delay).
• 🛠️ Update your audio driver (especially if you use Realtek Audio).

The picture is slowing or tearing:

• 📶 Switch to 5 GHz in router settings (less interference).
• 🖥️ Reduce the broadcast resolution to 1080p (in Miracast settings or applications).
• 🚫 Close background programs on your laptop (especially torrents or cloud syncs).

3. Connection is permanently broken:

• 🔌 Check the router’s power – if it overheats, the signal may disappear.
• 📡 Reduce the distance between your laptop and router (or use a Wi-Fi repeater).
• 🔄 Reset the network settings on the TV (Settings) → Network → Reset).

💡

If the problem persists, try connecting via a USB cable (some Xiaomi TV models support USB-to-HDMI adapters) or use Google Chromecast as an intermediate device.

How to improve the quality of broadcasting: tips for gamers and moviegoers

If you're streaming games or watching movies in 4K HDR, the standard settings may not be as good as they are.

For games (minimum lag):

• 🎮 Use Miracast in Game mode (if available in TV settings).
• 📡 Connect your laptop and TV to your router via Ethernet (via an adapter) – this will reduce latency to 10-20 miss.
• 🔧 In the settings of the Wi-Fi adapter laptop turn on WMM (Wi-Fi Multimedia to prioritize traffic.

For films (maximum quality):

• 🎬 Choose a 10-bit color in the laptop graphics settings (for HDR).
• 📀 Use it. DLNA Direct reproduction (without transcoding).
• 🔊 Set the sound to PCM 5.1 (instead of compressed Dolby Digital, if the TV supports the).

To test the quality of the broadcast, you can use:

• 📊 Netflix Fast.com – Checking the speed of the connection.
• 🎯 Display Lag Test (on YouTube) – Measuring the delay.
• 🔍 VLC Media Player (include broadcast statistics: Tools) → Codec statistics).
