Wirelessly connecting your computer to a Xiaomi TV via Wi-Fi: all ways

Wirelessly streaming a screen from a computer to a Xiaomi TV is a convenient way to turn a large screen into a monitor for work, games or viewing content without unnecessary cables. However, many users face problems: connection is interrupted, picture is slowed, the TV simply does not see the PC. In this article, we will examine all the current ways of connecting, from embedded technologies Miracast and DLNA to specialized applications like Steam Link or AirPlay.

It's important to understand that the choice of method depends on your tasks: Miracast is for office work, for streaming movies, DLNA, and for games you'd better use Steam Link or Moonlight. We'll also compare the speed, latency and compatibility of each option so you can choose the best one. If you've tried to connect but you didn't succeed, there's a section at the end of this article that addresses common bugs, including problems with drivers, networking and settings on the TV.

1. Preparing Xiaomi TV for wireless connection

Before you connect devices, make sure your Xiaomi TV (Mi TV 4/4S/4A/5/5X/Q1/Q2 and later) supports the right protocols. Most modern models are equipped with Miracast (for screen duplication) and DLNA (for media streaming), but budget options can be limited.

First, check the firmware version: go to Settings → About TV → Software Update. If the version is older than MIUI TV 3.0, upgrade the system - older versions often lack Miracast support or have connection bugs. Also make sure that the TV and computer are connected to the same Wi-Fi network (preferably at 5 GHz for lower latency).

• 📺 Models with support for Miracast: Mi TV 4S 55", Mi TV Q1 75", Redmi Smart TV X and newer.
• 🚫 Models without Miracast: some budget Mi TV 4A (check in the settings).
• 🔄 Software Update: If the TV can’t see the computer, update the firmware first.

⚠️ Note: If your Xiaomi TV is released before 2018, it may not support Miracast at the hardware level. DLNA External devices like Google Chromecast.

Method 1: Miracast - Duplication of screen without wires

Miracast is a wireless image transfer standard built into most modern Xiaomi and Windows TVs (starting with version 8.1) that allows you to completely duplicate your PC screen on your TV with minimal latency (about 30–50 ms), which is suitable for office tasks or watching videos.

To connect:

1. On TV: open Settings → Connection and Sharing → Wireless Display (Miracast).
2. On your computer (Windows 10/11): press Win + K, select your TV from the list.
3. Confirm the connection on both devices.

If the TV is not on the list, check:

• 🔌 Network Connection: Both devices must be on the same Wi-Fi network (not via Ethernet!).
• 🖥️ Video card drivers: update them through Device Manager or manufacturer’s website (NVIDIA/AMD/Intel).
• 🔄 Miracast Mode: Some Xiaomi TVs need to enable the “Allow Connection” option manually.

Xiaomi TVs with MIUI TV 4.0+ have a hidden setting to reduce Miracast latency: go to Settings → For Developers → Turn off Miracast hardware acceleration (can help with lags).

3. Method 2: DLNA – streaming media files over a local network

If you want to stream only movies, music, or photos, rather than the whole screen, use DLNA, which allows you to open media files from your computer directly on your TV over a local network, and the main advantage is that there are no delays, since the file is transmitted in its entirety, not streaming.

Instructions for Windows:

1. Turn on DLNA on your TV: Settings → Network → DLNA.
2. On PC, open Options → Networks & Internet → Sharing Options and enable Shared Media Access.
3. Select the movie/music folders for public access.
4. On the TV, open the Media Player or Gallery app and select your computer from the list of devices.

⚠️ If the TV cannot see the computer DLNA, Check the Windows firewall, it can block access. Add an exception for the 1900 ports (UDP) 8090 (TCP).

4. Method 3: Steam Link – games and applications without lags

For gamers, the best option is Steam Link, the official app from Valve that streams games from PC to TV with minimal delays (10-30 ms with good Wi-Fi). The app is available on Google Play for Xiaomi TVs on Android TVs (Mi TV 5 series and later).

How to set up:

1. Install Steam Link on your TV via Google Play.
2. On PC, install Steam and enable Settings → Remote Access → Enable Steam Link.
3. Connect the gamepad to the TV (by Bluetooth or USB).
4. Run Steam Link on your TV and follow the pairing instructions.

For better performance:

• 🎮 Use a wired gamepad (Bluetooth adds latency).
• 📶 Connect your PC over Ethernet and your TV to 5GHz Wi-Fi.
• ⚙️ In Steam Link settings, select Performance Priority and disable Optimize for Video".

💡

If the game slows down, reduce the broadcast resolution in the Steam Link settings to 1280×720 – this will reduce the load on the network.

5. Method 4: AirPlay (for iPhone/Mac owners)

If you have an Apple device (MacBook, iPhone or iPad), you can use AirPlay to stream the screen to a Xiaomi TV, but here’s the caveat: natively, Xiaomi TVs do not support AirPlay – you will need third-party software.

Connection options:

1. Through AirScreen: Install AirScreen from Google Play on your TV. Launch the app and select AirPlay Mode. On Mac/iPhone, swipe down to call Control Point → Screen Duplication.

For maximum stability, we recommend:

• 📡 Use a mesh router (e.g., Xiaomi Mesh System) for an uninterrupted signal.
• 🖧 Connect your PC over Ethernet and your TV over 5GHz Wi-Fi.
• 🔧 Regularly update the TV firmware and drivers on the computer.

💡

For high-resolution (4K) games and videos, use Steam Link or Moonlight – these are optimized for low latency, unlike Miracast.
