How to Connect Your Computer to a Xiaomi TV over Wi-Fi: A Complete Guide to 2026

Why you need Wi-Fi between your PC and your Xiaomi TV

Wirelessly connecting your computer to a Xiaomi TV opens up possibilities that you could only dream of 5 years ago. Imagine editing a video on a PC, and the result instantly appears on the big screen of a Mi TV without a single wire. Or running a game with a keyboard and mouse, and the picture is streamed to a 55-inch display with 4K resolution. This is not fiction — this is the reality of modern technology.

But here's the catch: not all ways of connecting are equally efficient. Some face image delays (lags), some face connection breaks, and some can't find the right settings in the TV menu at all. In this article, we'll look at three working methods for connecting a PC to a Xiaomi TV over Wi-Fi, their pros and cons, and give specific recommendations for fixing typical problems. No water - only proven solutions for models from the Mi TV 4A to the Xiaomi TV Q2 2026.

Method 1: Miracast – native solution for Windows and Xiaomi

Miracast is a wireless image standard built into most modern devices, with its main advantage being minimal latency (30ms), which is critical for gaming and video watching. Xiaomi TVs have supported Miracast since the Mi TV 4 (2018), but there are nuances.

To activate the connection:

• 🖥️ On PC (Windows) 10/11): press Win + K, select your TV from the list. If you don't have one, check if Wi-Fi is on and if your Miracast card supports (the list of compatible adapters is available on Microsoft's website).
• 📺 Xiaomi. TV: Go to Settings. → Connection and sharing → Wireless display (Miracast) Enable the option and confirm the connection when a request appears.
• 🔄 If the connection is interrupted: try restarting the router (especially if it is running at 5GHz – Miracast is sensitive to interference).

Important: Miracast does not support default audio in some versions of Windows. To broadcast audio, you need to manually select the TV as the output device to Control Panel → Sound. Xiaomi TV may also need to turn off energy saving mode in the HDMI-CEC settings (Settings → System → Power Management).

Method 2: DLNA for media files without delay

If you want to stream movies, music or photos, DLNA is the perfect solution, because unlike Miracast, there's no screen duplication, and files are transferred directly from the PC to the TV, which reduces the network load and eliminates lag.

How to set up:

1. On Xiaomi TV, open the Media Player app (or Photo Gallery). Select DLNA from the side menu.
2. On PC (Windows): Enable Media Streaming in Control Panel → Network and Internet → Network Management Center → Additional settings.
3. Use programs like Kodi or Plex to manage your library easily, and they will automatically detect your TV on your local network.

DLNA limitations:

• 🚫 Does not support screen broadcasting (files only).
• 🎮 Not suitable for gaming – delay reaches 200-500 ms.
• 📁 Not all video formats are reproduced correctly (e.g., video formats, MKV with rare codecs may not open).

💡

If the TV doesn't see the PC on DLNA, check if the connection is blocked by the Windows firewall. Add an exception for ports 1900 (UPnP) and 8200 (DLNA).

Method 3: Third-party applications (AirDroid, ApowerMirror, Steam Link)

When built-in methods don't work, third-party solutions come to the rescue, offering additional features like controlling a TV from a PC or streaming games with minimal lag.

To install ApowerMirror or AirDroid Cast on Xiaomi TV:

1. Download. APK-Application file from official website (for example, ApowerMirror).
2. Transfer the file to the TV via a flash drive or cloud (such as Mi Drive).
3. Install through the File Manager → Install unknown applications (may need to enable developer mode).

Warning: Some applications (such as TeamViewer) may conflict with Miracast built-in. If after installing third-party software, wireless connection stopped working, reset the network settings on your TV (Settings → Network → Reset).

Typical errors and their solutions

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

⚠️ Note: If the Xiaomi TV does not appear in the list of available devices when connecting to Miracast, check if it is power saving mode in the Wi-Fi settings.

• 🔌 "No signal after connection: try manually selecting screen resolution on PC (e.g, 1920×1080@60Hz instead 4K). Xiaomi TVs sometimes incorrectly handle non-standard resolutions.
• 🎵 No Sound: Go to Windows Sound Settings → Conclusion → Select the device and specify the TV as the main one. TV Check if the sound is turned off in the settings HDMI-CEC.
• 🐢 Strong lags: If the router is dual-band, force both the PC and the TV to connect to a 5GHz network. Also close background applications on the PC (especially torrents or cloud synchronizations).
• 🔒 "Device not supported": update the TV firmware (Settings → On TV. → Software update) and video card drivers on PC.

If nothing helps, try an alternative method: connect your PC and TV to your router via a router. LAN-cable (yes, it's possible even without Wi-Fi!) Many Xiaomi models TV Ethernet bridge support, which provides a more stable connection.

Optimization of the broadcast quality

Even after you've successfully connected, the picture may not be perfect: low resolution, artifacts, slowdowns. Here's how to fix it:

Router settings:

• 📶 Switch to 5 GHz (if the router is dual-band).
• 🔄 Enable QoS (Quality of Service) and set the maximum priority for the MAC-PC and TV addresses.
• 🔌 Turn it off. WMM (Wi-Fi Multimedia), if microstuttering is observed.

PC settings:

• 🖥️ In the parameters of the graphics (for example, in NVIDIA Control Panel) select Adaptive Synchronization mode to reduce lags.
• 🎮 For games, reduce the resolution to 1080p — This will reduce the load on the network.
• 🔊 Turn off the sound effects in Windows (for example, “Sound Improvements” in speaker settings).

Xiaomi TV settings:

• 📺 Enable "Game Mode" (Settings) → Picture → Image modes) to reduce delay.
• 🔍 Turn off Auto Brightness and Noise Reduction – These Features Can Cause Artifacts.
• 🔄 Update the firmware to the latest version (relevant for Mi models) TV Q1/Q2, where Miracast bugs are fixed).

💡

For maximum stability, use a router with Wi-Fi 6 support (802.11ax) — It provides lower latency and better bandwidth for broadcasting 4K-content.

Comparison with wired connection (HDMI)

Wireless technology is convenient, but it has competitors – traditional ones. HDMI-Let's compare the two methods:

When to choose Wi-Fi:

• 🎬 To watch movies and TV series (DLNA).
• 📱 If the TV and PC are in different rooms.
• 🔄 For temporary broadcasting (e.g. presentation).

When is the best time to use HDMI:

• 🎮 For games (especially shooters where reaction is important).
• 🎥 For a viewing. 4K HDR-compressed content.
• 🔊 If you need multichannel sound (5.1, 7.1).

Hybrid: Some users combine both methods, such as connecting a PC to a TV over HDMI for gaming, and switching to Wi-Fi for everyday use (YouTube, movies).
