Wirelessly transferring images from your computer to the big screen of Xiaomi TV opens up new possibilities for work, entertainment and presentations. However, many users face difficulties when connecting for the first time: the TV does not see the PC, the picture slows down, the sound disappears. In this article, we will examine all the current ways of connecting, from standard Miracast to alternative protocols like DLNA and AirPlay, and also explain how to avoid typical errors.
Xiaomi TVs (Mi TV A, Mi TV Q, Redmi Smart TV, etc.) are particularly featured in their flexible MIUI TV firmware, which supports most modern wireless standards. But even with such a technique, it is important to set up your computer and the TV properly. We will look at step-by-step instructions for Windows 10/11, macOS and even Linux, and we will also give recommendations for optimizing the connection for stable operation without delays.
1. Preparing Xiaomi TV for wireless connection
Before connecting devices, make sure your Xiaomi TV is ready to receive the signal, and most connectivity problems are due to disabled features or outdated software.
First thing you need to do is check the TV firmware version.
- Open the settings (cog on the remote).
- Go to About TV. โ Updating the system.
- If a new version is available, install it, which is especially important for Mi TV 4S and older models, where early firmware had Miracast bugs.
Then activate the necessary protocols:
- ๐บ Miracast: Settings โ Connections โ Wireless projection (turn on the slider).
- ๐ต DLNA: Settings โ Network and access โ Media server (enable and name the device).
- ๐ AirPlay (for AirPlay) macOS/iOS): Settings โ Apple AirPlay (available on models with Apple AirPlay) MIUI TV 3.0+).
๐ก
If the menu does not have the item "Wireless projection", update the firmware or reset the TV network settings to factory (Settings โ System โ Network Reset).
Also make sure that the TV and your computer are connected to the same Wi-Fi network. If you use a dual-band router (2.4 GHz + 5 GHz), you better choose 5 GHz - this will reduce delays when broadcasting video. To check the network on the TV, go to Settings โ Network โ Network Status and see the current connection.
2. Connection via Miracast (Windows) 10/11)
Miracast is a wireless screen transfer standard supported by most modern devices that allows you to duplicate or expand your computer screen to your TV without additional software, but this method has nuances: for example, on Xiaomi TV older than 2019, you may need to manually adjust.
Instructions for Windows:
- On your computer, press Win + K (or open Settings โ System โ Project on that computer).
- Select Connect to the wireless display.
- In the list of available devices, find your Xiaomi TV (the name will match the name in the settings of the TV).
- Confirm the connection on the TV (a request with a code will appear).
If the TV is not on the list:
- ๐ Reboot both devices.
- ๐ถ Check that your computerโs Wi-Fi adapter supports Miracast (in Device Manager, find the adapter and check its properties).
- ๐ง Update your graphics card drivers (especially relevant for Intel) UHD Graphics and AMD Radeon).
Wi-Fi on TV and PC enabled|Both devices in the same network|Miracast activated in settings TV|PC graphics card drivers updated-->
On Xiaomi TVs with MIUI TV 2.0 and below, Miracast may not work as smoothly as you would expect, in which case you should use alternative methods (DLNA or HDMI cable).
3. Alternative methods: DLNA and AirPlay
If Miracast is not suitable (for example, due to delays or lack of support), you can use other protocols.
DLNA is suitable for broadcasting media files (movies, music, photos), but does not allow you to duplicate the computer screen.
- On the TV, turn on the Media Server (see section 1).
- On your computer, open Explorer, find the file folder, right-click and select Transfer to the device โ [Name of your Xiaomi TV].
- On the TV, open the Media Player or Gallery app โ the files will appear there.
AirPlay (for MacBook or iPhone owners) allows you to broadcast the screen with minimal delays.
- On the TV, turn on Apple AirPlay in the settings.
- On a Mac, open Control Center โ Screen Mirror and select your Xiaomi TV.
- On iPhone, swipe down for Control Point, tap Screen Duplicate and select the TV.
| Method | Supported OSs | Delay. | Quality. | Supplementary SO |
|---|---|---|---|---|
| Miracast | Windows 10/11, Android | Medium (50-100 ms) | Up to 4K@30Hz. | No. |
| DLNA | Anybody. | No (files only) | Original | No. |
| AirPlay | macOS, iOS | Minimum (20-50 ms) | Up to 4K@60Hz. | No. |
| Steam Link | Windows, Linux | Low (30-70 ms) | Up to 1080p@60Hz | Yeah (Steam) |
For gamers, an interesting solution will be Steam Link, an app that allows you to stream games from your PC to your TV, install it on your TV via Google Play (if the model supports) and follow the instructions in the program.
4. Solving common problems

๐ก
For maximum stability, use a router with Wi-Fi 6 (802.11ax) support โ this will reduce latency to 20-30 ms even when broadcasting 4K.
6. Connection through third-party programs
If the built-in tools don't work, you can use specialized applications, which often offer additional features, such as broadcasting only a single window or recording a screen.
1. ApowerMirror (Windows/macOS)
- ๐ฑ It supports both Miracast and its own protocols.
- ๐ฎ Allows you to control the TV from a computer (mouse/keyboard).
- ๐ฐ The free version has watermarks.
2. TeamViewer (for remote control)
