Wireless streaming via Miracast and WiDi
Miracast technology (known as WiDi from Intel) allows you to transfer an image over Wi-Fi Direct without having to connect to a router. This is a built-in feature in the Android TV operating system that Xiaomi TVs are equipped with. To connect to Windows 10 and 11, open the notification center and select Connect.
The computer will start looking for available devices. When your Xiaomi Mi TV appears on the list, click on it to pair, and the TV screen may have a request for permission to connect, which must be confirmed by the remote, which is convenient because it does not require extra wires and works at a distance of up to 10 meters.
The quality of wireless broadcasting depends on the load of the wireless range. If you notice a sound out of sync or a “twitch” of the picture, try to free the channel or switch to a frequency of 5 GHz. Also, consider that the laptop and TV should support the standard Wi-Fi Direct.
Broadcasting via Google Chrome (Chromecast built-in)
Because Xiaomi TVs are powered by Android TV, they have built-in support for Google Cast technology, which allows you to stream the contents of the Google Chrome browser tab or the entire desktop directly to the big screen, ideal for browsing the web, YouTube or presentations.

⚠️ Note: Chromecast laptop and TV must be on the same Wi-Fi network, and different subnets (e.g. guest and main) can block device detection.
Use of DLNA protocol and Mi Remote application
The DLNA protocol is primarily designed to transfer media files (video, photos, music) rather than duplicate screens in real time.It’s a great way to watch a downloaded movie from a laptop hard drive on a Xiaomi TV without copying files to a flash drive.
To activate the broadcast, make sure that the Windows settings are network detectable. Open the file in a standard player (such as Windows Media Player or Movie & TV), right-click and select Transfer to your device. Select your Xiaomi TV from the list.
Alternatively, use the proprietary Mi Remote app or third-party DLNA-Servers like Serviio or Plex provide more flexible content library settings and allow you to stream formats that a standard Windows player may not recognize.
Why does DLNA not play some formats?
Sound setting and screen resolution
A common problem when connecting is the lack of sound on the TV when it continues to play on your laptop. In Windows 10/11, click on the speaker icon in the tray, select the output device, and click on the name of your TV (often displayed as a TV model or Intel/NVIDIA Audio).
To adjust the image, go to Screen Settings, where it is important to set the native resolution of the TV array, usually 1920x1080 (Full HD) or 3840x2160 (4K), and incorrect resolution can lead to cropping the edges of the picture or black stripes.
Note the refresh rate. Most Xiaomi TVs support 60Hz, some models up to 120Hz. Set too high a frequency that the panel does not support will result in a black screen with the message "Signal is not supported."
