Wi-FiThis allows you to not only watch movies, but also show presentations or play games on the big screen.
Ecosystem Xiaomi offers several proven protocols for interacting with the operating system Windows 10, each with its own unique characteristics. In this article, we'll cover in detail how to set up a connection, what tools to use, and what to do if devices can't see each other on the local network.
Preparatory stage and network requirements
Before you begin setting up, you need to make sure that both devices - your laptop or desktop PC, as well as your TV Xiaomi Mi TV - connected to the same wireless network. This fundamental condition, without which DLNA or Miracast technology won't work. If your router supports the 5 GHz band, it's best to use it for transmitting heavy video streams without lag.

You can update your drivers through Device Manager or by downloading the latest version from the motherboard manufacturer's official website.
⚠️ Note: Some routers have a client isolation feature. If enabled, devices on the Wi-Fi network will not be able to see each other, even if they are on the same subnet. Disable this feature in your router settings.

It's worth noting that using Miracast puts a strain on your computer's Wi-Fi network. If the signal is weak, image artifacts or audio desync may occur. This isn't a problem for viewing static presentations, but for dynamic video, a wired connection or other methods are recommended.

Troubleshooting common connection problems and errors
Despite the simplicity of the technology, users often encounter the problem that the computer does not see the TV Xiaomi or the connection keeps dropping. First, check to see if your antivirus or Windows Firewall is blocking network discovery.
A common problem is different Wi-Fi frequencies. If the router broadcasts both the 2.4 GHz and 5 GHz bands under the same name (Smart Connect), devices may be "scattered" across different bands, preventing a direct connection. Try temporarily separating the networks or forcing both devices to connect to the 5 GHz band.
