Introduction: Why you need a wireless screen broadcast
Wirelessly transferring images from Xiaomi Redmi to your TV via Wi-Fi offers a range of possibilities, from watching movies on the big screen to showing presentations or streaming games, and the main advantage of this connection is the lack of wires and freedom of movement: you can hold your phone in your hands without being tied to sockets or cables.
But not everyone knows that wireless streaming on Redmi works differently depending on the TV model, MIUI version, and even the type of Wi-Fi network. For example, older TVs without Miracast support will require additional devices (like Google Chromecast), and new Smart TVs from Samsung or LG can connect directly through embedded protocols. In this article, we will discuss all the current ways, from standard MIUI features to workarounds for complex cases.
It is important to consider the technical nuances: signal latency (latency) when broadcasting over Wi-Fi can reach 100-300 ms, which is critical for games, but almost imperceptible when watching video. Also, some methods (for example, DLNA) transmit only media files, not the entire screen, we will discuss each option in detail to select the best one.
Connection via Miracast (built-in MIUI function)
Miracast is a wireless screen broadcast standard supported by most modern Xiaomi Redmi (starting with the Redmi Note 5) and Smart TV. It doesnโt require internet โ itโs enough that the phone and TV are connected to the same Wi-Fi network (or create a direct access point).
To activate Miracast on Redmi:
- ๐ฑ Open the Settings. โ Connections and sharing โ Screen transmission.
- ๐ Turn on the search for available devices โ the TV should appear in the list (like Samsung) TV (Miracast? LG TV (Screen Share)).
- ๐ Select your TV and confirm the connection on both devices.
If the TV is not available:
- โ๏ธ Make sure that Screen Mirroring is on the TV (on the Network menu) โ Screen mirroring or similar).
- ๐ถ Check that the phone and TV are connected to the same Wi-Fi network (or the phone creates an access point to which the TV is connected).
- ๐ Restart both devices โ sometimes it solves detection problems.

3. Smart View (for Samsung TVs)

5.DLNA: broadcast media (not the whole screen)
If you only need to transfer photos, videos, or music (not the entire screen), use the DLNA protocol. It's built into MIUI and works with most Smart TVs.
