You want to stream a video with Xiaomi, play mobile games on the big screen or give a presentation, but you don’t know how to connect your smartphone to your TV? This problem is solved in 5-10 minutes – if you know the right settings and nuances of compatibility. Depending on the model of your TV (for example, Mi TV, Samsung or LG) and smartphone (Redmi Note 12, POCO X5, Xiaomi 13T, etc.), there are up to 5 ways to duplicate the screen – from wireless protocols to wired connection.
In this article, we will discuss all the current methods of broadcasting the screen, including hidden MIUI functions, avoiding common errors (for example, “no signal” or “device not found”) and optimizing image delay. Particular attention will be paid to the compatibility of Miracast and Wi-Fi Direct protocols with TVs of different brands – a key point that is often missed in standard instructions, and you will learn how to bring the screen to TV without lags for games or streaming in 4K.
1. Wireless broadcast via Miracast (without router)
Miracast is the most versatile way to duplicate Xiaomi’s screen on a TV without wires or extras, and works on a peer-to-peer basis, meaning it doesn’t require a single Wi-Fi network, and the main condition is that your TV must support Miracast (most models after 2016 are yes).
How do you check for TV support? Go to your network settings and look for items like Screen Mirroring, Wi-Fi Direct, or Wireless Display. On Mi TV, this is called Settings → Connection → Cast.

- ❌ Not all apps support audio broadcasting (for example, Netflix or YouTube may block audio due to the fact that the audio is not available). DRM).
2. Connect via Wi-Fi Direct (with or without a router)
Wi-Fi Direct is an alternative to Miracast, which often works more stable on older Xiaomi models (like the Redmi 5/6). Unlike Miracast, it can use a router as an intermediary, which sometimes solves compatibility problems.
Instructions:
- On the TV, turn on Wi-Fi Direct (on Mi TV: Settings → Wi-Fi → Wi-Fi Direct).
- On your smartphone, go to Settings → Wi-Fi → Additional → Wi-Fi Direct.
- Select the TV from the list and connect. Enter PIN-code, if required (usually 0000 or 1234).
- Once connected, go back to Screen Projection on your phone and select TV.
