You want to display a Samsung Galaxy image on a big screen on a Xiaomi TV, but don't know which method to choose? This task seems simple only at first glance: protocol compatibility, Android and MIUI versions, as well as hardware limitations can create unexpected difficulties. Unlike duplication between devices of the same ecosystem (for example, Samsung DeX on Samsung TV), the Samsung + Xiaomi bundle requires a special approach.
In this article, we will analyze 5 proven ways of screen duplication - from wireless protocols (Miracast, Google Cast) to wired solutions (HDMI, USB-C). Youβll learn which method gives you the minimum latency for games, how to get around typical connection errors (like βDevice Not Supportedβ), and why Smart View sometimes refuses to work with Xiaomi Android-based TVs. TV. We also compare the quality of the image transmission in Full resolutions. HD and 4K different models.
1. Wireless duplication via Miracast (native method)
Miracast is a wireless screen standard built into most modern Samsung smartphones (starting with the Galaxy S8) and Xiaomi TVs (Mi TV A2, P1, Q2 and later), the main advantage of the method is the lack of dependence on the Internet: the connection is installed directly over Wi-Fi Direct.

If Miracast is permanently disabled, try turning off the HDMI Auto Disconnect option in Xiaomi TV settings β it can interrupt the connection.
The response rate for this connection is ~50β80 ms (depending on the model), which is suitable for watching video, but not always comfortable for dynamic games. For comparison, a wired connection via HDMI gives a delay of 10β30 ms.
2.Using Smart View (Miracast alternative for Samsung)
Samsungβs Smart View feature is a proprietary shell above Miracast, but with additional settings.It supports not only screen duplication, but also the broadcast of individual applications (for example, YouTube or Netflix) without displaying the smartphone interface.

- Turn on the option to Show devices without Miracast (if the TV is not displayed).
- Select a Xiaomi TV from the list and confirm the connection.
- From the Additional Settings menu, you can select the mode: Duplicate screen β full display of the interface; sound only β for using the TV as Bluetooth speakers; Game mode β reduces latency (available on the Galaxy S22 and later).
β οΈ Attention: On Xiaomi TVs with Android TV 10+ You may need to allow access to Developer Settings (enable Wi-Fi Debugging in Settings) β On TV. β Software version, pressing 7 times on the line with the build number).
3.Duplicate through Google Cast (Chromecast)
If Miracast fails or crashes, the alternative is Google Cast, built into Xiaomiβs Android TVs (Mi TV 4S, Mi TV Q1 and later), which uses a local Wi-Fi network rather than a direct connection.
