Why you need a second screen on Xiaomi

Using the second screen on Xiaomi devices opens up new opportunities for multimedia, work and gaming. For example, you can duplicate your smartphone screen on your TV to watch movies on a big screen, expand your workspace to make documents easier to work with, or even stream games with minimal latency, HDMI-Mi Share adapters and branded Mi Share make this process simple, but not always obvious to beginners.

In this article, we will discuss three main ways to connect the second screen on Xiaomi devices (Redmi smartphones, POCO, Mi 11/12/13, and also Mi TVs. TV). You will learn how to set up wireless duplication via Miracast, wired connection via HDMI-port USB-C → HDMI, And also how to use proprietary solutions like Mi Share to stream content, and we'll focus on device compatibility and the common bugs that interfere with the second screen.

Importantly, not all Xiaomi models support extended screen mode (when the second monitor works as an extension of the first one). Most smartphones are limited to duplication - that is, both screens display the same picture, with the exception of some flagships (for example, Xiaomi 13 Ultra) and TVs with MIUI TV.

Method 1: Wireless Duplication via Miracast (Wi-Fi Direct)

Miracast technology allows you to transfer an image from your smartphone to your TV or monitor wirelessly using direct Wi-Fi Direct. This method works on most Xiaomi devices (starting with MIUI 9) and does not require a connection to a router. The main condition is that both devices must support Miracast (on TV this can be called Screen Mirroring, Wireless Display or WiDi).

To activate Miracast on Xiaomi smartphone:

1. Open Settings → Connection and Sharing → Wireless display.
2. Turn on the Wireless Display slider (on some models – Transmit to TV).
3. In the list of available devices, select your TV or monitor.
4. Confirm the connection on both devices (entry may be required) PIN-code).

If the TV is not on the list, check:

• 🔄 Update firmware on both devices (outdated versions) MIUI Android TV They may not support Miracast).

Method 2: Wired connection via HDMI or USB-C

For stable image transfer without delay, it is better to use a wired connection. Modern Xiaomi smartphones (starting with the Redmi Note 10 and Mi 11) support video output via the USB-C port using a USB-C → HDMI adapter. This method guarantees minimal latency and supports a resolution of up to 4K@60Hz (depending on the adapter and smartphone model).
