Modern Xiaomi TVs support many ways to wirelessly and wiredly sync with smartphones, from standard Miracast to proprietary solutions like Mi Share. However, not all users know how to properly configure the connection to avoid image delays, audio breaks or compatibility problems. This article covers all current methods of connection (including hidden features for older models) with the features of the MIUI TV and Google TV firmware on Xiaomi, Redmi and POCO devices.
We will not only look at basic scenarios (like screen duplication via Screen Mirroring), but also advanced options such as using a TV as a monitor for games from a smartphone or streaming content in 4K HDR without loss of quality, with particular attention to solving common errors (such as code 10 or โdevice not supportedโ) that occur when connecting devices on Android 13/14 or iOS.
Important: instructions are relevant for Xiaomi Mi TV 4A/4S/4X (2018-2023), Mi TV 5/6/7 series, Redmi Smart TV X, as well as flagship models Mi TV Q1/Q2/Q2 Pro with MediaTek and Amlogic processors. If your model is older than 2017, check the section on alternative methods of connection.

3 Method 2: Wired connection via HDMI or USB-C
If wireless methods are unstable (for example, due to a weak Wi-Fi signal), use a direct wired connection, which is important for gamers who stream games from their phone to the big screen, or to watch videos in maximum quality without compression.
Option 1: Through the USB-C โ HDMI adapter (for smartphones with DisplayPort Alt Mode support):
- ๐ฑ Connect the adapter to the port USB-C of the smartphone.
- ๐ฅ๏ธ Connect the adapter to the TV cable HDMI (use the port HDMI 2.0 or HDMI 2.1 for 4K@60 Hz).
- ๐ On the TV, select the appropriate signal source (HDMI 1/2/3).
Option 2: via MHL- adapter (for older smartphones with Micro-USB):
Relevant for devices up to the 2018 year (for example, Xiaomi Mi 5 or Redmi Note 4). You will need a MHL โ HDMI adapter and external power (USB- charging).
| Adapter type | Supported smartphones | Max, permission. | Delay. |
