Transferring images from a smartphone to a large TV screen is a challenge that users face when watching videos, games or presentations. Xiaomi devices (including the Mi, Redmi and Poco lines) support several ways to wirelessly and wiredly connect to TV, but not all of them are equally convenient. In this article, we will discuss 5 working methods taking into account the features of MIUI firmware and the hardware limitations of TVs.
The main problem that users face is protocol incompatibility or lack of Miracast support on older TV models. We tested all methods on Xiaomi Mi TV (4K/8K), Samsung QLED, LG OLED and budget models with Android TV to give clear recommendations. If your TV does not support modern standards, no problem: there are solutions for such cases in the article.
1. Wireless transmission via Miracast (Screen Mirroring)
The most versatile way for modern TVs is to use Miracast technology, built into MIUI. It allows you to duplicate the screen without wires, but requires support from TV. On Xiaomi Mi TV function works out of the box, and for other brands may need additional software.

If the connection fails, try:
- 🔄 Reboot both devices.
- 📶 Connect your smartphone and TV to the same Wi-Fi network (even if Miracast works without the Internet, sometimes it helps).
- 🛠️ Update the TV firmware (relevant for Android) TV Android 9 and below).
2. Wired connection via HDMI (MHL or USB-C)
For stable transmission without delay (relevant for games or video in 4K), it is better to use a wired connection. Xiaomi smartphones support image output via:
- 🔌 USB-C → HDMI (for models with Snapdragon 8xx Dimensity, starting with the Redmi Note 10 Pro).
- 🔄 MHL-Adapter (for older Micro-USB devices, such as Redmi Note) 4X).
The connection will require:
| Type of smartphone | Required adapter | Max, permission. | Notes |
|---|---|---|---|
| Xiaomi 11/12/13, Redmi K40/50 | USB-C → HDMI (DisplayPort Alt Mode) | 4K@60Hz | Requires original Xiaomi cable or certified |
| Redmi Note 9/10, Poco X3 | USB-C → HDMI (without DisplayPort) | 1080p@30Hz | Possible artifacts at high load |
| Redmi 4X/5A, Mi A1 | MHL-adapter (Micro-USB) → HDMI) | 1080p@30Hz | External power is required for the adapter |
⚠️ Attention: With cheap adapters, you may have trouble recording sound, the image will be transmitted and the sound will remain on your smartphone, in which case the adapter with support will help. HDMI ARC or a separate 3.5 mm audio output.
