Connecting a smartphone to a Xiaomi TV opens up a lot of possibilities, from watching photos on the big screen to streaming games with minimal latency. However, many users face compatibility problems, unstable connection or simply do not know which method to choose. In this article, we will analyze all the current methods of synchronization (including hidden functions of MIUI and Google Cast), compare them on speed, transmission quality and power consumption, and give a checklist to diagnose typical errors.
Xiaomi TVs (Mi TV 4/5, Redmi Smart TV, Xiaomi TV A Pro) are PatchWallโs own firmware, which sometimes conflicts with standard Miracast or DLNA protocols. We tested all methods on 2020-2026 models and found out which ones work stable and which require additional settings. If you tried to connect and saw errors like โDevice not supportedโ or โNo signalโ at the end of the article there is a section with solutions.
1. Wi-Fi Direct (Miracast) connection โ no router
This is the most versatile way, which works on all Android 5.0+ smartphones and Xiaomi TVs on PatchWall 3.0 and later. The advantage is that there is no dependence on Internet speed, since the connection is built directly between devices. However, the method has limitations: the maximum screen resolution is 1080p at 30 Hz (on some models, 4K@24Hz is possible).
How to turn on:

- ๐ฑ On the phone: Settings โ Connected devices โ Screen transfer (Cast) (on iPhone: Control Point) โ Screen duplication).
