How to connect the Xiaomi Mi TV 4 to the phone: all the ways

Connecting a Xiaomi Mi TV 4 to a smartphone opens up a lot of possibilities, from broadcasting a screen for presentations to controlling the TV as a remote control via an app. However, many users face compatibility problems, connection errors or simply do not know which way to choose. In this article, we will discuss all the current methods of synchronization from wireless protocols to wired connections, and give recommendations for solving typical problems.

It’s important to understand that the Mi TV 4 (including 4A, 4S, 4X) supports different technologies depending on the year of release and firmware version. For example, 2018-2019 models may not have built-in Miracast, but work consistently through Google Cast (if PatchWall 3.0+ is installed).

If you don’t have a Xiaomi router, turn on the “AP Isolation” option in your Wi-Fi settings – this often solves the device detection problem.

2. Screen broadcasting via Miracast (Wi-Fi Direct)

Miracast is a wireless image transfer standard without connecting to a router. Xiaomi Mi TV 4 supports it at the firmware level, but there are nuances: on Android smartphones, the feature is called Wireless Display or Smart View, and on the iPhone it is absent (Apple uses its own AirPlay protocol, incompatible with Miracast).

Typical problems and solutions:

• 🔴 TV not visible in device list: restart both devices and check that TV is on Detection mode.
• 🟡 Image Lag: Reduce the resolution of the broadcast in Miracast settings or connect to the router at 5 GHz.
• 🟢 No sound: on some firmware you need to manually select the sound source in the TV settings (Settings) → Sound. → Source).

On the 2018 Mi TV 4 models, Miracast only works after updating the firmware to version 2.3.65+. You can check the version in Settings → About TV.
