Wireless projection on Xiaomi TV: how to turn on Miracast and broadcast the screen from your phone or PC

The principle of wireless projection on Xiaomi TV

Wireless projection technology allows you to stream a smartphone, tablet or computer screen onto a large screen of a Xiaomi TV without using cables, based on two key standards: Miracast (for Android/Windows) and AirPlay (for Apple devices), both of which use direct data transmission over Wi-Fi, which provides minimal latency — critical for gaming or watching video.

Xiaomi Mi TV 4/5, Redmi Smart TV and Android TV 9.0+ models support Miracast out of the box. However, three conditions are required to work smoothly: device compatibility, network settings and up-to-date TV firmware. For example, Xiaomi smartphones on MIUI 12+ automatically detect TVs from the same ecosystem, making it easier to connect.

It is important to understand the difference between screen duplication (mirroring) and content broadcasting (e.g. YouTube or Netflix), in the first case, all actions from the phone are repeated on TV, in the second case, only video stream, which saves battery life.

Preparing Xiaomi TV for wireless projection

Before setting up Miracast, make sure your Xiaomi TV meets the minimum requirements:

• 📺 Model: Mi TV 4A/4S/4X/5, Redmi Smart TV X or newer (2018 year of release and later).
• 🔄 Firmware: Android TV 9.0 or higher (check in Settings) → On TV).
• 📶 Network: Connecting to Wi-Fi at 5 GHz (recommended) or 2.4 GHz (may slow down).
• 🔋 Power: The TV must be plugged into the socket – with a low battery charge (if the TV is portable), Miracast shuts down.

If your TV is not visible in the list of available devices for projection, reset network settings:

1. Go to Settings → Network and Internet → Wi-Fi.
2. Select your network and click Forget.
3. Connect again by entering the password.
4. Restart the TV through Settings → Device → Reboot.

Miracast performance depends on the TV model. TV 5 Pro supports permission to 4K@60Hz delayed ~30 MS, whereas Redmi Smart TV A55 limited 1080p@30Hz and delay ~60 For games, it is better to use a cable connection (HDMI).

Step-by-step: how to turn Miracast on Xiaomi TV
