How to set up wireless projection on a Xiaomi Mi TV: the complete guide

Wireless screenplay on Xiaomi Mi TV opens up new possibilities for watching movies, presentations or games without unnecessary wires. However, many users face problems from lack of signal to constant connection breaks. In this article, we will discuss all the ways to configure wireless projection from standard Miracast to alternative protocols like AirPlay and Google Cast, and also explain how to fix typical errors.

It is important to understand that the functionality depends on the TV model and the firmware version of MIUI TV. For example, older versions (before MIUI TV 3.0) may not support AirPlay, and Miracast requires a compatible adapter on the source device. We tested the instructions on the Mi TV 4S, Mi TV Q1 and Mi TV A2 models - the results are summarized in the table below.

If you've tried to configure a projection before and you've encountered an error like "Device Unconnected" or "Device Unsupported," don't rush to blame the TV. 80 percent of the time, the problem is router settings or protocol conflicts, and then step-by-step solutions for each scenario.

1. Supported wireless projection standards on Xiaomi Mi TV

Xiaomi TVs support three main broadcast protocols, but their availability depends on the model and the region of the firmware.

• 📶 Miracast is a universal standard for Android/Windows, It works without the Internet (point-to-point). TV starting 2018 year-end.
• 🍎 AirPlay – a protocol from Apple, available on models with MIUI TV 3.2+ (Like Mi. TV Q2 2023) Requires connection to a single Wi-Fi network.
• 📱 Google Cast (Chromecast) – integrated into Google TV-firmware version (rarely found on Xiaomi, but possible through third-party apps).

To find out what protocols your TV supports, go to Settings → Connections → Wireless projection. If the list does not contain the right standard, check for software updates or use alternative methods (see section 5 for them).

Important nuance: some models of Mi TV for the Chinese market (CN-versions have limited support for AirPlay due to license agreements, in which case a change in the firmware region (instruction in section 6) will help).

Tip for gamers: if you use Miracast to stream games from PC, set the graphics settings resolution 1920×1080 at 60 Hz – this will reduce the latency to acceptable 30-50 ms.

3. AirPlay connection (for iPhone, Mac, iPad)
