Wireless display doesn’t connect to Xiaomi TV: A complete troubleshooting guide

Xiaomi's wireless screen broadcast technology from phone to TV should work out of the box -- just activate Miracast or Wi-Fi Direct, and the image from the smartphone will appear on the big screen. The TV doesn't detect the device, the connection breaks after a few seconds, or the screen is broadcast with artifacts. TV, So in the firmware of the smartphone, and sometimes to blame external factors – from interference in the network to incompatibility of protocols.

In this article, we will analyze all possible scenarios why you can not connect a wireless display to the Xiaomi Mi TVs. TV 4A/4S/4X/5/5X/6 (including Google models TV), We'll also give you step-by-step instructions for diagnosing and fixing problems, and we'll focus on the Android developer's hidden settings. TV, which the manufacturer does not advertise, but which often solve the problem with connection.

If you've tried standard methods before (reboot, reset) and nothing has worked, don't rush to bring the TV to the service. 90% of the time, the problem is solved software-based, without interference with the hardware, the main thing is to correctly identify the source of the problem.

1. Checking the basic conditions for wireless broadcasting

Before digging deep into the settings, make sure the minimum requirements for Miracast or Wi-Fi Direct work are met. Ignoring them is the most common reason for the phone’s “invisibility.”

First, both devices must support the same broadcast protocol:

• 📱 Smartphone: Miracast (Android 4.2)+) Wi-Fi Direct (Android 4.0)+). The iPhone uses AirPlay, which Xiaomi TV It doesn’t support the native (Apple needs to support it) TV third-party).
• 📺 TV: Mi TV The 4 Series and newer support Miracast by default. TV (Like Mi. TV Q2 2023) may need to enable the option manually.

Second, check the hardware compatibility:

💡

On Xiaomi TVs until 2018 (for example, Mi) TV 3S) Wireless broadcasting only works through third-party adapters, as they do not have a built-in Miracast module.

Thirdly, the physical conditions:

• 📶 The distance between the phone and the TV should not exceed 5-7 meters (ideally 2-3 meters), walls, furniture and other obstacles weaken the signal.
• 🔋 The charge level of the phone should be above 20% – with low charge, Android limits background processes, including screen broadcasting.
• 🔄 Both devices must be connected to the same Wi-Fi network (for Miracast this is not necessary, but is recommended for stability).

⚠️ Attention: If you are using VPN Or proxies on your phone, turn them off before you connect. These services can block local network protocols needed for broadcasting.

• 🔍 Find the option “Wireless debugging” or “Miracast is always on” and turn it on.

If the menu does not have the option “Wireless display”, it means:

• 🔄 Your firmware is outdated - update the TV through Settings → On TV. → Updating the system.
• 🛠️ The TV is disabled Wi-Fi Direct module at the kernel level (solved by resetting to factory settings).
• 📦 You have a model without Miracast hardware support (e.g. Mi). TV 3 or Mi TV 4 without module 802.11ac).

Check the version. MIUI TV (Must be 3.0 or newer)|Activate the “Wireless Display” in the settings|Enable the "Allow All Devices" mode»|Restart the TV after the changes|Update the firmware to the latest version-->

3.Setting up a smartphone to stream on Xiaomi TV

The problem may lie in your phone’s settings, too, and even if the TV is set up correctly, the smartphone can block the broadcast due to energy savings, background limitations, or conflicts with other apps.

6. Alternative methods of screen broadcasting

If Miracast and Wi-Fi Direct don't work hard, use alternative broadcasting methods, which may be less convenient, but often save in critical situations.

Method 1: Applications for mirroring (without root)
