How to turn Miracast on your Xiaomi TV: a step-by-step guide

Xiaomi’s modern smart TVs offer users a wide range of multimedia experiences, including wireless transmission from a smartphone or tablet to a large screen. Miracast technology allows users to duplicate the screen of a mobile device without the need for extra wires and complex router settings.

Many Mi TV owners have difficulty finding the right option, as the name of the feature may differ from Android TV or PatchWall firmware versions, and understanding how a wireless display works will help avoid typical errors and ensure stable transmission of high-quality video signals.

In this article, we will take a closer look at the process of display activation, look at the differences between built-in apps and system settings, and look at diagnosing possible connection problems, learn how to properly configure Wi-Fi Direct and understand why your phone may not see TV.

What is Miracast Technology and How Does it Work for Xiaomi?

Miracast is a wireless multimedia content standard developed by the Wi-Fi Alliance. Unlike Chromecast, which requires a router and an internet connection to stream, Miracast technology creates a direct connection between devices via Wi-Fi Direct, which means that the image is transmitted directly from the phone's processor to the TV's decoder, bypassing the external network.

On Xiaomi TVs, the implementation of this technology can be called variously: “Wireless Monitor”, “Translation” or “Screen Mirroring”. The Android TV system, on which modern models run, has built-in support for this standard, but it requires the activation of the corresponding service in the menu to work correctly.

• 📡 Direct connection of devices without the involvement of the router provides minimal signal delay.
• 🎬 Support for video transmission in resolution up to 1080p and 4K depending on the TV model.
• 🔒 Encryption of connection WPA2 ensures the protection of transmitted data from interception.

It is important to understand that when using Wi-Fi Direct, data transfer speeds are limited by the antenna modules of both devices. If your smartphone supports only 802.11n, then high-bitret video transmission may be accompanied by compression artifacts.

⚠️ Attention: With active Miracast connection, the smartphone battery discharges much faster due to the high load on the processor and Wi-Fi module.

Preparation of equipment and compatibility check

Before you start setting up, you need to make sure your hardware meets the minimum requirements.While the technology is considered universal, older smartphone models may not support the Wireless Display feature.Check the specifications of your mobile device on the manufacturer's website or in specifications.

Make sure that your Xiaomi TV has the latest firmware installed. Outdated software may contain errors in the network modules. Go to Settings → About TV → System Update and check for new versions.

The optimal distance for initial pairing is not more than 3-5 meters. The presence of thick walls or powerful sources of interference (microwave ovens, running routers at the same frequency) can significantly impair the signal quality.

• 📱 The smartphone should support the Wi-Fi Display standard (usually Android 4.2).+ or iOS with AirPlay support through third-party apps).
• 📺 The TV should be on and running in Smart mode. TV.
• 🔋 It is recommended to connect the mobile device to charging for long sessions.

Step-by-step: activation through the system menu

The most reliable way to enable a broadcast is to use the built-in Android TV system. The interface may vary slightly depending on the regional version of PatchWall firmware or the global Android TV.

You first need to go to the main menu of the TV. With the remote control, press the home or me button. Find the gear icon or the Apps section, where system utilities often hide.

In the list of applications, find a program called Wireless Display or Cast. Run it. The screen will show a waiting window with the name of your TV and possibly a waiting window with the name of your TV, PIN-safety-code.

Path to function: Home → Applications → Wireless monitor (or Settings → Connected devices → Tranulation)

Now take your smartphone. In the notification curtain, look for the Translation button, Smart View button (on Samsung), Projection button (on Xiaomi), or Screen Replay button (on iPhone). In the list of available devices, select the name of your Mi TV.

💡

If the TV doesn’t appear on the list, try temporarily disabling Bluetooth on your smartphone — in rare cases, it will interfere with finding Wi-Fi Direct devices.

Once you select a device, you may see a request on your TV to confirm your connection, use the remote to press OK or Allow. The image from your smartphone should be displayed on the full screen.

⚠️ Note: Do not interrupt the process of pairing by abruptly turning off one of the devices, this can lead to the hanging of the network module of the TV.

Use of Xiaomi Mi Remote and third-party utilities

If the standard feature is unstable, you can use the official Xiaomi Mi Remote app or analogues, which is especially relevant for older phones where the system broadcast function is missing or does not work correctly.

Install the Xiaomi Mi TV or Android TV Remote Control app from the Google Play store. Both devices must be connected to the same Wi-Fi network (unlike a pure Miracast, it uses a local router network).

Launch the app and press the Connect button. After pairing, select the option "Screen Translation" or "Cast." This method often works more stable in noisy air conditions, as the router takes control.

• 📲 Convenient control of the cursor and keyboard directly from the smartphone screen.
• 🎞️ The ability to transfer videos from specific applications (YouTube, Netflix) through the Cast button inside the player.
• 🔊 Volume and multimedia control without using the main remote.

There are also third-party programs, such as AirScreen or ApowerMirror, that can be installed on the TV itself via the TV. APK-They emulate the AirPlay and Miracast receiver, expanding compatibility with Apple devices and other brands.

💡

Using intermediary applications via a Wi-Fi router often gives a more stable picture than direct Wi-Fi Direct, but increases the load on the home network.

Technology comparison: Miracast, Chromecast and AirPlay

Users often confuse different image protocols. Xiaomi TVs may have all three options available, but they work differently, and understanding the differences will help you choose the best use case.

Miracast creates a mirror image of the screen. Everything that happens on a smartphone (notifications, menu access, games) is displayed on TV. Chromecast (built into Android TV) works differently: the phone acts as a remote, sending a link to content, and the TV downloads it itself from the Internet.

AirPlay is Apple's proprietary protocol, which is natively built into new Xiaomi models, requires emulator installation on older models, and provides better optimization for iPhone and iPad devices.

The choice of technology depends on your tasks. Miracast is better for presentations or photo albums. For viewing YouTube or Netflix in high quality without draining your phone, you prefer to use the built-in Chromecast through the broadcast button in the application.

Diagnosing problems and fixing connection errors

Despite the simplicity of the technology, users may face problems: the TV can't see the phone, the image twitches or there's no sound. The first step should always be to reboot both devices.

A common cause of problems is Wi-Fi frequency separation. If your TV is connected to a 5GHz network and your phone is operating in the 2.4GHz band, the direct Miracast connection may not be established. Try to bring network settings to a common denominator or switch to a single band.

Check date and time settings. On some Xiaomi models, time desynchronization for more than 5 minutes blocks secure DLNA and Miracast connections. Set automatic synchronization over the Internet in the Settings menu → General → Date and time.

⚠️ Warning: Antivirus programs or firewalls on your smartphone can block outbound connections to broadcast the screen.

If there is an image but no audio, check the audio output settings in the app itself or in the TV system settings. Sometimes you need to manually switch the output device in Bluetooth settings and Xiaomi devices.
