Xiaomi’s Android TVs offer a huge opportunity for multimedia entertainment, and one of the most popular features is wirelessly transferring images and sound from a smartphone or tablet to a large screen. Miracast technology allows users to stream the contents of a mobile device’s screen in real time without delays and the need for an Internet connection using a direct Wi-Fi connection.
Many owners of equipment face difficulties in the initial setup, because in the interface of the TV this feature can be called differently, for example, Wireless Display or Wireless Monitor. Understanding the principles of DLNA and Wi-Fi Direct will help you not only quickly set up a connection, but also troubleshoot possible problems. In this article, we will discuss the connection process in detail, consider the nuances for different versions of firmware and answer frequently asked questions.
The quality of the broadcast depends on the stability of the wireless signal and the version of the protocols supported. If you want to enjoy high-resolution 4K video without artifacts, it is important to consider the distance between the devices and the presence of interference in the air. Let's start by getting your equipment ready for work.
Preparation of equipment and compatibility check
Before you start setting up, you need to make sure that your equipment is technically ready to go. Most modern models of Xiaomi Mi TV and Redmi TV have built-in Miracast module, however, on older versions of firmware or in budget models with reduced functionality, you may need an external console.
It is critical that both devices, the TV and the smartphone, are in the same wireless range. While Wi-Fi Direct technology allows direct connection, a shared Wi-Fi router hotspot is often recommended for initial setup and stable operation, especially for devices operating in the 2.4 GHz band, where interference from neighboring networks is high.
Check the operating system version on your Xiaomi TV. Go to the settings menu and find the About TV section. If the software version is significantly outdated, it may be that the wireless display function is not working correctly or is not on the menu.
⚠️ Note: When using the Miracast function, the smartphone battery can discharge much faster due to the high load on the Wi-Fi module and processor. It is recommended to keep the mobile device charged or connected to a power source during long sessions.
Activation of the wireless display function on the TV
The first step is to turn on the TV-side reception mode. Android TV interfaces may vary depending on the PatchWall shell version or pure Android version. You need to find the app that's responsible for the broadcast, most of the time it's called Wireless Monitor, Wireless Display or Cast.
Find this app in the list of installed programs on the home screen or in the Apps folder. Once you run, you will see a waiting screen with your TV's name, which will appear in the list of available devices on your smartphone. Some Xiaomi models require manually enabling this feature in network settings.
To do this, go to Settings → Network and Internet. You may need to activate the Wi-Fi Direct switch or allow other gadgets to detect the device. If you use the external console Mi Box, make sure that it switches to the correct HDMI input.
- 📺 Open the main menu of the TV and find the app section.
- 📡 Launch the Wireless Monitor app or similar.
- 🔌 Make sure that the Wi-Fi module is active and visible for search.
- 📱 Write down the name of the device that is displayed on the screen (it will be necessary to connect).
☑️ Checking before connection
Connecting Android Smartphone to Xiaomi TV
The process of connecting an Android smartphone is the most naive, because the Miracast protocol is built into the system. However, manufacturers often change the name of this feature (MIUI/HyperOS) It’s called “Translation”, on Samsung it’s called Smart View, and on other devices it can be called “Screen projection” or “Translation».
Open the notification curtain on your smartphone and find the appropriate icon. If it is not available in quick access, go to Settings → Connected devices → Broadcast. The system will start searching for available devices within range. Once you see the name of your Xiaomi TV, click on it.
You might see a request on your TV to confirm your connection, use the remote to press OK or Accept, and then the image from your smartphone will be duplicated on the big screen, and it's important to note that when you use Wi-Fi Direct, the data rate can be lower than when you connect via a router.
If the image quality is low or there are jerks, try to approach the router or switch your smartphone to a 5GHz network if your router supports dual-band operation. Also make sure that the phone does not run heavy background loads.
💡
To reduce latency when playing games or watching videos, close all unused apps on your smartphone to free up RAM and Wi-Fi channel.
Broadcast from iPhone and iPad (AirPlay)
Apple device owners use the AirPlay protocol, which is also supported by modern Xiaomi TVs. Unlike Miracast, AirPlay provides a more stable connection and better picture quality, but requires both devices to be on the same Wi-Fi network.
Open Control Point on your iPhone or iPad. On Face ID models, swipe down from the top right corner, on Home models, swipe up from the bottom edge. Find the Repeat icon (two rectangles).
From the list of available devices, select your Xiaomi TV. If the TV requests a code, it will appear on the screen and it will need to be entered on the iPhone. Once successfully paired, the smartphone screen will be transcribed to the TV. To stop the broadcast, click on the icon again and select Stop Repeat.
| Parameter | Miracast (Android) | AirPlay (iOS) | Google Cast |
|---|---|---|---|
| Type of connection | Wi-Fi Direct / Router | Router (required) | Router (required) |
| Delay. | Medium | Low. | Low. |
| Quality. | Depends on the signal. | High (up to 4K) | High. |
| Screen locking | Screen's on. | You can turn it off (for video) | You can turn it off (for video) |
Using the Google Home app for broadcasting
An alternative and often more stable way is to use Google Cast technology (Chromecast built-in). Xiaomi TVs have built-in support for this standard. To work, you will need the Google Home app, which can be downloaded from the Play Market.
Install the app and log in to your Google account. It will automatically find devices on your network. Select your TV from the list. In the control menu that opens, click Cast my screen. This method often works more stable than native Miracast, especially for streaming videos from apps.
Many apps, like YouTube, Netflix, or Kinopoisk, have their own broadcast button (a wave rectangle icon), and if you click on it, you tell the TV to play the video directly from the Internet, which will unload the smartphone and save its battery, in which case the phone acts only as a remote control.
⚠️ Attention: When streaming via Google Cast, the video quality depends on the speed of your internet connection, as the data stream goes directly to the TV, bypassing the smartphone.
What to do if the TV is not visible on Google Home?
Solving common problems and errors
Despite the simplicity of the technology, users often face problems, the most common being “Device not found,” which almost always means that devices are on different networks (for example, one is connected to Guest’s guest network and the other to the main one), or use the 5 GHz band on one device and 2.4 GHz band on another without the router’s support for proper routing.
The second problem is the desynchronization of sound and image, or the constant buffering, which indicates a weak Wi-Fi signal. Try moving the router closer to the TV or using a Wi-Fi repeater, and it's worth checking if someone on your network is using torrents or online games to clog the channel.
If there is an image but no sound, check the audio settings in the app itself or in the settings of the TV (Settings → Sound → Output). Sometimes it helps to simply turn off and turn on the HDMI-CEC function in the settings of the TV.
- 🔄 Reboot your router, TV, and smartphone – it solves 80% of problems.
- 📶 Check if the router is enabled mode “Customer isolation” AP» (AP Isolation).
- 📲 Remove the Wireless Monitor app on TV and install it again from the store.
- 🛡️ Turn it off. VPN on a smartphone, as it can block local device detection.
💡
Miracast connection stability is 90% dependent on the quality of your Wi-Fi router and the absence of interference in the air.
