The modern multimedia capabilities of Xiaomi Mi TVs allow you to turn the living room into a full-fledged entertainment center, and one of the key features is wireless image broadcast. Miracast technology (often referred to simply as “Translation” or “Wireless Display”) allows you to duplicate the screen of a smartphone, tablet or laptop on a large display without using HDMI cables. This is the ideal way to view photos, videos from the gallery or even show presentations in high resolution. However, despite the simplicity of the concept, the activation and configuration process has its own nuances, depending on the version of the Android TV or PatchWall operating system.
Users often face a situation where the feature is not on the menu or the device simply does not see the TV, which is puzzling. It is important to understand that Miracast is a wireless standard built directly into the Wi-Fi module, so it does not need an active Internet connection to work, although having a single local network makes it much easier to find devices. In this article, we will discuss in detail how to activate signal reception on a Xiaomi TV, what applications may be required for older models and how to ensure stable data transfer without delay.
Before you start setting up, make sure your remote is charged and your TV is working correctly.We'll look at universal methods for most models, including the 4S, 4X, P1 series and newer lines with Google TV. The key to successful synchronization is to support Wi-Fi Direct standard on both devices, which is true for 99% of today's Android and Windows 10/11 gadgets.Let's move from theory to practice and customize your hardware for comfortable use.
What is Miracast and how does it work for Xiaomi?
Miracast is a wireless multimedia content standard developed by the Wi-Fi Alliance. Unlike Chromecast, which requires data to be transmitted via Google’s Internet servers, Miracast creates a direct peer-to-peer connection between the source (smartphone) and the receiver (TV). On Xiaomi Mi TV devices, this feature is often implemented through the Wi-Fi Display system protocol, allowing you to stream the image in real time with minimal latency.
The principle of operation is based on compression of the video stream by the H.264 codec and transfer it over the Wi-Fi channel. This means that the quality of the picture will depend on the signal power and the load of the air. The Android TV operating system installed on Xiaomi TVs has a built-in decoder that instantly unpacks the video stream. It is important to note that the sound is transmitted simultaneously with the video, providing full synchronization, which is critical when watching movies or playing mobile games on the big screen.
⚠️ Note: When using Miracast, the smartphone battery can discharge faster than usual, since the screen of the source device remains active, and the Wi-Fi module operates in high load mode.
For users of the Xiaomi ecosystem, the advantage is the deep integration of the protocol into the PatchWall shell and pure Android. You don't need to buy additional adapters or dongle-s unless you're using a very old TV without Smart features. Understanding exactly how this protocol works will help you diagnose problems faster if the connection suddenly becomes unstable or the sound disappears.
Preparation of equipment and network before connection
The first and most important step is to properly organize the LAN. Although Miracast uses Wi-Fi Direct, many Xiaomi TVs require both devices to be on the same subnet for initial handshake and control. Make sure your router is broadcasting at 2.4GHz or 5GHz, and that the TV is connected to the same network as the mobile device.
Check the software version of your TV. Manufacturers regularly release updates that fix wireless module bugs. Go to the settings menu, select About Device and click System Update. If new versions of Android TV or security patches are available, be sure to install them before you try to set up the broadcast.
☑️ Checking connection readiness
Also worth paying attention to the power saving settings on the smartphone. Aggressive energy saving modes can block the background operation of the Wi-Fi Display service, interrupting the connection immediately after turning off the phone screen. It is recommended to temporarily turn off the Charge Saving mode or add the broadcast app to the exclusion list.
Activation of the broadcast function on the Xiaomi TV
On most modern Xiaomi Mi TV models with Android TV 9.0 and higher, the signal reception function is built into the system and does not require additional applications to be installed. However, it can be hidden in the depth of the menu or require activation through special settings. The standard activation path often follows: click the Settings button on the remote (cog icon), then go to the Applications section or External Logins.
Some versions of the PatchWall shell (localized to Russia and CIS countries) require an app called Translation or Wireless Display. If you can't see it on the home screen, try pressing the menu button (three dots or stripes) on the remote and select "My apps." Launch this app - the TV will go to standby mode, and the device's name will appear on the screen.
For models where the standard app is removed or not working correctly, you may need to install a third-party solution from the Google Play Store.A popular and reliable option is the AirScreen or Receiver for Miracast app. Once you install such an application, launch it, press the Start or Go button, and the TV will broadcast the signal, becoming visible to other devices on the network.
⚠️ Note: If you use a third-party app to receive a signal, make sure it has the necessary permissions to access the microphone and storage, otherwise the audio broadcast may not work.
What to do if the Translation application does not start?
Instructions for connecting an Android smartphone
The process of connecting an Android smartphone may vary slightly depending on the manufacturer and the version of the shell (MIUI, OneUI, ColorOS, etc.), but the overall algorithm of actions remains the same. First, open the quick settings panel by swiping from top to bottom across the screen. Find an icon called Translation, Smart View, Projection, Wireless Monitor or Cast.
Once activated, the phone will start searching for available devices. Your Xiaomi TV (or the name you gave it when you set it up) should appear on the list. Click on it. A confirmation request may appear on the TV screen — use the remote to press OK or Allow. In a few seconds, the image from the phone will appear on the big screen.
- 📱 Samsung: The feature is called Smart View, is in the notification curtain or in the SmartThings app.
- 📱 Xiaomi / Redmi / POCO: The function is called “Cast”, located in the curtain or in the “Settings” menu» → «Connected devices» → «Broadcasting».
- 📱 Huawei/Honor: The feature is called Project, called by swipe with two fingers from the upper right corner or through the control center.
- 📱 Pure Android (Sony, Motorola, Nokia): Look for the “Cast screen” item in the Connected Devices section in the settings.
If your phone offers a choice of live streaming mode, select Mirror screen to duplicate all the display content, including notifications and desktop. If you only want to stream videos from a particular app (like YouTube), use the built-in Cast button inside the app itself, which will provide better picture quality.
💡
To reduce latency when playing through Miracast, turn on the TV “Game mode” in the image settings, if such an option is available in your model.
Broadcasting the screen from a laptop to Windows
Windows 10 and Windows 11 have built-in Miracast support, which makes it easy to display an image on a Xiaomi TV without installing additional software. Make sure the laptop and TV are connected to the same Wi-Fi network. On the laptop keyboard, press the Win + K keyboard. On the right, the Connection panel will open.
The system will start looking for wireless displays. When your Xiaomi Mi TV appears on the list, click on it. The TV screen may have a connection request that needs to be confirmed by the remote control. Once the connection is established, the Windows desktop will be expanded or duplicated to the TV screen.
To fine-tune the transfer quality, you can use projection settings. Press Win + P to select the mode: “Duplicate” (screen copy), “Expand” (second desktop) or “Second screen only” (laptop screen goes out, only TV works). To reduce the mouse cursor delay in Windows 11, you can go to Settings → System → Projection on this PC (although this is for reception, graphics acceleration settings affect the transfer as well).
| Parameter | Description | Recommendation for Xiaomi TV |
|---|---|---|
| Permission | Number of pixels horizontally and vertically | Install 1920x1080 or 3840x2160 (4K) for clarity |
| Frequency of update | Number of frames per second (Hz) | 60 Hz is recommended for smoothness if the signal allows |
| Color format | Color Depth (RGB/YCbCr) | Use RGB for text, YCbCr 4:4:4 for video |
| Coding | Video stream compression method | Automatic selection (usually H.264) |
Graphics card drivers (NVIDIA, AMD, Intel) can also have their own zoom settings. If the picture on the TV is cropped at the edges, look in the graphics card control panel for the option “Scaling” and select “Full screen” or “Save proportions”, removing the zoom on the GPU side for the TV to do.
Solving common problems and errors
Despite standardization of technology, users often face problems: the TV is not visible in the list of devices, the connection is cut off, or there is no sound. One common reason is using a guest Wi-Fi network or splitting the 2.4 and 5 GHz bands on a router without proper setting (AP Isolation).
If the image twitches or is low resolution, try to reduce the load on the Wi-Fi channel, turn off downloads on other devices or switch the router to a less busy channel, and the problem may lie in outdated Wi-Fi drivers on a laptop or an older version of the application on the TV.
- 🚫 Device not found: Check if Bluetooth is enabled on your smartphone (often used for primary search) and reboot your router.
- 🔇 No Sound: In the audio output settings on your phone or PC, select a TV speaker instead of your phone's speakers.
- 📉 Low quality: Close your smartphone to the router or use the 5GHz band, which is less noisy.
- 🔄 Black Screen: Try changing the screen resolution in your phone settings before connecting.
⚠️ Warning: Antivirus programs and firewalls on a Windows computer can block incoming Miracast connections. Try temporarily disabling protection or adding an exception rule for the system.
💡
Miracast connectivity is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, not the power of the TV itself.
