Modern Xiaomi Mi TVs and Mi Box consoles offer impressive multimedia capabilities, but often users do not know how to bring an image from a smartphone to a large screen without unnecessary cables. The wireless projection feature, also known as Miracast or Translation, is built into the Android TV shell and allows you to instantly duplicate the screen of a mobile device, this is especially convenient for viewing photos, videos from a gallery or showing presentations in the office.
However, the configuration process may vary depending on the operating system version and the regional features of the firmware. In some cases, the system does not see the device automatically, requiring manual intervention through the developer menu or third-party applications. In this article, we will discuss all the nuances of connection, including hidden settings and solving common connection errors.
First of all, make sure your TV and smartphone are connected to the same Wi-Fi network. This is a fundamental requirement for the stable operation of the DLNA and Miracast protocols. If the router is sending out a signal at 2.4 GHz and 5 GHz, try to keep both devices in the same frequency range to minimize latency.
Preparation of equipment and network
The first step in setting up wireless projection is to properly prepare the network environment. Xiaomi TVs with a PatchWall shell or a pure Android TV require a stable connection to transmit a high-resolution video stream. If the network is overloaded, you will encounter image artifacts and sound desynchronization.
Check the connection status in the TV menu. To do this, go to Settings → Network and Internet and make sure that the connection status is active. It is also worth rebooting the router if it works without interruptions for a long time, as this often solves problems with the visibility of devices on the local network.
- 📡 Make sure that both devices (TV and smartphone) are connected to the same router, not to the guest network or mobile Internet.
- 🔄 Restart your router and TV to update IP-Addresses and resets the cache of network services.
- 🛡️ Check your router’s antivirus or firewall settings that can block ports required for the Miracast protocol.
⚠️ Attention: Using Guest Network (WIFI) often isolates devices from each other, making wireless projection impossible.
It's important to note that the speed of wireless projection is directly dependent on the quality of the signal. If the TV is far from the router, use a Wi-Fi repeater or connect the TV to the router via a router. LAN-cable, if the model of the TV Xiaomi Mi TV portable.
Activation of the function on the TV side
On most Xiaomi TVs, the signal reception feature is enabled by default, but sometimes it needs to be activated manually or run the corresponding application.The interface can be called Wireless Monitor, Translation or Wireless Display.
To search for the feature, use voice search on the remote or go to the app section. If the built-in app is not found, you can install it from the Google Play Store by searching for "Wireless Display" or "Miracast".
When the app is launched, the TV will have a waiting window on the screen, and that's when the TV goes into detection mode and becomes visible to external devices, and don't close that window until the pairing is complete.
☑️ Checking the TV's readiness
Note that on some PatchWall firmware, the menu may be hidden in the depth of the settings. Try pressing the menu button on the remote and selecting Translation or Screen Mirroring in the drop-down quick action list.
Setting up a smartphone to broadcast the screen
The process of enabling projection on a smartphone depends on the device manufacturer and the version of the Android operating system. In Xiaomi smartphones with a MIUI shell or HyperOS, this feature is called “Translation” and is located in the notification curtain or in the Connect and Sharing menu.
Users of other brands, such as Samsung, Huawei or OnePlus, should look for the "Smart View," "Projection" or "Screen Translation" features. The action algorithm is the same for everyone: run a device search and select your Xiaomi Mi TV from the list.
If the search doesn’t work, try updating the available device page, and make sure that your smartphone has Wi-Fi and Bluetooth modules enabled, as they are used for the initial handshake of the devices.
What to do if your phone can’t see TV?
Once the connection is successful, a request for permission may appear on the smartphone screen, confirm the action, and the image from the mobile device will appear on the TV, and the image quality can be adjusted in the broadcast settings, choosing between priority quality or smoothness.
Use of embedded apps and Chromecast
Instead of full screen duplication, it’s often more convenient to use the built-in Chromecast feature, which is supported by most video streaming apps like YouTube, Netflix or VK Video, which allows you to stream content directly from the Internet servers without overloading your smartphone’s processor.
To use the Chromecast, open the video on your smartphone, click on the broadcast icon (a rectangle with waves) and select your Xiaomi TV. Unlike Miracast, here the phone acts only as a remote control, and you can freely switch to other tasks or lock the screen.
If the built-in feature doesn't work, make sure that the Google Home app is installed and updated, and that's the one responsible for the discovery protocol that allows you to find Chromecast devices on the network.
| Method | Quality. | Impact on the battery | Better for you. |
|---|---|---|---|
| Miracast (Translation) | Depends on the signal. | High (screen on fire) | Photos, games, browser |
| Chromecast | Stable HD/4K | Low (background) | Video, music |
| HDMI cable | Maximum. | Charging is coming. | Presentations, games |
Using Chromecast often solves the problem of audio and video desynchronization that occurs when wirelessly projecting the entire screen, especially when viewing heavy content in 4K.
Solving Connection and Delay Problems
The most common problem when using wireless projection on Xiaomi Mi TV is image delay (lag) or intermittent connection breaks.This is often due to Wi-Fi ether congestion, especially in apartment buildings.
To minimize delays, try switching the router to a less loaded channel or using the 5GHz band, which provides a higher data rate but has a smaller range.
⚠️ Note: If you play dynamic games with a latency of more than 100 ms, wireless projection may not be suitable. In such cases, use wired connection or Game mode in your TV settings.
It’s also worth checking if you’re running on background traffic-consuming processes, such as update downloads or cloud synchronization of photos, and channel release often stabilizes the image.
💡
To reduce latency when streaming games on your Xiaomi phone, turn on Game Mode and select Network Priority in its settings or turn off background downloads for other apps.
In some cases, resetting the network settings on the TV helps. Go to Settings → Network → Reset network settings, then re-enter the Wi-Fi password. This will clear old configurations that may conflict with the new connection.
Alternative methods and third-party applications
If standard Android TV tools don’t work or support the desired format, you can use third-party apps. A popular solution is to install the AirScreen or ApowerMirror app directly on the TV via the Google Play Store.
These programs emulate various data protocols, including AirPlay for Apple devices and enhanced versions of Miracast. Once you install the application, follow the on-screen instructions to pair.
Another option is the use of DLNA-Players such as LocalCast or BubbleUPnP. They allow you to stream media files from phone to TV without duplicating the entire screen, which saves battery life.
💡
Installing a specialized receiver application on a TV often solves compatibility problems that cannot be eliminated by standard system tools.
Remember that using third-party software may require a subscription to remove ads or unlock Full HD quality, however, the basic functionality is usually available for free.
