Xiaomi smartphone owners often encounter the acronym “Translation” in the notification curtain or settings menu, not always fully understanding its functionality. In fact, this technology allows you to duplicate the image from your smartphone to an external display, whether it is a modern Smart TV, computer or projector, creating the effect of a wireless multimedia center.
The feature is based on Miracast and DLNA standards, which allows high-definition video transmission without the need for physical cables, which opens up a wide range of possibilities for the user, from watching movies on the big screen to showing presentations or mobile games with friends.
Modern MIUI and HyperOS shells offer advanced synchronization algorithms that minimize signal latency, but for stable operation, it is important to consider not only the software settings, but also the quality of the wireless connection, as well as the compatibility of the receiving device.
The principle of wireless image transmission
The screen broadcast technology on Xiaomi devices is implemented through the Wi-Fi Direct protocol, which allows data to be transmitted directly between gadgets, bypassing the router, although the presence of a shared network often speeds up the detection process.
It is important to understand that the quality of the transmission directly depends on the bandwidth of the channel and the power of the processor. When watching streaming video (for example, YouTube or Netflix), Chromecast technology is often used, when the phone acts only as a remote control, and the content is downloaded by the TV directly from the Internet, which saves battery power.
⚠️ Note: When using full screen duplication (Miracast) smartphone battery discharges much faster due to the high load on the GPU and Wi-Fi module.
The system automatically selects the optimal resolution for an external display. If the TV supports 4K HDR, and the smartphone is able to give such a signal, the picture will be as detailed as possible, otherwise there will be automatic downscale to 1080p or 720p.
💡
To minimize gaming delays, make sure that both your phone and TV are connected to a 5GHz Wi-Fi network, not 2.4GHz.
How to turn on the stream on Xiaomi through the standard menu
Activating the feature in the Xiaomi shell is as simple as possible and does not require the installation of third-party applications. To get started, you need to make sure that both devices are on the same Wi-Fi network, which is a critical condition for their detection.
The connection process is as follows:
- 📱 Open the notification curtain with a swipe from top to bottom and look for the Translation icon (may be called the Wireless Monitor»).
- 📺 Turn on the TV’s signal reception mode (often called Screen Mirroring, Smart View, or Wireless Display).
- 🔍 Wait for the name of your TV to appear in the list of available devices on the smartphone screen.
- 🔗 Click on the device name to establish a secure connection.
Sometimes, the security system can request confirmation on the TV screen. Once successfully paired, the TV screen will show an exact copy of the interface of your smartphone. At the top of the phone screen, a floating control menu will appear, allowing you to curl up the broadcast or change the orientation of the image.
☑️ Checking before connection
Setting up parameters and managing connection
Once connected successfully, users often want to change the display settings, and in the Xiaomi broadcast control menu, you can choose whether the screen is portrait or landscaped, which is especially useful when watching vertical videos from social networks on a horizontal TV.
To fine-tune things like changing resolution or frame rate, you sometimes need access to advanced settings. Go to Settings → Connection & Sharing → Broadcast, and it shows the connection status and the name of your device that other gadgets see.
If you want to stream the sound separately or change its source, use the volume bar. When connecting over Miracast, the sound is usually transmitted along with the video stream, but in some applications (for example, YouTube), the audio stream can go separately through the Google Cast protocol.
| Parameter | Description | Recommended value |
|---|---|---|
| Permission | Quality of the output image | 1920x1080 (Full HD) |
| Frequency of personnel | Smoothness of image movement | 60 Hz (for games) |
| Audio codec | Sound transmission format | AAC or MP3 |
| Delay. | Response time (lag) | < 100 ms |
💡
Optimal settings depend on the content: for movies, resolution is more important, and for games, high frame rates and minimal latency.
Using the Mi Remote application for management
Xiaomi smartphones pre-installed the proprietary Mi Remote app (Mi Remote), which turns the phone into a universal remote control. Although its main function is to manage the IR port, it is also integrated with the smart home ecosystem and can help navigate the Smart TV menu.
If your TV supports MIOT protocol or is a device of Xiaomi ecosystem, you can not only broadcast the screen, but also fully control the interface of the TV, which allows you to flip through menus, run applications and adjust the volume even if the physical remote is lost.
To work through the application, you need:
- 📲 Launch the Mi Remote app on your smartphone.
- 📡 Press the device add button and select the type "TV».
- 📺 Choose your TV brand from the list of suggested.
- ✅ Test the control buttons and save the profile.
It is worth noting that for broadcasting the screen (mirror), the Mi Remote application is rarely used, since the standard "Translation" function in the curtain works faster and more stable.
The Secret Feature of Mi Remote
Broadcasting via Chromecast and third-party apps
Not all TVs support the native Miracast protocol that Xiaomi uses by default, and in such cases, Google Chromecast technology, which is built into many modern TVs and set-top boxes (Android TV, Google TV), comes to the rescue.
To run a Chromecast stream, you don't have to search for the device in the settings menu. Just open the app you want to show content from (YouTube, Netflix, Twitch), and click on the box icon with the waves in the corner. The phone will offer a list of available devices on the network.
If the built-in methods don’t work or the TV is old, you can use third-party solutions. Popular applications like AirScreen or Receiver for Xiaomi installed on a TV (if it’s Android TV) can emulate the signal reception protocol that a smartphone understands.
⚠️ Warning: When using third-party repetitive apps on the TV, increased image latency is possible, making them unsuitable for dynamic games.
There is also the ability to wire-wire via a USB-C to HDMI adapter, the only way to get an image without compression and delay, which is critical for professional graphics demonstration or high-response games.
Solving common problems and errors
Despite the technology, users may encounter difficulties, and the most common problem is “Device not found,” which almost always means that the smartphone and TV are connected to different Wi-Fi networks (for example, one 2.4 GHz network, another 5 GHz network, or guest mode is on).
Another common mistake is desynchronizing audio and video, which can be treated by restarting the router or reducing the broadcast quality in settings if the network is congested, and it's also worth checking if the router is not subject to the AP Isolation restriction, which prevents devices from seeing each other.
If the broadcast is constantly interrupted:
- 📶 Get Closer to the Router to Improve Wi-Fi Signal.
- 🔄 Reboot the Wi-Fi module on your smartphone (turn off/on).
- 📺 Update the TV firmware to the latest version.
- 🔌 Turn it off. VPN on a smartphone, if activated.
In some cases, resetting network settings helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This will delete all saved passwords, but often resolves software driver conflicts.
