Xiaomi’s current smartphones have powerful multimedia capabilities to display images from the screen to large displays on TVs or monitors, a feature that is becoming indispensable when showing presentations, watching high-resolution movies, or running demanding mobile games. Users often look for ways to activate this option, as the standard settings layout can vary depending on the version of the MIUI or HyperOS shell.
The connection process, known as broadcasting or wireless display, is based on Wi-Fi Direct and Miracast, which ensures that video streams are transmitted with minimal delays. You don't need to lay additional cables to get started, just a stable wireless connection between devices. It's important to understand that the quality of the image is directly dependent on the speed of your local network and the power of the router.
In this article, we will take a look at all available methods of displaying images, including built-in system tools, third-party applications and specific settings for Redmi and POCO models. You will learn how to fix common connection problems and why sometimes the TV does not see the phone.
Built-in wireless broadcast function in MIUI
The MIUI shell provides users with a native screen duplication tool that is hidden in the option menu, a method that is preferred because it does not require third-party software installation and is optimized by the company's engineers to work with Snapdragon and MediaTek chipsets. Activation takes only a few seconds if you know where to look for the right option.
To start the process, you need to open the standard Settings app and go to Connect and Share. Here you should find the Translation item (in some versions of the firmware it may be called Wireless Display or Cast). Once you turn on this feature, the phone will automatically search for available devices within the range of your network.
If you don't find the right item in the settings menu, try the search bar at the top of the screen, type in the word "Translation" or "Cast" and the system will suggest you move to the desired switch, which is especially true for newer versions of HyperOS, where the menu structure has been significantly redesigned.
- 📱 Open the notification curtain and find the Translation icon for quick access.
- 📺 Make sure the TV is activated (Screen Mirroring).
- 📶 Check that both devices are connected to the same Wi-Fi network (2.4 GHz or 5 GHz).
- 🔄 Restart your router if the list of available devices is left blank.
⚠️ Note: When using the built-in broadcast, the smartphone screen may go out to save energy, but the sound and video will continue to be transmitted to the TV.
☑️ Checking before connection
Using Google Chromecast technology
Most modern TVs and media consoles support the Google Cast protocol, which is integrated directly into the Android operating system. Unlike Miracast, which duplicates the entire screen, Chromecast allows you to stream content from specific applications such as YouTube, Netflix or VK Video, freeing up the smartphone for other tasks.
To take advantage of this opportunity, make sure your Xiaomi has Google Play services installed. Open the app you want to show you content and find the characteristic wave rectangle icon in the corner. Click on it and you'll see a list of available devices. Selecting your target TV will instantly trigger the video playback on the big screen.
The advantage of this method is the ability to control playback from the phone: you can pause, change the volume or flip through the tape without interrupting the display on the TV. In addition, the quality of the picture is often higher, since the TV downloads the stream directly from the Internet, rather than through the phone.
There are also aggregator apps like Google Home that allow you to stream the entire screen of your smartphone to Chromecast built-in devices, opening the app, selecting your TV, and clicking on the Translate screen button, which is ideal if the built-in MIUI function is non-stable.
- 🎥 Ideal for streaming services and online cinemas.
- 🔋 Significantly less consumes battery power smartphone compared to full duplication.
- 🌐 It works even with a weak Wi-Fi signal, since the phone does not encode the video stream.
- 📱 Allows you to use other apps on your phone while browsing.

Specific configuration for Redmi and POCO models
Xiaomi’s sub-brands, Redmi and POCO, often use slightly modified versions of the shell, where some features can be renamed or moved, and owners of these devices should pay attention to the Security or Tools app, which often hosts system utilities.
In some POCO firmware, the stream function is either in a separate application called “Mi Share” or integrated into the control center. If standard search doesn’t work, try pinching the Wi-Fi icon in the notification curtain — the advanced wireless settings sometimes hide the “Translation” switch.
The Redmi Note series’ budget models are less powerful, which can lead to micro-latency when transmitting high-resolution images, and in such cases, it is recommended to reduce the quality of the output image in the broadcast settings or switch to the 2.4 GHz frequency, which has a longer range, albeit lower speed.
Special attention should be paid to the Mi Drop feature (therein part of Mi Share), which allows you to transfer files quickly, but is not designed for streaming the screen. Do not confuse these concepts, as trying to run a video stream through the file exchanger will only lead to a connection error.
💡
On POCO devices, try activating Developer Mode and enabling the option to Enable Wireless Debugging, which sometimes helps the system see older TV models.
Third-party applications for screen duplication
If Xiaomi’s regular funds can’t cope with the task or your TV belongs to the old generation without Smart TV support, specialized applications from the Google Play Market will come to the rescue. They use their own compression and data transfer algorithms, which often allows you to connect even devices that are incompatible at first glance.
One of the most popular solutions is the Web Video Caster app, which allows you to stream video files stored in your phone's memory or stream video from your browser directly to your TV. The app automatically converts the video format to on-the-fly, ensuring compatibility with DLNA and Chromecast receivers.
ApowerMirror or TeamViewer QuickSupport has proven to be a great screen duplication application, requiring the installation of the client part on the TV (if it is an Android TV) or the use of the built-in browser of the TV to receive the signal. Such programs often offer additional functions, such as controlling the phone from the remote or recording the screen.
It is worth considering that free versions of such applications often contain advertising or have session time limits, and they can create additional load on the processor, causing the smartphone to heat up during prolonged use.
| Annex | Type of transmission | Do I need a TV client? | Delay. |
|---|---|---|---|
| Web Video Caster | Video/Photo | No (DLNA/Chromecast) | Low. |
| ApowerMirror | Full screen | Yes (for Android TV) | Medium |
| TeamViewer | Remote access | Yes. | Tall. |
| BubbleUPnP | Media files | No. | Minimum |
Connection via USB and HDMI cables
For users who want maximum image quality without compression and delay, wired connectivity remains the optimal solution. Xiaomi smartphones with a USB Type-C port that supports the USB 3.1 standard or higher can transmit video directly through the Type-C to HDMI adapter.
It is important to understand that not all phone models support video output via the charging port.The flagship Xiaomi Mi series, Xiaomi 11/12/13/14 Pro and some POCO F models are equipped with the necessary controller. Budget devices are most often deprived of this capability, and the adapter will not work.
When you connect the cable, the phone will automatically go into the output mode. In some cases, you will need to manually select the source of the signal on the TV (for example, HDMI 1). The image can scale automatically, but sometimes you will have to ajustar resolution in the settings of the smartphone screen.
This method also allows you to charge your phone while in use if the adapter has an additional power port, which is critical for gaming or watching long movies, as the screen is the main energy consumer.
- 🔌 A high-quality Type-C adapter is required HDMI video-enabled.
- ⚡ Provides the transmission of the image in 4K compressed and artifactless.
- 🎮 Ideal for gamers due to lack of input delay (input lag).
- 🔋 Allows you to charge the device at the same time (if there is a power port on the adapter).
⚠️ Note: Cheap cables for the switch 200-300 The RUB often only works on charging and transferring data, ignoring the video signal.
💡
Wired connectivity is the only way to get a 4K 60Hz picture without loss of quality, but it requires the compatibility of your smartphone’s USB-C port.
Solving Connection Problems
Despite the simplicity of the technology, users often face situations where the phone can't see the TV or the connection is constantly broken. The most common reason is the settings of the router, which isolates devices from each other (AP Isolation).
Another common problem is using different frequency bands. If a phone is connected to a 5GHz network and the TV only works at 2.4GHz, they may not see each other even if the network names are the same. In modern routers, this problem is solved by the Smart Connect feature, which combines the bands into one network.
Antivirus programs or aggressive MIUI power saving settings can block the background of broadcast services. Try adding the Translation or Mi Cast app to the battery exclusion list, allowing them background activity.
If nothing works, reset your network settings on your smartphone, which will return your Wi-Fi and Bluetooth settings to factory values by removing saved passwords, but often eliminates software conflicts that interfere with the connection.
