Modern Xiaomi smartphones have computing power comparable to budget laptops, but the display diagonal often limits the possibilities of productive work or comfortable multimedia consumption. Users are increasingly wondering how to display an image on an external monitor or TV, turning a mobile device into a full-fledged media center. The functionality of the shell MIUI (HyperOS) allows you to implement the scenario of using the second screen quite flexibly, providing several connectivity options.
The implementation of the output of the image depends on the hardware of your gadget, in particular on the presence of the video output in the USB Type-C port. While flagship models support the transmission of digital signal directly, budget and mid-budget segments may require the use of software solutions or wireless protocols. Understanding the technical limitations of a particular device is the first step to successful implementation of the task.
In this guide, we will discuss in detail all the available ways to connect an external display to Xiaomi smartphones. We will look at hardware methods using adapters, software interface settings, as well as the nuances of wireless signal transmission. The correct configuration will allow you not only to duplicate the picture, but also to create a full workspace.
Hardware requirements and compatibility check
Before you purchase cables or adapters, you need to make sure your smartphone is technically capable of transmitting video through a charging port. Not all USB Type-C connectors are the same: budget models often feature USB 2.0 ports that only transmit data and current, but do not support video output. Direct image transfer requires support for DisplayPort Alt Mode or MHL technology.
You can check for video output support by looking at the specifications of your model’s processor and power controller on the manufacturer’s official website. Flagship series such as the Xiaomi 13, 14 Ultra or Mi 11 tend to have full video output. At the same time, the popular Redmi Note series often lack this feature at the hardware level, making it impossible to connect via a simple cable-adapter.
⚠️ Note: Trying to use cheap adapters USB-C on HDMI on devices without hardware support of the video output can lead to overheating of the power controller and failure of the charging port.
If direct connectivity is not possible, don't despair. There are alternative methods that use software to encode a video stream and transmit it over Wi-Fi or via USB debugging, although they can introduce a slight delay. For heavy tasks like games, it is preferable to use models with native HDMI support.
Connection via USB-C adapter to HDMI
The most stable and high-quality way to display an image is to use a special adapter. If your device supports DisplayPort Alt Mode, you will need a cable or dock with an HDMI connector, which allows you to transfer images in high resolution, up to 4K, without noticeable delays.
The connection process is extremely simple and does not require the installation of additional software. The smartphone automatically recognizes the connection of the external display and switches the video output. In some cases, you may need to activate the mode in the settings, but most often the system responds instantly.
☑️ Connection check HDMI
After the cables are physically connected, Android will suggest you choose to work mode, you can duplicate the screen of your smartphone or use the extended mode if it is supported by the running application, for watching videos or presentations, this is the ideal solution for maximum clarity of the picture.
It is important to use high-quality cables that can pass enough data. Cheap analogues often work unstable, causing flickering or periodic loss of signal. It is also worth considering that when you are actively transmitting video, the battery can run out faster, so docking stations with an additional power port will be very useful.
Configure wireless image output (Miracast)
If the wires are inconvenient or the device port does not support video output, wireless technology comes to the rescue.The Miracast protocol, built into the MIUI shell, allows you to broadcast the contents of the screen to any compatible TV or console located on the same Wi-Fi network. This feature is often called "Translation" or "Wireless Monitor".
To activate the function, you need to lower the notification curtain and find the Translation icon. If it's not on the visible panel, click on a pencil or three dots to edit the Quick Access menu and add this element, and after activation, you will start searching for available devices within the network range.
The list of available receivers can vary depending on the signal quality and router settings. Make sure your Smart TV or console (such as an Android Box or Apple TV with AirPlay/Miracast support) is enabled and ready to pair. Some TVs require you to pre-start the Screen Share or Miracast app.
⚠️ Note: Input lag is possible when transmitting images wirelessly, making this method unsuitable for dynamic games that require instantaneous response.
What to do if the TV is not on?
The quality of the picture when wirelessly connected depends on the speed and stability of the Wi-Fi connection. To view video in high resolution, it is recommended to use a 5 GHz network, which provides more bandwidth. In conditions of severe interference, the image can artefact or slow down.
Using Xiaomi’s desktop mode
Some Xiaomi models, especially tablet computers and top-end smartphones, support a special desktop mode when connected to an external display, which transforms the familiar look of Android into a desktop operating system with a window mode and taskbar.
Activation of the mode usually occurs automatically when a monitor is detected, but may require manual inclusion in the Settings menu. → Additional functions → Desktop mode: This allows you to use your smartphone as a system unit by connecting your keyboard and mouse to it via Bluetooth or USB-hub.
In this mode, app windows can scale to the size of a monitor, rather than just stretching like on a smartphone. This significantly improves the ergonomics of working with documents, spreadsheets and a browser.
However, not all applications are optimized for horizontal and large screens, and some programs can open in a small window in the center or be forced to unfold to the full screen, ignoring the proportions of the monitor.
💡
For comfortable work in desktop mode, connect external peripherals through OTG-Hub: this will turn the smartphone into a full-fledged replacement for PCs for office tasks.
Broadcasting through receiver applications
In cases where the built-in system tools do not work or the TV does not support Miracast, you can use third-party applications. Popular solutions such as Google Home, AirScreen or specialized utilities for Smart TVs allow you to organize the reception of the signal on the TV side.
The principle of such programs is to install a client application on a smartphone and a server application on a TV (if it is Android TV) or use the built-in Chromecast functions. Google Home, for example, allows you to broadcast the Chrome browser tab or the entire screen of the device to Chromecast-enabled TVs.
To adjust, you need:
- ⚡ Install the Google Home app on Xiaomi smartphone.
- ⚡ Launch the application and find your device in the list available.
- ⚡ Press the button "Cast screen" (Cast screen).
- ⚡ Confirm permission to record the screen in the Android system window.
This method is universal and works on almost any device where you can install the appropriate software, but it puts additional strain on the smartphone processor, since the video is coded in real time, which can lead to heating of the case.
Comparison of connection methods and characteristics
The best way to connect depends on your goals: whether you want maximum performance in games, comfortable text work or just watching movies. Below is a comparison table to help determine the method.
| Method | Image quality | Delay (Latency) | Stability | Requirements |
|---|---|---|---|---|
| USB-C on HDMI | High (up to 4K) | Minimum | Tall. | Support for DP Alt Mode |
| Miracast (Integrated) | Medium/High | Medium | Depends on Wi-Fi. | Smart TV / The console |
| Google Home (Chromecast) | Average. | Tall. | Medium | App, Wi-Fi. |
| Desktop mode | Depends on the cable. | Minimum | Tall. | Flagship models |
As you can see from the table, wired connectivity is the best choice for quality and responsiveness; wireless methods benefit from convenience and lack of extra wires, but lose in connection stability; Wi-Fi is also good for presentations or viewing photos, but for games it is better to use cable.
⚠️ Warning: During long-term operation in the broadcast mode of the screen, the smartphone can become very hot. It is recommended to remove the protective case for better heat sink or use external cooling.
Solving Connection Problems
Even if all instructions are followed, users may encounter difficulties, such as a black screen, no sound, or intermittent connection breaks, often due to incompatibility of screen resolutions or outdated drivers.
If there is an image but no sound, check the audio output settings in the Settings menu. → Sound and vibration → Sound output. The system can by default continue to output sound through the smartphone speaker, ignoring the TV. HDMI or Bluetooth device.
In case the screen goes out after a while, check the power saving settings. The power saving mode can limit background activity and screen brightness, which affects broadcast stability. It is also worth upgrading the smartphone firmware to the latest version, as manufacturers often release patches that improve compatibility with external displays.
💡
The key to a successful connection is understanding the limitations of your device: if a USB-C port doesn’t support video, no cables will help, and wireless broadcasting will be the only way out.
