Modern Xiaomi smartphone users often face the need to showcase the contents of their device’s screen on a larger monitor or laptop. This may be due to the desire to watch a high-resolution movie, hold a presentation, play a mobile game with better graphics, or just show friends a photo gallery. Fortunately, the Miui ecosystem provides a lot of built-in tools, and third-party developers have created dozens of applications to facilitate this process. The choice of the specific method depends on your goals, the availability of the cable and the requirements for signal delay.
In this article, we will discuss in detail all the current ways to broadcast Xiaomi on the Internet. PC, including standard Windows and Android features, as well as specialized software.We will look at the nuances of configuring wireless connection via Mi Drop and Cast, as well as more stable options using the use of the device. USB-Understanding the technicalities of each method will allow you to avoid lags and desynchronization of sound.
Before you start setting up, make sure both devices are on the same network or have serviceable ports for physical connectivity. To transfer video to 4K without delay, it is critical to use 5GHz Wi-Fi or a quality USB 3.0 cable and higher. A poor-quality connection can lead to image artifacts and interrupt the data stream.
Wireless broadcasting through the built-in function "Translation"
The easiest and fastest way to display an image is to use the native feature of the Android operating system, which in the Miui shell is often called Translation or Caste. This method does not require installing additional software on your computer if you are using Windows 10 or 11, since Miracast technology is built into them by default.
To get started, open the Connection app on your computer (formerly called Projecting to This Computer). In the settings of this app, allow access from any device or only from devices on secure networks. Then on your Xiaomi smartphone, lower the notification curtain and find the Translation icon. If the icon is not, add it through the button editing menu or find it in the Settings application → Connection and Sharing → Translation.
The smartphone will start looking for available devices. When your computer name appears on the list, click on it. A request for permission to connect may appear on the PC screen — confirm it. An image from the phone will instantly appear in the window on the monitor. This method works in both directions: you can control the phone, but the signal delay can vary depending on the quality of the router.
⚠️ Note: When using wireless broadcast via Miracast, the smartphone battery discharges much faster due to the active operation of the Wi-Fi module and processor.
- 📡 Advantages: No cables, fast connection, sound support.
- ⏳ Disadvantages: Possible delay (lag) in games, dependence on the load of the Wi-Fi channel.
- 🔋 Requirements: Both devices must support Miracast/Wi-Fi Direct.
Using the Mi PC Suite app to manage and view
The official software from the manufacturer, known as Mi PC Suite, was historically created for backup and file management, but its functionality allows you to effectively display the screen of the smartphone on the computer. Although support for new models in official versions may be limited, for many Xiaomi and Redmi devices, this remains a stable solution.
To work, you need to download and install the latest version of the Mi PC Suite on your computer, as well as the corresponding application on your phone if your firmware version requires it. Connect your smartphone with a cable to your PC. From the phone menu, select the USB File Transfer (MTP) mode. The program automatically determines the device and prompts you to start the screen mirroring mode.
The main advantage of this method is the ability not only to see the screen, but also to control the smartphone using the mouse and keyboard of the computer, which is especially useful when typing or working with documents. In addition, Mi PC Suite allows you to take screenshots and record video from the screen directly into the memory of the computer without loss of quality.
☑️ Check before connecting Mi PC Suite
It’s worth noting that the program’s interface may seem outdated, but its functional reliability makes up for visual flaws.If the standard version doesn’t see your new device, try to find modified versions from the community that add support for the latest Xiaomi models.
Broadcasting through third-party programs: Scrcpy and Vysor
For users who require minimal latency and high image quality, the ideal solution is specialized utilities such as Scrcpy or Vysor. These programs use ADB (Android Debug Bridge) technology to transmit video streams, which allow you to broadcast a screen with a bit rate of up to 20 Mbps and a frequency of up to 120 frames per second, making them indispensable for gamers and developers.
To use this method, you need to activate the developer mode on your smartphone. To do this, go to Settings → About your phone and quickly click on the build number seven times. Then the "Additional" menu will appear "Developers"; Inside it you need to activate the "Debug by USB" switch.
After connecting the phone to your PC and installing a program (like Scrcpy, which is completely free and open), run an executable file. If the drivers are installed correctly, you will see the phone screen in a separate window. Scrcpy is notable for not requiring the application to be installed on the phone itself and works through the command line or graphical interface, providing virtually zero latency.
Why is Scrcpy better than standard tools?
- 🚀 Speed: Minimum latency, ideal for gaming.
- 🛠 Flexibility: Ability to configure bitrate, resolution and coding parameters.
- 💻 Resources: Low consumption of smartphone processor resources.
⚠️ Note: When first connected through ADB You'll see a request for debugging permission from this computer on your phone screen, and you'll be sure to tick "Always Allow" and press "OK" or you won't get the connection.
Comparison of connection methods: Characteristics table
The best way to broadcast depends on the specific tasks you set for yourself: for video viewing, stable streaming is important, for games, low ping, and for presentations, ease of connection. Below is a comparison table that will help determine the method.
| Method | Delay (Latency) | Image quality | Difficulty setting up | Sound. |
|---|---|---|---|---|
| Miracast (Wi-Fi) | High (100-300 ms) | Good (depends on the network) | Low. | There is. |
| Mi PC Suite | Medium | Average. | Medium | There is. |
| Scrcpy (USB) | Minimum (<40 ms) | Excellent (original) | Tall. | No (requires additional settings) |
| Vysor | Low/Mediocre | Depends on the subscription. | Medium | There is. |
As you can see from the table, wired methods through ADB win in response speed, whereas wireless solutions are more convenient for quick display of content. If you just need to show a photo, there is no point in messing with ADB drivers. However, for streaming games on Twitch or YouTube from a phone via a PC, the wired connection through Scrcpy has no competition.
💡
If you use a laptop with a battery that is dead, a wired USB connection will allow you to simultaneously broadcast the screen and charge the smartphone, saving the charge of both devices.
The solution: Connection and quality issues
Users may encounter a number of typical problems during the setup process. Often, the computer cannot see the phone, or the image is transmitted in jerks. If the PC does not respond to the connection, first check yourself. USB-Many cables that come with cheap accessories are only for charging and have no data lines.
Another common problem is Wi-Fi connection breakage. This can happen if the router is overloaded or the devices are too far apart.Try to switch both devices to a 5GHz band, which is less noisy than 2.4GHz. Also make sure the router doesn't include AP client isolation, which prevents devices on the same network from sharing data.
If you use Scrcpy or Vysor, the image is black or twitching, try lowering the bitrate or resolution in the program settings.
scrcpy --bit-rate 2MThis will reduce the strain on the channel and processor, which often solves the problem of lag on older computers, and it is also worth checking whether the antivirus or Windows firewall blocks incoming connections for broadcast applications.
- 🔌 Cable: Use short cables (up to 1.5 m) for better signal.
- 📶 Network: Disable downloads on other devices during broadcast.
- 🔋 Power Saving: Turn off the phone's power saving mode, it can limit Wi-Fi performance.
Additional features: sound and control
The standard Miracast protocol transmits sound along with video, but in ADB-based utilities (like Scrcpy), sound may not be transmitted by default on older versions of Android (below 11). For Android 11 and above, sound is transmitted automatically. If you have an older version of the system, but you critically need sound from your phone to your PC via USB, you can use a virtual audio cable or bridge applications that broadcast sound through microphone input, although this reduces the quality.
Controlling your phone from a computer opens up new productivity horizons. You can type instant messenger messages from a full keyboard, drag and drop Drag-and-Drop files (in Scrcpy it works out of the box), and run apps. You can also set up hotkeys to emulate Home, Back, and Menu buttons in Miui settings, making navigation even more convenient.
⚠️ Warning: When transferring sensitive information (passwords, banking applications) through third-party programs, remember to be safe. Use only proven open source software or official applications to avoid data leakage.
💡
The optimal link for most users is wireless broadcasting for media and wired (Scrcpy) for work and games.
