Xiaomi screen broadcast: how to display the image on the monitor or PC

Modern Xiaomi smartphones have powerful processors and high-quality displays, but watching movies, presentations or games often requires a larger screen. Output from your phone to a computer monitor or TV is a solvable task, but requires an understanding of the available interfaces and software constraints. The MIUI and HyperOS ecosystem offers several built-in tools that allow you to implement wired and wireless connectivity without installing third-party software.

In this article, we will discuss in detail the technical nuances of connecting via a USB Type-C port, the features of video transmission protocols and software methods for broadcasting over a local network. You will learn why not all cables are equally useful and how to turn a regular monitor into a smart display for your gadget.

Hardware requirements and port compatibility

The first and most critical step is to test the technical ability of your smartphone to transmit video through the charging connector. Not all USB Type-C ports in Xiaomi devices support the DisplayPort Alt Mode standard, which is necessary for direct transmission of video stream to an external display. Budget models often have USB 2.0 ports that do not physically have channels for video transfer, limited to only charging and data transfer.

Flagship and mid-budget devices, such as the latest generation Xiaomi 13, 14 or Redmi Note series, are most often equipped with a USB 3.0 or 3.1 port that supports video output. To connect, you will need a special adapter (hub) or USB-C to HDMI cable. It is important to understand that a regular charging cable, even if it looks the same on both sides, may not work for broadcasting an image.

If your computer monitor doesn't have HDMI input, but only VGA or DVI, you'll need an active converter, because the digital signal from your phone needs to be converted to analog or other digital format, and the image quality in this case may depend on the throughput of the converter.

Wired connection via USB-C and HDMI

The most stable way to display an image is to use a physical connection. This provides minimal latency, which is critical for gaming, and does not depend on the speed of the Wi-Fi router. To implement this method, you will need an adapter, often called the Type-C adapter on HDMI. Once the cable is connected to the smartphone and monitor, the Android system must automatically determine the external display.

In some cases, the image may not appear immediately, you need to manually switch the signal source on the monitor, pressing the Input or Source button and selecting the appropriate port. HDMI. Xiaomi smartphone usually offers to choose the mode of operation USB-Connections: Charge only, File Transfer or Translation. To operate the screen, select the broadcast mode or allow access if the appropriate system window appears.

If the image went but you didn't like the quality, check the resolution settings. From the Settings menu → Connected Devices → Cast (or similar in your firmware version), you can adjust the output settings. Some hubs require external power, so if the picture disappears or the phone is quickly discharged, connect the charger to an additional USB port on the adapter.

Wireless streaming via Wi-Fi and Chromecast

When wires are inconvenient, wireless technology comes to the rescue, and Xiaomi’s Cast, which is based on Miracast and Google Cast, requires both the phone and the receiving device (a TV with a Smart TV or a PC with a receiver installed) to be on the same local Wi-Fi network.

To start broadcasting, lower the notification curtain and find the "Translation" or "Cast" icon. If the icon is not, add it through the button editing menu of the control panel. The phone will start searching for available devices. If your monitor is connected to your computer, you will need to run a special receiver application on your PC, such as the built-in "Projection on this PC" in Windows 10/11 or third-party software like LetsView or ApowerMirror.

The quality of wireless transmission is directly dependent on the stability of the network and the distance to the router. When using the 5 GHz band, the delays are minimal, and the picture is transmitted in high resolution. At 2.4 GHz, twitches and image artifacts are possible, especially when playing video in 4K.

Using the Mi Share app and Xiaomi ecosystem

Xiaomi owners can take advantage of their own ecosystem. Mi Share (or simply Sharing in new versions of HyperOS) not only allows you to transfer files, but also in some scenarios to organize the streaming of content between the brand’s devices. However, the native Cast protocol is more often used to display the screen (screen mirroring) on Xiaomi TV monitors or projectors.

To connect to a smart TV, Xiaomi just needs both devices to be logged in to the same Mi Account, making it easier to find the device and eliminating the need to enter. PIN-The settings of the TV should allow receiving requests for broadcast from unknown devices if automatic detection does not work.

It is worth noting that the functionality may vary depending on the regional version of the firmware (Global, China, EEA). In the Chinese versions of MIUI, the broadcast functions may be more advanced, but require language knowledge or additional regional settings.

To reduce latency in games when wireless broadcast, close the background applications that consume traffic, and if possible, bring the phone closer to the router.

Translation of the screen to the computer through USB-debugging

For advanced users who need to display an image on a computer monitor with minimal latency and the ability to control the phone from the keyboard and mouse, the method of debugging over USB is ideal. This method uses the ADB (Android Debug Bridge) protocol and requires activation of the developer mode on the smartphone.

First, activate Developer Mode: Go to Settings → About Phone and quickly press 7 times on MIUI Version. Then, in the "Additional" → "Development by USB" menu, plug your phone into your PC with a cable and install Scrcpy on your computer, a free, open-source application that streams the screen over USB.

It's run via a command line or shortcut, and the advantage of this method is that it doesn't require root rights, it works very fast, and it allows you to use a computer keyboard to type in text on your phone, which is a great way to show you the interface or work with documents.

⚠️ Attention: When you first connect the cable with debugging enabled, a confirmation request will appear on the phone screen RSA-You need to press "Allow" or the connection will not be established. USB In public places with unknown charging stations.

Comparison of Connection Methods and Problem Solving

The way you connect depends on your goals: speed of response is important for games, stability is important for presentations, and convenience is important for viewing photos. Below is a comparative table of the main characteristics of various methods.

If you encounter a black screen when wired, try lowering the output resolution in your phone’s settings or replacing the cable with a better, HDMI 2.0-enabled standard. Often the problem lies in the lack of power the phone is trying to give to the adapter, so using a hub with additional power input solves most problems.

If you have a wireless connection problem, make sure that the router does not include client isolation (AP Isolation), which prevents devices on the same network from seeing each other, and rebooting the Wi-Fi module on both devices can also help.

⚠️ Note: Some Content Protected Apps (Netflix, Disney)+, Banking applications can block the display of images on external screens due to protection HDCP. In this case, you will see a black image or error message, and it is impossible to get around it without violating the license.

💡

For games and work with text, wired connection through USB-Scripe (Scrcrcryp) or quality HDMI-cable, as they provide minimal input delay.
