How to connect Xiaomi phone to TV via USB

Xiaomi’s modern smartphones have huge screens and powerful multimedia capabilities, but sometimes even a diagonal of 6.7 inches is not enough to comfortably watch movies or presentations. In such situations, a large TV screen comes to the rescue, which can turn a normal evening into a cinema. Many users mistakenly believe that broadcasting an image necessarily requires the Internet, router or complex Wi-Fi Direct setting, but there is a more reliable and stable method – direct wired connection.

Connection through USB-cable provides minimal signal delay and is independent of wireless network speed, which is critical when watching high-resolution video. 4K Unlike wireless protocols, cables ensure that there are no compression artifacts and connection breaks that often occur when a poor Wi-Fi signal is used. In this article, we will discuss in detail all the nuances of physical connection, interface settings. MIUI Possible problems you may face in the process.

It’s important to understand that the result of the connection depends on the type of TV and the version of the Android operating system installed on your gadget. Older TV models may not support modern data protocols, and new smartphones may require special permissions to access the file system. We will look at universal methods that work in most cases, as well as specific settings for owners of Xiaomi and Redmi equipment.

Equipment and cable preparation required

Before you start setting up, you need to make sure that you have the right equipment, as not all cables are the same. The standard charging cord that came with the phone is often only for power transmission and has no internal contacts for data transmission. To successfully connect, you will need a USB Type-C cable with data transmission support, preferably certified and with a length of no more than 2 meters to maintain the signal quality.

If your TV is equipped with a port USB 3.0 (usually blue), it is recommended to use the appropriate cable to achieve maximum data read speed, especially if you plan to broadcast video in high bitrate. OTG-And the quality of the cable directly affects the stability of the connection: cheap analogues can cause periodic shutdowns or a complete lack of response of the TV.

• 🔌 Original or certified cable USB Type-C to USB-A (or USB-C to USB-C, if TV supports).
• 📺 Television with functioning USB-Port and support for multimedia files.
• 📱 Xiaomi smartphone with a serviceable charging connector and a dust-free contact group.
• 🔋 External power (optional) if the TV does not give enough power to the port USB.

⚠️ Warning: Using damaged or too long cables (more than 3 meters) without an active signal amplifier may cause the device to operate unstablely or to have no connection at all.

It is also worth checking the state of the USB-Often, the ports on the front are less powerful and are designed to connect flash drives rather than smartphones. To connect the phone, it is better to use the ports on the back or side, which are often marked as HDD or have a designation of increased current output.

Connection algorithm and choice of mode of operation

Once the hardware is ready, the connection process looks simple, but it contains important nuances in the choice of mode of operation. First connect one end of the cable to the Xiaomi smartphone and the other to the free one. USB-At this point, the phone may display a connection notification, but often the default system selects Charge Only mode, making data transfer impossible.

To change mode, unlock your smartphone screen and lower the notification curtain. Find the USB Charge (or similar) notification and click on it. You will see the USB mode selection menu, where you will select the option of File Transfer (MTP) or Photo Transfer (PTP). This is the key step: without switching to MTP mode, the TV will see the phone only as a power source and will not be able to access the file system.

After the regime's selection MTP The TV screen should run a file manager or media player that will scan the connected device. If the automatic start does not occur, take the TV remote, press the Source or Input button and select the appropriate one. USB-port from the list of signal sources. In some TV models, access to smartphone files is in the Media or Devices section».

It’s worth noting that PTP (Picture Transfer Protocol) mode is less common and is designed mainly for older TV models or specific cameras, but if MTP doesn’t work, it makes sense to try switching to it. In PTP mode, a computer or TV sees the phone as a digital camera, giving access only to folders with images and videos, ignoring the rest of the files.

Set up a TV to work with external devices

Not all TVs are equally friendly to smartphone connectivity, so manual settings may be required. USB-In the settings menu of the TV, often under System or Connections, you can find power management options. USB. Make sure the “AutoStart Media” option is activated so that when you connect your phone, the TV immediately opens the memory contents.

If the TV is equipped with an Android TV operating system, the process may be different from conventional Smart TVs. In this case, the smartphone can be defined as an external storage, and access to files is through an embedded Explorer or third-party applications installed on the TV, for example, X-plore or VLC Player. It is important that the file system on the phone is clear to the TV; modern OS usually use MTP, which emulates work with files regardless of the internal Android file system.

In some cases, the TV may not see folders with system data or applications, displaying only standard media directories: DCIM (camera photos and videos), Download (downloads) and Music. This is the normal behavior of the MTP protocol, which protects the smartphone system from accidental deletion of important files by the user through the TV interface.

Screen broadcasting and multimedia content

USB connection is often confused with screen translation, but technically they are different processes. Direct USB connection in MTP mode provides access to files, but does not broadcast a desktop image in real time. To display an image from the Xiaomi screen to the TV via cable, you need support for MHL (Mobile High-Definition Link) or Slimport technology, which is rare in modern smartphones and requires a special USB-C to HDMI adapter, rather than a simple USB cable.

However, if your goal is to view video files stored in your phone's memory, MTP is the perfect solution: you can run a media player app on your TV, find your smartphone in the sources, and run the video file. In this case, the TV processor decodes the video, which reduces the load on the smartphone battery and allows you to watch the content in maximum quality without loss.

For wireless alternatives, if the cable is not available, Xiaomi owners can use the built-in Cast function, which requires both devices to be on the same Wi-Fi network. If you still need to duplicate the screen through the wire (for example, for games), you will need an adapter. USB-C to HDMI DisplayPort Alt Mode. Put the adapter in your phone, plug it in. HDMI cable from the adapter to the TV, and the image will appear automatically.

• 🎬 To view the video, select files in formats MP4, MKV or AVI for maximum compatibility.
• 🎮 Use an adapter for games USB-C to HDMI with support for 60 Hz and HDCP.
• 📸 Use the mode to show photos PTP, if MTP It causes errors in old TVs.

⚠️ Note: When using adapters HDMI Make sure they are externally powered or connected to a charged phone, as video transmission significantly increases power consumption.

Using USB Debugging Mode for Advanced Users

For those who want to gain full control of the device or broadcast the screen with minimal latency for testing applications, there is a Debugging mode. USB. This method requires you to enable the developer's hidden settings. Go to Settings. → About the phone and quickly press 7 times on the item "Version" MIUI», The message is “You became a developer».

After that, the option "Development by Development" will appear in the menu "Additional" or "Extended settings". USB» When you connect to a computer or specialized equipment on TV (if it supports it) ADB) phone requesting confirmation RSA-This method is rarely used for conventional movie watching, but is indispensable for diagnosing and controlling a phone from a large screen through emulators.

adb connect 192.168.1.XX:5555

If your TV is running Android TV, it's theoretically possible to set up an ADB connection between your phone and your TV over a network or cable, but that requires a deep knowledge of Linux and a network bridge setup. For the average user, this method is redundant, and it's easier to use standard media tools.

💡

If you have enabled USB debugging, don’t leave your phone connected to other people’s charging stations in public places, as this can create a data vulnerability.

Solving common problems and errors

Despite the simplicity of the procedure, users often face a situation where the phone is charging but the files are not visible. The most common reason is choosing the wrong USB mode in the notifications. Check again: the notification should read "File Transfer" rather than "Only Charge." If there is no notification, try changing the cable or cleaning the phone's dust connector with compressed air.

Another common problem is the file system: If the TV is old and does not support a file system that formats the phone’s virtual storage (although this is rare when using MTP), it may not identify the device, in which case try updating the TV’s firmware or using a third-party media player installed on the Smart TV from the app store.

Some older TVs don’t work properly with storage devices larger than 32 or 64 GB. If you have a flagship Xiaomi with 256 GB of memory, the TV can only see partitions or not see the device at all, in such cases using cloud services or creating a separate folder with media on the memory card (if the phone supports SD and the TV reads it through the card reader, bypassing the phone).

⚠️ Warning: Do not remove the cable while actively recording on your phone or updating your system, this may cause file system damage or data loss.
