Direct transmission of video from the phone to the TV exclusively through USB-Cable for screen mirroring purposes is not possible in most standard scenarios.

USB-The interface is primarily designed to transfer files, charge or connect peripherals, rather than transmitting a video signal in real time as it does. HDMI. However, there are workarounds and specific use cases. USB-drives that allow you to achieve the desired result. In this article, we will discuss in detail how to use USB-linking to view content, and consider more efficient wireless alternatives, which are often confused with wired connection due to the similarity of the end result.

Modern Android TVs, such as Xiaomi Mi TV and Redmi TV, have a powerful operating system that allows you to flexibly manage the source of the signal. Data protocols allow you to use the phone as a store of information that the TV can read. Understanding this architecture will help you avoid the frustration of a broken cable and choose the right method of integrating devices into your home network.

Technical limitations USB-broadcast

Before you start physical device connection, you need to understand the architecture of the interaction between your smartphone and your TV. When you connect your phone and TV with a USB-to-USB cable, the Android operating system on your TV sees the connected device as an external drive, similar to a flash card or hard drive, which means that direct video streaming (Screen Mirroring) through this cable will not happen, because it requires other standards, such as MHL or DisplayPort Alt Mode, which are rarely implemented in a bundleage of a smartphone-to-TV directly without adapters.

The main function of USB in this context is file sharing. You can copy a movie to a phone, cable it to a TV, and the TV box recognizes the phone's memory as an external medium.

It is also important to consider the version USB-Xiaomi models are often equipped with ports. USB 2.0 and USB 3.0. for transferring heavy video files in high resolution 4K It is preferable to use blue ports denoting the standard. USB 3.0, as they provide faster data read speeds. Using a slow port can lead to slowing down of the video or failure to play the file.

Preparation of equipment and compatibility check

To make a reliable connection, you'll need to make sure that all the components of your system are ready to go. First, check for quality cable. If you plan to use your phone as a storage device, any serviceable cable that can transmit data, not just charge the device, will do. For owners of flagship smartphones with a Type-C port, it is important that the cable maintains the appropriate speed standards.

The second step is to check the file system format. Xiaomi Android TVs work best with either NTFS or FAT32 file system. If your phone is not detected by the TV when connecting over USB, it may be that the device uses a proprietary file transfer protocol (such as MTP in Charge Only mode), which the TV cannot process correctly without additional software.

• 📱 Smartphone with serviceable USB-port and enabled debugging or file transfer mode.
• 🔌 Cable USB (preferably original or certified, not more than 1.5 meters long for stability).
• 📺 Xiaomi TV with a working port USB and installed Android system TV.

Alternative: Broadcasting Online Content via DLNA and Wi-Fi

Since the request often implies the desire to watch movies “from the Internet” (online), rather than downloaded in advance, the method of filmmaking is not limited to the following: USB-And this is where wireless data technologies come into play, which are integrated into the Xiaomi ecosystem. DLNA (Digital Living Network Alliance allows you to stream media from phone to TV over a local Wi-Fi network.

To implement this method, both devices must be connected to the same Wi-Fi network. You do not need any cables. Open a video file on your phone (local or online via a supported player) and click the Translate button (the icon of the rectangle with waves). From the list of devices, select your Xiaomi TV. The TV will pick up the stream and start playing using its own Internet channel or buffering data from the phone.
