However, many users face difficulties, as Android TV works differently than desktop operating systems. Simple cable connection does not always guarantee instantaneous appearance of files in the TV interface, requiring the correct configuration of the transmission protocol. In this article, we will discuss all the nuances of physical connection, setting up USB modes and solving common problems.
Unlike wireless broadcasting, wired connection provides a stable data read speed, which is critical for the reproduction of heavy loads. 4K-Direct access to the smartphone file system allows the TV to be used as a reader, allowing access to the gallery, documents and local video archives.

Often the problem lies in a physical data storage medium that can only be designed for charging.
Cables are divided into two main types: charging (2 contacts) and full-fledged data cables (4 or more contacts). To transfer files to Xiaomi Mi TV or Redmi TV, you must use a high-quality cable with support for data transfer standard USB 2.0 or USB 3.0. Visually they may not differ, so it is better to use the original cable from the set of smartphones or a certified accessory.

You should also pay attention to the version. USB-The blue connectors usually indicate the standard. USB 3.0, which provides a higher transfer speed, while black or white – on the other hand, the speed of the transmission is higher. USB For viewing high-definition video, it is recommended to use ports with greater bandwidth, although standard connectors will also be suitable for simple photos.
Setting up USB mode on a smartphone
After the devices are physically connected, the TV may not see the phone unless the smartphone itself has the correct USB mode.

Finding and Opening Files on Xiaomi TV
Once the smartphone is in data mode, you need to refer to the TV interface. In the Android TV operating system, which is installed on most Xiaomi models, external drives are accessed through an integrated file manager or media player. The standard path is usually in the application section.

These players have their own codecs and are able to open almost any file formats that the smartphone broadcasts via USB. After installing, for example, VLC, launch the application and select the side menu section "USB" or "External devices", the player will scan the connected phone and display available media files.

Solutions and Connection Errors
Even if you follow all the instructions, you can have situations where the TV can't see the phone or writes "File is not supported." One of the common reasons is file system formatting. If your smartphone uses an exFAT or NTFS file system and the TV only supports FAT32, the device may not be determined.
In this case, using a third-party player, which often has built-in drivers for NTFS, or flashing the phone (which is not recommended for ordinary users), can also be a problem in the power shortage: if the USB port on the TV produces less than 0.5A, the phone may not start the data mode.

To use this feature, make sure both devices are connected to the same Wi-Fi network. On the TV remote, click the button with the image of the signal source or select the Wireless Monitor app. On a Xiaomi smartphone, open the Control Center and select Translation or Projection, then select your TV from the list.
The advantage of wireless is that you don't have to have any extra wires and you can control content directly from your phone anywhere in the room, but you still prefer wired connections to watch 4K video or high-graphics games, because they ensure that you don't have any delays or compression artifacts.
