Smart TV owners often face the need to play media content that is not available through standard streaming applications. Whether it is a family archive of photos, high-resolution movies or presentation documents, all this requires an effective way to transfer data from a mobile device or computer to a large screen. Xiaomi TVs with Android TV operating system provide ample opportunities for local file sharing, but not all methods are obvious to the average user.
There are many ways to do this, from simple USB flash drives to advanced network protocols. The choice of the specific method depends on the size of the data being transferred, the speed of your router and the availability of the necessary cables at hand. In this article, we will discuss in detail how to transfer a file to Xiaomi TV using wired and wireless technologies, so you can choose the most convenient option.
It's important to understand that the built-in memory of a TV is not designed to store large amounts of information permanently, so most methods involve either direct playback from an external medium or streaming. 4K HDR It is recommended to use wired network through the local network LAN-Connection, because Wi-Fi may not provide stable bandwidth. Let's look at the tools available.
Use of the USB-← Storage: The Classic Method
The easiest and most reliable way to upload content to the screen is to use it. USB-flash drives or external hard drives. Xiaomi Mi TVs TV ported USB 2.0 or 3.0 that file systems can use FAT32 and NTFS. If your file weighs more than 4GB, make sure the drive is formatted in NTFS, Otherwise, the system may not see the file or refuse to copy it.
Once you connect the drive to the port on the back or side of the TV, the system will automatically start the scan. You need to go to the main menu and find the Media Player or Mi Video app. USB-The folder structure will be displayed as a tree, making it easy to find the file you want.
It’s worth noting that the built-in player may not support some specific codecs or subtitles formats, so it’s wise to install a third-party player, such as a VLC for Android or MX Player, through the Google Play store on your TV, which have their own codecs and often handle “heavy” files better than the standard tools.
💡
If the TV doesn’t see the file system NTFS, Try to reconnect the flash drive to another USB-port, preferably blue (USB 3.0) as they are often better compatible with external HDD.
But there's a limitation to this method: it doesn't allow files to be airborne from a phone without a physical medium, and networking is better suited to fast-paced sharing.
Transfer via Mi TV Assistant and Wi-Fi
Xiaomi’s ecosystem offers a native wireless file transfer solution that doesn’t require you to install additional software on your TV if you’re using Android or iOS smartphones. The Mi TV Assistant app (or the built-in File Transfer feature in your TV settings) creates a local server that’s available to all devices on a single Wi-Fi network.
To get started, make sure your smartphone and TV are connected to the same router. On the TV, go to the settings menu and find Settings. → On TV. → Status or special application Mi TV Assistant will be listed. IP-address and port, and QR-code.
- 📱 Open your browser on your smartphone and enter the address displayed on the TV screen, or scan. QR-code.
- 🔐 Confirm the connection on the TV screen by pressing “Accept” or entering a pin code.
- 📂 Use the interface in your phone’s browser to upload photos, videos or APK-files directly in the memory of the TV.
This method is convenient because files are stored in the device’s internal memory, which allows you to install applications (APKs) or edit documents. However, the transfer speed is limited by the bandwidth of your Wi-Fi channel. When transferring large amounts of data (more than 10 GB), the process can take considerable time.
Screen broadcast and Miracast protocol
If your goal is not to save a file on your TV, but to simply show its contents on a large screen, the ideal solution is to stream an image. Miracast technology (often called “Transaction” or “Wireless Monitor” in Xiaomi devices) allows you to duplicate the screen of a smartphone or laptop on the TV in real time.
To activate the feature on your Xiaomi TV, go to the signal source menu and select Wireless Display. On your Android smartphone, open the notification curtain and find the Broadcast or Smart View button. After searching for devices, select your TV from the list.
⚠️ Note: When using Miracast to view high-resolution video, there may be delays or desynchronization of sound, as the video stream is encoded and transmitted in real time (DLNA or USB).
This method is also great for displaying presentations or web pages, and the quality of the image depends on the Wi-Fi signal. If you notice artifacts or "quaking" videos, try to get closer to the router or switch to 5 GHz.
Organization of DLNA server for multimedia
Protocol DLNA (The Digital Living Network Alliance is a de facto standard for home media networks that allows the TV to see and play files stored on a computer or a computer. NAS-It saves space in Xiaomi's internal memory without copying them. TV It allows you to switch between movies instantly.
On a Windows computer, you can activate Media Streaming in network settings. On macOS or Linux, you can use server programs like Universal Media Server or Plex. Once you set up the server on your TV, your computer will appear in the Network app in the player app.
The advantage of DLNA is that it supports metadata: movie posters, episode descriptions, and album covers are automatically uploaded, creating a beautiful library, but if the computer is turned off or goes into sleep mode, access to the files will be lost.

Comparison of data transmission methods
To make it easier for you to navigate your connection patterns, we've created a comparison table that will help you quickly determine which method is best for your particular situation, whether it's an urgent photo transfer or watching a heavy-duty video. 4K-film.
| Method | Speed. | Convenience | Best application |
|---|---|---|---|
| USB drive | Tall. | Medium (physical access required) | 4K movies, APK installation, large archives |
| Mi TV Assistant | Medium | High (no wires) | Photos, video from the phone, small files |
| DLNA / SMB | Depends on the network. | High (automation) | Viewing media library from PC/NAS |
| Miracast | Low/Mediocre | High (instantly) | Screen demonstration, browser, social networks |
As you can see from the table, there is no one-size-fits-all solution. For one-time operations with large files, USB remains the king of speed and stability. For everyday use and sharing photos from leisure, Wi-Fi transmission via Mi Assistant is ideal.
Solving format problems
A common problem for users is when a file is successfully transferred but the TV refuses to play it, due to the limitations of the built-in decoder. MKV, AVI or HEVC/H.265 codecs may require additional resources or support that is not available in the stock player.
In such cases, you shouldn’t try to convert video on your computer, spending time. It is much more effective to install a third-party player on your Xiaomi TV. The leader in this area is VLC Media Player, which is “omnivorous” and supports almost any containers and audio tracks, including AC3 and DTS.
⚠️ Note: If you play the video through DLNA or USB no sound, the problem is almost certainly in the audio format (e.g, DTS). Installation VLC or MX Player solves this problem 99% of the time.
Why can't the TV see the files on the flash drive?
It’s also worth checking the bitrate of the video. If the file has a bitrate above 100 Mbps, even USB 2.0 may not be able to handle the data stream, causing friezes, in which case only switching to USB 3.0 or using network methods with a gigabit connection will help.
Final recommendations for optimization
To ensure maximum data transfer speed over Wi-Fi, it is recommended to use routers with support for 802.11ac (Wi-Fi 5) or later, operating in the 5 GHz band. The 2.4 GHz frequency is often overloaded by neighboring networks, which leads to a drop in speed and connection breaks when transferring files.
Clean the cache of your TV’s host apps and players regularly. The accumulated debris can slow down the interface and index new files, and you can do this through the Settings menu → Apps → Application Management.
💡
The optimal bundle for home theater based on Xiaomi TV — it DLNA on-site server for movies and USB-flash drive for installing applications and rare files of large volumes.
Using cloud storage, such as Google Drive or Yandex.Disk, is also possible through a browser on your TV, but this is the least convenient way due to the need for authorization and restrictions on downloading large files in web versions of interfaces.
