Connecting a smartphone Xiaomi to a TV via USB cable seems like a simple task, but in practice users are faced with a lot of nuances: from the TV not responding to the connection to data transfer errors. Unlike wireless technologies like Miracast or Google Cast, a USB connection promises stability and minimal delays - but only if both devices are configured correctly.

Many people mistakenly believe that it is enough to insert the cable into the ports and the image from the phone will immediately appear on the screen. In fact, it USB connection between Android and TV works differently: it is intended primarily for transferring files, rather than mirroring the screen. However, with the help of additional settings and applications, you can even organize video broadcasting or control your phone from the TV remote control. In this article we will analyze all working scenarios - from basic data exchange to advanced functions.

⚠️ Important: connection capabilities depend on the TV model Xiaomi (series Mi TV A2, P1, Q2 etc.) and version MIUI on a smartphone. Some functions may be limited on budget TV models with reduced firmware.

1. What USB cables and adapters are suitable for connection

Not every cable is capable of transferring data between a phone and a TV. For stable operation you need USB-C (Type-C) to USB-A with support USB 2.0/3.0 and a data transfer function (not just charging). Here are the key requirements:

  • 🔌 For modern Xiaomi (Redmi Note 11/12, POCO X5 and newer): cable USB-C — USB-A labeled SS (SuperSpeed) for speeds up to 5 Gbps. Budget cables without shielding may cause errors when transferring large files.
  • 📺 For Xiaomi TVs: port USB 3.0 (blue connector) is preferable - it provides high speed and compatibility with the mode MTP.
  • ⚡ Adapters: if the TV only has HDMI, you will need an adapter USB-C to HDMI with support DisplayPort Alt Mode (for example, Baseus or Anker). Regular "passive" adapters will not transmit the image!
  • 🔄 Double-sided cables: Avoid cheap models with non-standard pinouts - they can damage the phone port.

💡 Tip: If the cable comes with the phone, check it on another device (for example, a PC). Often, “native” cables Xiaomi are optimized only for charging.

2. Basic phone setup: enabling data transfer mode

By default, when connected to a TV, the smartphone Xiaomi will only charge. To activate data exchange, follow the steps:

  1. Connect the phone to the TV with a cable. A notification will appear on the smartphone screen "Charging via USB".
  2. Touch the notification and select "Transfer files" (MTP) or "Transfer images" (PTP).
  3. If the notification does not appear, open Settings → Connected devices → USB and select the mode manually.

⚠️ Attention: on some firmware MIUI 14 the option MTP may be hidden. In this case:

  1. Activate Developer mode (click on Version MIUI 7 times in Settings → About phone).
  2. Go back to Settings → Advanced → For developers and enable "Debugging by USB".
  3. Connect the cable again - the option MTP should appear.

On Xiaomi Mi TV 4S/5X series TVs, MTP mode may not be supported due to firmware limitations. In this case, use alternative methods (see section 5).

3. Setting up a Xiaomi TV to work with USB devices

TVs Xiaomi based on Android TV or Google TV require separate settings to recognize connected devices. The instructions are relevant for models Mi TV Q1E, P1E, A2 43" etc.:

  • 🔧 Go to Settings → Devices and accessories → USB.
  • 📁 Select "Use as storage" (for MTPmode) or "Camera" (for PTP).
  • 🔄 If the phone is not displayed, restart the TV by holding the power button on the remote control for 5 seconds.
  • 🛠️ On older models (before 2020), you may need to manually update the firmware via Settings → About TV → System update.

📌 Feature: TVs Xiaomi with PatchWall (Indian firmware) can block the connection of uncertified devices. In this case:

  1. Open Settings → Privacy → Special Permissions.
  2. Find the item "Unknown sources" and allow installation from USB.
What to do if TV does not see phone?

1. Check the cable on another device (PC, laptop). 2. Try another USB port on the TV (if available). 3. Disable the "Charging optimization" function on the phone in the battery settings. 4. Reset the USB settings on the phone: Settings → System → Reset settings → Reset USB settings.

4. Transferring files between your phone and TV

After successful connection in the MTP mode, you will be able to view your phone files directly on the TV. The control interface depends on the model:

Action Mi TV on Android TV Mi TV on PatchWall
Access files Open the application "Files" → "USB drive" Go in "My Content" → "USB"
Copying files Select files → "Copy" → select a folder on TV Press Menu on the remote control → "Copy"
Play video Open the file via "Gallery" or "Video Player" Use the built-in "Media Player"
File formats Supported MP4, MKV, JPG, MP3 Limitations on AVI, FLAC (conversion required)

⚠️ Attention: TVs Xiaomi do not support direct recording to USB drives in format NTFSIf necessary. copy files with a volume of >4 GB, format the flash drive to exFAT via your phone (Settings → Storage → Format as internal drive).

💡 Useful advice: to speed up the transfer of large files (for example, movies c 4K) connect the phone to USB 3.0 (blue port) on the TV and use a cable with support USB 3.1 Gen1.

5. How to duplicate the phone screen to the TV via USB (alternative methods)

The standard USB connection does not transmit the image from the smartphone screen - this requires additional tools. Let's consider the working options:

Method 1: Application ApowerMirror + OTG adapter

If your TV supports installing applications (models on Android TV),:

  1. Download ApowerMirror to your phone and TV via Google Play.
  2. Connect your phone to TV via USB-OTG adapter (for example, USB-C to USB-A).
  3. Launch the application on both devices and select "USB connection".

📌 Limitation: image delay ~1-2 seconds, sound is transmitted only through the phone.

Method 2: Mode DeX (for Xiaomi flagships)

Models Xiaomi 12 Pro, 13 Ultra and MIX Fold support mode DeX (analog Samsung DeX), which converts TV into a desktop:

  1. Connect the phone to TV via USB-C to HDMI adapter (with support DP Alt Mode).
  2. Enable the mode in the notification shade: swipe down → "DeX".
  3. Use the TV remote as a mouse (control the cursor via DPAD).

💡

For stable operation of DeX, disable the energy saving mode on your phone: Settings → Battery → Performance mode.

Method 3: Scrcpy for advanced users

Free utility Scrcpy allows you to duplicate the screen Android to TV via USB with minimal latency. You will need:

  • 🖥️ Computer with Windows/Linux (as an intermediate link).
  • 🔧 Enabled USB debugging on the phone.
  • 📺 Connecting TV to PC via HDMI or Miracast.

Command to run (enter in the PC terminal):

scrcpy --bit-rate 8M --max-fps 30

⚠️ Attention: on TVs Xiaomi with a processor Amlogic (series Mi TV 4A) may experience stuttering due to poor graphics performance. In this case, reduce the bitrate to 4M.

6. Solving common problems

If the phone is not detected by the TV or files are not transferred, check the following points:

Problem Cause Solution
TV does not see the phone Incompatible cable or port Use original cable Xiaomi or certified USB 3.0
Error "Device not recognized" Protocol failure MTP Reboot both devices, select mode PTP instead MTP
Files are copied slowly USB 2.0 or fragmented memory Connect to USB 3.0 (blue port) and defragment the phone storage
Video does not play Unsupported codec Convert the file to H.264 using VLC or HandBrake

🔧 Port diagnostics: if none of the cables work, check the TV's USB port for physical damage. Connect a flash drive to it - if it is not detected, the port is faulty.

💡

90% of connection problems are solved by replacing the cable with a certified one (with the USB-IF logo) or resetting the USB settings on the phone.

7. Security: how to protect data when connecting

Connecting the phone to the TV via USB allows access to file system, which creates risks of data leakage. Follow the rules:

  • 🔒 Disable auto-connection: in the developer settings (Settings → For developers) disable "Allow USB debugging when connected".
  • 📂 Hidden folders: move confidential files to a folder with a dot at the beginning of the name (for example, .private) - they will not be displayed on TV.
  • 🛡️ Encryption: enable encryption of the phone in Settings → Security → Encryption (will slow down the operation, but will protect the data).
  • 🚫 Prohibition of installation: disable in TV settings "Installation from unknown sources" for USB.

⚠️ Attention: on TVs Xiaomi with firmware for China (CN ROM) may be absent encrypting the USB connection. In this case, use PTP instead of MTP —it transfers only media files, without access to system folders.

8. Alternatives to USB: when is it better to use wireless technologies

USB connection is convenient for transferring files, but for screen mirroring or video streaming, it is better to consider alternatives:

  • 📶 Miracast (Wi-Fi Direct): supported by all Mi TV since 2018 Latency ~0.5 sec, but requires stable Wi-Fi.
  • 🖥️ Google Cast: works through the app Google Home. Supports 1080p, but not 4K.
  • 🔗 DLNA: to transfer media files without screen duplication. Use the application BubbleUPnP.
  • ⚡ HDMI adapter: for models with USB-C and support DisplayPort (for example, Xiaomi 13 Pro).

📊 Comparison of technologies:

| Technology | Latency | Max. resolution | Internet required | Compatible with Xiaomi TV |

|------------------|----------|------------------|--------------------|---------------------------|

| USB (MTP/PTP) | Net | Fayly | Net | Da (ogranichenno) |

| Miracast | 0.3–0.8 s| 1080p | Net | Da |

| Google Cast | 0.5–1.2 s| 1080p | Da | Da |

| HDMI-adapter | Net | 4K | No | Yes (only for flagships) |

💡

USB is not suitable for games and videos in high resolution (>1080p) - use an HDMI adapter or Miracast.
