Modern smartphones, especially models from the brand Huawei, have enormous amounts of memory and are capable of recording video in 4K resolution. However, viewing such content on a small screen is often not entirely enjoyable. Many users are looking for a way to display an image on a large TV screen, and the most affordable method seems to be using a regular USB cable, which is always at hand.
Unlike wired technologies like HDMI or wireless protocols like Miracast, connecting via USB interface has its own unique features and limitations. A standard USB port on a TV is most often designed for reading files from flash drives, rather than real-time screen mirroring. Understanding this difference is critical before starting setup in order to avoid the disappointment of the phone screen not being mirrored on the TV.
Nevertheless, there are effective scenarios for using such a connection. You can view your media library, photos and videos directly from the device’s memory using the TV’s built-in media player. In this material, we will look in detail at how to set up the connection, what operating modes are supported Android on Huawei devices and how to get around typical compatibility problems.
Technical limitations and operating modes of USB
First of all, it is necessary to understand the fundamental difference between data transmission and video transmission. When you connect your smartphone Huawei and your TV with a cable, you are establishing a file sharing connection. The TV sees the phone as an external drive, similar to a regular flash drive or hard drive.
Direct broadcast of the desktop image (screencasting) via a standard A-to-C USB cable is technically impossible without the use of special adapters that support video output. A regular USB 2.0 or 3.0 port on a TV cannot receive a video stream using the protocol that mobile processors use to display images.
However, this does not mean that the connection is useless. You get access to all files stored in the internal memory or on the memory card microSD. This is ideal for watching downloaded movies, family photo archives, or listening to high-quality music through the TV's speaker system.
⚠️ Warning: Do not try to use cheap data-only charging cables. They physically do not have internal contacts for transmitting information, and the TV simply will not see the connected device.
There are several connection protocols that the phone can offer after connection. The most common mode is MTP (Media Transfer Protocol), which allows the TV media player to scan the phone's file system. Less commonly used is the PTP (Picture Transfer Protocol) mode, which is focused solely on transferring photos, which can be useful for older TV models.
Choosing the right cable and checking the ports
The success of the operation depends 90% on the quality of the cable used. The smartphone usually comes with a high-quality cable that supports high data transfer rates and fast charging. It is recommended to use it first. Huawei Usually there is a high-quality wire that supports high data transfer rates and fast charging SuperCharge. It is recommended to use it first.
Pay attention to the connectors. Most TVs have USB Type A ports (a standard rectangular connector), while modern Huawei phones use a connector USB Type-C. You will need a USB Type-C to USB Type-A cable. If you still have the original cable from the charger, it is most likely suitable.
It is also important to check the version of the port on the TV. The blue color inside the connector usually indicates the USB 3.0 standard, which provides faster file reading speeds, which is critical for playing heavy 4K video files. Black or white color indicates the presence of a USB 2.0 port.
- 🔌 Use only certified cables that support data transfer, not just charging.
- 📺 Connect the cable to the USB 3.0 port (blue) for comfortable viewing of high-definition video.
- 📱 Make sure that the connector The Type-C on the phone is clean and not clogged with dust, which can disrupt contact.
If the cable is damaged, pinched or has visible insulation defects, the connection may be unstable. The TV may constantly lose the device or not respond to the connection at all. In such cases, replacing the cable often solves the problem instantly.
Step-by-step guide for connecting Huawei to TV
The process of establishing a connection is intuitive, but requires a certain sequence of actions to correctly identify the device by the TV media player. First, you need to physically connect the devices.
Insert one end of the cable into the USB port on the TV, and the other into the charging port of your smartphone. Huawei. Typically, a USB connection notification will appear on your phone screen within a few seconds. By default, the system may select the "Charge Only" mode, which will not allow the TV to see files.
You need to change this setting. Swipe down from the top of the screen to open the notification panel and look for the "USB Charging" or "USB Settings" message. Click on it to open the mode selection menu.
☑️ Connection algorithm
In the menu that opens, select Transferring files or MTP. It is this mode that makes the phone’s file system readable by external devices. After selecting the mode, the TV should make the characteristic sound of connecting a new device.
Now take the TV remote control. Press the button Input, Source or the square with arrow icon to open the signal source selection menu. In the list of available inputs, find your USB port (for example, USB 1 or HDD) and select it.
The file manager or TV media player will start. It will begin scanning the connected drive. This process may take from a few seconds to a minute depending on the number of files on your smartphone.
⚠️ Attention: The signal source selection menu interface may differ on TVs of different brands (Samsung, LG, Sony). If the automatic window does not appear, look for the “Input” button on the remote control manually.
Setting up file access and navigation
After the TV has detected the phone, you will see the folder structure. In the environment Android files are usually distributed across directories. To search for photos and videos, you will need folders DCIM, Pictures, Download or Movies.
Folder DCIM is a standard storage for all pictures taken with your phone camera, as well as videos. If you used third-party applications to download content, the files may be located in the Download folder or in specific application directories.
Navigation is carried out using the TV remote control buttons. Use the arrows to navigate through the file system and the OK or Enter button to open folders and run files. Some TVs allow you to sort files by date, name or type.
| Content type | Standard Android folder | TV support |
|---|---|---|
| Photos | DCIM / Camera | JPG, PNG, BMP |
| Video | DCIM / Movies / Download | MP4, MKV, AVI |
| Music | Music | MP3, FLAC, AAC |
| Documents | Download / Documents | PDF (rarely) |
If the TV does not see certain files, check their format. Built-in players often have a limited set of supported codecs. For example, video in format HEVC (H.265) may not be played on older TV models without installing additional codecs, which cannot be done via USB.
Why do some videos not play?
Built-in TV players often do not support modern audio codecs (for example, DTS or AC3) or complex containers. If there is video, but no sound, the problem is the incompatibility of the audio track. In this case, converting the file on your computer before recording it to your phone will help.
Alternative methods: Huawei Share and wireless transfer
If your goal is to broadcast the screen or watch videos in maximum quality without being tied to a cable, it is worth considering the technology Huawei Share. This feature allows you to create a direct wireless connection between your phone and a compatible TV or media player.
For Huawei Share to work, both devices must support this technology or be on the same Wi-Fi network. You may need to install a special receiver application on your TV if the function is not built into the firmware by the manufacturer.
Activate the function in the menu Settings → Device connections → Huawei Share. Turn on the switch and wait until the TV appears in the list of available devices on the smartphone screen. This method is often more convenient than cable, as it allows you to control playback directly from your phone.
For maximum stability during wireless transmission, make sure that both your phone and TV are connected to the same Wi-Fi network (preferably 5 GHz) to avoid delays and buffering.
Another option is to use adapters MHL or Slimportif your phone and TV support these standards. These adapters plug into your phone's USB-C port and convert the signal to HDMI, which is then sent to your TV. This is the only way to get honest screen mirroring over a wire.
However, MHL support is becoming less and less common in modern smartphones. Before purchasing an adapter, be sure to check the specifications of your specific model Huawei on the official website so as not to waste money on a useless accessory.
Solving common connection problems
Often users are faced with a situation where the phone is charging, but the TV does not respond to the connection. First of all, check whether the smartphone screen is unlocked. For security reasons, many devices will not transfer data via USB if the device is locked with a password or fingerprint.
It is also worth checking the USB debugging settings, although this is usually not required for MTP mode. Go to Settings → System → For developers and make sure that USB debugging is turned off unless you are doing professional debugging, as this can sometimes conflict with the standard file transfer mode.
If the TV sees folders, but they are empty, the files may be rights-protected or located in the system area hidden from external devices. Try moving the media files to the root directory or a clearly visible folder Download.
⚠️ Warning: If your TV freezes when you try to open a heavy video file from your phone, the USB cable's reading speed may not be fast enough for a high-bitrate data stream. Try using a better cable or USB 3.0 port.
In rare cases, the problem lies in the file system. Android uses a file system that some older TVs may not read correctly. Rebooting both devices often helps clear caching errors and establish a clean connection.
If the TV does not see the phone, in 80% of cases the problem is solved by selecting the correct “File Transfer” mode in the smartphone notification or by replacing the cable with a known good one.
