Connecting Xiaomi smartphone to TV LG through USB-cable is one of the easiest ways to bring photos, videos or music to the big screen without using complex network settings. USB-The connection allows you to instantly duplicate the screen (translate the image in real time), but the functionality of this port is primarily focused on working with the file system as an external drive. USB TV-wise LG It is possible not always and depends on the specific model and version of the webOS firmware, while access to the media library works stably.
The advantage of a wired connection is the stability of data transfer: you do not depend on the speed of the Wi-Fi router, which may not withstand the flow. 4K-Video and you don't have to worry about sound delays. - Xiaomi in its shell MIUI or HyperOS provides convenient connectivity management tools, but often activates Charge Only by default, which prevents the TV from seeing the contents of the memory. USB, What file formats do you support? LG How to avoid common errors when syncing devices.
It is worth noting an important nuance: if your goal is to play mobile games on the TV or display the desktop, USB-But if you want to use a cable, you might not be able to use it as a universal solution, and you might want to consider Miracast or Chromecast technology, but if you want to watch movies, TV shows or family album photos, you can use a wired connection. USB-Port is the most energy efficient and reliable method, without requiring complex network equipment configuration.
Equipment preparation and cable selection
The first step to a successful connection is to check the physical compatibility of ports. Modern LG TVs are equipped with USB 2.0 or 3.0 ports, which are usually marked "USB IN" or highlighted in color (often blue for version 3.0). Xiaomi smartphones use micro-USB connectors (in older models) or USB Type-C. To connect, you will need a cable that can transmit data, not just the current for charging.
Cheap cables bundled with some low-cost power banks often lack internal data lines. If you plug in such a cable, the phone will start charging, but the LG TV won't see the new device. It's recommended to use the original cable from your Xiaomi kit or a quality certified analog with support for a data standard. The cable length also matters: for confident operation without loss of signal, the length should not exceed 1.5-2 meters.
It's also important to make sure the port on the TV is in good working order. USB-If the flash drive is detected and the content is played, then the port is functioning correctly. LG one of the ports is marked as "USB HDD", It is designed to connect hard drives and can give high voltage, which is safe for a smartphone, but it is better to use standard ports for phones.
⚠️ Warning: Never use damaged cables with inflections or bare insulation.Potency surges from poor contact can damage the power controller on the motherboard of a TV or smartphone.
Setting up USB mode on Xiaomi smartphone
After physically connecting the cable to both devices, the Xiaomi smartphone screen should appear system notification of the new device. USB-By default, the Android operating system selects Charge Only mode for security purposes to prevent unauthorized access to data when connecting to public charging stations. LG This regime needs to be changed.
Lower the notification curtain down and find the message “Charge via USB” (or similar).Click on it to open the mode selection menu. You will need to select the option “File Transfer” (MTP) or “Photo Transfer” (PTP). MTP (Media Transfer Protocol) mode is preferred, as it allows the TV to see the folder structure and all file types, while PTP restricts access to only images.
If the notification doesn't appear automatically, go to your phone's settings. The path may vary slightly depending on the version of MIUI, but it usually looks like this: Settings → Connected Devices → USB. In the Usage USB menu that opens, select File Transfer. After that, a window on the LG TV should pop up about the connection of the new device.
- 📱 Regime. MTP: Full access to the file system, suitable for video, music and documents.
- 📷 Regime. PTP: Emulates a digital camera, convenient only for viewing photos on large screens.
- 🔋 Charging only: Phone charges but data transfer is blocked (default mode).
💡
If the USB mode selection menu is hidden, turn on Developer Mode: go to About Phone and click on MIUI Version 7 times, then in the advanced settings, find the Default USB Configuration option and select MTP.
Instructions for connecting and accessing files
When the mode on the phone is set up, go to the interface of the LG TV. On the remote control, press the Input button (or the icon of the square with the arrow) and select the source of the signal "USB". In newer models with the operating system webOS 4.0 and above, just press the Home button and find the application "Photo and video" or "Mediaplayer" in the lower menu.
The TV system will scan the connected device, which can take anywhere from 5 to 30 seconds depending on the memory capacity of your Xiaomi. If there are too many files, the initial indexing may take longer. Once the scan is completed, the file structure will be displayed on the screen: folders with photos, music and video files.
Use LG's magic remote to navigate through folders. Select the file you want and press OK to play. The TV will automatically launch the built-in player. If the file doesn't open, it's possible that the TV doesn't support that codec or container format, which we'll talk more about in the format compatibility section.
☑️ Connection check
Compatibility of formats and codecs on LG TV
One of the most common problems is when the TV sees the phone but refuses to open video files, which is because LG's built-in media players support a limited set of codecs. Standard formats like MP4 (H.264), AVI, MKV and MOV are usually playable without problems. However, modern Xiaomi smartphones often shoot HEVC (H.265) video to save space that older TV models may not support.
Audio tracks can also be a hindrance. If a video file uses DTS sound (often found in movie rips) and your TV's DTS decoding license has expired or is not available, you'll see a format error message or no sound, in which case the solution is one: using third-party apps or converting the file.
For photos, JPEG, PNG and GIF formats are supported. However, when displaying photos in high resolution (made on modern Xiaomi cameras with a resolution of 48 MP and higher), the TV can process the image for a long time or show it with a delay. This is normal for Smart TV processors, which are weaker than mobile chips.
| File format | Support for LG TV | Recommendations |
|---|---|---|
| MP4 (H.264) | Complete. | The Best Choice for Video |
| MKV (H.265/HEVC) | Partial (depending on the model) | There may be problems with the DTS sound. |
| AVI | Complete. | Old but reliable format |
| FLV / WMV | Not supported | Conversion required |

Alternative ways of transmitting content
If you find wired USB connection uncomfortable because you have to go to your TV to select files, consider wireless alternatives. DLNA technology allows you to stream content directly from Xiaomi Gallery to LG TV if both devices are connected to the same Wi-Fi network. This eliminates wires, but requires a stable router.
To fully duplicate the screen (games, browser, social networks), it is better to use the function "Translation" in the notification curtain Xiaomi. LG TVs support the Miracast protocol, so in the list of available devices you will see the name of your TV. Click on it, and the image from the phone will appear on the screen, the quality of the picture depends on the load of the Wi-Fi channel.
Another option is to use cloud services: by uploading photos or videos to Google Photos or Yandex.Disk on your phone, you can open the corresponding app on your LG TV (if available from the LG Content Store) and access your files without any cables, which is convenient for viewing presentations or slideshows.
- 📡 Miracast: To duplicate the screen in real time without delay (within Wi-Fi).
- 🌐 DLNA: For streaming video and photo from phone memory.
- ☁️ Cloud: To access files without being tied to a specific storage device.
Addressing common problems
Despite the simplicity of the procedure, users often face difficulties, the most common problem is that the TV writes “Unsupported device” or simply ignores the connection, 90% of the time this is solved by re-selecting the MTP mode in the USB settings on the phone or replacing the cable with a better one.
Sometimes the file system of a smartphone is not readable because of errors in the partition table. USB (USB-The modem, the drivers might have stuck. Try rebooting both devices: turn off the TV for 10 seconds, and reboot the phone software.
If the TV sees folders but the inside is empty, check the permissions. On some versions of Android, the first time you connect to the phone, you will see a request "Allow data?" You must click "Allow", otherwise the TV will only see system hidden files that are not of interest to the user.
⚠️ Attention: Do not turn off the cable USB when data is being recorded or files are indexed by the TV, this can cause damage to the file system on the smartphone and data loss.
💡
The stability of a wired USB connection is always higher than wireless, but requires manual selection of file transfer mode on the smartphone each time you connect.
