How to connect a laptop to a Xiaomi TV via Bluetooth

Many users are wondering how to connect a laptop to a Xiaomi TV via bluetooth, wanting to enjoy content on a large screen without unnecessary wires. However, it is important to be clear immediately: Bluetooth technology has significant limitations in transmitting high-resolution multimedia signal. Unlike HDMI or Wi-Fi, this protocol was originally designed to transfer audio and small files, rather than streaming video to 4K.

However, Xiaomi TVs are equipped with wireless communication modules that can be used for certain PC interaction scenarios. You can stream sound from your computer to your TV’s acoustic system or transfer files, but full screen duplication will require additional solutions. In this article, we will discuss in detail the capabilities of Bluetooth connection and alternative methods that will ensure a stable picture.

Modern Smart TVs based on Android TV or PatchWall’s own shell offer flexible settings. Before trying to connect devices, you need to understand what task you want to solve. If your goal is to display a picture of a movie or game, Bluetooth will not be the optimal choice due to the low bandwidth of the channel.

Bluetooth Technical Limitations for Video Transmission

Bluetooth operates in the 2.4 GHz band and has a limited data rate. Standard profiles like A2DP are exclusively for audio streaming. This means that even if you manage to establish a connection between a laptop and a Xiaomi Mi TV, the video signal will not be transmitted.

There are profiles for image transfer, such as OPP (Object Push Profile), but they work on the principle of sending static files, not streaming video. Trying to stream a desktop through this channel will either cause a connection error or transfer individual frames with a huge delay. Bluetooth 5.0 maximum speed is about 2-3 Mbps, whereas FullHD video requires a minimum of 5-10 Mbps stable channel.

So when you're looking for a way to connect your laptop to your Xiaomi TV through bluetooth, you're actually limiting yourself to transmitting sound or files. For video content, Xiaomi engineers, like other manufacturers, are betting on Wi-Fi Direct and wired interfaces. Ignoring that can lead to frustration with the quality of the connection.

💡

Use Bluetooth on a Xiaomi TV primarily to connect wireless headphones, gamepads or external speakers, rather than output an image from a PC.

Preparation of equipment and compatibility check

Before you start any settings, make sure your hardware supports the necessary functions. On the Xiaomi TV side, the Bluetooth module should be active, which is relevant for most modern models of the 4A, 4S, P1 series. The laptop should also have a Bluetooth adapter and current drivers installed.

Check the operating system versions. On a TV, it could be Android TV 9.0 or higher or PatchWall. On a computer, Windows 10/11 or macOS. Outdated software may not support new codecs or pairing profiles, making it impossible to connect.

Also, consider the distance between devices. To ensure stable operation of Bluetooth connections, laptop and TV must be in line of sight, at a distance of no more than 5-8 meters, walls and metal structures can shield the signal, causing communication breaks.

Step-by-step instruction: pairing devices

The connection process starts with activating the visibility mode on the TV, and to do this, go to the main menu and select the settings section. Navigation is done using the remote control.

On the TV screen, consistently perform the following actions:

• 📺 Press the Settings button on the remote or in the interface.
• 🔍 Go to Remote & Accessories or Bluetooth.
• ✅ Select the Add Accessory option to start your search.

Now, to the laptop settings. On Windows, open the settings through Start menu → Settings → Devices → Bluetooth and other devices. Make sure the Bluetooth switch is in the On position.

After scanning, the name of your TV should appear in the list of available devices, for example, MI TV 4A 43 or Android TV. Click on it and confirm the pairing. A confirmation request may appear on the TV screen. PIN-code – make sure the numbers on the laptop and TV screen match, and press Pair).

⚠️ Warning: If the TV doesn’t appear on the list, try restarting the Bluetooth module on both devices or disabling antivirus on your PC, which can block detection.

Transfer audio and files via Bluetooth

Once paired successfully, you can use the channel to transmit sound. This is useful if the laptop's built-in speakers are out of order or you want to get better audio through the TV system. In Windows, right-click on the speaker icon in the tray and select Open audio settings.

From the list of output devices, select your Xiaomi TV. Now all system audio, including audio from browsers and players, will be broadcast to the TV. The sound quality will depend on the SBC or AAC codec supported by both devices.

To transfer files (photos, documents), use the context menu of the file. Right-click, select Send → Bluetooth device and specify the TV. The TV screen will show a request for file acceptance, which must be confirmed by the remote.

Alternative ways to connect a laptop to Xiaomi TV

Since Bluetooth is not designed for video, consider efficient methods of displaying images. The most reliable option is to use an HDMI cable. Connect your laptop to an HDMI connector on the back of your TV. The system automatically detects a new signal source.

If wire use is not desirable, use Miracast technology (in Windows called "Plug"). Both devices must be connected to the same Wi-Fi network. On the remote of the Xiaomi TV, click the button with the image of the Wireless Display application or select the source of the Miracast signal.

On your laptop, press the Win + K key combination. In the list that appears, select your TV. The desktop image will appear on the large screen with minimal latency, allowing you to watch videos and work with documents.

💡

HDMI provides the best quality and no delays, which is critical for gaming and watching movies in high resolution.

Solving Connection Problems

Often users are faced with a situation where the laptop does not see the TV or the connection is constantly broken. One of the common reasons is a crowded Bluetooth cache on the TV. Try to remove old paired devices from the memory of Xiaomi TV through the settings menu.

Another problem is frequency conflict: If your router and Bluetooth adapter are running in congested 2.4 GHz, there may be interference, in which case it is recommended to switch the laptop and TV Wi-Fi network to 5 GHz, leaving Bluetooth to work independently.

Also make sure your TV has USB and ADB debugging enabled if you plan to use third-party streaming apps, which can be found in Settings → About Device → Build (click 7 times).

⚠️ Note: When using third-party applications to broadcast the screen via Bluetooth (emulation), the laptop battery can discharge much faster due to the high load on the coding processor.

Using third-party software to expand functions

For those who still want to try out the non-standard methods, there are emulators trying to use the Bluetooth channel to transmit data, which is then decoded on TV. However, solutions such as BlueSoleil or specialized plugins for VLC often work unstable.

More effective is using remote applications that run over Bluetooth or Wi-Fi. By installing Mi Remote or a laptop app, you can control the TV, but not broadcast the image. This is useful for navigating the menu without looking for a remote.

In a Linux environment, there are command-line utilities that allow you to more flexibly manage your Bluetooth connection, for example, using the bluetoothctl command allows you to manually initiate pairing and trust for devices that the system does not see in the GUI.

sudo bluetoothctl


[bluetooth]# scan on




[bluetooth]# pair XX:XX:XX:XX:XX:XX




[bluetooth]# trust XX:XX:XX:XX:XX:XX




[bluetooth]# connect XX:XX:XX:XX:XX:XX
