Many smart tech users are wondering how to connect a laptop to a Xiaomi TV via Bluetooth, believing that this protocol allows you to broadcast an image. Indeed, the presence of a Bluetooth module in modern Smart TVs opens up wide opportunities for peripheral management, but its functionality is often misunderstood. Unlike HDMI or Wi-Fi Direct, this interface was originally designed to transmit small data, rather than streaming high-resolution video.
Owners of Xiaomi Mi TV and Mi Box devices often try to find the Bluetooth Image Receiving option in their settings, but they face its lack. This is not a system error, but a technical limitation of the standard. However, this wireless module is not worth ignoring - it is ideal for transmitting audio streams, connecting keyboards, mice and gamepads, turning your TV into a multimedia center.
In this article, we will take a closer look at the real-world possibilities of Bluetooth connectivity between a laptop and a TV, explain why it won’t work, and suggest effective alternatives, learn how to configure high-quality audio output via wireless headphones or a TV-connected speaker, and use a laptop as a remote control.
Bluetooth Technical Limitations for Video Transmission
The first thing to realize when trying to configure a connection is the bandwidth of the channel. Bluetooth has a significantly lower data rate than Wi-Fi or wired interfaces. Even the most advanced versions of the standard are not able to provide stable video streaming in 1920×1080 or 4K resolution without significant delays and artifacts.
Xiaomi TVs that run on Android TV or its own PatchWall shell use the Bluetooth module primarily for control and audio. When you see your laptop on the list of available devices, the system suggests using it as a source of sound or input, but not as a display. Trying to trick the system and transmit a video signal through this channel is technically impossible without specialized codecs that are not supported at the level of the TV OS.
⚠️ Note: There are no standard drivers or hidden settings in MIUI for TV, So, the software that promises this is most often malware, and it's the software that would allow you to broadcast your desktop exclusively via Bluetooth.
The main purpose of this interface in the context of multimedia is to create a personal network for accessories. If your goal is to display an image, you will have to turn to other technologies, which we will discuss below. However, in the case of audio, Bluetooth does a great job, providing sufficient quality for most use cases.
Real-life Bluetooth use cases with a laptop
While video cannot be transmitted, connecting your laptop to a Xiaomi Smart TV via Bluetooth offers a number of useful features, most notably, the organization of a wireless audio system, where you can run a movie on a laptop and output the sound to your home theater or soundbar connected to your TV if it supports relay, or directly to Bluetooth headphones coupled to your TV.
The second important scenario is to use a laptop as a remote control, and although Wi-Fi is more common, some models allow you to emulate a keyboard and mouse, which is especially useful when typing in a YouTube search bar or navigating menus when a standard remote seems too slow.
- 🎧 Wireless sound: Connecting a laptop as an audio source for external speakers paired with a TV.
- 🖱️ Cursor control: Using a laptop touchpad to move the cursor on a TV screen (requires third-party software).
- 🎮 Gaming: Connecting a gamepad to a laptop that, via a Bluetooth network, can indirectly affect games launched on TV (in rare cases).
It’s also worth noting that you can use Bluetooth to debug applications if you’re a developer. ADB over Bluetooth (although it’s rare and requires a lot of customization) can transfer small data packets or control commands, but for the average user, it’s redundant.
💡
For a stable Bluetooth connection, make sure that the wireless module drivers on your laptop are updated to the latest version, which reduces delays in audio transmission.
Instructions: Combining laptop and TV Xiaomi
If you decide to use Bluetooth for audio or control, you need to do the pairing procedure correctly. The process begins with activating the visibility mode on your Xiaomi TV. Without this step, the laptop simply won't detect the device in range.
On the TV remote, click the setting button (cog icon) and go to Settings → Remotes and Accessories → Add Accessory. At which point the TV goes into search mode. On your laptop, open Bluetooth settings through the taskbar or Start menu.
☑️ Pre-conjugation check
The list of available devices on your computer should show the name of your TV, such as Mi TV 4S or Android TV. Click on it and confirm the pairing code if it appears on the screen. After a successful connection, the system can suggest choosing the type of device - select Headphones or Audio Drive if you plan to transmit audio.
| Action. | On Xiaomi TV | On a laptop (Windows 10/11) |
|---|---|---|
| Activation | Settings → Remote and accessories | Settings → Devices → Bluetooth |
| 2. Search. | Select "Add Accessory" | Add Bluetooth button |
| 3. The conjugation | Waiting for the request | Selection of the TV name from the list |
| 4. Confirmation | Press OK on the screen. | Press "Connect" |
It's important to understand that successful pairing doesn't guarantee automatic audio transmission. You may need to manually switch the audio output device on Windows. To do this, click on the speaker icon in the tray and select your TV from the list of playback devices.
Why the image transfer does not work
Many users mistakenly believe that if devices are connected, the image should be broadcast automatically. This is the misconception stems from confusion between different wireless protocols. Bluetooth and Wi-Fi Direct (Miracast) are different technologies with different purposes.
Bluetooth bandwidth even in version 5.0 is limited to about 2-3 Mbps in real use, whereas streaming FullHD video requires a stable 15-25 Mbps. Xiaomi TVs simply do not have a software decoder that would collect video stream from Bluetooth packets in real time.
⚠️ Warning: Attempts to install special “transmitter” applications from unverified sources can lead to virus infection of the TV or disruption of Android system services TV.
Also, the TV operating system doesn't treat the incoming Bluetooth connection from the PC as a video signal. It waits for HID (Human Interface Device) commands to control or the A2DP audio stream. Video drivers just don't know what to do with that data, even if it were miraculously transmitted.

Alternative ways to connect a laptop to Xiaomi TV
Since you can't output a picture via Bluetooth, you should consider working methods. The best and most stable option is cable connection via HDMI port. Just connect the laptop and TV with a cable, switch the signal source to the TV to the appropriate input (for example, HDMI 1), and the image will appear instantly.
If wires are not possible, the best wireless solution is Miracast technology (called Connection or Projection in Windows). Xiaomi TVs support this standard out of the box. You don't need additional applications, just press the Win + K keyboard.
- 📡 Miracast: Wireless image transfer in high quality without delay (with good Wi-Fi).
- 🌐 Google Chrome Cast: Chrome browser’s built-in feature lets you stream a tab or entire screen to your TV.
- 🔌 HDMI cable: Quality guaranteed 4K HDR flattened.
You can also use the Xiaomi Projector app or the built-in Translation feature in the TV's Quick Access menu, which uses a local Wi-Fi network that is far faster than Bluetooth.
💡
Always use HDMI or Miracast for video and gaming. Bluetooth is reserved for headphones and controllers.
Sound tuning: Bluetooth as an audio bridge
So back to what Bluetooth does really well, which is transmit audio, and if you want to listen to a movie from a laptop on a powerful speaker system connected to a TV, or vice versa, to bring audio from TV to Bluetooth headphones connected to a laptop (although that's more complicated), you need to set your priorities right.
On Windows, go to Control Panel → Sound → Playback. Find your Xiaomi TV device in the list. If it's "Disabled," right-click and select "Enable." Then set it to the default device.
There may also be settings on the TV side. Go to Settings → Sound → Sound output and make sure the right source is chosen. Sometimes, after a PatchWall firmware update, the settings can be reset, and the sound goes again through the TV speakers, ignoring the Bluetooth connection.
The sound quality depends on the codec used. Xiaomi TVs usually support SBC and AAC codecs. For normal movie watching and listening to music, this is quite enough. However, for professional audio or low latency games, Bluetooth may not be suitable due to the desynchronization of audio and video.
⚠️ Note: When using Bluetooth headphones with a TV, audio delays up to 200 ms are possible. For movies, this is compensated by the player settings, but in games it can be noticeable.
Solving Connection Problems
Even if all instructions are followed, users may encounter difficulties, often not seeing the TV or the connection is constantly broken, this can be due to interference on the air, especially if microwave ovens or other Wi-Fi routers are nearby at 2.4 GHz.
The first solution is to reboot the modules. Turn off Bluetooth on both devices, wait 10 seconds and turn it on again. If that doesn't work, try removing the device from the saved list ("Forget the device") and pairing it again from scratch.
The problem can also be in laptop drivers: Go to Device Manager, find your Bluetooth adapter and check for updates. For Xiaomi TVs, it is useful to clear the Bluetooth cache in the developer menu (if activated) or reset the network settings.
