Wirelessly transferring content from a laptop to a big screen on Xiaomi TV has become an integral part of the modern multimedia experience, with many users mistakenly believing that it requires Wi-Fi or Wi-Fi. HDMI-But Bluetooth can actually be a reliable bridge between devices, especially when it comes to audio transmission or presentation management. TV Support this method of connecting directly, and the quality of the broadcast depends on the version of the protocol and codecs.
In this article, we will discuss all working methods of broadcasting via Bluetooth β from standard pairing to workarounds using additional adapters and programs. TV (including Mi TV 5 Pro, Redmi Smart TV X and others) support this feature out of the box and where customization is needed, and we will focus on the problem of audio delay when broadcasting video, a key point that is often missed in general instructions.
Before we get into the setup, itβs important to understand that Bluetooth isnβt designed to transmit video streams, but its main application here is audio transmission (for example, to use a TV as a Bluetooth speaker) or control (as a presentation remote).
1 What are Xiaomi models TV Supports Bluetooth broadcasting?
Not all Xiaomi TVs are equipped with a Bluetooth module, and those that do have one often have limited functionality. Here is the current list of Bluetooth-enabled models and their capabilities:
| Model TV set | Bluetooth version | Sound support | Support for video | Notes |
|---|---|---|---|---|
| Mi TV 5 Pro (2020β2023) | 5.0 | Yes. | No (only via Miracast) | Requires software updates to MIUI TV 3.0+ |
| Redmi Smart TV X (2021β2026) | 5.0 | Yes. | Partially (delayed) | It works better with a branded remote. |
| Mi TV Q2 (2022β2026) | 5.2 | Yes. | No. | Supports LDAC high-quality |
| Mi TV A Pro (2023) | 5.1 | Yes. | No. | There are problems with connecting MacBook |
| Xiaomi TV 6 (OEM models) | 4.2. or absent or | Depends on the region. | No. | In some countries, Bluetooth is disabled software |
If your model is not in the table, check for a Bluetooth module through the TV menu: go to Settings β On TV. β Specifications: If you don't have Bluetooth, but you see an antenna port (e.g., on older Mi models). TV 4S), This means that the module is available, but disabled by the manufacturer, in which case only an external Bluetooth adapter (we will talk about it in section 4) will help).
β οΈ Note: Xiaomi TVs released before 2019 (e.g. Mi) TV 3 or Mi TV 4 without the "Pro" console, as a rule, do not have built-in Bluetooth. Attempts to connect to them through this protocol will lead to the error "Device not found".
2. Preparation of the laptop for broadcast via Bluetooth
Before pairing devices, make sure your laptop meets the minimum requirements:
- π₯οΈ Operating system: Windows 10/11 (version 1903+) macOS 10.15+. Linux will require additional drivers (pulseaudio-module-bluetooth).

If your laptop doesn't see a Xiaomi TV in the list of available devices, the problem may be in Detection Mode. On the TV, go to Settings β Bluetooth β Visibility and activate the Detectable for All option for 2-5 minutes. Also make sure the distance between the devices is less than 3 meters - walls and furniture can block the signal.
3. Step-by-step instruction: how to connect a laptop to Xiaomi TV Bluetooth
Consider two scenarios: audio transmission (using the TV as a Bluetooth speaker) and presentation management (laptop as a remote).
Scenario 1: Using Xiaomi TV Bluetooth-like
- On Xiaomi TV, open Settings β Sound. β Sound output β Bluetooth audio.
- Select "Add device" and wait until the TV is detectable.
- On a laptop in the Bluetooth panel, find the name of your TV (e.g., "MiTV-XXXX") and click "Connect".
- After pairing in the laptop sound settings (Parameters) β System system β Sound) select the TV as the output device.
If the sound is interrupted or delayed, try:
- π Switch codecs in Bluetooth settings (on Windows: Control Panel) β Devices and printers β Device properties β Services: The best option β SBC or AAC.
- πΆ Reduce the distance between devices and remove obstacles.
- π Connecting a laptop to a 220V network increases the power of a Bluetooth transmitter.
Scenario 2: Managing presentations from a laptop
To use the laptop as a remote:
- Install the "Mi Remote Controller" app on your TV (available from the App Store on your TV).
- In the application settings, activate the "Bluetooth remote".
- On a laptop, connect to the TV as if to HID-device (manually select the type of device when pairing).
β οΈ Note: On some Xiaomi models TV (Like Mi. TV P1) The Bluetooth remote only works with the official Mi Remote app on your smartphone. The workaround is to use a USB-Bluetooth adapter with support for the device. HID-profile.

If the TV doesnβt appear in the list of Bluetooth devices, try resetting its network settings: β System system β Reset β Reset the network settings. After the reboot, try again to connect.
4. Alternative methods: if Bluetooth does not work
If your Xiaomi TV doesnβt support Bluetooth or the connection is constantly breaking, consider these options:
1. External Bluetooth adapter for TV
Connects to the port. USB 3.5 mm AUX (Popular models for sound:
- π Avantek USB Bluetooth 5.0 β Supports aptX Low Latency (minimum latency).
- π§ 1Mii B06 Pro β optimized for TVs, works as a transmission and receiver.
- πΆ TP-Link UB500 β budget option, but requires manual codec configuration.
Instructions for setting:
- Connect the adapter to USB-television-port.
- In the TV menu, select the sound source "USB" or βExternal device".
- On a laptop, connect to the adapter as a normal Bluetooth speaker.
2. Hybrid solution: Bluetooth + Wi-Fi Direct
Some Xiaomi models TV (Like Mi. TV 5) support Wi-Fi Direct for broadcasting the screen, but you can use Bluetooth for sound:
- Activate Wi-Fi Direct on your TV (Settings) β Network β Wi-Fi Direct).
- Connect your laptop to your TV via Wi-Fi Direct (as an access point).
- For sound, use Bluetooth pairing (Section 3).
The disadvantage of the method is that the synchronization of sound and video can be confused. VLC kodi).
3. Policy solutions for Windows/macOS
If you want to broadcast the entire screen, not just the sound, use:
- π₯οΈ AirParrot 3 (paid) β supports screen transfer over Bluetooth + Wi-Fi.
- π Miracast (built into Windows) 10/11) β requires television support.
- π Apple TV+ (for macOS β if you connect Apple TV Xiaomi TV through HDMI.

5. Problem Solving: Sound delay, communication breaks, errors
The most common complaint in Bluetooth broadcasts is assinchronicity of sound and video. Here's how to fix it:
| Problem. | Reason. | Decision |
|---|---|---|
| Video sound is 0.5-2 seconds behind video | Bluetooth codecs (especially) SBC) have high latency | Switch to aptX Low Latency or AAC sound-tuning |
| The connection is constantly breaking. | Interference from other devices (Wi-Fi, microwaves) | Switch Wi-Fi on your TV to 5GHz, turn off other Bluetooth devices |
| TV can't see a laptop | Outdated drivers or profile conflict | Update Bluetooth drivers on your laptop, reset your network settings on your TV |
| The sound is interrupted when moving. | Weak Bluetooth signal | Use it. USB-extension for Bluetooth adapter to bring it closer to the TV |
For manual synchronization of sound in players:
- V VLC: Tools β Effects and filters β Synchronization β Delayed audio (set the value from the -200 before +200 miss).
- In Kodi: Settings β Player. β Synchronization β Correction of audio delay.
- In Windows: Use Bluetooth Audio Receiver for fine-tuning.
β οΈ Note: Xiaomi TVs with firmware older than 2021 may not have the option of manually adjusting the sound delay, in which case only an external Bluetooth adapter with support for aptX will help LL.

If the sound delay is critical (for example, for games or movies), it is best to use the sound. HDMI-ARC or optical cable instead of Bluetooth. Bluetooth is only suitable for music or presentations without video.
6. Comparison of Bluetooth with other broadcasting methods
Bluetooth is convenient for its simplicity, but it's not always optimal.
| Method | Video quality | Sound quality | Delay. | Difficulty setting up | Energy consumption |
|---|---|---|---|---|---|
| Bluetooth | No transmission. | Mean (16-bit/44.1kHz) | High (200-500 ms) | Low. | Low. |
| Wi-Fi Direct (Miracast) | Full HD (1080p) | High (24-bit/48kHz) | Medium (50-100 ms) | Medium | High. |
| HDMI | 4K HDR | Maximum (up to) 32-bit/192kHz) | Minimum (<10 ms) | Low. | Low. |
| Chromecast/Google Cast | Full HD (1080p) | High. | Medium (100β200 ms) | Tall. | Average. |
| USB-C β HDMI (adapter) | 4K@60Hz | Maximum. | Minimum | Low. | Low. |
And you can see from the table that Bluetooth is losing out on all the things except power consumption and ease of setup, and it's only worth using in two cases:
- To transmit sound without video (e.g. listening to music through TV speakers).
- For presentation management where delay is uncritical.
In all other scenarios (films, games, video calls) it is better to choose Wi-Fi Direct or HDMI. If your Xiaomi TV supports you HDMI-CEC, You can use one remote control to control both a laptop and a TV - it is more convenient than Bluetooth.
