Connecting Xiaomi TV to laptop via Bluetooth: a step-by-step guide

Modern multimedia systems require flexibility, and a laptop-TV bundle becomes the standard for viewing content in high resolution. Users often look for a way to wirelessly transfer data, believing that Bluetooth is a universal solution for any technology. However, in the ecosystem of Xiaomi Mi TV and Redmi TV, the implementation of this protocol has its own features, which you need to know before you start setting up.

It’s worth noting that Bluetooth in Xiaomi TVs is most often designed to connect peripherals like headphones, gamepads or keyboards, rather than live streaming video from a computer. However, there are methods of using this communication channel to transmit audio stream or emulate connection, which can be useful in certain Android TV use cases.

In this guide, we will take a closer look at how the wireless module works in your smart console or TV, and what are the real ways to interact with Windows or macOS. We will look at the standard system tools, hidden engineering menus and alternative options that will provide a stable connection without unnecessary wires.

Bluetooth technical limitations on Xiaomi TVs

Before you start setting up, it is important to understand the architecture of the Android TV operating system that Xiaomi devices run on.The Bluetooth protocol is implemented primarily as a receiver of signals from accessories, rather than as a transmitter of high-density multimedia content. This means that standard video transfer or screen mirroring directly through this channel is technically impossible due to low bandwidth.

But if your goal is to transmit sound to external speakers or to connect your laptop to a home acoustics audio source, it's a very easy task. MIUI for TV The functionality is extended to allow the TV to be used as a Bluetooth speaker, but this requires the correct configuration of both devices. A2DP (Advanced Audio Distribution Profile).

Many users confuse technology, expecting Bluetooth to do what Wi-Fi Direct or Miracast can do. To transmit a video stream to 4K or FullHD requires a channel width that classic Bluetooth can not provide. So if you see your laptop on the list of available devices, most likely, the system offers only contact information or small audio files, rather than running streaming.

⚠️ Warning: Attempting to force video transmission via Bluetooth emulators can lead to sound and image dissynchronization, as well as overheating of the TV’s wireless communication module.

However, for certain tasks, such as slide presentations or background music playback, this channel is justified. → Remote and accessories so that the system understands which gadget is the source of the signal.

Preparation of equipment and compatibility check

The success of the operation depends on the version of the operating system and hardware. Make sure that your Xiaomi TV has the current version of the software installed, as older builds may not have the necessary codecs or connection profiles. Check for updates in the Settings → About TV → System Update.

The laptop also needs training. 10/11 You need to make sure that the Bluetooth adapter drivers are working correctly and support the necessary profiles. Sometimes the built-in modules in budget laptops have limited functionality, and for stable operation may require external USB-Adapter with Bluetooth support 4.0 higher.

If the TV only supports 4.0 and the laptop is equipped with a module 2.1, the connection may be unstable or impossible to transmit high-quality audio.

The table below shows the main characteristics of the profile support in the various Xiaomi TV lines:

If your model is not listed, check the specifications in the About TV menu. The lack of A2DP profile support will make audio transmission impossible with standard system tools.

Set up Xiaomi TV to receive the signal

The first step is to activate the visibility of the device. Go to the main menu and select Settings. Find Remotes and Accessories (or "Add Accessory"), and this is where the TV goes into search mode and becomes visible to external devices.

In some versions of the PatchWall interface or the global firmware Android TV, the path may be different. Look for the gear icon in the upper right corner, then go to Devices and Connections → Bluetooth. Make sure the switch is in the on position.

Importantly, the TV can hold a limited number of devices in memory at the same time. If the list is busy, delete old or unnecessary connections by clicking on the device name and selecting Forget or Delete, which will free up the module resources and speed up the pairing process.

⚠️ Note: Do not try to connect more than two Bluetooth devices at once (e.g., gamepad and headphones), as this can cause interrupt conflicts and interface delays.

Once the search mode is activated, an animation or a list of devices available for connection will appear on the TV screen. If the laptop has previously been paired with this TV, it can connect automatically provided that Bluetooth is on both devices.

💡

If the TV can’t see the laptop, try rebooting the Bluetooth module on the TV by turning it off and on again in the settings without turning off the TV itself.

Connecting a laptop with a TV through Windows

Now, to set up your computer. On Windows, open the Start menu and go to Settings → Devices → Bluetooth and other devices. Make sure the Bluetooth slider is activated. Press Add Bluetooth or another device.

In the window that opens, select the type of device. To transmit audio, you most often need to select the Audio Device (earphones, speakers) item if you want to output sound from your laptop to your TV. If you plan to transfer files, select Everything else. Most media uses the former option.

The system will start searching for available devices. Your Xiaomi TV should appear on the list (often labeled as "Mi TV" or a model, for example, "L43M5-5ARU"). Click on the device name. A request may appear on the TV screen to confirm the pairing of the code - make sure the codes on the TV screen and laptop monitor match, and click Confirm.

Once successfully paired, the device list will have "Connected" status on the computer, but this does not guarantee audio transmission. You need to manually switch the playback device. Press the speaker icon in the tray (near the clock), select the arrow up and in the list of output devices specify your Xiaomi TV.

If the sound doesn't show up, check your privacy settings. In Windows 10/11, go to Settings → Privacy → Microphone and make sure that microphone access for apps is allowed (this is required for some communication profiles), although this is not always critical for audio output.

Using TV as Bluetooth speaker

One of the most popular scenarios is using a powerful speaker system on your TV to output sound from your laptop, which is true when watching movies on a small laptop screen when you want surround sound, and for this, you need to set the Xiaomi TV device as the default device in Windows audio settings after you connect.

Sound quality will depend on the codecs supported. Android TV usually supports SBC and AAC codecs. If your laptop and TV support aptX, the quality will be significantly higher, with fewer compression artifacts. You can check supported codecs in the model specifications or using third-party snails on Android.

You can also consider the possible latency when watching videos through a browser or local files, and you can use the audio delay feature in the player (for example, in VLC Media Player) to synchronize the picture and sound.

⚠️ Note: When using a TV as a Bluetooth speaker, the volume is adjusted simultaneously on a laptop and a TV. 80-90%, a Main adjustment to make from the computer keyboard.

For music applications like Spotify or Yandex.Music, the connection is normal. Just start the track after pairing, and the system will automatically direct the stream to external speakers.

Alternative methods of wireless connection

Because pure Bluetooth is limited, the best way to use a laptop-TV bundle is to use Wi-Fi. The Miracast protocol (called Wireless Display Connection) allows you to broadcast images and sound without the latency of Bluetooth.

To activate Miracast on Xiaomi TV, make sure both devices are on the same Wi-Fi network. On the TV, in the signal source menu (input button on the remote), select Wireless Monitor or Screen Mirroring. On your laptop, press Win + K, select the TV from the list and wait for the connection.

Another powerful tool is Google Cast (Chromecast built-in) technology, which means that if you have Google Chrome installed, you can click three dots on the menu, choose to Broadcast and send a tab or the entire screen to your TV, which ensures the best image quality and connection stability.

Also worth mentioning are third-party apps like AirScreen or Receiver for AirPlay, which can be installed from the Google Play Store on your TV. They emulate AirPlay or Miracast signal reception, expanding compatibility with various laptop operating systems, including macOS.

Resolving and solving problems

Even when set up correctly, there can be failures. If your laptop can't see the TV, try turning off the antivirus or firewall while you pair it. Often, network screens block device detection protocols.

Intermittent sound is often solved by turning off power saving for a Bluetooth adapter. In Device Manager, find your Bluetooth module, open properties, go to Power Management tab, and uncheck "Allow this device to be turned off to save power."

If the device is displayed as "Connected" but no sound, check Windows services. Press Win + R, enter services.msc, and find the Bluetooth Support Service. Make sure it is running and the type of startup is "Automatically".

💡

The stability of the connection depends not only on the drivers, but also on the absence of interference in the air (microwaves, routers on the 2.4 GHz channel).

In case of complete inoperability of the module can help reset network settings on the TV or remove the device from the list of conjugated on both gadgets with subsequent re-use.
