Modern multimedia systems require flexibility in management, and users often look for ways to wirelessly integrate their devices. Connecting a Xiaomi TV to a computer opens up new possibilities for broadcasting content, managing presentations or using a TV monitor as an external speaker system. HDMI-cables remain the standard for high-definition video transmission, wireless protocols allow you to get rid of unnecessary wires and simplify interaction between gadgets.
A technical feature is worth noting right away: direct video transmission from a PC to a Xiaomi Mi TV or Mi Box exclusively via Bluetooth is technically impossible due to the low bandwidth of this channel. However, Bluetooth Low Energy is actively used to pair peripherals, set up a remote or transmit audio stream in certain scenarios. In this article, we will discuss all available methods of interaction where Bluetooth plays a key or supporting role, and consider alternative wireless solutions.
Understanding the Android TV architecture that Xiaomi TVs run on is critical to getting the right setup. The system shares connection profiles, and what works for headphones may not be suitable for file transfer. We will study the pairing process, the necessary drivers for Windows, and the nuances of working with codecs so that you can maximize the potential of your smart TV.
Technical limitations and capabilities of Bluetooth on Xiaomi TV
Bluetooth is often seen as a universal solution for any wireless communication, but in the case of Xiaomi TVs, its functionality is strictly regulated by the developers of the system. The main purpose of this module in TVs is to connect game controllers, keyboards, mice and sound systems. The channel bandwidth, even in version 5.0, is not enough to transmit uncompressed video stream FullHD or 4K without significant delays and loss of quality.
However, using a Bluetooth adapter on a computer can become a bridge to control a TV or transmit commands. For example, you can use a PC as a remote control or stream audio to an external Bluetooth headset connected to a TV, although the direction of the PC is not the same -> TV's are harder to implement for sound, and it's important to distinguish between media transfer and device management: the former requires Wi-Fi Direct or Wi-Fi Direct. DLNA, The second is very useful through standard HID-profiles.
⚠️ Note: Do not try to find the "Accept video over Bluetooth" function in the settings of the TV, since the hardware of Xiaomi TV This protocol does not support video transmission through this protocol, but this restriction is related to the physical characteristics of the standard.
To successfully implement any interaction scenarios, you need to consider the version of Bluetooth installed on your TV. Models from different years of release can be equipped with modules from 4.2 to 5.2, which affects connection stability and power consumption. Checking the specifications of your Mi TV Stick or Mi TV P1 model will help avoid frustration when trying to connect devices that require newer communication standards.
Why is Bluetooth 5.0 better for a smart home?
Equipment preparation and software
Before you start pairing, you need to make sure your hardware is ready to go. On the computer side, whether you're using Windows 10, Windows 11 or macOS, the Bluetooth module must be in good working order. USB-Adapters, because embedded motherboards don't always have wireless modules, drivers must be upgraded to the latest version available on the chipset manufacturer's website.
On the Xiaomi TV side, you also need to activate the appropriate services. Android TV has its own features of working with the visibility of the device. By default, the TV may not appear in the list of available devices on the PC until you force the pairing menu to open. This is a security measure to prevent unauthorized access to your device from outside.
- 📺 Make sure that the TV and computer are in the same room, within a radius. 5-7 meters for stable signal.
- 🔄 Update the TV firmware through the Settings menu → On TV. → System update.
- 💻 Check with Windows Device Manager that the Bluetooth adapter is error-free and marked as “The device is operating normally".
- 🔋 If you use a wireless adapter, connect it directly to the port. USB motherboard, avoiding long extension cords.
Special attention should be paid to codecs and file formats if your goal is to transmit media. Although Bluetooth is not the main channel here, the preparatory stage includes checking format compatibility. Xiaomi TVs work perfectly with MKV containers, MP4 and Dolby Audio audio codecs. Make sure that the necessary codec packages are installed on the PC if you plan to use combined data transfer methods.
☑️ Checking connection readiness
Step-by-step instructions for pairing devices
Connecting your computer to a Xiaomi TV via Bluetooth requires a sequential action. First, we activate visibility mode on the TV, as it is a passive device in this scenario. Go to the main menu, select Settings, then find Add Accessories or Remotes and Accessories. The TV will go into search mode, and its name (such as MI TV 4S) will be visible for scanning.
On your computer, open Bluetooth settings through the taskbar or the Start menu. Press the Add Bluetooth or other device button. In the window that opens, select the first "Bluetooth" option. The system will start scanning the ether. When your TV name appears in the list, click on it. On the TV screen, you may see a request to confirm the pairing with the code - make sure that the codes on the PC monitor and the TV screen match, and confirm the action with the remote.
⚠️ Note: If the system requests PIN-The standard options for Xiaomi devices are often 0000 or 1234 combinations, but modern Android is the most popular. TV Usually generates random code for security.
Once successfully paired, the device status will change to "Connected." However, this does not mean automatic image transfer. At this stage, a logical connection is established that allows you to exchange service data. Multimedia transfer may require additional actions, such as selecting a usage profile (A2DP for sound, HID for input). In some cases, Windows can define the TV as an audio device, but not as a display.
Sound transmission and control settings
One of the most effective Bluetooth scenarios for PC-Xiaomi TV is audio streaming. You can use the TV as external speakers for the computer, which is especially true if the monitor does not have built-in speakers or they are of poor quality. After pairing, you need to go to the Windows audio settings. Right-click on the speaker icon in the tray and select Open audio settings or Sounds.
In the playlist, find your Xiaomi TV. If it doesn't show up as an active device, right-click in the blank area of the window and select "Show Disabled Devices." Activate the TV and install it by default. Now all system sound, including music and sounds from browsers, will be streamed through the TV's speakers. The sound quality will depend on the codecs supported (SBC, AAC, aptX).
Another scenario is using a PC to control a TV, although here Bluetooth acts more like an auxiliary channel for the periphery. You can connect the keyboard and mouse to the TV directly, but if you want to emulate input from a PC, you will need specialized emulator applications running on top of a Bluetooth HID profile, which allows, for example, typing text to search YouTube on the TV using the full computer keyboard.
| Parameter | Bluetooth 4.2 | Bluetooth 5.0+ | Wi-Fi Direct |
|---|---|---|---|
| Transmission speed | up to 1 Mbps | up to 2 Mbit/ | up to 250 Mbps |
| Video transmission | Impossible. | Impossible. | Maybe (Miracast) |
| Delay (Latency) | Tall. | Medium | Low. |
| Range. | ~10 meters | ~40 meters | ~15 meters |
It's important to understand that when you transmit audio over Bluetooth, you can see that you can dissynchronize audio and video when you watch movies on the computer itself, a phenomenon called latency, which you can try to turn off power saving in your Bluetooth adapter settings, and in your TV settings, turn on Game or Sport mode, which often turn off excessive post-processing of sound.
💡
If Bluetooth audio is interrupted, try turning off the power saving circuit for the Bluetooth adapter in Windows Device Manager, which often solves the audio stuttering problem.
Alternatives: Wi-Fi Direct and Miracast for screen broadcasting
Since direct display over Bluetooth is not possible, you need to use Wi-Fi technologies to broadcast your computer screen to your Xiaomi TV. In Windows 10 and 11, this feature is implemented via the Miracast protocol. Xiaomi TVs support this technology out of the box. To start the broadcast, make sure that your PC and TV are connected to the same Wi-Fi network, although direct connection (Wi-Fi Direct) may not be required, but the network must be active.
Press the Win + K keyboard on your computer. The Connect panel will come out on the right. Your TV should appear in the list of available displays. The handshake process will begin when you select, and the TV screen will request permission to connect. Take it from the remote. The desktop or extended screen image will appear on the large display.
The advantage of using Wi-Fi over Bluetooth is enormous: you get up to 4K video streaming, HDR and multichannel audio support, Wi-Fi bandwidth allows you to stream video at bitrates of up to 20-30 Mbps, which is ten times higher than Bluetooth, which makes it possible not only to view photos, but also to fully work with documents or demonstrate presentations.
If the standard Windows tool doesn't see a TV, you can use Google Chrome. Open the menu (three dots in the corner), select "Translate" (Cast). In the window that appears, select "Translate the whole screen" or "Translate the tab." Chrome uses Chromecast built-in technology, which is natively built into the shell of Android TVs Xiaomi, providing a stable connection even over the Internet.
💡
Always use Wi-Fi (Miracast/Chromecast) to transmit video, as Bluetooth is not physically capable of transmitting high quality video streams without critical delays.
Solving and diagnosing problems
Users may encounter various difficulties in setting up, and one of the common problems is that the computer does not see the TV in the list of Bluetooth devices, which may be because the TV is already paired with another device (like a smartphone) and does not go into detection mode. Solution: go to the Bluetooth settings on the TV, find a list of paired devices, delete the old ones or turn them off, and re-start the search.
Another common problem is unstable connections or persistent breaks. Radio interference is often the culprit. Bluetooth operates at 2.4 GHz, like many Wi-Fi routers and microwave ovens. If the router is close to the TV or PC, it can jam the signal. Try to switch the router to 5 GHz mode or move the devices away from each other. Also check if the PC has Bluetooth programs from third-party manufacturers that may conflict with the standard Windows stack.
- 🔍 Problem: Sound is there, but video is slowing down.Solution: This is normal for Bluetooth, use Wi-Fi for video.
- 🔍 Problem: TV is not defined as an audio device Solution: Update Bluetooth drivers and check Windows Audio services.
- 🔍 Problem: High input latency in games Solution: Bluetooth is not suitable for gaming, use a wired connection or Wi-Fi.
If nothing works, you can try resetting the network settings on your TV. Go to Settings → Network and Internet and reset. Also, an effective method is to completely reboot both devices with a disconnection from the power grid for 1-2 minutes, which allows you to clear the cache of communication modules.
⚠️ Note: When you reset your TV network settings, you may lose saved Wi-Fi passwords and other Bluetooth accessories, so you will need to reset your Wi-Fi passwords.
