Xiaomi’s current smart TVs, which are powered by Android TV or PatchWall, offer a wide range of opportunities to integrate into the home ecosystem. Users often wonder how to wirelessly connect between a TV and a Windows 10 PC to stream media, display images or transfer files without cables. Although Bluetooth technology is associated primarily with peripherals like mice and keyboards, its role in the context of televisions is often misstood, and video transmission is more often required by other protocols.
In this guide, we will discuss in detail the process of configuring the communication between a Xiaomi Mi TV or Redmi TV and a PC, we will find out whether direct streaming of video via Bluetooth is possible, or whether it is worth looking at more effective methods like Miracast and DLNA, which also use wireless interfaces. Understanding the network architecture and capabilities of the Bluetooth module in the TV will help to avoid common mistakes and frustrations when trying to sync devices.
To get started, you need to make sure that both devices are on and within the safe receiving zone. The computer needs to be running the current version of Windows 10 with security updates installed, and the TV needs to be connected to the same local network if we're talking about combined data methods. Let's look at the technical nuances that determine the success of the operation.
Bluetooth Technical Limitations for Video Transmission
Before pairing, it is important to understand the physical limitations of the technology: Bluetooth channel bandwidth is far inferior to Wi-Fi, especially in 5 GHz bands. The standard data protocol is not designed to stream high-resolution video in real time without strong compression, resulting in delays and loss of quality.
In Xiaomi TVs, the Bluetooth module is primarily designed to connect audio devices (headphones, soundbars) and input devices (remotes, gamepads). Trying to use it as the main channel for broadcasting desktop or movies can encounter codec incompatibility. Windows 10 also limits the functionality of Bluetooth profiles for displays, preferring Wi-Fi Direct standards.
⚠️ Note: Don’t expect high performance when trying to broadcast 4K-Videos are exclusively via Bluetooth. Always use the quality image. HDMI or wireless technologies based on Wi-Fi.
However, for the transmission of static images, documents or control of a media player Bluetooth is ideal. The table below shows a comparison of the bandwidth of the different wireless interfaces available in modern TVs.
| Interface. | Maximum speed (theor.) | Appointment in Xiaomi TV | Support for video |
|---|---|---|---|
| Bluetooth 4.2/5.0 | up to 3 Mbps | Sound, remotes, files. | No (only compressed) |
| Wi-Fi 2.4 GHz | up to 150 Mbps | Streaming, DLNA, Cast | Yes (Full HD) |
| Wi-Fi 5 GHz | up to 866 Mbps | 4K HDR, games, Cast | Yes (4K HDR) |
| HDMI 2.1 | up to 48 Gbps | Wired connection | Yes (8K 120Hz) |
Preparation of equipment and software environment
Successful device integration starts with proper preparation. Make sure your Windows 10 computer has a Bluetooth adapter activated. In laptops, it's often built-in, whereas desktops may require an external one. USB-You can check the availability of an adapter through Device Manager by finding the corresponding section in the equipment list.
On the Xiaomi TV side, you need to activate Visibility Mode. To do this, go to the Settings menu, select Settings, then find the Bluetooth partition and turn it on. Make sure the TV is not in Power Saving Mode, which can turn off the wireless module to save resources.
It is also critical to update your Bluetooth drivers on your computer. Go to the motherboard or adapter manufacturer's website and download the latest version of the software. Outdated drivers can cause unstable connections or no visibility of devices in range.
☑️ Checking connection readiness
If you plan to use combined transmission methods, make sure both devices are connected to the same Wi-Fi network.This is a requirement for the DLNA and Miracast protocols, which are often used in conjunction with Bluetooth for control.
Step-by-step instructions for pairing devices
Connecting a Xiaomi TV to a Windows 10 computer requires a consistent process. First, activate device search on the TV. The Bluetooth menu on the TV screen should show a list of gadgets available for connection. If your computer does not appear, check your privacy settings in Windows.
On your computer, open the notification center by pressing the Win + A key combination and make sure the Bluetooth button is blue. Right-click on the Bluetooth icon in tray or go to Settings → Devices → Bluetooth and other devices. Press the Add Bluetooth button or another device.
In the window that opens, select the first Bluetooth option. The system will start searching for available devices. Your TV should appear in the list, often labeled as an Android TV or a specific model, such as MI TV 4A. Click on the device name to begin pairing.
⚠️ Note: If the system requests PIN-code, make sure the numbers on the TV and computer screen match. Confirm the connection on both devices using the TV remote and the PC mouse.
Once the device is successfully paired, the status of the device will change to Connected, but this does not mean that the image is broadcast; at this stage, only the basic connection for data exchange or management is installed.
What to do if the device is not found?
Screen and multimedia broadcasting (Miracast and DLNA)
Because pure Bluetooth does not transmit video streaming at high speed, Miracast technology (called Connect in Windows) is used to output desktop or movie images. This is a Wi-Fi Direct standard that allows you to transfer video without a router, directly between devices.
To start the broadcast, click on the computer keyboard the combination Win + K. On the right will appear the panel "Connect". In the list of available displays, select your Xiaomi TV. On the TV screen, you may see a request for permission to connect, which you need to confirm by remote control.
To transfer files and media (photos, videos, music), you should use the DLNA protocol. In Windows 10, this feature is built into the media player. Open the desired video file, right-click, select Transmit to the device and specify your TV. The file will play on the big screen.
💡
To reduce latency when playing or working through Miracast, connect both devices to the router via an Ethernet cable or use the 5GHz Wi-Fi band.
Importantly, Miracast broadcast quality is directly dependent on the power of the Wi-Fi signal. If you notice artifacts or audio desynchronization, try bringing your computer closer to your router or TV. Some Xiaomi models also support built-in Chromecast, allowing you to stream the Chrome browser tab directly.
Using Bluetooth to transfer files and control
Although weak for video, Bluetooth is great at transferring documents, photos and music, and Windows 10 uses Send or Receive Files to do this. Go to Start → Settings → Devices → Send or Receive Files via Bluetooth.
Select Send files, find a Xiaomi TV paired in the list, and select the file you want. The TV screen will request acceptance of the file. Once confirmed, the file will be saved in internal memory or on a connected drive.
Bluetooth also allows you to use your smartphone or PC as a remote control if you have an emulator installed, which is convenient when the physical remote is lost or its batteries are out of order, and the computer acts as a keyboard for typing text in a YouTube search or browser.
💡
Bluetooth in a PC/TV bundle is ideal for managing and transferring files, but for video, always switch to Wi-Fi Direct (Miracast) or HDMI.
Solving Common Connection Problems
Often, users are faced with a situation where devices see each other, but the connection is not established. One of the reasons may be a crowded Bluetooth cache on the TV. Try to remove the device from the list of paired on TV and perform the procedure again.
Another common problem is Bluetooth version conflict: if your computer is equipped with an older version of the standard (e.g., 2.1 or 3.0) and your TV requires 4.0.+, You can't run stable. Check your specifications. USB-adapter and, if necessary, replace it with a more modern one.
Also worth mentioning is interference: Working microwaves, wireless phones, and neighboring Wi-Fi networks can make noise on the air, try turning off other wireless devices, or move the router away from line of sight between PCs and TVs.
⚠️ Warning: If after all the manipulations, the sound is coming through the PC speakers, not through the TV, check the audio output settings. Click on the speaker icon in the Windows tray and select the Xiaomi output device in the list TV or hands-free AG Audio.
Alternative methods of wireless connection
If standard methods don't work, you can use third-party software, like AirDroid, TeamViewer, or specialized software. DLNA-Servers (like Plex) allow you to organize a powerful media system, and they bypass the limitations of standard Windows protocols.
For gamers, the question of connecting a PC to a TV for games is relevant. Bluetooth is not suitable for this because of delays (input lag). Use a wired HDMI connection or Steam Link technology, which is optimized to transfer a game video stream over a local network with minimal latency.
Owners of the Xiaomi ecosystem can also use the Mi Home app on a PC (via an Android emulator) or smartphone to deep-tube the TV, although there is no direct screen stream from the PC through this app.
