Many users of the Xiaomi ecosystem are wondering about the possibility of wirelessly transferring video content to the big screen. Often search queries feature a bundle of phone-TV and Bluetooth technology, but there is a common misconception: the blue tooth protocol was originally designed to transfer audio and small files, not for streaming high-resolution video.
If you try to find the standard Bluetooth Translation feature in your Mi TV or smartphone menu, you won't find it. The bandwidth in this case is too small to be comfortable watching movies even in low quality. But that doesn't mean wireless viewing isn't impossible, it just uses other, more powerful tools, which we'll talk about later.
In this article, we will discuss in detail why Bluetooth is not suitable for video, what technologies really work in conjunction with Xiaomi Mi TVs and how to set up a mirror display screen in a few minutes. You will learn about the nuances of Miracast, the benefits of the DLNA protocol and how to manage content through the Mi Remote application.
⚠️ Warning: Don't waste time looking for hidden Bluetooth settings for video - such a feature doesn't exist in media transmission standards.Trying to use third-party apps promising this could lead to malware installation.
Why Bluetooth is not suitable for video transmission
Bluetooth technology is the standard for short distances and energy efficiency, and its main goal is to connect wireless headphones, fitness bracelets or gamepads to a smartphone. The maximum data rate in current versions of Bluetooth 5.0-5.3 is about 2-3 Mbps under ideal conditions, but for video streaming this is critically low.
For comparison, Full HD video requires a stable channel of 5 to 10 Mbps, and 4K already more than 25 Mbps. Even a compressed stream will not pass through the narrow neck of a Bluetooth channel without constant buffering and loss of image quality, which is why Xiaomi engineers and other TV manufacturers use Wi-Fi Direct and Miracast.
Bluetooth also doesn’t support real-time audio and video synchronization protocols as accurately as specialized multimedia standards, and you’d get audio and picture desynchronization in seconds.
- 📉 Low channel bandwidth does not allow to transmit video stream without delay.
- 🔋 High power consumption when trying to force data transfer will quickly discharge the smartphone.
- 🚫 Lack of native support for video codecs in your Bluetooth profile A2DP (It is intended only for audio).
So if your goal is to stream a movie or a presentation, Bluetooth is a dead end. You need to switch to Wi-Fi networks that provide gigabit speeds and stable connectivity between devices.
Real alternative: Miracast technology and Wi-Fi Direct
The main competitor of wired connectivity in Xiaomi’s world is Miracast technology.It runs on top of Wi-Fi Direct, which means a direct connection between the phone and the TV without having to connect to a home router (although having a shared network makes it easier to set up).
On Xiaomi Mi TVs, this feature is often built into Android TV or PatchWall. You don't need additional cables to run. Just make sure the Wi-Fi module on both devices is active. The smartphone creates a virtual channel that transmits a compressed image of the screen in real time.
Miracast is much better than Bluetooth theoretically, supports up to 1920×1080 and even 3840×2160 (4K) on current models, and has minimal latency, allowing you to not only watch videos, but also show photo albums or games.
☑️ Checking before connection
Importantly, with active Miracast connection, the Internet speed on the phone can decrease, as the Wi-Fi module is busy transmitting video streams, but local transfer of files or videos from the device’s memory occurs without loss of quality.
Instructions: how to connect Xiaomi phone to TV
The wireless connection setup process takes no more than two minutes, and depending on the version of the MIUI shell or HyperOS, the menu items may differ slightly, but the logic of the actions remains the same.
First, you need to prepare the TV. On the Mi Remote, press the setting button or select the source of the Input signal. On the list of available connections, find the option "Wireless Monitor", "Screen Mirroring" or "Miracast", and after selecting the TV will go to standby mode.
The way to the TV menu: Settings → Network and Internet → Device Connection → MiracastNow take your smartphone. Lower the notification curtain and find the Translation icon (may be called Projection, Wireless display, or Cast). If it's not, add it through the Quick Settings panel editing. Click on it and the phone will start looking for available displays.
When your Xiaomi TV comes up, click on it. You can see a request on your TV to confirm your connection -- you can agree with the remote. The image from your phone will instantly appear on the big screen.
⚠️ Warning: If the phone can't see the TV, make sure they're not on a guest Wi-Fi network with client isolation «AP Isolation».
What to do if the connection is constantly broken?
Use of Mi Home and Chromecast
Xiaomi’s ecosystem offers more advanced management techniques than a simple screen mirror. The Mi Home app allows you to use your smartphone as a remote and media library, which is especially convenient when you need to run a video from a gallery or streaming service without displaying the entire interface of the phone on the screen.
The built-in Chromecast support on Xiaomi TVs (based on Android TV) allows you to stream content directly from apps. For example, if you are on YouTube or Netflix on your phone, you can click the broadcast icon and select TV, in which case the phone acts only as a remote control, and the video is downloaded by the TV itself over the Internet.
This approach saves battery power and frees it up for other tasks, and the video quality is automatically adjusted depending on the speed of your Internet connection, ensuring maximum clarity.
| Method | Quality. | Dependence on the phone | Delay. |
|---|---|---|---|
| Bluetooth | Not supportive. | N/D | N/D |
| Miracast | High (up to 4K) | High (screen is copied) | Minimum |
| Chromecast | Maximum. | Low (remote only) | Absent. |
| HDMI cable | Perfect. | Total dependency | Absent. |
Using the DLNA protocol through Mi Video or third-party players (such as MX Player) allows you to transfer video files stored in your phone’s memory directly to your TV over a local network, ideal for watching downloaded movies without losing quality.
💡
For better stability when broadcasting 4K video, connect the TV to the router via Ethernet cable, and use the phone over 5 GHz Wi-Fi.
Configure DLNA for file transfer
The Digital Living Network Alliance (DLNA) protocol is a standard that allows devices to share multimedia content across a single network, and unlike Miracast, it does not duplicate a screen, but transmits the video stream file itself.
To implement this method on a Xiaomi smartphone, the standard video application (Mi Video) is often enough. Open the desired file, click on the Translation icon (rectangle with waves) and select your Xiaomi TV. The TV will automatically launch the built-in player and start playing.
The advantage of DLNA is that the TV decodes video itself using its more powerful processor, which allows you to watch heavy files with high bitrates that the phone might not have pulled when mirrored.
- 📁 Support for subtitles (often external synchronization is required).
- 🎮 Possibility of control playback (pause, rewind) from the phone.
- 🔊 Multi-channel audio transmission without loss of quality.
If a standard player doesn’t see a TV, you can install third-party apps like BubbleUPnP or LocalCast that have more flexible device search settings on the network.
⚠️ Attention: When in use DLNA The format of the video file should be supported by the TV's codecs. If the TV can't open the file, convert it to the format. MP4 (H.264) or MKV.
Connection problems and their solution
Despite the simplicity of the technology, users may face difficulties, most often due to the different versions of Wi-Fi protocols or router security settings, and if the devices are on different subnets, detection will be impossible.
Another common reason is outdated software: Xiaomi Android TVs need to update the system and apps regularly. Check for updates in Settings → About TV → System Update.
It’s also worth checking your smartphone’s energy saving settings. Aggressive MIUI algorithms can kill background broadcasting to save battery, add the broadcast app to the exclusion list, or select No Limits mode.
💡
90% of connection problems are solved by restarting the router and checking that both devices are connected to the same Wi-Fi frequency (2.4 GHz or 5 GHz).
If nothing works, try resetting your network settings on your TV, which will delete all stored Wi-Fi passwords and configurations, which often helps to resolve software conflicts.
