Xiaomi’s modern smartphones have become universal multimedia centers that allow not only communication, but also control the entire digital ecosystem of the home. One of the most popular features is the ability to display images and sound on the big screen, which greatly improves the experience of watching movies or games. Many users wonder how to establish a wireless connection between a gadget and a TV using built-in communication modules such as Bluetooth. Although this protocol is often associated with file transfer or headphones, its role in the smartphone-TV bundle can be both basic and auxiliary.
It is important to understand that live video from your phone to your TV exclusively via Bluetooth is technically impossible due to the low data rate of this protocol. The Bluetooth standard is primarily designed to transmit audio or use a smartphone as a remote control. For a full picture, Bluetooth + Wi-Fi Direct or Miracast technology is usually used. In this article, we will discuss in detail how to set up a connection, what restrictions are there and how to avoid typical errors when synchronizing devices from the Xiaomi brand and Mi TV or third-party panels.
Before you start setting up, make sure that both devices are charged and in line of sight from each other. Connection stability depends on the version of the MIUI or HyperOS operating system installed, as well as on the TV supporting the necessary A2DP or AVRCP profiles. We will look at all the nuances of the process so that you can enjoy content without delays and disconnects.
Bluetooth technology in the Xiaomi ecosystem
Bluetooth technology in Xiaomi smartphones has come a long way from version 4.0 to modern standards 5.2 and 5.3. The main advantage of this protocol is its low power consumption and the ability to quickly establish a connection between devices without complex network configuration. However, when it comes to multimedia, severe channel bandwidth restrictions come into force. This is why Bluetooth in conjunction with the TV is most often used to transmit audio stream or emulate the remote control, rather than streaming video content in high resolution.
Xiaomi devices have their own protocol stack, which is optimized for Mi Home home appliances. This allows the smartphone to instantly detect compatible TVs and offer interaction options. The audio transmission codec also plays an important role: support for aptX or LDAC provides high quality audio when connecting external acoustic systems via TV, bypassing the built-in speakers of the phone.
It’s worth noting that many users confuse “screencasting” with Bluetooth connectivity. In fact, when you press the broadcast button, the phone first uses Bluetooth to shake hands and share encryption keys, and then switches the main stream of data to a faster Wi-Fi Direct channel. Understanding this mechanics helps diagnose problems faster: if Bluetooth does not see the TV, then further broadcasting is impossible.

Preparation of devices for pairing
The first and most important step is to properly prepare both devices. Negligence in this step often leads to gadgets simply “not seeing” each other. Make sure that the TV is on detection and the smartphone is activated with the appropriate visibility mode. Often the problem is that one device already has a maximum number of gadgets or has outdated drivers.
To start with, you need to update the software. On Xiaomi smartphones, this is done through the Settings menu → About Phone → System Update. On a TV, especially if it is a Mi TV with a PatchWall shell or an Android TV, it is also worth checking for updates in the Settings section → About TV → System Update. Recent versions of the software contain vulnerability fixes and improved device search algorithms.
It is also important to clear the list of previously connected devices if there are too many. The excess of entries in the Bluetooth cache can slow down the search for new gadgets. Go to Bluetooth settings, find old or unnecessary connections, and select the option “Forget the device” or “Disable” that will free up the resources of the communication module and speed up the process of discovering a new TV.
Step-by-step instruction: pairing phone and TV
The process of connecting a Xiaomi smartphone to a TV via Bluetooth looks standard, but has its own nuances depending on the version of the MIUI shell. First open the swipe control panel down and activate the Bluetooth icon. Make sure the phone starts searching for available devices. At this time on the TV remote, click the button for setting the signal sources or go to the external device menu to start the pairing mode.
When your TV name appears on the list of available devices on your smartphone screen, click on it. The TV screen may request confirmation of pairing with or without the code. Confirm the action using the remote. After successfully connecting next to the device name, the Connected status or headphone/speaker icon will appear, which means that you are ready to transmit an audio signal.
What to do if the code does not appear?
If the confirmation request doesn't appear on the TV screen, try to initiate a new connection from your phone, pre-disabling Bluetooth for 10 seconds. PIN-a code that is usually 0000 or 1234 if the TV requires it to be.> To use your smartphone as a remote control, you may need to install an additional application, such as Mi Remote or Google Home. In the Mi Remote app, select Add Device, specify the type «TV» Follow the instructions on the screen, press the virtual remote buttons until the TV responds, and once you save the profile, you can control the volume and navigation directly from the phone screen. Sound transmission setting and media control After successful pairing, it is often necessary to redirect the audio stream. By default, sound can continue to go through the phone's speaker. To change this, open the sound control panel or go to Settings → Sound and Vibration → Output. In the list of available output devices, select your TV. This is especially true for watching video at night when you want to use a powerful TV speaker instead of a quiet smartphone speaker. Playback is controlled through the standard Google Play interface or the built-in Xiaomi player. When you connect Bluetooth, you have a button on the lock screen or in the notification curtain, the switching device is instantaneous, without breaking the connection. However, you should consider that when transmitting audio over Bluetooth, you can see a slight rhythm of the audio discharging, but you do not use the video clipboard, but you use the video clipboard. In the Mi Remote app or similar utilities, the smartphone screen area is transformed into a touchpad that repeats the movements of the cursor on the TV screen. This makes it easier to navigate the Smart TV menu, entering text for search on YouTube or Netflix becomes much faster than typing through the letters with the remote buttons. Screen broadcast: the role of Bluetooth and Wi-Fi Direct As mentioned earlier, it is not enough to transfer the image (Screen Mirroring) of Bluetooth alone. Here comes into operation Miracast technology or Google Cast protocol. Bluetooth in this scenario acts as a “key” that authorizes the connection while the mobile phone is running the heavy control channel. If your TV supports wireless display, it will appear on the list, and the connection process will begin after the selection, at which point it is important not to lock the phone screen or switch to other heavy applications, so as not to interrupt the handshake of the protocols. The quality of the image depends on the speed of the Wi-Fi module and the load of the air) HDMI-Adapter (wire) Transmission speed Low (up to 3 Mbps) High (up to 250 Mbps)+ Mbps: Maximum video quality Not supported by Full HD / 4K (compressed) 4K HDR Latency (for sound) Medium (noticeable in games) No battery consumption Minimum High charge phone In some cases, especially on older TV models, manual input may be required IP-addresses or use of third-party relay applications. Modern TVs Xiaomi Mi TV redmi TV Support automatic detection through the protocol DLNA, So that makes it as simple as possible for the user, and it's enough that both devices are on the same LAN. 💡Bluetooth is needed for primary pairing and audio transmission, but to broadcast the picture, the phone automatically switches to the faster Wi-Fi Direct protocol. Despite the simplicity of the technology, users often face a situation where the TV is not located or the connection is constantly broken. One of the most common causes is a conflict of Bluetooth versions or the presence of outdated profiles in the cache of the system. If the device is found but does not connect, try “Forget” it in the Bluetooth settings on both gadgets and start the procedure again. ⚠️ Warning: If after multiple attempts to connect the TV does not appear in the list, check if the router is not enabled mode "Customer isolation". AP». This feature prevents devices on the same Wi-Fi network from seeing each other, which blocks broadcast and detection functions. Another common problem is desynchronizing audio and video, which is treated by changing the settings in the Developer Menu on the phone. Find the option “Bluetooth audio delay” or “Bluetooth Bluetooth codec” and try to change the values. Also, it is worth turning off the power saving for the Bluetooth system process, since aggressive optimization is also worth it. MIUI If the sound is interrupted or has a characteristic interference, check if there are sources of severe radio interference: microwave ovens, running routers at 2.4 GHz or wireless mice. Transferring the router and smartphone to 5 GHz often solves the problem of connection stability by freeing up the air for Bluetooth. Using the smartphone as a universal remote Transforming the Xiaomi smartphone into a full-fledged remote control is one of the most convenient functions implemented through a combination of an IR port (if any) and Bluetooth. The built-in MI Remote application allows you to control not only the TV, but also the air conditioner, projector and receiver. For TVs without an IR port, it is a Bluetooth channel or Wi-Fi local network that is used. Setting the universal remote takes a virtual control from the screen, then you select a few options from the TV screen from the screen, and then you select a few options from the phone. This is especially useful when the physical remote is lost or its buttons have stopped responding. In addition to basic control, advanced users can adjust macros. For example, a single button "Cinema" can simultaneously turn on the TV, switch it to the desired one. HDMI-You can log in and run a YouTube app on your smartphone for broadcast, and this automation makes your smartphone a real smart home control center. Why can't your phone see a Bluetooth TV? Most of the time, the problem is that the TV isn't in pairing mode. On many models, you need to specifically activate the search in Bluetooth settings. TV. Also make sure that the phone is geolocated – this is a mandatory requirement for the Bluetooth scanner to work in Android? You can play, but the quality will be low due to the latency of input (input lag) and video stream. Bluetooth is not designed to transmit video in real time. For games, it is better to use wired HDMI connection or streaming via PC/console. Does Bluetooth connection affect Internet speed? Bluetooth itself operates at 2.4 GHz and can interfere with Wi-Fi at the same frequency that can theoretically reduce Internet speed. However, modern modules can coordinate work by minimizing interference. When using 5 GHz Wi-Fi conflicts, you do not experience "How to turn off the TV, simply switch off the switch off the switch on the switch on the switch on the TV, or switch off the switch off the device completely?" Does the Redmi Note 8 support video to TV? The Redmi Note 8 does not support video output via a USB-C (MHL) port, so wired connectivity is not possible. However, wireless broadcasting via Wi-Fi Direct and Bluetooth (for control) works normally through the Translation function in MIUI.
