Modern users are rarely content with watching content only on a small smartphone screen. Huge movie libraries, personal photo archives and mobile games are much more enjoyable on a large diagonal. Xiaomi ecosystem owners are in a favorable position, because the integration between the brand devices is implemented as deeply and conveniently as possible.
There are several proven synchronization methods, each with its own advantages depending on the situation. Wireless technologies like Mi Cast and DLNA are ideal for fast transfer of photos or videos from the Internet, while wired connection via HDMI guarantees maximum stability and minimal latency. The choice of the particular method depends on the model of your TV, the version of the Android operating system or MIUI TV, and also on the availability of free access to the router.
In this guide, we will take a look at all the current connectivity options, from standard system functions to third-party applications. You will learn how to avoid common errors such as sound desynchronization or no image. Proper network configuration is the foundation for the success of any wireless data protocol.
Device Preparation and Network Requirements
Before any manipulations begin, you need to make sure that both devices are ready to interact. A critical condition for most wireless protocols is to have a smartphone and a TV on the same local network. This means that both gadgets must be connected to the same Wi-Fi router. If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, it is desirable that both devices use the same frequency, although modern routers often combine them into the same network.
Check the software's relevance on both devices. On a Xiaomi Mi TV or Redmi TV, you can do this through the settings menu by finding the About Device → System Update. On a smartphone, the path usually looks like Settings → About Phone → MIUI Version. Outdated firmware versions may contain bugs that block device detection on the network.
⚠️ Note: If your smartphone distributes the Internet through a mobile access point, and the TV is connected to this point, the broadcast may not work stable or not work at all due to restrictions. NAT. It is better to connect both devices to a fixed home router.
It's also worth checking your power saving settings. Aggressive MIUI algorithms can lull the background processes that search for devices. It's recommended to temporarily turn off power saving mode or add a broadcast app to exceptions. Make sure your TV is on Wi-Fi Direct, or a detection feature that's often active by default but may have been disabled by the user before.
Wireless streaming via Mi Cast and Miracast
The most popular and convenient method for owners of Xiaomi equipment is the use of the built-in Mi Cast function. This protocol is based on the Miracast standard, which allows you to transfer the image of the smartphone screen to the TV in real time. The peculiarity of the technology is that it does not require the mandatory availability of the Internet, only a working local Wi-Fi network for the handshake process (handshake devices).
To start the process on the remote control of the TV, find a button with a smartphone image or data icon. In the signal source menu (Source or Inputs), select Mi Cast or Wireless projection. The screen will display a waiting interface connection with the name of the device and QR-On your smartphone, open the notification curtain and find the Broadcast button (or Cast, Wireless Monitor) and the system will automatically scan the network and prompt you to select your TV.
Once connected, the image from the phone is completely cloned onto the big screen, allowing you to show presentations, play games, or just flip through the social media feed, and it's important to understand that when connected, the smartphone continues to consume battery power, so it's better to charge it for long sessions.
- 📱 Open the “Control Center” on your smartphone swipe down from the upper right corner.
- 📺 Click on the broadcast icon (rectangle with triangle).
- 🔍 Wait for the name of your Xiaomi TV to appear in the list of available devices.
- ✅ Click on the title to initiate the connection and mirror the screen.
The quality of the image depends on the power of your router and the distance to it. When using the 5 GHz standard, the delay is minimal, which is important for dynamic games. If you notice artifacts or jerks, try to get closer to the router or free the Wi-Fi channel from other active downloads.
💡
For games with high reaction requirements (shooters, racing), use wired connection or Game mode in the TV settings to reduce Input Lag (entry delay).
Multimedia streaming via DLNA and YouTube
If your goal is not to duplicate the screen, but to play a specific video file, photo or music track, it is better to use DLNA technology. This method is more energy efficient, since the smartphone acts only as a remote control, and the TV processor decodes the video, which allows you to watch content in high resolution (up to 4K) without jerking, even if the smartphone screen is turned off.
Most video viewing apps, such as YouTube, VK Video, Netflix or Xiaomi's built-in video player, have built-in DLNA support (often labeled as Google Cast). Open the video on your smartphone, click on the broadcast icon (rectangle with waves) in the corner of the player and select a Xiaomi TV from the list. buffering occurs on the TV side, so the picture quality will be stable.
To play local files downloaded to the phone’s memory, you can use third-party media center applications, such as Xiaomi Mi Remote (in media mode) or universal players like VLC for Android. They can see DLNA devices on the network and send content to them. The standard Gallery app on MIUI phones also has a broadcast button when opening a photo or video.
| Characteristics | Mi Cast (Miracast) | DLNA / Google Cast |
|---|---|---|
| Type of transmission | Screen mirroring | The flow of multimedia |
| Dependence on the phone | High (screen active) | Low (can be rolled) |
| Battery consumption | High-pitched | Minimum |
| 4K support | Depends on the TV model. | Yes (if there is content) |
⚠️ Note: Some applications with protected content (DRM), such as paid subscriptions in cinemas, can block the transmission of images through DLNA, It's normal behavior to do copyright protection, but it's only sound or black screen.
Wired connection via HDMI and USB-C
When wireless connectivity is impossible or maximum picture quality is required without compression, a cable comes to the rescue. The modern Xiaomi smartphone is most often connected to a TV with a USB-C to HDMI adapter. However, there is an important caveat: the USB-C port in the phone must support a video transmission standard known as MHL or DisplayPort Alt Mode.
Not all smartphone models, even flagship ones, support cable output. Redmi budget series and some Poco models often lack this feature at the hardware level. Before buying an adapter, it is strongly recommended to check the specification of your particular model on the official website or in the technical profile on GSMArena. If there is support, the connection is Plug-and-Play: inserted the cable into the phone and into the free HDMI port on the TV, switched the signal source to the TV.
☑️ Checking before buying the cable
The advantage of the wired method is that there are no delays and they depend on the speed of Wi-Fi. You can broadcast the image in the native resolution of the smartphone screen. If the phone supports charging while you're running, some expensive HDMI docks allow you to charge the gadget at the same time, which is convenient for viewing.
Use of Mi Remote and IR port
Special attention should be paid to controlling the TV through an infrared port (IR), if it is in your Xiaomi smartphone. This does not broadcast the image, but turns the phone into a full-fledged remote control, which is often required for initial settings or if the regular remote is lost. Mi Remote is preinstalled on most devices of the brand and contains a database of codes for thousands of models of equipment.
To set up, open the app, click Add Device, and select TV. From the brand list, find Xiaomi or MI TV. Follow the on-screen instructions: the phone will send test signals, and you need to confirm the TV's response with either Yes or No buttons. Once successfully paired, you can control volume, signal sources, and navigation in the menu directly from the smartphone screen.
This method is especially useful if the Wi-Fi network is temporarily unavailable because the IR port is autonomous, but for Screen Translation or DLNA functions, a working Wi-Fi network will still be required, since the IR channel is too narrow to transmit a video stream.

Solving Connection Problems and Errors
Despite the simplicity of the technology, users often face a situation where the TV simply “can’t see” the phone. First of all, check if the router is activated customer isolation (AP Isolation), a security feature that prevents devices within the same Wi-Fi network from communicating with each other, which blocks the work of Mi Cast and DLNA. You can turn it off in the router settings via the web interface (usually at 192.168.0.1 or 1.1).
Another common problem is to desynchronize audio and image when wirelessly broadcasting, which is treated by rebooting both devices and the router. Also try to find Settings → General → Image Mode in the settings of the MIUI TV and switch it to Movie or Game, which can change the algorithms for processing video streams.
If you have an image on HDMI but no sound, check your audio output settings in Android. Sometimes the default system leaves sound on your phone. Go to Settings → Sound and Vibration → Output (the path may differ in different versions of MIUI) and force HDMI.
- 🔄 Restart the router by pulling the power cord for 10 seconds.
- 📡 Make sure that both devices have Bluetooth enabled (it helps with initial detection).
- 🛡️ Check if the antivirus or firewall on your phone is blocking local connections.
- ⚙️ Reset your network settings on your TV through Settings → Network → Reset.
⚠️ Note: When using cheap Chinese adapters HDMI If the screen is black, try changing the resolution or refresh rate manually in your phone settings (Screen section) if this option is available in the engineering menu or advanced settings.
💡
90% of connection problems are solved by simply restarting the router or transferring devices to a single frequency network (2.4 GHz or 5 GHz).
