Xiaomi’s current smartphones have high-resolution screens that are convenient to watch videos, flip through a photo gallery or show presentations. However, even the best-quality Mi Note or Redmi display can’t match the diagonal of a modern TV. Fortunately, wireless data technologies allow you to instantly stream an image from a mobile device to a large screen without unnecessary wires.
In this article, we will take a look at all the connectivity options available, from built-in Android system features to specialized applications, and learn how to set up Miracast, use the DLNA protocol for multimedia, or apply Google Cast technology to stream content from the Internet.
We will look at the nuances of working in the Xiaomi ecosystem, as the MIUI shell has its own features in the menu and item names. Proper setting will ensure a stable picture without delay, turning your smartphone into a powerful home theater control console.
Preparation of equipment and network
Before you start setting up your software, you need to make sure that the devices are physically ready to communicate. The fundamental condition for a successful connection is that the smartphone and the TV are on the same local network, which means that both gadgets must be connected to the same Wi-Fi router.
If your router supports dual-band operation (2.4 GHz and 5 GHz), it is recommended to connect both devices to a 5 GHz network. This range provides higher bandwidth, which is critical for transmitting a high-resolution 4K video stream without buffering.
- 📺 Make sure that the TV supports the Smart feature TV It has a built-in WiFi module.
- 📱 Check that the Xiaomi smartphone is Wi-Fi enabled and it is not in power saving mode.
- 🌐 Make sure the router does not block interaction between devices (function) AP Isolation must be disabled).
In some cases, antivirus software on a router or smartphone may block device detection on the network. If the connection is not established, try temporarily disabling the firewall or firewall for verification.
Broadcasting the screen through the built-in “Translation” function
The fastest way to display an image from a Xiaomi smartphone to a TV is to use the system’s “Translation” (or “Wireless Monitor”) function, which is based on the Miracast standard, which allows you to duplicate the screen in real time.
To activate, lower the notification curtain down and find the Translation icon. If it's not on the first screen, click the edit button (usually a pencil icon or three dots) and drag the icon to the active area. On some versions of MIUI, this feature may be called "Projection" or "Wireless display."
Once the feature is enabled, the smartphone will start searching for available devices, a request for permission to connect can appear on the TV screen — it must be confirmed by the remote control, and the image from the phone will appear on TV almost instantly.
☑️ Pre-broadcast checks
⚠️ Note: When using the screen duplication function, the smartphone can heat up more than usual, since the processor and WiFi module are working under high load.
The quality of the image depends on the power of the WiFi signal. If you notice the desynchronization of sound and video or artifacts on the screen, try to approach the router or reduce the output resolution in the broadcast settings.
Using the DLNA protocol for multimedia
If your goal is not to duplicate the entire screen of your smartphone, but to play a specific movie, music or show photos, the best solution is DLNA technology, which allows you to transfer media files directly to the decoder of the TV, freeing up the resources of the smartphone.
Unlike Miracast, here the phone acts as a remote control, and the TV itself decodes the video stream, which means that you can turn off the app or even lock the screen, and the playback on the TV will not be interrupted.
To implement this method, you will need a media server application. Xiaomi smartphones often pre-installed Mi Video player, which has built-in DLNA support. You can also use popular third-party solutions such as BubbleUPnP or AllConnect.
| Parameter | Miracast (Translation) | DLNA (Media) |
|---|---|---|
| Type of transmission | Screen streaming video | File transfer |
| Phone load | Tall. | Low. |
| Possibility of multitasking | No (screen is busy) | Yes (can use the phone) |
| Quality. | Depends on the WiFi signal. | Original File Quality |
When you select a file in a gallery or video player, look at the TV icon or the words "Cast." When you click on it, you'll see a list of available devices. Once you select the TV, playback will begin.
Applications for smart home Xiaomi
Xiaomi and Redmi owners can use the Mi Home (Mi Jia) app, which is a smart home management app, but also allows you to stream content to compatible TVs, especially if you have a Mi Box or a TV with Android TV built in.
To connect, open the app, make sure the region in the profile settings matches the region of the device, and click the + button to add a new gadget.
Secret features of Mi Home
Another powerful tool is the Xiaomi TV+ app (or PatchWall in some regions), which allows you not only to manage content, but also to use your smartphone as a full-fledged touch keyboard for typing, which is extremely convenient when searching for movies.
If you have a different brand TV but with Android TV support, make sure both devices are signed in to the same Google account, which syncs your browsing history and lets you send videos from the YouTube app on your phone to the TV with one touch.
Broadcasting via Google Home and Chromecast
The most versatile method, working on almost any modern TV (Samsung, LG, Sony, Philips), is to use Google Cast technology.
After installing the app and logging into your Google account, click the + button in the top corner and select Set up your device.
- 📲 Open the Google Home app on your Xiaomi smartphone.
- 📺 Select your TV from the list of available devices.
- 🖥️ Press the button "Cast my screen).
This method provides the most stable connection and better compatibility with services like YouTube, Netflix and Disney+.
💡
To reduce latency when playing games or presenting via Google Cast, close all background apps on your smartphone and turn off downloads to free up your WiFi channel.
It is important to note that when streaming via Google Home, the smartphone screen may not rotate automatically if the TV does not support the appropriate resolution, in which case, turn the screen autorotate in the Android settings.
Third-party broadcast applications
If standard methods don’t work or your TV is an older model, third-party apps from the Google Play store will come to the rescue, often with more flexible codec settings and support older protocols.
One of the leaders in this niche is the Web Video Caster app, which allows you to stream videos directly from websites without downloading files to your phone, just copy the link to the video or open it in the app's built-in browser.
Another popular solution is LocalCast, which is great at playing video files stored in your phone's memory or on the NAS network storage, and it automatically selects the right codec for your TV.
⚠️ Warning: Free versions of third-party apps often contain ads that may override the control screen. Be careful when pressing buttons so you don't accidentally start installing unnecessary software.
Also worth mentioning is the TV Cast for Smart TV app, which specializes in sending web pages and videos from them to Samsung, LG and Sony TVs using their native browsers.
Troubleshooting and troubleshooting
Despite the simplicity of the technology, users often experience connectivity problems, the most common being “Device not found,” which means that 90% of the time, the phone and TV are connected to different networks (e.g., one to the guest WiFi network, the other to the main one).
Another common problem is desynchronization of audio and video, which occurs when the WiFi signal is unstable, try rebooting the router by disconnecting it from power for 10 seconds, and check if someone on your network is downloading heavy files (torrents, games).
If the image is twitching or has a low resolution:
- Get closer to the router.
- Switch the TV to a 5 GHz network.
- Close the extra apps on the Xiaomi smartphone.
💡
The stability of the wireless connection depends on the distance to the router and the absence of physical obstacles (concrete walls, mirrors) between devices.
In rare cases, the problem lies in outdated software: Check for firmware updates for the TV in its settings menu and update apps on your smartphone through the Play Market.
