Modern Xiaomi smartphones have powerful screens and multimedia capabilities, but for a comfortable viewing of movies in 4K or a demonstration of a photo album of a large company, the display of a gadget may not be enough. Fortunately, wireless data technologies allow you to instantly broadcast an image to the big screen without unnecessary wires and complex settings. Owners of the Xiaomi ecosystem have several native tools and third-party solutions to implement this task.
In this article, we’ll look at all the current ways to connect, from built-in MIUI features to customized applications, how to set up Miracast and DLNA, why audio sometimes goes missing, and how to achieve minimal latency when streaming games. We’ll also look at the nuances of working with TVs from different manufacturers so you can enjoy content in the maximum quality.
Preparing devices for wireless connection
Before you start setting up, you need to make sure that both devices are in the same network conditions. The most critical factor is that the smartphone and TV must be connected to the same router. If your router supports dual-band, it is advisable to use a 5 GHz network for high-resolution video transmission, as it provides higher bandwidth.
Check the software's up-to-date on both devices. Android TVs or Smart TVs often require system component updates to ensure that detection protocols work properly. Make sure that Wi-Fi is active and stable, as interrupting the signal even for a split second can lead to a picture being out of sync.
Also worth paying attention to the power saving mode of the smartphone. Aggressive battery optimization in the shell of MIUI can block background data transfer processes. It is recommended to turn off the energy saving mode for the duration of the viewing or add the broadcast app to the list of exceptions so that the system does not “fall asleep” during operation.
☑️ Checking before connection
Use of the built-in Translation (Miracast) function
The most versatile way is to use Miracast technology, which is built into most modern Xiaomi TVs and smartphones, which allows you to duplicate the phone screen on the TV in real time, which is ideal for watching videos from browsers that do not support direct output, or show games.
To run the feature on Xiaomi smartphones, you need to open the control center. Swipe down from the top right corner of the screen (or left, depending on the navigation settings) to open the notification curtain. Find an icon called "Translation" or "Cast." If the icon is not visible, click on the edit button (usually three dots or a pencil) and drag the desired widget to the desktop.
Once activated, the phone will start searching for available devices. The TV may need to run an app that is often called Miracast, Screen Share, Wireless Display, or simply Translation. Select the name of your TV from the list on your smartphone, and in a few seconds the image should appear on the big screen.
⚠️ Note: When using Miracast, the image from the phone may not scale to the entire TV screen, keeping the proportions of the mobile display.
💡
If your phone can't see the TV, try restarting your router. DHCP-server prevents the correct identification of devices in the local network.
Broadcasting through the Xiaomi Mi TV Assistant app
For owners of TVs with support for Android TV or Mi Box, Xiaomi has developed its own application Mi TV Assistant (formerly known as Mi Remote), which allows you not only to control the TV as a remote, but also to perform advanced broadcast media files.
Download the app from Google Play and run it. The program will automatically scan the network and suggest connecting to the found TV. Once you confirm the pairing (the code that you can enter on the phone on the TV screen may appear on the TV screen), you will be able to access the Translation or Cast section.
Unlike simple screen duplication, this method often allows video files to be transferred directly using a TV decoder, which reduces the load on the smartphone processor and saves battery power, so you can select videos, photos or music from your phone's memory and send them to your TV.
- 📺 Support for playback control from the phone (pause, rewind).
- 🔋 Less power consumption of a smartphone compared to full screen duplication.
- 📂 The ability to transfer files of different formats without prior conversion.
Using Chromecast Technology and Google Home
Many modern TVs have built-in support for Chromecast built-in. This is a technology from Google that allows you to stream content from apps directly to the TV. To work, you will need the Google Home app, which is often pre-installed on Xiaomi smartphones.
Open the Google Home app and find your TV in the device list. Click on the TV icon and then select the "Cast my screen" button, a technique that is particularly good for streaming services like YouTube or Netflix, as it initiates direct video downloads from the TV from the Internet rather than from your phone.
The main advantage of Chromecast is stability, and if you run a video through the Cast button inside the YouTube app, you can even turn off your phone screen or go to other apps, and playback on the TV will not be interrupted.
To set up, make sure that notifications and permissions to access the local network are enabled in the Google Home app. Without these permissions, the app will not be able to detect the TV on your home Wi-Fi network.
| Parameter | Miracast (Translation) | Chromecast (Google Home) | DLNA (Mi TV) |
|---|---|---|---|
| Type of connection | Screen duplication | Streaming | File transfer |
| Dependence on the phone | High (screen on fire) | Low (can be rolled) | Medium |
| Quality. | Depends on the Wi-Fi signal. | Maximum (4K HDR) | Original |
| Battery consumption | High-pitched | Low. | Medium. |
Video streaming via DLNA and third-party players
The Digital Living Network Alliance (DLNA) protocol is a standard for sharing multimedia content between devices on the same network, and if your TV doesn’t support Miracast or you want to play a specific format video file, this method is the most reliable.
To implement, you’ll need a third-party video player on your smartphone, such as VLC for Android or MX Player. Open the video file in the player, click on the broadcast icon (usually looks like a rectangle with waves in the corner), and select your TV from the list of available renderers.
The TV will get a stream of data and start decoding, which is great for watching movies in high bitrate, because many native galleries of phones can not correctly transmit 5.1 sound or subtitles through standard broadcast media.
What if there is no sound in the broadcast?
In some cases, you may need to manually adjust the resolution. If the picture twitches, try to lower the output quality or bitrate in the player settings, and also make sure that the TV does not turn on Eco mode, which can limit network activity.
Solving frequent connection problems and errors
Despite the simplicity of the technology, users can encounter a variety of errors, one of the most common is that the phone sees the Wi-Fi network but does not see the TV, often due to customer isolation settings on the router or the use of a guest Wi-Fi network, which prohibits the exchange of data between devices.
If you have a connection, but the image quality is low (pixelation, delays), try to bring the router closer to the TV and phone. To broadcast video in 4K requires a stable speed of at least 25-30 Mbps. Using the 2.4 GHz band in apartment buildings with noisy ether often leads to unstable work.
⚠️ Warning: Antivirus apps or firewalls on a smartphone can block ports needed to detect devices on a local network.
It is also worth checking the date and time.
