Modern Xiaomi smartphones have powerful screens, but watching movies in 4K or showing presentations often requires a large diagonal. Synchronizing a mobile device with a TV allows access to the media library on a large screen without loss of quality. This is convenient not only for entertainment, but also for work, allowing you to display the image from your phone to a monitor or TV panel.
The connection process depends on the type of TV you have, whether it supports Smart TV, whether it has a built-in Chromecast module, or whether you plan to use a wired connection. In this article, we’ll take a look at all the current methods, from wireless protocols to physical cables, so you can choose the best option for your situation.
It is important to understand that the stability of the connection depends on the quality of the Wi-Fi network and the version of the MIUI operating system. Some older TV models may require the installation of additional applications, while new devices work out of the box.
Preparation of devices and compatibility check
Before setting up, make sure both devices are ready to interact. The basic requirement for most wireless methods is to find a Xiaomi smartphone and a TV on the same local network. If a router is sending out a signal at 2.4 GHz and 5 GHz, make sure that the gadgets are connected to one of them, although modern routers often combine them into a single network.
Check the version of the operating system on your TV. Android TV and Google TV have most of the features built in by default. If you have Samsung or LG, you may need to update your TV firmware to support Miracast protocols. On your smartphone, you should also check for updates in Settings → About Phone.
⚠️ Note: If your router is configured with client device isolation (AP Isolation, the phone won't see the TV, a feature often enabled on guest networks for security, but blocks local data transmission.
Make sure that both devices are enabled with wireless communication modules. On TVs without Smart TVs, wireless synchronization is not possible without the use of external adapters such as Chromecast or Amazon Fire Stick. In this case, the setting is done through a companion application on the smartphone.
Broadcasting through the built-in function "Translation" (Cast)
The easiest way to sync Xiaomi with your TV is to use the system function "Translation" based on the Miracast protocol and does not require the installation of third-party software, which is ideal for screen cloning: everything that happens on the display of the smartphone is displayed on the TV in real time.
To start, open the control center (curtain) and find the icon "Translation" or "Cast." If the icon is not, you can add it through the editing menu of quick settings. Once turned on, the phone will start searching for available devices on the network. Select your TV from the list, and in a few seconds the image will appear on the big screen.
- 📺 Open the notification curtain on Xiaomi smartphone swipe from top to bottom.
- 🔍 Find and click the Translation button (sometimes hidden in the optional menu).
- 📡 Wait for your TV name to appear on the list of available devices.
- ✅ Click on the TV name to establish the connection.
Some TV models, especially Samsung and LG, may need to confirm the connection on the remote control.It is also worth noting that when using this method, the smartphone screen must be turned on, which affects battery autonomy.
💡
Miracast protocol broadcasts the image from the screen, so notifications and calls will be visible on the TV, if you do not turn on the Do Not Disturb mode.
Using Chromecast Technology and Google Home
If your TV is equipped with a built-in Chromecast or an Android TV Box is connected to it, the best solution is to use the Google ecosystem, which differs from Miracast in that it allows you to stream content directly from applications without straining the phone’s processor.
To manage the process, install the Google Home app from the Play Market, which allows you not only to broadcast the screen, but also to configure device groups and manage the smart home. Once installed, open the app, find your TV and click on the Translate screen button.
The advantage of this method is that it supports codecs and connectivity stability, so videos from YouTube or Netflix will play at the maximum quality that TV supports, even if the phone is used for other tasks at the time, which distinguishes the Chromecast from simple mirroring.
What is the difference between Cast and Miracast?
Wired connection via HDMI and adapters
When the wireless network is unstable or requires maximum image quality without compression, cable connection is used. Xiaomi smartphones with USB Type-C port require a special adapter (adapter) on HDMI. It is important that the phone port supports DisplayPort Alt Mode technology.
Not all Xiaomi models support image output via USB-C. Usually this feature has flagship series Mi and Xiaomi (for example, Mi 10, Mi 11, Xiaomi 13/14), as well as some models of the Black Shark series. Budget devices of the Redmi series are often deprived of this ability, and the adapter will not work.
The connection scheme is simple: the adapter is inserted into the charging connector of the smartphone, and a cable is connected to it. HDMI, When you switch the source of the signal to the TV (Source or Input button), the desktop of the phone will appear on the screen. 4K-content.
| Type of connection | Image quality | Delay (Latency) | Battery consumption |
|---|---|---|---|
| HDMI (Adapter) | Maximum (no compression) | Absent. | Charging from the grid. |
| Chromecast | High (up to 4K HDR) | Low. | Medium. |
| Miracast | Good (compression) | Medium | High-pitched |
💡
When wired through an HDMI adapter, the phone may not charge. Use adapters with an additional port to connect the charger.
Third-party synchronization applications
If the standard methods don’t work or the TV is older, third-party apps come to the rescue, and one of the most popular solutions is TV Assistant or Mi Remote (for IR-ported TV), as well as universal utilities like Web Video Caster.
The TV Assistant app is often pre-installed on Xiaomi smartphones, allowing not only control of the TV, but also broadcast photos and videos from the gallery, you need to install the server part on the TV (if it is on Android TV) or use built-in DLNA support.
For advanced users, there is an option to configure via ADB (Android Debug Bridge), but this requires the developer mode to be enabled. In the Settings → Menu, you need to press the MIUI version 7 times, then activate “Debugging by USB” in advanced settings.
⚠️ Note: Download the live streaming apps only from the official Google Play store or GetApps. APK-Files may contain malicious code that steals your local network data.
- 📺 AllCast – Allows you to send content to a variety of devices, including game consoles.
Solving Connection Problems
Often, users are faced with a situation where the phone does not see the TV. First of all, check whether the antivirus or firewall on the router blocks the local connection, and also helps to reboot both devices: turn off the TV from the socket for 10 seconds and restart the smartphone.
If there is an image but no audio, check the audio output settings in the app where the broadcast comes from. In some cases, you need to manually switch the output in the Bluetooth or HDMI settings of the TV. MIUI is characterized by a problem with energy saving, which "kills" the background broadcast process.
To avoid a communication breakdown, add Translation or Google Home to power saving exceptions. Go to Settings → Battery → Settings and select No Limits for the desired application. This ensures that the background services work smoothly.
