Xiaomi’s current smartphones have high-resolution screens that often outperform many budget TVs in terms of image quality. However, to watch family videos, photos or games on the big screen, you need to display pictures. Wi-Fi is the most convenient and technological way to accomplish this task, eliminating confusion with wires.
The process of syncing gadget and TV is based on wireless media protocols such as Miracast or DLNA. In the ecosystem of MIUI and the new HyperOS, these functions are deeply integrated, but their activation may vary depending on the model of your TV. Below we will discuss all available methods, from embedded tools to third-party applications.
It is critical to successfully connect both devices on the same LAN, which means that the router must properly distribute the signal, and the smartphone and TV must be connected to the same SSID (network name). If you have a dual-band router, make sure that the gadgets are connected to the same frequency, although modern routers usually handle traffic correctly between the 2.4 GHz and 5 GHz bands.
Compatibility check and equipment preparation
Before you start setting up, you need to make sure your TV supports Smart TV technology or has a built-in Wi-Fi module. Older models of “boxes” without smart features will require the use of additional devices, such as Chromecast or Apple TV, which will act as intermediaries.
Owners of Xiaomi equipment are in a good position, as the Android operating system on which MIUI is based has native support for most broadcast standards.
⚠️ Warning: Make sure your router doesn’t have customer isolation enabled (AP Isolation, which prevents devices on the same network from seeing each other.
Check the software version on your smartphone. For stable operation of the Translation function, it is advisable to have an updated firmware. Go to Settings → About the phone and check for system updates.
💡
If the TV can’t see the phone, try temporarily turning off mobile internet (3G/4G) on your smartphone so that all traffic goes exclusively through the Wi-Fi module.
Use of the built-in Translation function in MIUI
The easiest and fastest way to connect Xiaomi to a TV is to use a standard system application, which can be called "Translation", "Wireless Monitor" or "Cast" in different versions of the shell. This method implements the Miracast protocol, which allows you to duplicate the screen of a smartphone in real time.
To start the process, lower the notification curtain and find the Translation icon. If it is not on the control panel's home screen, click on a pencil or edit button and drag the icon to the active area. Once activated, the system will start searching for available devices within network range.
A connection request may appear on a TV screen, and some Samsung, LG, or Sony models require a remote control to confirm access, and when the request is received, the image from the phone will appear on the big screen.
- 📱 Open the control center and find the "Translation" icon".
- 📺 Make sure that Wi-Fi Display is included in the TV menu.
- 🔗 Select the name of your TV from the list of devices found.
- ✅ Confirm the connection on the TV screen if a request appears.
It’s important to understand that when using this method, the smartphone screen doesn’t go out.You can control playback directly from your phone, but notifications coming to Xiaomi will also be displayed on your TV, which can be uncomfortable when watching movies.
Broadcasting through the Google Home app
If the feature is unstable or your TV supports Chromecast built-in, the best solution is the official Google Home app, which is available in the Google Play Market and pre-installed on many Xiaomi smartphones.
This method is considered more stable because it uses Google’s infrastructure to buffer the flow, and is ideal for streaming videos from YouTube, Netflix or other supported services, allowing the phone to be used as a remote rather than just a screen mirror.
Once you install the app, open it and find your TV icon in the device list. Click on it, then select the "Cast my screen" button. The system will alert you that all the contents of the screen will be broadcast.
⚠️ Note: When streaming through Google Home, battery consumption increases significantly, as the Wi-Fi module operates in a constant high load mode.
The advantage of this method is the ability to broadcast tabs in the Chrome browser. You can open the site with a video on your phone and display it on the TV by selecting the option "Translate" in the browser menu.

Xiaomi TV Assistant Solution
For users who want to get more functionality, Xiaomi has developed the Xiaomi TV Assistant app (formerly known as Mi Remote or part of the ecosystem utilities), which allows you not only to broadcast media files, but also to use your smartphone as a full-fledged touchpad control panel.
The app is especially useful if standard methods can’t find the TV or are delayed, it supports transferring photos, videos and music from the internal memory of the smartphone, and the interface is intuitive and adapted to the logic of MIUI.
To get started, launch the app and press the add-on button, scan the network and suggest a list of compatible TVs, and then pair you up and access the media server menu.
- 🎬 Support for a wide range of video formats without conversion.
- 🎮 Possibility to use a phone gyroscope to control games on TV.
- 📂 Easy navigation on the file system of the smartphone.
- 🔋 Optimized energy saving mode during long-term broadcast.
Xiaomi TV Assistant works best with Mi TVs, but thanks to the support of the protocol, DLNA also works well with other brands such as Philips or TCL.
Connecting to a regular TV through adapters
Owners of conventional TVs without Smart TV can also enjoy content from their Xiaomi over Wi-Fi. This requires purchasing a special adapter that connects to the HDMI port of the TV and creates an access point or connects to your router.
The most popular solutions are Google Chromecast, Amazon Fire TV Sticks, or universal Miracast whistles, these devices take on the role of a signal receiver, broadcasting the image to the image. HDMI-television-inlet.
The setup process in this case is reduced to switching the source of the signal (Source) on the TV to the corresponding HDMI port. Next, the actions are repeated by the algorithm for the Smart TV: search for the device in the “Translation” menu on the smartphone and the connection.
| Adapter type | Protocol | Stability | Price. |
|---|---|---|---|
| Google Chromecast | Chromecast / Wi-Fi | Tall. | Medium |
| Miracast Dongle | Miracast / DLNA | Medium | Low. |
| Apple TV | AirPlay 2 | Very high. | Tall. |
| Android Box | All protocols | Tall. | Medium |
Using external adapters often solves the problems with lags and delays that can be observed when connecting directly to the built-in modules of old Smart TVs. In addition, it allows you to update the functionality of the old TV, adding support for modern codecs.

Troubleshooting and troubleshooting
Despite the simplicity of the technology, users can face problems, and often the phone simply "can't see" the TV, in which case the first step is to check whether the router's firewall has blocked the connection between devices.
Another common problem is audio and video desynchronization or poor picture quality, which indicates Wi-Fi congestion. If there are many neighbourhood networks running nearby, try switching your router to a less busy channel or using the 5GHz band.
It’s also worth checking the date and time settings, and if your smartphone and TV have more than a few minutes of different time, security protocols can block the connection.
⚠️ Warning: Antivirus apps on your phone may block your local network connection. Try temporarily disabling protection or adding a TV to exceptions.
If nothing works, reset your network settings on Xiaomi. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This will bring the network modules back to factory settings.
💡
The stability of the connection depends on the power of the router signal and the absence of physical obstacles between devices.
