Modern Xiaomi and Redmi smartphones have powerful screens, but to view content in high quality or show photos of a large company, their diagonal is often lacking. In such situations, the screen duplication feature comes to the rescue, allowing you to broadcast an image from your smartphone to a large TV display. This process, known as screencasting or mirroring, turns any modern Smart TV into a multimedia center for your gadget.
Owners of Android devices, particularly the MIUI shell or the new HyperOS, have several built-in tools to do this. You don't have to buy expensive consoles if your TV supports wireless standards. You just need to make sure that both devices are on the same LAN and choose the right connection method.
There are many nuances that depend on the model of the TV and the version of the phone's operating system: some methods allow you to control content directly from the screen of the smartphone, others turn the phone into a remote control, and understanding the differences between transmission protocols will help you avoid delays and desynchronization of sound.
⚠️ Attention: The quality of wireless broadcasting is directly dependent on the speed and stability of your Wi-Fi router. If the video twitches, try to bring the router closer to the TV or use a cable connection.
Use of the built-in Translation function in MIUI
The easiest and fastest way to do this without installing third-party software is to use the Translation system function, which is deeply integrated into Xiaomi smartphones and runs on the Miracast protocol, which allows you to duplicate the screen one-to-one, which is ideal for displaying presentations, game menus or navigating the file system.
To activate this option, you need to open the control panel (curtain) and find the corresponding icon. If it is not visible, click on the pencil or edit button in the corner of the menu to add a shortcut. Once turned on, you will start searching for available devices within the range of the wireless network.
- 📱 Open the “curtain” of the swipe notifications from top to bottom.
- 🔍 Find and click the Translation icon (or Wireless Monitor»).
- 📺 Select your TV from the list of found devices.
- ✅ Confirm the connection on the TV screen if you receive a request.
Importantly, some older TVs may not support Miracast natively, in which case the smartphone will offer to install a special app on the TV, which will act as a receiver of the signal, and it is worth considering that when the screen is actively duplicated, the smartphone battery discharges faster than usual due to the high load on the Wi-Fi module and processor.
☑️ Checking before connection
Broadcast via the Mi TV app (for Xiaomi and Android TVs)
If your TV is also made by Xiaomi or runs on Android TV, the best solution is to use the proprietary Mi TV app (formerly known as Mi Remote), which provides a more stable connection and often allows you to transmit sound with less latency than a standard Miracast.
To get started, you need to download the app from Google Play or GetApps if it's not pre-installed. Once it's launched, it automatically scans the network and finds compatible devices. A unique feature of this method is that it can use the phone as a full touchpad to control the TV interface.
The connection process is as simple as possible and requires minimal user intervention. However, if the devices do not detect each other, check the settings of the router firewall. Sometimes network screens block the ports necessary for local communication between gadgets.
What to do if the app can’t see the TV?
The Mi TV app also allows you to broadcast not only the entire screen, but also individual media files from the gallery, which is convenient when you need to show a photo album without being distracted by messenger notifications, which can pop up when the screen is fully mirrored.
Using Google Chromecast built-in technology
Most TVs, regardless of brand, have built-in Chromecast support, which allows you to stream content directly from apps like YouTube, Netflix or Google Chrome without having to duplicate the entire screen of your smartphone, in which case the phone acts as a remote control, and video streams directly from the Internet to the TV.
To use this method, look for a typical rectangle icon with waves in the corner in an app (e.g. YouTube) and click on it will open a list of available devices, which is considered the most energy-efficient method, since the smartphone processor does not encode the video stream in real time.
| Parameter | Miracast (Translation) | Chromecast (Translation from the app) |
|---|---|---|
| Processor booting | Tall. | Low. |
| Battery consumption | Fast. | Minimum |
| Image quality | Depends on the power of the phone. | Maximum (up to 4K HDR) |
| Management | Phone from phone. | You can use it as a remote. |
Remember, Chromecast requires a stable Internet connection on the TV itself. If the router distributes the network at 2.4 GHz, you may slow down when playing high-resolution video. It is recommended to use the 5 GHz band to transmit heavy video content.
💡
For the best picture quality when using Chromecast, make sure that both the phone and TV are connected to the same frequency network (both at 2.4 GHz or both at 5 GHz), even if the network names (SSID) are the same.
Broadcasting through the Google Chrome browser
If your TV doesn’t have Miracast built-in support, but you have an HDMI connector and the ability to install apps (or Android), you can use the Google Chrome browser on your smartphone or PC as an intermediary. However, if you’re talking about live streaming from an Android phone, most often you’re talking about the Translation feature inside the Chrome browser itself on your mobile device.
Opening your browser, click on the three-dot menu and select Translate. The system will suggest selecting a device, and the peculiarity of this method is that it allows you to display not only the browser tabs, but also the entire screen of the smartphone, if you select the appropriate option at the source.
This method is especially useful for viewing websites that do not have an optimized mobile app with a Cast button, or for displaying documents opened in cloud storage via a browser.
⚠️ Note: When broadcasting the browser tab, the sound may not be transmitted to the TV automatically. Check the tab settings or use system volume to switch audio output.
Connection via USB-C to HDMI cable
For users who are critically important to the stability of the connection and the absence of any delays (for example, gamers or designers), the optimal solution will be a wired connection. This requires a special adapter USB-C to HDMI. It is important to understand that not all Xiaomi smartphones support the output of images through the charging port.
The technology that allows video to be transmitted over cable is called MHL or DisplayPort Alt Mode. Xiaomi's flagship models (Mi and Xiaomi numbered series) often have this support, while the budget Redmi and Poco models can be limited only to data transfer and charging.Be sure to check the specification of your model on the official website before buying an adapter.
- 🔌 Connect the adapter. USB-C to HDMI smartphone-wise.
- 📺 Connect the adapter and TV with a cable HDMI.
- 📺 Switch the signal source on the TV (button) Input/Source) port-to-port HDMI.
- 📱 The image should appear automatically; if not, check the screen settings under Connections».
The advantage of the wired method is that there is no dependence on the quality of the Wi-Fi network and no input lag. In addition, the smartphone in this mode often continues to charge if the adapter has an additional port for power.
Solutions and Connection Problems
Despite the simplicity of the technology, users often face situations where the phone can't see the TV or the connection is constantly broken.One of the most common reasons is the use of different Wi-Fi frequency bands. If the router broadcasts two networks with the same name but different frequency, the devices may not see each other due to client isolation settings.
Problems can also arise from outdated software: MIUI firmware and TV systems are regularly updated to fix protocol errors. If the wireless connection is unstable, try updating the software on both devices to the latest available version.
In rare cases, resetting network settings on a smartphone helps, which will delete stored Wi-Fi passwords and Bluetooth settings, but often solves problems with the malfunction of network modules, and after reset, you will need to re-enter the password from the home network.
