Modern technology allows you to turn any compatible TV into a multimedia center for your smartphone. Owners of Xiaomi and Redmi devices often wonder how to quickly and wirelessly broadcast content from the display of the gadget to the big screen. This can be necessary for watching movies, showing presentations or running mobile games in high resolution. The functionality of the MIUI system provides several built-in tools for this task.
The main method of image transmission is based on Wireless Display technology, which is built into the manufacturer's shell, which allows you to create a direct connection between devices located on the same local network. However, there are nuances that depend on the model of the TV: whether it supports the Miracast protocol natively or requires the installation of additional software. Understanding these differences will help to avoid connection problems and signal delays.
In this article, we will take a look at all the current ways of connecting, from standard system functions to the use of specialized cables, learn how to adjust the transmission quality and eliminate possible lags, and consider scenarios where standard methods do not work, and alternative solutions will be required.
Use of the built-in function Wireless monitor
The most common and convenient way is to use the system utility, which is built into the MIUI shell by default, called the Wireless Monitor (or Translation in new versions). To work correctly, both devices must be connected to the same Wi-Fi network. If the router distributes at 5 GHz, the data transfer speed will be much higher, which will reduce image latency.
The activation process begins with the opening of the control center. On most Xiaomi smartphones, you need to swipe down from the top right corner of the screen. In the menu that appears, the icon may be called "Translation" or have an icon with arrows on the screen. If you can't see it right away, try swiping left or clicking on three dots to edit the list of widgets.
Once the search is launched, the system will start scanning available devices within range. On a Xiaomi Mi TV or Android TV, you may need to confirm your connection in a pop-up window. Sometimes the TV screen displays the code that you need to enter on your smartphone for security.
It is important to consider that when you are actively connected, the smartphone screen may go out to save energy, but the broadcast will continue. If the image is interrupted, check if the phone is power saving mode, which limits the background activity of the Wi-Fi module.
💡
To reduce latency when playing, turn off guest network mode on the router and make sure that both devices are connected to the main 5 GHz network.
Broadcasting through the Google Home app
If MIUI's built-in tools don't see your TV for some reason, the official Google Home app is a great alternative, especially for TVs running Android TV or Chromecast, a universal smart home management tool from Google.
To get started, download the app from the Google Play store and log in to your account. Once you open the program, click on the add-on button or select your TV from the list of available gadgets in the main menu.
The app's functionality allows you not only to duplicate the screen, but also to manage media. You can run a video in your Chrome browser or YouTube app and click on the "Translate" button by selecting the target device, which provides a more stable connection, as the stream is transmitted directly from the Internet to the TV, bypassing the phone's processor.
⚠️ Note: When using the Chromecast method, some applications may block the output of protected content (DRM) on external screens, displaying only a black screen with sound.
The advantage of this is that you can control multiple devices at once, so you can create a group of devices and display the image on multiple TVs in different rooms, but it requires a stable and fast Internet connection.
Set up Xiaomi TV to receive the signal
Before you try to connect your phone, you need to make sure that the TV is ready to receive the signal. In most modern Xiaomi and Redmi TV models, wireless support is built in by default. However, in some cases, the function needs to be activated manually through the system settings.
Go to the TV settings menu and find the partition associated with connections or network. The option you want to look for may be called "Wireless Monitor," "Miracast," "Screen Mirroring," or "Duplicate Screen." Make sure the switch is in the "On" position.
☑️ Checking the readiness of TV to connect
If the TV is powered by PatchWall (a Xiaomi branded shell), the feature is often available via the signal source menu. Press the source select button on the remote and select "Wireless Monitor." The screen will display a wait for the connection.
In rare cases, especially on older models or TVs with other OSes (like Tizen or WebOS, if they are not from Xiaomi), you may need to install a special application from the app store on the TV itself.
| Connection method | Required TV SOFTWARE | Delay (Latency) | Image quality |
|---|---|---|---|
| Built-in (MIUI) | Not required | Low. | High (up to 1080p/4K) |
| Google Home | Chromecast built-in | Medium | Adaptive. |
| HDMI cable | Not required | Absent. | Maximum. |
| Third-party annexes | APK installation | Tall. | Depends on the network. |
Connecting via HDMI adapter
When wireless connectivity is impossible due to poor signal or maximum quality without compression is required, wired connectivity comes to the rescue. Xiaomi smartphones with USB Type-C port require a special adapter (adapter) on HDMI. It is important that the phone port supports video transmission technology (MHL or DisplayPort Alt Mode).
The connection process is very simple: insert the adapter into the charging connector of the smartphone, and connect the adapter itself with a regular HDMI cable. The second end of the cable is inserted into the free port of the TV. Then on the TV remote, press the source selection button (Input) and specify the corresponding HDMI port number.
The image on the TV screen will appear automatically. Unlike wireless methods, it doesn't require network setup or pairing. The phone perceives the external display as a second monitor. It's ideal for games where every millisecond of response counts.
Which Xiaomi models support USB-C video output?
It is worth noting that when wired, the phone can quickly discharge, as the external module is actively powered. It is recommended to use an adapter with an additional port to connect the charger to simultaneously broadcast the image and charge the battery.
Use of third-party broadcasting applications
If standard methods don't work, third-party apps come to the rescue, and one of the most popular solutions is Web Video Caster or Cast to TV, which allows you to stream content from your browser or local files directly to your TV using DLNA or Chromecast technologies.
To run these programs, you need to install the app not only on your phone, but also the appropriate receiver on your TV (if it's not built in), and when you run, both devices will find each other on the LAN, you select the video file on your phone, and it starts playing on the TV screen.
The good thing about this method is that it's less demanding on the operating system version and often bypasses software locks, but free versions of these applications often contain ads, and the image quality may be inferior to the system translation due to additional stream transcoding.
⚠️ Note: When installing third-party APK-Be careful and download programs only from verified sources to avoid malware infection.
There are also remote control applications that allow you to use your phone as a remote and transmit an image at the same time, such as Mi Remote in conjunction with other ecosystem services.
Solving Connection and Delay Problems
A common problem with wireless broadcasting is the desynchronization of sound and image or periodic hangings, which almost always indicates a problem with the bandwidth of the communication channel, if the router is far away or congested with other devices, you can not achieve a stable picture.
Try rebooting your router, phone, and TV. Often, simply resetting the network module cache solves the invisibility problem of your devices. Also make sure that both devices are enabled with Bluetooth and geolocation — some versions of Android require this to detect nearby gadgets.
💡
The key to stable broadcasting is to use 5GHz and the minimum distance between the router and the receiving device.
If the image twitches, try lowering the output resolution in the broadcast settings (if such an option is available) or closing the background apps on the smartphone that consume traffic. In extreme cases, updating the TV firmware through Settings → About TV → System update can correct software errors.
