Owners of modern technology often wonder how to make the most of their gadgets, especially when it comes to multimedia. Broadcasting a smartphone screen on a large display allows you to turn an ordinary evening into a theater where you can watch movies, photos or play games on the full wall. For users of the Xiaomi ecosystem, this process is made as simple as possible thanks to the deep integration of MIUI software and the Android TV platform, which is used in most modern models of the brand’s TVs.
There are several proven methods of synchronizing devices, each with its own advantages and use cases. Wireless technologies such as Miracast and Google Cast provide convenience and no unnecessary wires, which is ideal for watching videos from streaming services or showing presentations. However, wired connection via HDMI remains the leader in signal stability and no delays, which is critical for gamers or when watching high-bit content.
In this article, we will take a look at all the available methods, help set up a connection and solve the typical problems that users face when trying to display an image. You will learn about the nuances of the built-in Xiaomi functions, the features of third-party applications and the requirements for network equipment for high-quality data transfer.
Device Preparation and Wi-Fi Network Requirements
Before you start setting up your broadcast, you need to make sure that both your smartphone and Xiaomi Mi TV are ready to interact. A fundamental requirement for most wireless methods is to find gadgets on the same local network. This means that both the phone and TV must be connected to the same router, preferably at 5 GHz, which provides higher bandwidth.
Note the software version. On the TV, it is recommended to upgrade the Android TV system or PatchWall shell to the latest available version through the settings menu. On the smartphone, you should also check for updates for MIUI and system components of Google Play Services, as they are responsible for the multimedia transfer protocols.
⚠️ Note: If your router supports the division of bands into separate SSID (for example,"Home_2.4G" and"Home_5G"), Make sure that both devices are connected to the network. 5 Mixed connection (one device per device) 2.4, elsewhere 5) In some models of routers, it can block the detection of devices with each other due to the peculiarities of isolating customers.
It’s also worth checking whether the DLNA or Media Server feature is enabled in your TV settings, although it’s often the default on current Xiaomi models. For wired connectivity, you’ll need a quality HDMI cable version 2.0 or higher if you plan to stream content in 4K resolution at 60Hz.
Use of the built-in Translation function in MIUI
The fastest and most native way to bring the screen of a Xiaomi phone to a TV of the same brand is to use the system function "Translation". This method is based on the Miracast protocol and does not require the installation of additional software. To start, you need to unlock the smartphone and lower the notification curtain down to open the control center.
In the list of fast switches, find an icon called Translation (sometimes called Cast or Wireless Monitor). If the icon is not visible, click the edit button (usually a pencil icon or three dots) and drag the desired item to the active panel. Once activated, the system will automatically search for available devices on the network.
On the screen of the Xiaomi Mi TV, you may receive a request for confirmation of connection. You will need to take the remote control and select "Allow" or "Confirm" in the window that appears. From now on, the image from the smartphone screen will be duplicated on the large display in real time.
☑️ Pre-broadcast checks
It is important to note that when using this method, the phone screen may go out to save power, but the broadcast will continue. However, some copyrighted applications (such as Netflix or iTunes) may show a black screen instead of a video due to HDCP policy. In such cases, it is better to use the built-in Translation button inside the video player itself.
Chromecast Technology and Google Home Apps
Because Xiaomi TVs are powered by Android TV, they have built-in support for Google Cast (Chromecast) technology, which allows you to not just duplicate the screen, but stream content directly from apps, which reduces the load on the smartphone battery and provides higher picture quality.
Install the Google Home app from the Play Market store on your smartphone if it is not already installed. Upon logging into your Google account, the app will automatically detect your Xiaomi Mi TV in the list of available devices. Click on the TV icon to open the control panel.
At the bottom of the device control screen, you'll see the "Cast my screen" button, and clicking on it will start the mirroring process of the entire smartphone interface, which has the advantage of being very stable and supporting a wide range of codecs.
| Parameter | Miracast (MIUI Translation) | Google Cast (Chromecast) | HDMI Cable |
|---|---|---|---|
| Delay. | Medium | Low (for video) | Absent. |
| Quality. | Depends on Wi-Fi. | Up to 4K HDR | Up to 4K/8K |
| Battery consumption | High-pitched | Medium. | Charging (at USB-C) |
| DRM protection | Frequent lockdowns | Supported | Supported |
If you use Google Chrome on your phone, you can also stream a tab or the entire screen through a three-dot menu by selecting Translate. This is a convenient way to show a web page or document on a large screen without installing any unnecessary apps.
What to do if the TV is not visible on Google Home?
Connecting via HDMI adapter
For tasks that require maximum reliability, such as gaming with a controller or presenting an important report, it is best to use a wired connection. USB Type-C often supports video output through standard MHL Or DisplayPort Alt Mode. You'll need a special adapter. USB-C to HDMI.
Connect the adapter to the smartphone charging connector, then connect it with an HDMI cable to the TV. Switch the signal source on the TV to the appropriate port (for example, HDMI 1 or HDMI 2). Unlike wireless methods, you do not need a Wi-Fi network, and the image will appear instantly.
Some phone models, especially the budget Redmi series or older flagships, may not support video output through the charging port. In this case, the system will give an error message or simply charge without transmitting an image. For such devices, there are special docks with DisplayLink support that transmit video stream through software compression, but they require the installation of a separate driver.
⚠️ Note: When using cheap adapters, you may experience dissynchronization of sound and video or no image in the video. 4K. Use certified cables no longer than 2 meters long to guarantee high-resolution signal transmission.
The advantage of the wired method is that the phone does not discharge, but can be charged if the adapter has an additional port to connect the power supply, which allows you to play heavy games for hours without fear of draining the battery.
Broadcasting through third-party applications
If standard methods don’t work or the functionality isn’t enough, third-party solutions come to the rescue. One of the most popular apps is AirScreen, which is installed directly on a Xiaomi Mi TV through the Google Play Store app store on a TV.
Once AirScreen is installed and launched on TV, the app emulates an AirPlay, Google Cast or Miracast receiver. On the phone, simply select the device found from the broadcast menu, a solution that often helps when Xiaomi's built-in protocols conflict with certain router models.
Another option is to use the LocalCast or BubbleUPnP app on your smartphone, which specializes in transferring media files (video, photos, music) over the DLNA protocol, so you pick a file in the phone gallery, click the "Cast" button, and select your TV.
💡
To view high quality video through DLNA, make sure the video file is in the phone’s memory and not in the cloud, as dual buffering (cloud-phone-TV) can cause delays.
It’s worth remembering that free versions of such apps often contain ads that can overlap part of the screen. For ongoing use, it’s wise to consider buying a premium version or using open source counterparts.
Elimination and delay of sound
One of the most common problems is the desynchronization of audio and video streams, where actors' lips are not moving in the rhythm of their voice. This often happens when the Wi-Fi channel is overloaded. To solve the problem, try closing background apps on your smartphone that may consume traffic, or moving the router closer to the viewing area.
If the image is interrupted or low resolution, check the resolution settings in the Translation menu on your phone. Decreasing the quality from 1080p to 720p can significantly improve the smoothness of the picture on weak networks. Also make sure that the TV turns off aggressive screen energy saving modes that can interfere with the processing of the incoming signal.
In cases where there is no sound at all, check the audio output settings. Sometimes the system tries to output the sound to the phone speaker by default, even if the video is on TV. In the Android sound control panel, select the output device "TV" or "Bluetooth device" (if the sound is transmitted separately).
💡
The stability of the wireless connection depends on the load of the air. In apartment buildings, switching the router to a less busy Wi-Fi channel can solve 90% of problems with image jerks.
