How to Demonstrate a Screen from Your Phone to a Xiaomi TV

Xiaomi’s modern smartphones and TVs create a single ecosystem that makes multimedia use much easier. The ability to instantly display images from a small screen to a large diagonal is becoming the standard for watching movies, photos or presentations. Users often look for ways to make a screen demonstration from phone to TV xiomi to enjoy content in high quality without unnecessary wires.

In this article, we will take a look at all the available broadcasting methods, from built-in MIUI system functions to third-party applications. You will learn about the nuances of Wi-Fi connectivity, the features of Miracast and Chromecast protocols, and how to solve typical connection problems.

Before you start setting up, make sure that both your smartphone and your TV are on the same LAN, a key condition for wireless protocols to work smoothly. If a router is giving away a network at 2.4 GHz and 5 GHz, try to connect your gadgets to one of them, preferably a faster 5 GHz, to minimize the lag.

Preparatory stage and check of compatibility of devices

The first step is to check the software version of the operating system on your Xiaomi TV. The wireless image transfer feature is built into the PatchWall or Android TV shell, but on older models, you may need to update your firmware. Go to the settings menu and find the About TV → System Update section to see if the software is up to date.

It is also important to check whether the TV is enabled with Miracast protocol or Wireless Monitor. On some Xiaomi TV models, you need to run a special application called “Mi Screen Cast” or “Wireless Display” to activate the signal reception mode, which is usually located in the application folder or on the home screen. Without active standby, the TV will not be visible to the phone.

Note the model of your smartphone. Xiaomi devices with MIUI shells have native support for broadcast technology, which eliminates the need to install additional software. However, if you use a phone from another manufacturer, the process may be slightly different, although the basic principles remain the same throughout the Android ecosystem.

⚠️ Warning: Make sure the router has disabled the function «AP Isolation, if any, prevents devices connected to the same Wi-Fi network from communicating with each other, making it impossible to detect the TV.

Use of the built-in Translation function in MIUI

The easiest and fastest way to do a screen demonstration from your phone to your xiomi TV is to use a standard system tool. In Xiaomi smartphones, this feature is called Translation and hidden in the control menu. To call it, you need to unlock the phone and swipe from top to bottom to open the notification curtain.

Find a button called Translation among the icons. If it's not on the first page, click on the edit button (usually a pencil icon or three dots) and add a widget from the list of available ones. Once activated, the system will start looking for compatible devices on the local network. When your Xiaomi TV name appears on the screen, tap it to connect.

Once successfully connected, the image from the phone is fully duplicated on the TV screen, in which the orientation of the screen automatically changes when you turn the smartphone, which is convenient for watching video in landscape mode or showing photos in portrait orientation. To control the process, you can use a pop-up menu on the phone, where you can stop the broadcast or change the image quality.

It's worth noting that when using the built-in stream, the phone can get a little warmer, because the process of encoding the video stream requires CPU resources. This is normal, but if you plan a long demonstration, it's better to put the device on charge or provide a good heat sink.

Broadcasting through the Google Home app

If the standard method doesn’t work for any reason or you want to access advanced management features, the Google Home app is a great solution, which is especially effective for Xiaomi TVs running a clean Android TV operating system, as it uses the Chromecast built-in protocol.

To get started, download and install the Google Home app from the Play Market Store. Once installed, open the program and log in to your Google account. The app will automatically scan the network and find available devices. In the list of devices, find your Xiaomi TV and click on it.

In the TV control menu that opens, select the option “Cast my screen” and the system will alert you that all actions, including notifications and personal data, will be displayed on the screen. Confirm the action by clicking “Start now”.

⚠️ Attention: When streaming through Google Home, the default sound can go through the phone's speaker, not the TV. To fix this, tap the speaker icon in the Google Home app and switch the audio output to the TV.

The advantage of this method is the high stability of the connection and the ability to stream content from applications that do not have a built-in “Cast” button.In addition, Google Home allows you to control the volume and stop the broadcast directly from the lock screen or through the widget.

Connection with Mi Remote and Mi Home

Xiaomi’s ecosystem offers its own tools for device integration, but it’s important to understand their limitations: Mi Remote and Mi Home are primarily designed to manage a smart home and use the phone as a remote control, rather than a screen mirroring.

However, in some regions and firmware versions, the Mi Video (Mi Video) app has a built-in feature. DLNA-You can open the video file in this player, press the button «TV» Or "Cast" in the corner of the screen and choose your Xiaomi TV, in which case you'll only be broadcasting the video file, not the entire screen of the smartphone, which saves battery life.

If you’re using a Xiaomi smart home, make sure the TV is added to the Mi Home app.This will allow you to create automation, such as turning on the TV when you start a stream from your phone, although the direct “mirror” feature here is implemented through the Android system protocols described above.

Wired connection via HDMI adapter

For users who want maximum image quality without compression and delay, wired connectivity is the ideal solution. Since modern Xiaomi smartphones often lack a mini-HDMI port, you will need a special USB Type-C to HDMI adapter.

Connect the adapter to the phone's charging connector and the adapter itself to an HDMI cable that goes to the TV. The TV automatically detects a new signal source, and you only have to select the appropriate input (Input) on the TV's remote, such as HDMI 1 or HDMI 2.

This method allows you to transmit an image in 4K resolution at 60 Hz if your phone and TV support HDMI 2.0 and higher, and when wired, the phone continues to charge (if the adapter has a charging port), which is critical for long sessions of work or games.

It should be borne in mind that not all budget models of Xiaomi smartphones support video output via a USB port. Usually this feature has the flagship series (Mi, Xiaomi Pro) and some models of the Redmi Note series with support for DisplayPort Alt Mode technology.

💡

Use an HDMI cable no longer than 3 meters long to maintain a stable 4K signal. Too long low-quality cables can cause interference or “snow” on the screen.

Solving common problems and errors

Despite the ease of setting up, users may encounter difficulties. One of the most common problems is that the phone can't see the TV, in which case check if the router's firewall has blocked local data exchange, and rebooting both devices also helps: turn off and turn on the TV and phone again.

If there is an image but the sound is missing or is coming with desynchronization, try changing the audio output settings in the application through which the broadcast is being broadcasted. In some cases, reducing the quality of the transmitted video in the settings of the broadcast application itself helps to reduce the load on the communication channel.

Another problem can be an inverted image or an incorrect aspect ratio, which is addressed through the phone's settings menu in the Screen section or through the zoom settings in the TV's menu itself (often the "Aspect" or "Format" button on the remote).

⚠️ Note: When connecting through HDMI The adapter may require external power. If the image is lost or flickering, connect the charger to the USB-port.

💡

The stability of wireless broadcasting is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air.
