How to Replay the Screen from Android to Xiaomi TV

Today’s users rarely limit themselves to watching content on their smartphone screen, especially when it comes to watching movies, vacation photos or presentations. The huge potential of Android devices is only truly revealed when displaying images on the big screen, and here come the help of Xiaomi Mi TVs or Mi Box consoles. Wireless video transmission technology allows you to turn any gadget into a powerful multimedia center in seconds.

The process of syncing devices can seem difficult to a beginner due to the abundance of protocols and titles such as Miracast, Chromecast or DLNA. However, in the Xiaomi ecosystem, this process is as simple as possible and often does not require the installation of additional software. In this article, we will detail all the available ways to connect so that you can enjoy content in high resolution without delays and artifacts.

Preparation of equipment and Wi-Fi network

The first and most critical condition for successful broadcasting is to be both devices on the same local network. Make sure your smartphone and Xiaomi TV are connected to the same router, and it is advisable to use 5 GHz frequency to ensure high channel bandwidth. When using the 2.4 GHz band, image delays or sound desynchronization are possible, especially when watching video in 4K.

You also need to check the operating system version on both devices. On Xiaomi TVs with PatchWall shell or pure Android TV, image transfer functions are built in by default, but may require activation in the menu. On a smartphone, the function can be called differently depending on the manufacturer: Translation, Smart View, Wireless Monitor or Screen Replay.

⚠️ Note: If your router supports Smart Connect, when 2.4 GHz and 5 GHz share the same name, there may be visibility conflicts.

Built-in Cast on Android and PatchWall

The easiest way to avoid third-party software is to use the native operating system function. In most modern smartphones based on Android 9 and above, this option is hidden in the notification curtain or in the connection settings menu. On Xiaomi TVs with a PatchWall shell, you need to make sure that the appropriate signal receiver is running.

To start the process, look for the Wireless Display app or Mi Play app on your TV (depending on region and firmware version). Once the app is opened, the device name and the connection waiting status will appear on your TV screen. Now pick up your smartphone and lower the upper curtain of the Quick Action menu.

Find an icon called Translation, Projection, or a wave rectangle icon. Once you click, your phone will search for available devices on the network. When your Xiaomi TV appears on the list, click on it to pair. A connection confirmation request may appear on your TV screen, which you need to agree with the remote.

It is worth noting that the quality of the transmission depends on the wireless network loading. If you are broadcasting heavy files or games, it is better to disable downloads on other devices.The Miracast protocol used in this method creates a direct connection, which minimizes delays, but can consume more battery power of the smartphone.

Use of the Google Home app

If the built-in tools don’t work or your TV runs on Android TV without specific shells, the ideal solution is the official Google Home app. This is a universal smart home management tool that also does a great job with the Chromecast built-in function. You can download the application from the Google Play store if it is not preinstalled.

Once you install and log in to your Google account, the app will automatically scan the network and find available output devices. From the list of devices, select your Xiaomi TV. From the control menu at the bottom of the screen, you will see the Cast my screen button. Press it to start duplication.

The advantage of using the Google ecosystem is that you can use the stable connection and support high resolution, and you can control volume through Google Home, and even use your smartphone as a touchpad to navigate the TV interface, which is especially useful if the remote is lost or its batteries are dead.

Broadcasting via Chrome and YouTube

Often, users don’t need to display the entire smartphone interface on the big screen, but specific content: a web page, document or video. Google Chrome is ideal for web surfing. Open the desired page, click on the menu of three dots in the corner and select Translate.

Youtube is a special app, and unlike full screen broadcasting, it uses direct play technology, you click the broadcast icon (a rectangle with a Wi-Fi signal) in the app itself on the phone, you choose a TV, and the video starts playing directly on the TV over the Internet.

This approach saves battery life on a smartphone, as it acts as a remote control, not a source of video streaming, and is the only way to get a native 4K HDR image without compression, since the TV itself decodes the video stream using its powerful processors, not the resources of the phone.

Third-party applications for enhanced capabilities

In situations where standard protocols are not supported by the TV (e.g. older models without Smart TVs) or specific functionality is required, third-party solutions come to the rescue. One of the most popular applications is AirScreen or ApowerMirror, which must be installed directly on the TV through the Google Play Store on Android TV.

Once you install the app on TV, follow the instructions on the screen to launch the reception server. On your smartphone, you may need to install a companion app or simply use the standard Translation feature, which now sees the virtual receiver created by the program. Such applications often support the AirPlay protocol, which allows you to broadcast the screen even from Apple devices to Xiaomi TVs.

⚠️ Note: Free versions of third-party apps often contain ads and may have session time or image quality restrictions.For ongoing use, consider buying a premium version or using open-source counterparts.

💡

If you use a third-party app for games, turn on the phone mode "Do not disturb" so that notifications do not overlap the gameplay on the big screen.

Another option is to use DLNA media servers like BubbleUPnP or Xiaomi Mi Video, in which case you don't duplicate the screen, but send a file (video, photos, music) to play back to the TV, which is a great way to watch a movie downloaded to your phone's memory without wasting Internet traffic.

Connecting via HDMI adapter

For gamers or situations where wireless network is unstable, the best choice is wired connection. You will need a special USB-C to HDMI adapter with video output. Note that not all Xiaomi smartphones support image output via the charging port; this feature is mainly the flagship models of the Mi and Xiaomi series with Snapdragon 800-series processors.

Connect the adapter to your smartphone, then connect it with an HDMI cable to your TV. Switch the TV signal source to the appropriate port (for example, HDMI 1). The image will appear automatically. The phone settings may display a menu for choosing the mode of operation: "Mirror" or "Extended desktop" (similar to Desktop Mode).

Using the cable ensures no delays (input lag), which is critical for dynamic games. In addition, when wired, the smartphone can simultaneously charge if the adapter has an additional USB port for power, which turns the bundle of the smartphone and TV into a full-fledged multimedia station.

💡

Wired connectivity is the only way to guarantee zero signal latency, which is indispensable for cloud gaming and competitive online games on the big screen.

Addressing problems and delays

Despite the simplicity of the technology, users may face problems such as black screen instead of image, desynchronization of sound or periodic connection breaks. The first step in diagnosis should always be to restart the router and both devices. Often the problem lies in the overflow of cache DNS conflict IP-local-network addresses.

If the image is twitching or low resolution, try to reduce the load on the Wi-Fi channel. Turn off computer torrents or other streaming. Also check if the router is not using a speed limit for certain devices (QoS), which can prioritize other traffic at the expense of broadcasting.

In conclusion, the choice of broadcast method depends on your specific tasks: there are enough built-in tools for viewing photos and videos from the gallery, for YouTube it is better to use a native Cast, and for games, an HDMI cable is preferable. Xiaomi ecosystem provides flexible tools for any use case.
