How to turn on the screen repeat on the Xiaomi TV: from smartphone to large display

Xiaomi’s modern smart TVs offer users a wide range of media capabilities, and one of the most popular features is smartphone image duplication, which allows you to display photos, videos, presentations or even mobile games on the big screen at high resolution. Built-in support for Miracast technology and Google Cast protocol makes the customization process as simple as possible, but beginners often have questions about finding the right menus.

In this article, we will discuss how to activate Screen Mirroring on Mi TVs of various series, learn about the nuances of connecting Android and iOS devices, and get answers to frequent problems with the visibility of devices on the network.

Before you start setting up, make sure your TV is connected to the Internet and your smartphone is on the same Wi-Fi network. This is a basic requirement for most wireless broadcast protocols to work. If you just bought the appliance, you may need to set up the network initially via the remote.

Preparation of equipment and network

The foundation of successful broadcasting is the right organization of the local network: both devices — and Xiaomi TV and your mobile gadget — must be connected to the same router. Often users face the problem when the phone is running on a mobile 4G and TV via cable, or they are connected to different frequencies of the router (2.4 GHz and 5 GHz), which can cause difficulty in detection.

It is recommended to use a 5GHz network if your router and TV support this standard, which will provide higher channel bandwidth, which is critical for image transmission in Full HD or 4K resolution. In noisy airspace in apartment buildings, this will also give a more stable signal.

Check if your Mi TV software is updated to the latest version.Manufacturers regularly release patches that improve compatibility with newer versions of Android and iOS. Old firmware may not work properly with new security protocols or codecs.

It is important to note that some corporate or public Wi-Fi networks may block direct connection between devices (Client Isolation function), in which case the wireless broadcast will not work, and you will need to use a personal router or create an access point.

💡

If you have a dual-band router, try connecting both devices to a 5GHz network for better speed, but remember that it has a range less than that of 2.4GHz.

Activation of the feature on the Xiaomi TV

On Xiaomi TVs running Android TV or PatchWall, the streaming feature is usually built-in and does not require additional apps to be installed, but in some regions or older models it needs to be manually activated via the settings menu.

To enable, go to the main menu and find Settings. Next, select Network and Internet or Connections, where the Translation or Miracast option may be located. On newer models, this feature is often available directly from the top drop-down menu if you click the settings button on the remote.

If you are using a version of the system that supports Google Chromecast built-in, you may not need to turn on a separate TV – the TV simply becomes visible to other devices on the network, in which case a screensaver with the name of the model waiting to be connected can appear on the screen.

Note that different versions of MIUI for TV firmware may have different locations. Look for sections associated with the screen, display or network projections. If you can't find them, use the built-in search settings to search for "broadcast."

Broadcast from Android-smartphone

Android smartphone owners have several ways to connect, the most versatile is using the built-in Translation or Smart View (on Samsung), Projection (on Xiaomi/Redmi). First, open the notification curtain and find the appropriate icon.

Once you activate the search, the phone will start scanning the available devices. When your Mi TV name appears on the list, click on it. A request for permission to connect may appear on the TV screen, which must be confirmed by the remote, this is a security measure to prevent outsiders from broadcasting content to your screen.

For more advanced work, such as displaying images only from a particular app (YouTube, Netflix), use the Cast button inside the app itself, which allows you to use the phone as a remote control without using the battery to continuously stream video, since the content is downloaded directly from the TV.

⚠️ Note: When using full screen mirroring (Miracast), the image on the TV may have black stripes at the edges if the proportions of the smartphone screen (e.g., 20:9) differ from those of the TV (16:9.

If standard means to connect fail, you can use the application Google Home. It allows you to control devices with support for Chromecast and start broadcasting the entire screen of the smartphone with a single button "Translate screen".

Connecting Apple devices (iOS/macOS)

Users of the Apple ecosystem can also easily display an image on a Xiaomi TV, as most modern models support the AirPlay 2 protocol. Make sure that AirPlay support is enabled on the TV in the settings (usually located in the "Apple AirPlay and HomeKit" section).

To start the screen replay, open the Control Point on your iPhone or iPad (swipe down from the top right corner or bottom up on older models). Click the Screen Replay icon (two rectangles) and select your Mi TV from the list.

When you first connect to your TV, you may have a four-digit code that you need to type into your iPhone, which ensures that you connect to your device, and after a successful pair of devices, you won't be asked for the code in the future.

💡

It's critical to keep AirPlay running smoothly, so if you have guest Wi-Fi on your phones, the streaming won't work.

Also, many popular apps like YouTube or Vimeo have a built-in broadcast button that works on iOS independently of AirPlay.Just click on the rectangle icon with the waves in the video corner and select the TV.

Use of third-party applications

In some cases, the built-in tools may not work stable or support certain video formats, then third-party applications come to the rescue, which can be installed on both a TV (via the Google Play store or GetApps) and a smartphone.

A popular solution is Xiaomi’s TV Assistant, which is often pre-installed or downloadable, which allows you to not only stream the screen, but also manage files, transfer photos and videos from the gallery, and widely used applications like Web Video Caster for streaming videos from the browser.

For users who want to stream DRM-protected content (such as paid subscriptions), it is important to know that some intermediary apps may not pass protection and the screen will be black.

⚠️ Note: When installing unknown applications from APK-Files (not from the official store) on Android TV Be careful, they may contain ads or malicious code that will slow down the system.

If you use a Windows 10/11 laptop, you can also use the Connection feature on a system that runs on Miracast protocol, similar to Android smartphones.

Troubleshooting and troubleshooting

Despite the simplicity of the technology, users can run into problems, the most common being "Device not found." 90% of the time, it's done by checking that both devices are connected to the same network, and rebooting the router helps, because it could fog up and stop routing broadcast packets correctly.

Another problem is de-synchronizing sound and image or delay (lags). This often happens when the Wi-Fi channel is congested. Try turning off other devices consuming traffic or switching the router to a less busy frequency. Also make sure that the TV does not start heavy background processes.

If the image is interrupted or of poor quality, check the Wi-Fi signal. For TVs located far from the router, it is recommended to use a Wi-Fi adapter with an external antenna or connect the TV with a LAN cable, and leave the smartphone over Wi-Fi (although for Miracast this is not always ideal, since direct data exchange goes through the router).

If the feature is completely disabled, you may need to reset your network settings on your TV. Go to Settings → Network → Reset network settings. This will delete stored Wi-Fi passwords, but can correct stack software errors.
