Xiaomi’s modern ecosystem offers users many ways to interact between devices, and the smartphone-TV bundle is one of the most sought-after features. When it comes to bringing a presentation, family video or game to the big screen, owners often wonder how to connect the Mi TV to a Xiaomi phone as quickly as possible and without the use of unnecessary wires. The setup process can vary depending on the TV model, the version of the MIUI or HyperOS operating system, and the type of content used.
In this article, we will take a look at all the synchronization methods available, from built-in wireless image transfer functions to the use of specialized control applications. You will learn how to configure Miracast to duplicate the screen, how to stream video over the DLNA protocol, and how to turn a smartphone into a universal remote control. Understanding these nuances will allow you to unlock the full potential of your smart technology.
In addition, we will discuss the issues of connection stability and consider the typical problems that users face when trying to connect devices into a single network. The correct setting of the router and choosing the right frequency range can dramatically affect the quality of the transmitted signal.
Equipment preparation and network environment
Before starting the synchronization process, you need to make sure that both devices are in the right network environment. A fundamental requirement for most wireless methods is to connect your smartphone and TV to the same Wi-Fi network. If your router supports dual-band operation, it is recommended to use a 5 GHz network, as it provides higher bandwidth, which is critical for high-resolution video streaming without delays.
Check that the Mi TV or Mi Box has a wireless display feature on it. Depending on the year of the model and the version of the Android TV operating system, this option can be called differently. It is usually in the network settings section or in the signal source menu. Some models require you to manually run the Wireless Display application to make the device visible for search.
⚠️ Warning: Make sure the router does not activate the “Customer Isolation” function» (AP Isolation, which prevents devices within the LAN from communicating with each other, if enabled, the phone simply won't "see" the TV even when on the same network.
It’s also worth updating the software on both devices to the latest available version. Manufacturers regularly release patches that improve data protocol compatibility. Go to Settings → About TV → System Update on TV and a similar section in smartphone settings to eliminate errors associated with outdated software.
Broadcasting the screen through the built-in function “Wireless screen”
The most common way to completely duplicate a smartphone image to a TV is by using Miracast technology. In the MIUI shell, this feature is often called Wireless Screen or Translation, which allows you to broadcast everything that happens on the phone's display, including menus, games and application desktops, in real time.
To activate the function, open the notification curtain on your smartphone and look for the Translation or Wireless screen icon. If the icon is not in quick access, go to Settings → Connection and Sharing → Broadcast. Turn on the switch and the phone will start searching for available devices on your Wi-Fi network. When your Mi TV name appears on the screen, click on it to start pairing.
- 📺 A request for confirmation of connection may appear on the TV – use the remote to agree.
- 📱 On a smartphone, the screen can go out or change orientation, which is normal behavior when starting mirroring mode.
- 📶 Using this method, the smartphone and TV create a direct Wi-Fi Direct connection, which can temporarily reduce the speed of the Internet on the phone.
Importantly, this method puts a high strain on the smartphone battery, since the processor and Wi-Fi module are working in a strengthened mode. For long sessions, it is recommended to keep the phone connected to the charger. In addition, the horizontal orientation of the image on the TV will depend on the position of the smartphone, if the broadcast settings do not block autorotation.
💡
To reduce the delay (input lag) during games through a wireless screen, on some models of Xiaomi TVs in the image settings, you should switch the mode to “Game” or “PC”.
Using the Mi Remote application for management
If your goal is not to duplicate the screen, but to control the TV comfortably, the perfect solution is the official Mi Remote app, which is pre-installed on most Xiaomi and Redmi smartphones, and which allows you to use the smartphone as a full-fledged remote, which is especially convenient when the physical remote is lost or its batteries are exhausted.
There are two main ways to connect via Mi Remote: One is through an infrared port (IR Blaster), if you have one on your smartphone. In this case, you don't need a network connection, the phone just mimics the signals of a conventional remote; the second, more modern way is through Wi-Fi, which allows you to control even the functions of the TV that are not available through an infrared port, such as typing from a phone keyboard or using voice search.
To set up your Wi-Fi remote, open the app, click on the + sign and select the TV category. From the list of brands, find Mi or Xiaomi. The app will offer several code options or automatically find the TV on the network. Once successfully paired, you will be able to control volume, signal sources and navigation through the menu.

Broadcasting multimedia via DLNA and Chromecast
To view photos, videos or listen to music stored in the phone’s memory, you don’t need to duplicate the entire screen. DLNA and Google Cast (Chromecast built-in) protocols allow you to stream a particular media file directly from the Internet or local storage to the TV, freeing the smartphone for other tasks.
Most video-watching apps, like YouTube, Netflix, or VK Video, have a live stream button built in. It looks like a rectangle with waves in the corner. When you click on it, you'll see a list of available devices. When you select your Mi TV, you'll play directly on your TV, and the picture quality is often higher than when you mirror the screen, because the TV itself decodes the stream.
If you want to stream personal photos or videos from the gallery, you can use the built-in system or third-party media applications that support Cast. In the standard Xiaomi gallery, when you open a photo or video, you can also see a broadcast icon, which is a convenient way to show vacation pictures to guests on the big screen without having to transfer files over cable.

Wired connection via USB-C to HDMI
In situations where the wireless network is unstable or requires the transmission of images in maximum quality without compression, it is advisable to use a wired connection. To do this, your smartphone must support video output technology via a USB Type-C port (DisplayPort Alt Mode). Not all Xiaomi models support the output of images via cable, usually the flagship series Mi and Xiaomi (for example, the series 11, 12, 13, 14 and some Pro models).
To connect, you will need a USB-C to HDMI adapter. One end of the adapter is inserted into the smartphone charging connector, and the second connects a standard HDMI cable that goes to the TV. After connecting, you need to switch the signal source on the TV (Source or Input) to the appropriate HDMI port.
The advantage of this method is that it has no delays and depends on the quality of the Wi-Fi signal, and the image is transmitted in native resolution, and the sound is output through the acoustic system of the TV, which is ideal for watching movies in 4K or presenting heavy graphics files.
⚠️ Note: When using cheap adapters without additional power, the smartphone may not “pull” the output of the video signal, and the image will not appear.
What if there is a picture but no sound?
Solving problems and adjusting productivity
Even with the right setup, users may experience audio and video desynchronization, intermittent connection breaks, or poor picture quality. Often the cause is overloaded Wi-Fi channels by neighbouring routers, in which case manual channel selection in router settings or switching to a 5 GHz band that is less crowded helps.
If the broadcast is slowing down, try lowering the resolution of the output image. The Wireless screen menu on a smartphone often has quality settings. It is also worth closing the background apps on the phone that can consume traffic or CPU resources. For games with high dynamics, a wireless connection can give a noticeable delay, so for competitive shooters it is better to use a wired method or play directly on the phone screen.
In some cases, resetting network settings on the TV helps. Go to Settings → Network and Internet, and select "Forget Network," and then reconnect by entering your password. IP-address and resets possible addressing conflicts in the local network.
💡
The stability of the connection depends on the power of the router signal and the absence of physical obstacles between devices.
