Modern Smart TV Xiaomi smartphones are powerful multimedia devices capable of playing high-definition content, but smartphone size still remains a limiting factor when watching movies. Users regularly want to transfer images from a small screen to a larger one, especially when sharing photos with family or watching a movie online. Fortunately, the ecosystem Android TVThe platform that powers Xiaomi TVs offers a variety of built-in wireless data transfer tools that eliminate the need for additional cables or adapters.
The main advantage of using WiFi connections The advantage of this method is the absence of physical distance restrictions and the ability to control playback directly from your smartphone, while the TV functions as a monitor. There are several video streaming protocols, such as Miracast, DLNA, and Google Cast, each with its own operating features and compatibility with various apps. In this article, we'll cover all available methods in detail, help you set up your equipment, and troubleshoot common errors that occur during device synchronization.
Before you begin setting up, you need to make sure that both devices—the mobile gadget and the TV set-top box or panel—are connected to the same wireless network. fundamental condition, which, if ignored, in 90% of cases results in the inability of devices to discover each other. If your router broadcasts the network on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), make sure both devices "see" the same network segment, as some older search algorithms may not work across different subnets.
Preparing equipment and network for broadcasting
The first step in setting up a wireless connection is to properly configure your router, as it acts as the intermediary for transmitting the video stream. For stable operation streaming High-definition video (Full HD or 4K) requires sufficient bandwidth. We recommend using WiFi 5 (802.11ac) or later, which provides the necessary data transfer speeds without lag or image artifacts.
It's also important to consider the location of the devices relative to the access point. If the router is in another room behind thick concrete walls, the signal may weaken, leading to audio and video desynchronization or intermittent buffering. The ideal scenario is for all participants to be within a strong signal range, where the battery level indicator on the smartphone shows full or almost full.
Don't forget about software updates. TV firmware Xiaomi Mi TV Smartphone operating systems regularly receive security patches and functionality improvements. Often, the issue of a missing feature can be resolved by simply updating the software to the latest available version via the settings menu.
⚠️ Important: If you're using a guest WiFi network or a network with AP Isolation, devices won't be able to see each other. Make sure wireless client isolation is disabled for the main network in your router settings.
Using Chromecast Built-in
The most universal and frequently used method is technology Google Cast, built directly into the operating system of Xiaomi TVs. This feature allows you to stream content from supported apps (YouTube, Netflix, Vimeo, and online cinemas) with the touch of a button. Unlike full screen cloning, the phone acts only as a remote control, and the TV downloads the video stream directly from the internet, saving battery life.
To get started, open the video app on your mobile device. At the top or bottom of the player, look for the distinctive rectangle icon with waves in the corner—this is the broadcast button. After clicking it, the system will offer a list of available devices on the network. Select yours. Xiaomi TV from the list, and after a few seconds the image will appear on the big screen.
If the cast icon doesn't appear, check that you're logged into the same Google account on both devices. While this isn't always necessary for basic functionality, having a single account significantly simplifies search and improves connection stability. Also, make sure the app you want to cast from supports the Cast protocol.
Screencasting via Miracast (Wireless Display)
When you need to display exactly what's on your phone's display—a menu, a game, a browser, or an app that doesn't support Cast—technology comes to the rescue. MiracastIn Xiaomi TVs, this feature is often called "Wireless Monitor" or "Wireless Display." It creates a direct connection between devices, mirroring the video signal in real time.
Activation of the function on the TV side usually occurs automatically when searching for devices, but in some firmware versions MIUI for TV You may need to manually launch the Miracast or Wireless Casting app from the Input list. Once launched, a connection screen will appear.
On an Android smartphone, the process has different names depending on the operating system: "Cast," "Smart View," "Projection," or "Connect to a wireless display." Find this option in the notification shade or in the display settings. After scanning, select your TV. The image from your phone will appear on the TV, and the smartphone may switch to landscape mode.
Settings → Connected devices → Connect to a wireless displayIt's worth noting that when using Miracast, the phone continues to consume power for encoding and transmitting video, so the battery will drain faster. Furthermore, a slight input lag is possible, making this method less suitable for fast-paced shooters, but perfectly acceptable for turn-based strategy games or presentations.
☑️ Pre-launch check for Miracast
Specifics of working with Apple devices (AirPlay)
iPhone and iPad owners may face compatibility issues as the Apple ecosystem uses its own proprietary protocol. AirPlayHowever, modern Xiaomi TVs often have built-in AirPlay 2 support, allowing you to stream content without installing additional software. If your TV model supports this standard, simply open Control Center on your iPhone and select "Screen Mirroring."
If your TV doesn't have native AirPlay support, installing a dedicated app on the TV itself via the Google Play Store can help. Popular solutions include apps like "AirScreen" or "AirPin," which emulate an AirPlay receiver, making the TV visible to Apple devices.
After installing such an emulator on Xiaomi TV, launch it, and follow the on-screen instructions. You'll usually need to allow access to your local network. Then, a new device will appear in the casting menu on your iPhone. Casting quality may vary when using third-party emulators, but for viewing photos and videos from your gallery, this is usually more than sufficient.
⚠️ Note: When using AirPlay emulators on Android TV, audio may become desynchronized when playing high-bitrate videos. Try changing the audio codec or buffering settings in the emulator app's settings.
Using DLNA to Play Media Files
If your goal is to play a video file stored in your phone's memory or run a movie from local storage, the most efficient protocol will be DLNAIt doesn't broadcast the screen, but rather transmits the media file itself to the TV's decoder, which then plays it. This frees up the phone's resources and ensures maximum picture quality.
To implement this method, you need to install a media server or player app on your smartphone that supports DLNA/UPnP. Excellent examples include VLC for Android, BubbleUPnP or built-in galleries from some manufacturers. After opening a video file in such an app, select the "Stream" option or the device icon, and choose your TV.
Xiaomi TVs usually automatically detect DLNA servers on the network. You can also launch the Media Player app on the TV itself, go to the Sources or Network section, and find the folder containing your smartphone's files. This allows you to use your phone as a network-attached storage (NAS) device to view content on the big screen.
| Protocol | Main purpose | Latency | Phone addiction |
|---|---|---|---|
| Chromecast | Streaming from online services | Low | Low (remote control) |
| Miracast | Full screen cloning | Medium/High | High (phone encodes) |
| DLNA | Local files (video/photo) | Low | Average (start only) |
| AirPlay | Broadcasting from Apple devices | Low | Depends on implementation |
Why does the video jerk when broadcasting?
If you experience choppy video transmission, your WiFi channel is likely low on bandwidth. Try switching your router to the 5 GHz channel if it supports dual-band operation, or move your devices closer to the router.
Solving typical problems and diagnostics
Despite the simplicity of the technology, users may encounter a number of difficulties. The most common is that the TV doesn't detect the phone. In 99% of cases, this can be resolved by checking whether the device is on the same network. Sometimes routers have a "client isolation" feature that prevents devices within the network from communicating with each other. This feature must be disabled in the router settings.
Another common issue is poor image quality or constant buffering. This indicates a weak WiFi signal or channel congestion from neighboring networks. In such cases, rebooting the router can help, forcing it to select a less congested frequency channel. It's also a good idea to close background apps on your smartphone that may be consuming data.
If there's sound but no image (black screen), the app you're streaming may be copyright-protected (DRM). Some services, such as Netflix or online movie theaters, block Miracast, requiring the use of the TV's built-in app or the Chromecast protocol.

In rare cases, resetting the network settings on your phone or deleting the WiFi network profile and reconnecting with the password can help. This clears the network connection cache and eliminates possible IP address conflicts.
Why can't my Xiaomi TV find my phone?
Make sure location services (GPS) are enabled on your phone. In modern Android versions, scanning for WiFi devices for the broadcast function requires GPS to be enabled. Also, check that your router doesn't block communication between clients.
Is it possible to display the screen via USB cable?
Xiaomi TVs typically don't support direct USB video connection (like HDMI). The USB port is used for playing files from flash drives. For screen sharing, use only wireless methods or dedicated USB-to-HDMI adapters if your phone supports them.
How to improve picture quality during broadcasting?
Close all unnecessary apps on your smartphone, move closer to the router, and make sure nothing is shielding the antennas. If possible, configure the router to operate in 5 GHz-only mode (802.11ac/ax) for maximum speed.
Does the broadcast work without the Internet?
Yes, Miracast and DLNA don't require internet access; a local WiFi network is sufficient. However, Chromecast and online services require internet access.
