Modern Xiaomi smartphones have powerful displays, but to watch movies in high resolution or present slides, it is better to use a large TV screen. Fortunately, the Mi Home ecosystem and the Android operating system provide many built-in tools for wireless media transmission. You do not need complex cables or adapters, as long as both devices support standard communication protocols.
In this article, we will take a look at how to stream content from phone to TV using only home WiFi. We will look at both native MIUI and HyperOS features, and third-party solutions for TVs that do not support direct connection. Understanding the principles of Miracast protocol will help you avoid delays and desynchronization of sound.
Before you start setting up, make sure your smartphone and TV are connected to the same access point, a critical condition for most broadcast methods to work smoothly. If you use a dual-band router, it’s best to use a 5GHz network to transmit high-quality video without buffering.
Equipment preparation and network setup
The first step to successful synchronization is to organize your local network correctly. Make sure that the router does not include Client Isolation, which prevents devices within the network from communicating with each other. In most home routers, this feature is disabled by default, but in corporate networks or hotel WiFi, it can block the detection of the TV.
Check if your TV supports Smart TV technology. Most of today's models from Samsung, LG, Sony and Philips have built-in WiFi Direct or Miracast modules. If you have a regular TV, you'll need an external console, such as an Android TV Box or Chromecast. Without a signal receiver on the TV side, you can't transmit images.
On a Xiaomi smartphone, go to Settings → About phone and check for system updates. On a TV, similar actions are performed in the Settings → Support → Software Update section (the path may vary depending on the brand). Older versions of firmware often contain bugs in wireless communication modules.
Android tools can be used to diagnose connection quality. The Developer Menu (if enabled) includes WiFi status and link speed, and the stability of the link directly affects the smoothness of 4K video playback.
Broadcasting through the built-in Translation function (Miracast)
The easiest and most common way to bring Xiaomi’s screen to your TV is by using Miracast technology. In MIUI and HyperOS shells, this feature is called Translation or Wireless display. It allows you to duplicate images from your smartphone in real time, which is ideal for showing photos, videos from a gallery or even games.
To start the process, lower the notification curtain and find the Translation icon. If it is not on the main panel, click on the edit button (usually three dots or a pencil) and drag the icon to the active area. Once turned on, the phone will start searching for available devices on the WiFi network.
You have to run an app on your TV. It's called Smart View on Samsung, Screen Share on LG, Mirror Share on Sony. Once the TV is listed on your smartphone, click on it to pair it. You can have a confirmation request on your TV screen that you need to accept by remote control.
☑️ Pre-broadcast checks
It's important to consider that when you use Miracast, the image is transmitted in real time, which puts a strain on the processor and battery of the smartphone. The phone screen will burn all the time, and the energy consumption will increase. For long views, it is better to connect the phone to the charger.
💡
If the broadcast is interrupted, try to turn off Bluetooth on your phone, as it can cause interference in the 2.4 GHz band.
Using the Google Home app for Chromecast
If your TV is equipped with an Android TV or Google Cast system, or a Chromecast is connected to it, the best solution is to use the official Google Home application, which provides a more stable transfer of content from streaming applications (YouTube, Netflix, Spotify) compared to simple screen duplication.
Install the Google Home app from the Google Play store and log in to your account. The app will automatically find Chromecast devices on your network. Select your TV from the list of devices. In the control menu that opens, click the "Cast screen" button.
The main advantage of this method is that the video is streamed directly from the server to the TV, and the phone acts only as a remote control, which means that you can fold the application, answer the phone or use other functions of the phone without interrupting the playback of the movie on the big screen.
The picture quality is often higher when using Chromecast, as the TV itself decodes the video stream using its hardware resources, supports resolution up to 4K and Dolby Atmos sound, if the hardware allows it.
What if Google Home doesn’t see TV?
Video and photo streaming via DLNA and Mi Remote
To view the media library stored in the memory of a smartphone, you do not need to duplicate the entire screen. The DLNA protocol allows you to transfer only content (video files, photos, music) to the TV, which acts as a renderer, which saves battery power and reduces the load on the WiFi channel.
In smartphones Xiaomi is often preinstalled application Mi Remote (Mi remote), which can work with the DLNA-Open the app, select your TV (if added as an IR remote or network device) and find the media broadcast function. You can also use a standard video player or gallery: open the file, click Translate (the wave rectangle icon) and select TV.
Popular video players like VLC for Android or MX Player have built-in DLNA/Chromecast support. VLC requires you to open menus, select Output, and specify your target device, which is ideal for watching movies downloaded in high bitrate, as buffering is more efficient.
| Method | Delay. | Quality. | Battery consumption |
|---|---|---|---|
| Miracast | Low (for games) | Depends on the signal. | High-pitched |
| Google Cast | Minimum | Maximum (4K) | Medium. |
| DLNA | No (file) | Original | Low. |
When using DLNA, it is important that the video file format is supported by the TV. If the TV cannot decode the audio codec (for example, DTS or AC3), the sound may be absent even if the picture is coming. In such cases, it is better to use the screen broadcast (Miracast), where the phone takes over the decoding.
Third-party applications for complex cases
Sometimes the built-in tools don't work, especially if the TV is old or a rare brand, and in these cases, the universal apps from Google Play come to the rescue, one of the leaders being the TV Cast app or Web Video Caster.
These apps are browser-based, and you open a video on a site inside an app, and it sends a stream link directly to the TV, and it allows you to stream content from websites that don't have official Smart TV apps.
⚠️ Note: Some free versions of apps may include ad inserts or have session time limits. For ongoing use, it is better to consider buying a Pro version.
Another powerful tool is the AirScreen app (installed on a TV if it’s an Android TV), which emulates AirPlay and Miracast reception, making it compatible with almost 100% of devices. If your Xiaomi is not “friendly” with a Samsung TV, installing such an intermediary on TV solves 90% of the problems.
When choosing third-party software, pay attention to permissions. The application needs access to the local network and microphone (to transmit sound), without these rights, the broadcast will not work.
💡
Universal browser applications often cope with the translation of “heavy” content from sites better than the built-in system.
Solving Connection and Delay Problems
Even with the right setup, there can be technical problems, the most common of which is the desynchronization of sound and image, and if the actors' lips don't get into words, try looking for the Audio Delay setting in your TV settings and adjusting it manually.
If the broadcast is constantly interrupted or the image is “dropped” on squares, the problem lies in a weak WiFi signal. Try to get closer to the router or, more effectively, switch to the 5 GHz band. The 2.4 GHz range is often clogged with signals from neighbors and Bluetooth devices, which creates interference.
In some cases, resetting network settings on your phone helps. Go to Settings → Connection and Sharing → Reset WiFi, mobile networks and Bluetooth. This won’t delete your passwords, but will update network configurations.
It’s also worth checking if the router is running Guest Network mode, and devices on the guest network are often isolated from the main network, so the phone and TV may not see each other even in the same apartment.
