How to bring a movie from phone to TV Xiaomi: the complete guide

Modern smartphones have powerful screens, but to watch high-quality movies you still want to use a large display Xiaomi TV or Redmi TV. Fortunately, the ecosystem of the Chinese manufacturer allows you to quickly and conveniently broadcast content from a mobile device to a TV without unnecessary wires, this opens access to the phone’s media library, streaming services and personal video archives on a screen with a diagonal of 43 inches or more.

There are several proven ways to connect, each with its own characteristics: some require stable Wi-Fi, others work through a direct connection or even cable, and the best choice depends on your TV model, the version of the Android operating system or PatchWall, and the format of the video file you plan to play.

In this guide, we will take a look at all the current broadcasting methods, from built-in features to third-party applications, learn how to fix common errors when the TV can’t see the phone, and learn how to ensure maximum picture quality without delay, which will turn an ordinary evening into a real movie theater in your home.

Preparation of equipment and network for broadcasting

Before setting up, make sure that both devices are in the same network conditions. The fundamental requirement for wireless protocols is to connect your smartphone and Xiaomi TV to the same Wi-Fi network. If your router is sending out a signal at 2.4 GHz and 5 GHz with different network names (SSIDs), make sure that both gadgets are connected to one of them, preferably 5 GHz for high data rates.

Check the software's relevance on both devices. On a TV, you can do this by going to Settings → About TV → System Update. On a smartphone, updates usually come automatically, but you can check them manually in the Google Play settings or system menu. Outdated Wi-Fi module drivers often cause connection breaks when you try to start a heavy video stream.

⚠️ Note: Using the "Guest Network" mode on the router may block interaction between devices within the LAN. Make sure that client isolation is not possible (AP Isolation) disabled in router settings.

Also worth paying attention to battery charge: the wireless broadcast process, especially in high resolution 4K HDR, consumes a significant amount of power, it is recommended to keep the phone connected to the charger or make sure that the battery is charged at least 40-50% so that the device does not go into power saving mode at the most inopportune time.

Use of the built-in Mi Cast and Miracast function

The fastest way to display an image is to use native Mi Cast technology, which is built into the MIUI TV and PatchWall shell, which allows you to duplicate the screen of a smartphone completely or broadcast only video from a gallery. The technology is based on the Miracast standard, which provides a video signal with minimal latency directly from the video output of the phone's GPU.

To activate the feature on your Xiaomi TV, find the Mi Cast app in the main menu or in the "My apps" section. After you start, you will have a wait for connection on the screen. On a smartphone with a MIUI shell, you need to open the notification curtain, find the "Translation" icon (or "Cast") and select your TV from the list of available devices. On a pure Android, the path may be different: Settings → Connected devices → Broadcast.

• 📱 Open the notification curtain on your phone and press Translation".
• 📺 Launch the Mi Cast app on Xiaomi TV.
• 🔗 Select the name of your TV in the list on your smartphone.
• ▶️ Wait for the image to appear and start the video.

If standard search doesn’t work, try using the Google Home app. It automatically detects Chromecast built-in devices found in many Xiaomi TV models. Click on the Translate screen icon in the app and the phone will start mirroring everything that happens on its display, including notifications and system sounds.

Broadcasting via DLNA protocol and built-in player

Unlike Miracast, the DLNA protocol does not duplicate the screen, but instead transfers the media file itself to the TV for decoding, meaning that the phone acts as a remote control, and the entire load of video processing is taken over by a Smart TV, which allows you to watch video in the background, answer calls or use other applications on your smartphone without interrupting playback on the large screen.

To implement this method, you will need a file manager on a DLNA-enabled phone or a dedicated video player, such as VLC for Android or Xiaomi Video. Open a video file on your phone, find the Translation icon (a rectangle with waves) and select your TV. The system will automatically send a data stream to the TV, and playback will begin through the built-in TV player.

The advantage of DLNA is that it supports a wider range of codecs by the TV itself, as Xiaomi TV has a more powerful decoding processor than the average smartphone. In addition, the picture quality is often more stable, as it transmits the finished video stream, rather than a compressed desktop image.

Apps for streaming: YouTube, Netflix and others

Popular streaming services use their own transmission protocol, often referred to as Google Cast. This is the most optimized way to view online content. When you click a stream icon on a YouTube or Netflix app on your phone, you don't upload the channel to your smartphone, you just send the TV a command to "please play this video on this link."

The TV downloads video streams from YouTube or Netflix servers, which guarantees maximum picture quality (up to 4K and HDR) and no load on the phone’s battery. The main condition is that the TV must be installed with the appropriate application or it must be built into the PatchWall system.

It is important to note that some content-protected movies (DRM-protection) may not be broadcast through a simple screen mirror due to copyright restrictions, in such cases using the Cast button inside the application itself is the only legal and working solution for displaying an image on an external display.

Wired connection via USB-C to HDMI

If the wireless connection is unstable or requires transmission without compression, you can use a cable connection. This requires a USB-C to HDMI adapter. However, not all Xiaomi smartphones support video output via the charging port. This feature (displayPort Alt Mode) is usually only available in the flagship models of the Mi series, Xiaomi Number series and some Black Shark models.

Connect the adapter to the smartphone, and HDMI-Connect the adapter and free port HDMI switch the signal source to the TV to the appropriate input (e.g, HDMI The image should appear automatically. If the phone supports desktop mode, the interface can adapt to a horizontal orientation, resembling a computer environment.

The use of cable also solves the problem of interference from neighboring Wi-Fi networks, which is especially important in apartment buildings, where the air is heavily clogged with signals from neighbors' routers.

Translation management via Mi Remote

Once a movie is launched, the phone can become a universal remote. The Mi Remote app (or MIUI's built-in Remote feature) lets you control your TV even without an infrared port using a Wi-Fi connection, which is especially useful if the physical remote is lost or its batteries are out of order.

To pair, open the app on your phone, click Add Device, and select the Xiaomi brand. The program will prompt you to press a few buttons on your smartphone screen to confirm (pair). Once you have successfully set up, you can adjust volume, switch sources, and even use voice input to search for movies directly from your phone.

The control feature also allows you to close unnecessary apps on the TV if the system starts to slow down, or quickly return to the main menu without getting out of the couch, which turns the smartphone into a powerful multimedia control center.

Solution: TV can't see phone

One of the most common problems is when devices are on the same network but do not see each other. Often the reason lies in the settings of the router firewall or antivirus on the smartphone, which block local device detection (UPnP). Try temporarily turning off mobile Internet on the phone, leaving only Wi-Fi to force the system to search for devices on the local network.

Another common reason is different regions in account settings: If your phone is registered in China and your TV has global firmware (or vice versa), some Xiaomi services may not work correctly.

⚠️ Note: If you use a guest Wi-Fi network, the devices will be isolated from each other by default.

If you have persistent buffering problems when viewing heavy files, try lowering the bitrate of the video or using a wired connection, and rebooting a router that might have been clogged with a DNS cache helps.

💡

For stable 4K video broadcast, make sure the router supports either Wi-Fi 5 (AC) or Wi-Fi 6 (AX) standard. Older routers may not pull the stream.
