Xiaomi’s modern Smart TV offers access to a huge amount of entertainment content, but it’s sometimes more convenient to run the video on a smartphone and stream it to the big screen.This can be a movie saved in the device’s memory, or an online broadcast that the TV’s built-in app doesn’t support. Xiaomi TV and Redmi or Poco smartphones often work in the same ecosystem, making it much easier to synchronize devices.
In this article, we'll look at all the current techniques for displaying a smartphone image onto a TV screen. We'll look at wireless technologies like Miracast and DLNA, and wired solutions for those who prefer a stable connection without delay. You'll learn how to configure the broadcast in a few minutes and eliminate the need to watch content on a small display.
Choosing the right method depends on your goals: whether you want to simply duplicate a screen or stream a specific file from a gallery. For streaming videos from YouTube or Netflix, built-in broadcast protocols are better suited, whereas for games or presentations, you will need full screen mirroring. Understanding the differences between these technologies will help you avoid delays and desynchronization of sound.
Before you start setting up, make sure both devices are connected to the same Wi-Fi network. This is a fundamental condition for most wireless data protocols to work. If a router distributes networks at different frequencies (2.4 GHz and 5 GHz), try to connect your phone and TV to one of them, although modern routers often combine them into a single network.
Use of the built-in Mi Drop function and screen broadcast
The fastest way to display an image is to use the standard Android feature, which is often called Translation, Smart View, or Wireless Monitor. In the MIUI or HyperOS shell, this tool is integrated into the control panel. You do not need to install third-party apps if both devices are on the same LAN.
On a Xiaomi TV, you need to activate the signal reception mode. To do this, go to the app menu and find the Wireless Monitor or Mi Screen Cast program. After you start, the device name and the connection wait will appear on the screen. Now take the smartphone and lower the notification curtain down.
- 📱 Find the Translation or Projection icon in the phone’s Quick Settings Panel.
- 📺 Choose from the list of your Xiaomi Mi TV TV.
- 🔗 Confirm the connection on the TV screen if an access request appears.
- 🎬 Open a gallery or video player and spread the video to the full screen.
⚠️ Note: When using Mirracast, the smartphone can heat up more, and the battery will be consumed faster, since the video encoder works in a strengthened mode.
If the standard icon is not found, search the phone settings by typing in the “Translation” request. In some firmware versions, this feature is hidden in the Settings menu → Connection and Sharing → Broadcast. Once activated, the phone will start searching for available devices within Wi-Fi range.
Chromecast Technology and Google Home App
Many Xiaomi TVs run on Android TV or have built-in support for Google Cast technology.This allows you to stream content from apps directly without loading the phone's processor with full screen mirroring. Google Home is ideal for managing this process.
Download and install the Google Home app from the Play Market Store. Once installed, the program will automatically detect all devices on your network, including TVs, speakers and smart lamps. Find your TV on the list and click on it to control it.
☑️ Pre-broadcast checks
In the app interface, select the Cast my screen button, and the system will warn you that you will see all notifications and actions from your smartphone on a large screen, which is a great way to show photos to friends or run videos from a browser that does not have a Translate button.
- 🌐 Open the Google Home app on your smartphone.
- 📺 Select your Xiaomi TV from the list of devices.
- ▶️ Click the “Translate Screen” button in the bottom corner.
- 🎬 Run the video in any player or browser on your phone.
The advantage of the Chromecast method is that the TV itself decodes the video stream if the app supports this feature. For example, when watching YouTube, you can turn the app on your phone or even turn off the screen, and the video will continue to go on the TV. This saves battery power and frees up the smartphone for other tasks.
Broadcasting via DLNA and VLC Player
If you want to play a video file that's already downloaded to your phone's memory, DLNA is the best solution, which allows you to transfer media over a local network without compressing quality, and you need to install a third-party player on your smartphone, like VLC for Android, which is one of the most popular and functional.
Run the VLC app on your phone and go to the Network or Review tab. The player will automatically scan the network and find your Xiaomi TV. If the TV is not visible, make sure it has DLNA enabled (sometimes called Media Player or Renderer).
| Parameter | Wireless monitor (Miracast) | DLNA (VLC Player) | Chromecast |
|---|---|---|---|
| Type of transmission | Screen mirroring | File streaming | Streaming transmission/Mirroring |
| Impact on the phone | High (screen on fire) | Low (can be blocked) | Low (depending on the regime) |
| Quality. | Depends on the Wi-Fi signal. | Original (no loss) | Adaptive. |
Unlike Miracast, when using DLNA, you can control playback (pause, rewind) directly from your phone, but the phone itself doesn't have to keep the screen on.This is especially handy when watching long movies late at night when the bright screen of the smartphone can get in the way.
⚠️ Note: Video file formats must be supported by the TV. TV Does not play a sound or picture, try changing the codec in the player settings or broadcast the entire screen through Miracast.
Why does video slow down when broadcasting?
Wired connection via USB-C to HDMI
For users who value maximum picture quality and no delays, wired connectivity is ideal, requiring a USB-C to HDMI adapter.
Connect the adapter to the phone's charging connector, and insert an HDMI cable to the TV at the other end. Switch the signal source on the TV to the appropriate HDMI 1 or HDMI 2 port. The image should appear automatically, as this method does not require complex software configuration.
- 🔌 Buy a quality adapter USB-C on HDMI (preferably supportive 4K).
- 📺 Connect the cable. HDMI adapter-to-television.
- 🔋 Connect the charger to the adapter (to power the phone).
- 🎮 Enjoy the game or movie without delay or buffering.
The main advantage of wired method is stability. No interference from the microwave or the neighbor routers will affect the picture. Also, the phone will charge while viewing if the adapter has an additional USB port for power, which is the only way to broadcast video in 4K HDR resolution without compression.
💡
When buying an adapter, pay attention to HDCP 2.2 support, otherwise content-protected movies from streaming services can be displayed in black screen.
Network solution and configuration
Even when set up correctly, there can be situations where your phone can't see the TV or the connection is constantly broken, most often the problem lies in the router settings or the isolation of customers on the network, check if the "AP Isolation" feature is included in the settings of your Wi-Fi router, as it prevents devices from seeing each other.
If you're late, try rebooting your router and both devices, sometimes forgetting your phone's Wi-Fi network and reconnecting by entering your password, and checking if your router has speed limits for certain devices or traffic prioritization.
In some cases, an antivirus or firewall on a smartphone may block outbound connection for local devices. Try temporarily disabling protection or adding a TV to the list of trusted devices. Make sure that the date and time on both devices are synchronized, as desynchronization can interfere with establishing a secure connection.
💡
The broadcast stability is directly dependent on the quality of the Wi-Fi signal; for 4K video, it is recommended to use a router that supports the Wi-Fi 5 (AC) standard or Wi-Fi 6 (AX) standard.
Use of third-party broadcasting applications
If standard tools don’t work or there aren’t enough features, specialized apps from the Google Play store come to the rescue, programs like Web Video Caster or LocalCast are able to find TVs where others are renting out and support a wide range of formats.
Install the app on your smartphone and follow the instructions of the customizer. Most of them will offer to install the companion app on your Xiaomi TV through the built-in app store, which will ensure the best compatibility and data transfer speed.
Once paired, you can open links to videos in your browser and send them directly to your TV via the Share menu, which is especially convenient for viewing online cinemas that do not have an official Android TV app or block streaming via the standard Chromecast.
