Owners of modern Xiaomi equipment often face the desire to transfer an image from a large screen to a mobile device, this may be necessary to save important frames from a movie, demonstrate the settings of a smart home, or simply to easily view content in another room. The Mi Home ecosystem and the MIUI operating system (HyperOS) offer many built-in tools to accomplish this task.
The process of transferring video streams depends on the type of content and specifications of both devices. Xiaomi Redmi or Poco smartphones have powerful codecs that can decode streaming video in high resolution.
In this article, we will look at all the current ways of connecting, from standard protocols to specialized applications, you will learn how to avoid delays and desynchronization of sound, as well as what nuances the Translation feature hides in different versions of firmware.
Technical requirements and equipment preparation
Before you start setting up, you need to make sure your hardware meets the minimum requirements for stable data protocols. The key is whether you have Wi-Fi Direct or DLNA support on both devices. Most modern TVs, whether they are Android TV, Tizen or WebOS, have this feature out of the box.
Note the version of your smartphone operating system. The MIUI version of Android at least 9.0 is required to work correctly. Older versions may not support the necessary codecs or encryption protocols, which will lead to permanent connection breaks.
⚠️ Warning: Make sure the router distributes the network at 5GHz. When using the 2.4GHz band, there may be severe delays and image artifacts due to low channel bandwidth.
It’s also worth checking if device detection is enabled in router settings, and sometimes AP Isolation can prevent the phone and TV from connecting directly even if they’re connected to the same network.
☑️ Checking the broadcast readiness
Use of the built-in Translation function in MIUI
The fastest way to display an image is to use the native system tool, which is called Translation or Cast on Xiaomi and Redmi smartphones. To start, lower the notification curtain and find the corresponding icon. If it is not available quickly, click on a pencil or edit button to add a widget to the screen.
Once activated, the system will start searching for available devices on the local network. The TV screen may request permission to connect. Depending on the TV model, you may need to click the "Confirm" button on the remote control. The Miracast protocol, used by default, provides image transfer without compression, which guarantees high quality images.
If the search doesn't work, try rebooting the Wi-Fi module on your phone. Sometimes the wireless driver freezes and stops seeing neighboring devices, and switching visibility mode in connection settings also helps.
💡
If the TV doesn’t appear in the list, try clicking on the TV remote to click “Input” or “Source” and select Screen Mirroring, “Miracast” or “Wireless demo” mode.
Importantly, when streaming through Miracast, the phone’s screen is completely duplicated, meaning that incoming notifications, messages and system sounds will be visible and audible on the big screen. For privacy, it’s better to turn on Do Not Disturb mode before you start a session.
Broadcasting via Google Home and Chromecast
For Android TVs or with Chromecast built-in, the most stable option is to use the Google Home app, which allows you to broadcast not only the screen, but also individual browser tabs or media files from the gallery.
Install the Google Home app from the Play Market if it hasn't already been installed. Open the app and wait for it to find your TV. The device list will show your TV icon. Click on it to open the control panel.
- 📺 Click the “Translate Screen” button at the bottom of the application interface.
- 📡 Select your TV from the list of devices offered.
- 🔒 Confirm the connection if a code or request appears on the TV screen.
- 🎬 Open any content on your phone and it will show up on your TV.
The advantage of this method is that it supports the H.265 codec, which allows you to stream video in 4K resolution with minimal load on the smartphone processor.
| Parameter | Miracast (Integrated) | Google Chromecast | DLNA |
|---|---|---|---|
| Type of transmission | Screen duplication | Streaming transmission | Media files only |
| Delay. | Low. | Medium | Absent. |
| Battery consumption | High-pitched | Medium. | Low. |
| Support for DRM | Partial | Full (Widevine) | No. |
Broadcasting of protected content (Netflix, YouTube, Movie Search)
When trying to stream video from streaming services, users often encounter a black screen, this is due to HDCP digital content protection technology. Simple screen duplication (Screen Mirroring) cannot transmit a secure signal, since the security system blocks image capture.
To solve this problem, you need to use the built-in "Cast" function inside the app itself: Open YouTube or Netflix on your phone, find the rectangle icon with waves in the corner of the video. Click on it and select your TV.
In this case, the phone acts only as a remote control, and the video stream is downloaded by the TV directly from the Internet, which frees up the resources of the smartphone and allows you to use it for other tasks while watching a movie.
⚠️ Warning: If the video doesn’t start when using the Cast button inside the app, check if the phone is on. VPN. Services often block broadcasts to external devices when they change IP-address.
Some older TVs may not support newer versions of the security protocols, so the only option is to use an external media player, such as the Chromecast. 4K Apple TV, plugged-in HDMI-port.
Use of third-party broadcasting applications
If standard methods don’t work or advanced features are needed, specialized apps from the Google Play store come to the rescue, allowing you to stream the screen even to devices that don’t formally support Miracast.
One of the most popular solutions is the Web Video Caster app, which allows you to open web pages with video on your phone and send a direct stream to your TV without buffering on your smartphone, which is especially true for viewing online cinemas through your browser.
Another powerful tool is AirScreen or ApowerMirror, which often requires you to install a server part on your TV (if it's an Android TV) or use a proprietary receiver, and they provide the ability to control your phone from a remote TV, which is convenient for gaming.
Secrets of AirPlay on Android
It should be noted that free versions of such programs often contain advertising and have a session time limit. For permanent use, it is advisable to consider buying a licensed version or using paid counterparts.
Connection problems and their solution
The most common problem is desynchronizing audio and video streams, which can be ahead of the picture or behind it by a few seconds, most often treated by cleaning the application cache or restarting a router that can not cope with packet routing.
Another common situation is that the phone sees the TV, but the connection is reset in a few seconds. IP-Addresses or outdated Wi-Fi drivers. Try the Wi-Fi settings on your phone to select "Forget Network" and then reconnect by entering your password.
- 🔄 Restart the router and both devices (TV and phone).
- 📡 Make sure that the router does not include filtering by MAC-address.
- 📶 Get closer to the router to eliminate signal problems.
- ⚙️ Reset your network settings on your phone through the Connections menu».
If nothing helps, it may be the antivirus software or firewall installed on your smartphone, so try to temporarily disable the protection and check the connection.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the smartphone processor.
