Xiaomi’s modern smartphones and TVs enable a single multimedia ecosystem where content from a small screen instantly appears on a large diagonal, especially for viewing photos, videos or showing presentations to family or colleagues, and the process of synchronizing devices has become much easier thanks to the introduction of Miracast protocols and the development of its own MIUI shell (HyperOS).
In this article, we will take a detailed look at all available broadcast methods, from standard wireless solutions to wired connections through the Internet. HDMI-You'll learn about the nuances of Translation, the features of using the Mi Remote app, and how to fix typical device detection problems. Understanding these processes will allow you to maximize the potential of your technology.
Before you start setting up, make sure that both devices are working correctly and have up-to-date software versions, a basic requirement that often leads to the inability to establish a connection, and in some cases, you may need to manually configure the network or reset your connection settings.
Connection requirements and device preparation
For successful wireless broadcasting, it is critical that both gadgets are on the same local network.This means that the Xiaomi smartphone and Smart TV must be connected to the same router, whether via Wi-Fi or an Ethernet cable. If you use a guest network or 2.4 GHz band on one device and 5 GHz band on the other with customer isolation, the search may not yield results.
Check the version of the operating system on your TV. Older models with Android TV versions below 9.0 or proprietary PatchWall systems may require an update to the built-in broadcast module. On your smartphone, you should also check for updates in the Settings → About Phone section. Sometimes the Translation feature is hidden in the menu and requires activation through additional settings.
Make sure that the TV is on, and depending on the TV model, it can be called Miracast, Screen Mirroring, Wireless Display, or simply Transplay, and without activating this mode, the TV won't be visible on the smartphone's list of available devices, even if the Wi-Fi is set up correctly.
⚠️ Note: When using public Wi-Fi networks (in hotels, cafes), the broadcast may be blocked by the network administrator due to a ban on the exchange of traffic between customers (AP In such cases, wireless connection is not possible.
Connection stability is directly dependent on signal quality. If the router is far away or behind thick walls, delays (lags) and sound desynchronization are possible. To achieve the best image quality in 1080p or 4K resolution, it is recommended to minimize the distance between the devices and the access point.
Use of the built-in Translation function in MIUI
The fastest and most common way to display an image is to use the MIUI shell tool, which requires no third-party applications and works on most modern TVs that support Miracast protocol.
To start, open the control center on your smartphone. Depending on the firmware version, this is done by swiping down from the top right or top left corner of the screen. Find an icon called "Cast." If the icon is not in quick access, click on a pencil or three dots to edit the menu and add this element.
Once activated, the phone will start searching for available devices, and in the list that appears, you will see the name of your Xiaomi TV, clicking on it initiates a connection, and a request for permission to connect may appear on the TV screen, which must be confirmed by the remote control.
You can switch between apps, answer calls, or check messages, and all of this will be displayed on a large screen, but you should consider that in this mode, the smartphone consumes more power, so battery life can significantly decrease, and it is recommended to keep the device charged or connect it to a power bank.
☑️ Preparation for broadcast
If you want to change the quality settings, tap the gear in the broadcast window. You can select the resolution and frame rate here. You can choose the high refresh rate mode to watch dynamic videos or games, so you can avoid blurring the picture.
Broadcasting through the Mi Remote app
The second effective way that is often overlooked is to use the Mi Remote app, which allows you not only to control the TV as a remote control, but also to broadcast the contents of the screen, which is especially useful if the standard Translation function is unstable for some reason.
Run the Mi Remote app on your smartphone. If your TV hasn't been added yet, click + and select a model from the list or use automatic search. After successful pairing, go to the TV control interface. In the upper right corner or in the tool menu, find the Cast button.
The app will suggest you choose to work mode: you can broadcast the entire screen of your smartphone or only the content of a particular application (for example, a video player), the second option often provides better picture quality, since the video is decoding by the TV, and the phone acts only as a remote control.
| Parameter | Translation function (MIUI) | Mi Remote appendix | HDMI wired |
|---|---|---|---|
| Signal delay | Medium (depending on Wi-Fi) | Low (at DLNA) | Absent. |
| Image quality | Good (compression) | Excellent (flow) | Maximum. |
| Battery consumption | High-pitched | Medium. | Low (charging in) |
| Difficulty setting up | Minimum | Medium | Adapter required |
Using Mi Remote gives you more control over the process, you can control volume, switch signal sources, and even install apps on your TV directly from your smartphone, making Xiaomi Phone + Xiaomi TV one of the most convenient bundles on the market.
Broadcasting content from apps (YouTube, Netflix)
The apps themselves are also featured in the streaming process, with services like YouTube, Netflix, IVi or Okko using Google Cast (Chromecast built-in) technology, which is the most energy-efficient way to do this, because the video is downloaded directly by the TV and the phone only sets commands.
Open the video on your smartphone and find the Chromecast icon in the corner of the player. Click on it and select your Xiaomi TV from the list. The video will run on the big screen, and the phone can be used for other tasks or even blocked.
The main advantage of this method is that there is no load on the smartphone processor and minimal traffic consumption of the mobile network if the video is buffered, and the image quality is often higher than with mirror display of the screen, since the original video stream is transmitted.
⚠️ Note: Some applications with protected content (DRM) can block the screen broadcast through the function "Translation» MIUI, In such cases, only use the built-in Cast button inside the app itself.
If the broadcast icon doesn't appear, make sure the apps on your phone and TV are updated to the latest versions. Also check that Google accounts on devices match, although this isn't always a strict requirement for your LAN to work.
Why is there no sound when broadcasting?
Wired connection via HDMI and USB-C
For users who want maximum image quality without compression and delays, or for those who have unstable Wi-Fi, there is a wired option. It requires a special adapter (adapter) from USB Type-C to HDMI. Not all Xiaomi smartphones support video output through the charging port.
Support for video output is usually available on flagship Mi and Xiaomi models (e.g. Mi 10, Mi 11, Xiaomi 13/14 Pro) that come with a USB 3.0 port or higher. Budget Redmi and POCO models often have a USB 2.0 port that doesn't transmit a video signal, even with an adapter. Be sure to check the specifications of your model before buying a cable.
The connection is simple: insert the adapter into the phone connector, connect HDMI-cable from adapter to TV and select the appropriate signal source (HDMI 1, HDMI 2) remote TV: the image will appear automatically, often in screen expansion or full mirror mode.
💡
Use adapters with an additional USB port to power your phone so that it doesn’t run out during a long broadcast, as video output consumes a lot of power.
This method is ideal for gaming, as there is virtually no input lag. You can play mobile shooters or big-screen racing with minimal latency, which is impossible to achieve over a wireless network.
Solving and eliminating errors
Despite the simplicity of the technology, users often face problems, the most common is that the TV is not on the list of devices. First of all, double-check the Wi-Fi network. Make sure that the router does not include AP Isolation, which prevents devices from seeing each other.
The second common scenario is a discontinuous image or audio synchrony, which is a sign of a weak Wi-Fi signal. Try switching the router to a less loaded channel or bringing the phone closer to the router, and rebooting the Wi-Fi module on both devices also helps.
If nothing works, try resetting your network settings on your TV or updating the Wireless Display app through the TV app store. Sometimes a WPA2/WPA3 security protocol conflict can interfere with the connection.
💡
90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
