With modern technology, you can turn any Smart TV into a powerful multimedia center, using your smartphone as a remote control and content source. Xiaomi owners are in a particularly advantageous position, as the Mi Home ecosystem and the MIUI (or HyperOS) operating system offer native integration between devices, which means that you do not need additional HDMI cables or complex adapters to transfer photos or videos from your phone to the big screen.
The main channel of communication in this process is the wireless WiFi network, which provides data transfer with high speed and minimal latency. However, despite the apparent simplicity, users often face problems of synchronization or do not know which method of replication to choose for a particular type of content.
In this article, we will take a look at all the ways you can connect, from built-in system functions to third-party applications. You will learn how to configure Mi Remote, use the Miracast protocol and broadcast browser content. In addition, we will discuss the subtleties of setting up a router to ensure a stable connection without “twisting” the image.
Equipment preparation and network setup
The first and most critical step is to ensure a single network environment for both devices: Your smartphone and Xiaomi TV must be connected to the same router. If you have a dual-band router, make sure both devices are on the same frequency network (for example, both at 2.4 GHz or both at 5 GHz), although modern routers often combine these networks under the same name.
Check the quality of the WiFi signal on both devices. 4K HDR, A weak signal can cause sound and image to become out of sync or constantly buffered. If the TV is far from the router, consider using a WiFi extender or connecting the TV via a wireless router. LAN-cable, if the model allows.
It's also worth updating the software on both gadgets, and manufacturers often release patches that improve the stability of the DLNA and Cast protocols, on TV this is done through the system settings menu, and on the phone - in the "About the phone".
⚠️ Attention: Use of mobile internet (3G/4G/5G) If you're on a phone with a WiFi TV, you're not going to let the devices see each other.
Use of the built-in Translation function (Miracast)
The most versatile way, which works on most Xiaomi Android smartphones and TVs, is based on Miracast technology, which allows you to duplicate the phone screen to the TV in real time. On Xiaomi TVs, this feature is often built into the system and does not require the installation of additional applications, activating automatically when you search for a device.
To get started, open the control panel (notification curtain) on your smartphone and look for the Translation or Wireless Monitor button. In some versions of MIUI, this item may be hidden in the Connections and Sharing menu. Once activated, the phone will start searching for available devices on the network.
Select your TV from the list. The TV screen may have a request for confirmation of connection, which you need to accept by remote control, then the image from the phone is completely copied to the large screen, which is ideal for showing presentations, photo albums or games.
- 📱 Open your phone settings and go to Connections and Sharing.
- 📺 Click on the Broadcast and turn on the switch.
- 🔗 Wait for the name of your Xiaomi to appear TV on the list and tap on it.
- ✅ Confirm the connection on the TV screen if a request appears.
☑️ Pre-broadcast checks
It is worth noting that when using this method, the phone screen does not go out, which can lead to increased battery consumption. Also, if you fold the application or receive a notification, this will be visible on the TV, since the entire desktop is broadcast.
Broadcasting through the Mi Remote app
Xiaomi smartphone owners can use the Mi Remote app, which is often pre-installed on the system, and this app allows not only to control the TV as a normal remote control via an IR port, but also to act as a media server or screen broadcaster.
Launch an app and add your TV if it hasn't already been added. The TV control interface often has a "Translation" button or arrow screen icon. Clicking on it triggers the search and connection process. This is a good way to do this because the interface is specifically optimized for Xiaomi's hardware.
If the standard app doesn't see the TV, try clearing the app's cache or reinstalling it through the GetApps store.Sometimes Android system restrictions can block Mi Remote from working, requiring additional permissions in privacy settings.
What if Mi Remote can't find TV?
Use of the Chromecast feature built-in type
Many modern Smart TVs from Xiaomi run on Android TV or have built-in support for Google Cast (Chromecast) technology, which allows you to stream content directly from source apps such as YouTube, Netflix or Google Chrome without duplicating the entire screen of the smartphone.
Open the supported app on your phone and find the broadcast icon (the rectangle with the waves in the corner). Select your TV from the list. The advantage of this method is that the phone acts only as a remote control: you can switch to other tasks, lock the screen or exit the application, and the video on the TV will continue to play.
The image quality of Chromecast is often higher than Miracast, as the TV itself downloads the video stream from the Internet using its network module, rather than receiving it through the phone, which reduces the load on the WiFi channel and smartphone.
| Characteristics | Miracast (Translation) | Chromecast (Google Cast) |
|---|---|---|
| Type of transmission | Screen duplication | Streaming content transfer |
| Dependence on the phone | High (screen should be on) | Low (can be blocked) |
| Image quality | Depends on the phone’s WiFi signal | Stable (downloads TV) |
| Battery consumption | High-pitched | Minimum |
💡
For maximum stability when using Chromecast, make sure that the app on your phone (like YouTube) is updated to the latest version via Google Play.
Broadcasting via browser and DLNA
If you want to show the contents of a web page or a file that doesn't open in standard apps, you can use a browser. Google Chrome on Android has a built-in Cast function. Open the browser menu (three dots) and select "Translate...".
You can choose to stream a tab or an entire desktop, which is convenient for viewing videos from sites that do not have an official application, or for showing PDF documents directly from the cloud.
Alternatively, you can use the DLNA protocol, you can install a media server application on your phone (like BubbleUPnP or VLC), and you can run a built-in media player on your TV. From the TV signal source menu, select DLNA and find your phone, which will allow you to view photos and videos stored in your smartphone memory through the TV interface.
The DLNA method is good because it does not require a permanent active screen-to-screen connection, but it is less convenient for navigating the phone's file system from the remote.
Solving Connection Problems
Despite the technology, users may experience errors, and one of the most common problems is that the TV is not visible on the list of available devices, in which case you can try rebooting the router, because the distribution is temporary. IP-address (DHCP) It can break the logical connection between gadgets.
Another problem is desynchronization of sound and video, which often happens when the WiFi channel is overloaded by neighbouring routers, try changing the router's WiFi channel settings or switching to a 5GHz frequency, which is less busy but has a smaller range.
⚠️ Warning: Antivirus apps or firewalls on your phone can block incoming and outgoing connections for your local network. Try temporarily disabling protection for diagnosis.
If the image is twitching or low resolution, check the screen resolution settings in the broadcast menu on the phone. Sometimes automatic determination is not able to cope, and you have to manually set 1920×1080 or 1280×720 to reduce the load on the channel.
💡
Connection stability depends on the quality of the WiFi signal and the absence of interference in the air. If there are frequent interruptions, use a wired connection for the TV.
