Modern users are rarely content with watching content on a small smartphone screen. Often, you need to show photos to friends on the big screen or watch a high-resolution film without straining your eyes. Owners of the Xiaomi and MIUI ecosystem have several built-in and third-party tools to accomplish this task without using extra wires.
Wireless technology allows you to instantly synchronize your mobile device with your TV if both devices are connected to the same network. The setup process may seem complicated only at first glance, but the algorithm of actions is quite simple and logical. In this article, we will discuss in detail all available methods, from standard functions to specialized software.
We will look at the nuances of Miracast and DLNA protocols, as well as the features of using Google Chromecast in the HyperOS shell. Understanding the principles of these technologies will help you avoid delays and desynchronization of sound, followed by a step-by-step guide for various use cases.
Preparation of equipment and network for stable operation
Before you start setting up the software, you need to make sure that the hardware is working correctly. The first and most critical condition is that both devices are on the same LAN. If your router is sending signals at 2.4 GHz and 5 GHz, make sure that both your smartphone and TV are connected to the same range.
Connection stability is directly dependent on the power of the Wi-Fi signal. A weak signal can cause artifacts to appear in the image or a complete disconnection during viewing. It is recommended to bring the phone closer to the router or TV during the initial setup and pairing stage.
It's also worth checking out software updates on both devices. Manufacturers often release patches that improve the compatibility of broadcast protocols. Go to your TV settings and find the system section to check for new firmware.
⚠️ Note: If your router has a Guest Network or Customer Isolation feature AP», Make sure it's offline, otherwise devices won't be able to see each other on the network, even when they're in the same band.
Use of the built-in Translation function in MIUI and HyperOS
The fastest way to display a picture is to use Xiaomi’s native feature, called “Translation” or “Wireless display,” which is based on Miracast technology and does not require additional software. The algorithm is extremely simple and available out of the box on most models.
To start, lower the notification curtain down and find an icon called Translation. If it's not on the first screen, click on a pencil or three menu editing dots and add the widget you want, and when activated, the phone will start searching for available devices within range of the network.
☑️ Checking before connection
When the search is complete, the name of your TV will appear in the list. Click on it, and in a few seconds the image from the smartphone screen will appear on the large display. It is important to note that in this mode the screens are completely duplicated, and any notifications that come to the phone will be visible to all viewers.
The quality of the image being transmitted depends on the loading of the wireless channel. There may be a slight delay when watching dynamic video, which is the norm for Miracast technology.
Streaming through Google Home and Chromecast built-in
If your TV supports Android TV or has a built-in Chromecast module, you can use a more advanced transmission method. Unlike simple screen broadcasting, here content can be transferred directly from the server to the TV, which reduces the load on the smartphone.
To implement this method, you will need the Google Home app, which you can download from the Play Market Store. Once installed, open the program and wait for it to find your TV. Make sure you use the same Google account as you do on your TV if you need authorization.
| Parameter | Broadcast (Miracast) | Google Cast (Chromecast) | DLNA (Media Server) |
|---|---|---|---|
| Type of transmission | Full screen duplication | Streaming content transfer | File transfer |
| Dependence on the phone | High (screen should be on) | Low (you can fold the application) | Medium |
| Delay (Latency) | There's a noticeable delay. | Minimum | Absent. |
| Battery consumption | High-pitched | Moderate. | Low. |
In the Google Home app, select your TV and click on Translate screen. The system will warn you that the sound and image will be broadcast on TV. Confirm the action, and the connection process will begin. This method often provides a more stable picture in high resolution 1080p and even 4K.
💡
To save battery power during a long stream through Google Home, you can connect your phone to the charger, since the process of encoding video is energy-consuming.
Setup DLNA via Mi Video app and Gallery
If your goal is not to duplicate the screen, but simply play a video file or show photos stored in the phone’s memory, the best way to use the DLNA protocol is to use the standard “Video” (Mi Video) and “Gallery” apps on Xiaomi smartphones.
Open the video file you want in the Mi Video player. In the playback interface, find an icon that resembles a rectangle with waves (usually in the corner). When you click on it, you'll see a list of available devices. Select your TV, and playback will begin directly on it.
The advantage of this is that the phone is just a remote control, so you can fold the app, answer the phone, or even lock the screen, and the video on the TV will continue to go without interruption, which is especially useful when watching long movies.
⚠️ Attention: Protocol DLNA If you don't have subtitles on your TV when playing a movie via Mi Video, try embedding them in a video file in advance or using a full screen duplication method.
Third-party applications for complex cases
In situations where the built-in hardware is not working or the TV is old without Smart TV support, third-party solutions come to the rescue, and the market offers many applications that can turn any TV with an HDMI port into a multimedia center.
One popular solution is to use a bundle of server applications and clients, such as BubbleUPnP or LocalCast, which allows you to stream content to almost any device, and there are solutions that require you to install the server part on a PC connected to a TV.
- 📺 Web Video Caster - great for broadcasting videos from browsers, is able to stream video from sites immediately to TV.
- 📱 TeamViewer Remote Control – allows you not only to see the screen, but also to control the phone from the TV (if the appropriate host is installed), useful for presentations.
- 🎮 ApowerMirror is a powerful tool for gamers and streamers, allowing you to broadcast a screen with minimal latency and high bitrate.
When using third-party software, pay attention to the availability of advertising in free versions. Often, the functionality can be limited in terms of session time or image quality. Paid versions usually remove these restrictions and provide priority support for codecs.
Why can’t the search for devices work?
Solving Connection Problems
Even if you set it up properly, you can have technical failures. The most common problem is that the phone just doesn't see the TV on the list of available devices. In this case, try rebooting both the gadget and the router, which is a trivial but effective action that clears the cache of network services.
Another reason could be an outdated version of Wi-Fi drivers or incompatibility of encryption standards. Make sure both devices use the same type of security, such as WPA2-PSK. Mixed router modes sometimes cause conflicts.
If the image is broadcasting but interrupted or stuttered, try lowering the output resolution in your broadcast settings, disabling other devices that are actively consuming traffic on your network can also help, and the stability of your Wi-Fi channel is a key success factor.
💡
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).
