Xiaomi’s current smart TVs, powered by Android TV or PatchWall, offer users a wide range of media capabilities. One of the most sought-after features is wirelessly transferring images from a smartphone or tablet to a large screen. This process, often called screen projection or duplication, allows high-resolution video, presentations, photos, and even gameplay. Users value the ability to share content with family or colleagues without the use of complex cables and adapters.
Device synchronization technologies have come a long way in recent years, and wireless connectivity has become the de facto standard for home electronics. However, despite the stated simplicity, the setup process can encounter a number of technical nuances, depending on the phone model and the TV firmware version. Device owners often wonder why their gadgets can’t see each other or why the image is transmitted with a delay. Understanding the basic principles of data protocols will help avoid common errors and enjoy quality images.
In this guide, we will take a look at all the possible ways to organize projection, from built-in system functions to third-party applications. We will look at the features of working with iOS and Android operating systems, since the algorithms for their interaction with the TV differ significantly. We will also pay attention to diagnosing possible problems that may arise when trying to establish a connection. Proper network setting and proper use of software ensure that the entire multimedia system of your home works smoothly.
Preparation of equipment and network infrastructure
The first and most critical condition for successful projection is the proper organization of the local network. In order for your smartphone and Xiaomi TV to exchange heavy streams of video data without buffering, both devices must be on the same subnet. This means that they must be connected to the same router. If you have a dual-band router that supports 2.4 GHz and 5 GHz, it is better to use the 5 GHz bandwidth to maximize channel bandwidth.
It is worth noting that the quality of the Wi-Fi signal directly affects the resolution of the transmitted image. With a weak signal, the system will automatically reduce the image quality to avoid connection breaks, which can lead to compression or pixelation artifacts. Make sure that there are no massive metal obstacles between the router and the TV that can shield radio waves. Ideally, the distance between the access point and the receiver should not exceed 10-15 meters in an apartment setting.
In addition, before you start setting up, it is recommended to check the software of both devices. Xiaomi TVs often release updates that correct errors of wireless communication modules. Go to the settings menu of the TV, select Settings → About device → System update and check for new versions of the software. Up-to-date firmware ensures compatibility with the latest encryption standards and media transmission protocols.
⚠️ Note: Using Guest Network on a router often isolates devices from each other for security reasons.
It's also important to consider the strain on the communication channel, and if at the time of the video transmission, someone in the household starts downloading bulky files or playing high-ping online games, the quality of the projection may suffer. 4K-It is recommended to reserve a channel or broadcast during periods of minimal network activity.
Use of the built-in Chromecast feature
Most modern Xiaomi TVs have built-in support for Google Chromecast built-in. It is the de facto standard for Android devices that allows you to stream content directly from apps, bypassing the need to duplicate the entire screen of a smartphone. This method is most energy efficient, since the main work of decoding video takes on the TV, and the phone acts only as a remote control.
To start the broadcast, make sure that your mobile device has Google Home installed or the corresponding Google Play services are built into the system. Open an application that supports casts (for example, YouTube, Netflix, Spotify), and find the icon with the waves in the corner. Clicking on it, you will see a list of available devices on your network. Select your Xiaomi Mi TV from the list, and the connection will be established automatically.
The advantage of this method is that you can use your phone for other tasks while you're watching, you can switch to messenger, answer a call, or check your email, and it doesn't stop you playing video on the big screen, and Chromecast supports high-quality audio and subtitles, synchronizing them with the video sequence without desynchronizing them.
What if the Chromecast icon doesn’t appear?
It's important to understand the difference between screen duplication and media caste. When you use Chromecast, you send a link to content and the TV downloads it from the Internet, which reduces the load on the smartphone processor and saves battery power. However, for local files stored in the phone's memory, this method may require the use of special players, such as VLC or MX Player, which can send local files to a Chromecast receiver.
Screenplay via Miracast (Wireless Display)
If your job is to show the contents of the screen one-to-one, including smartphone menus, notifications and games that don’t support Chromecast, you’ll need Miracast technology. In Android, it’s often called Translation, Wireless Display, or Smart View (from Samsung), and Xiaomi TVs are great at receiving such a signal by emulating an external monitor.
To activate this mode on a Xiaomi TV, you usually do not need to run individual applications. You just go to the signal sources section (the button with the square and arrow on the remote) and select the source of “Wireless Display” or “Miracast”. On some models with the PatchWall shell, this mode can be called “Projection” and located in the top menu of the applications. Once turned on, the TV will go into the waiting mode for connection.
On an Android smartphone, the algorithm is to lower the notification curtain, find the Translation or Project button. If it's not visible, edit the Quick Settings Panel by adding the widget you want. After scanning the network, the phone will suggest a list of available displays. Select your TV, and in a few seconds the image should appear on the screen.
☑️ Checking before connecting Miracast
Consider that Miracast compresses and transmits images in real time, which puts additional strain on the Wi-Fi module, which can lead to a slight increase in latency (input lag), which is critical for dynamic games, but invisible when watching videos or presentations. Picture resolution is often adapted to the capabilities of the communication channel, so to achieve maximum quality 1080p or 4K requires a very stable signal.
Features of connecting Apple devices (AirPlay)
Apple owners who want to display an image from an iPhone or iPad on a Xiaomi TV may be faced with the issue of protocol compatibility. Traditionally, Apple uses its closed AirPlay standard, which is not supported by Android devices out of the box. However, Xiaomi has implemented AirPlay 2 support in many new TV models, which greatly simplifies the life of users of the Apple ecosystem.
To check if AirPlay is supported on your TV, go to your network or app settings and look for the Apple AirPlay section. If you have one, make sure it is activated. Otherwise, older TV models will require you to install a third-party app from the Google Play Store, such as AirScreen or AirPin, which emulates the AirPlay receiver.
The iOS connection process is as simple as possible thanks to Screen Mirroring. Open Control Point (swipe down from the top right corner on new models or swipe up on old ones), click on the icon with two rectangles and select your Xiaomi TV. The system can request a confirmation code that will appear on the TV screen - type it on your smartphone to pair.
💡
For the best image quality when using AirPlay, make sure that HDR is enabled in your TV settings if your content and screen support this format.
Importantly, when streaming from Apple devices through third-party emulators, you may experience audio and video desynchronization or intermittent connection breaks, due to the peculiarities of real-time stream coding. It is often more effective to use the built-in Translation feature inside the Photo app, which works more stable than full screen duplication, to view photos and videos from the gallery.
Third-party applications for enhanced capabilities
Staffing is sometimes not enough, especially if you want to stream content from applications that block screen recording, or if standard protocols are unstable. In these cases, specialized applications that are installed on both the TV and the smartphone come to the rescue. One of the most popular solutions is a bunch of applications that work on the principle of DLNA or their own transmission protocols.
Xiaomi TVs are great for the Mi Remote app (official from Xiaomi) or universal solutions like LocalCast and AllCast, which allow you to transfer files directly to the user. IP-Installing these programs requires access to the Google Play Store on your TV, which is available on all certified Mi models. TV.
Below is a table of popular applications and their characteristics for the organization of projection:
| Annex | Type of connection | 4K support | Platform |
|---|---|---|---|
| Google Home | Chromecast | Yes. | Android / iOS |
| AirScreen | AirPlay / Miracast | Yes. | Android (TV) |
| LocalCast | DLNA / Chromecast | Yes. | Android / iOS |
| Xiaomi Mi Remote | Wi-Fi Direct | No (photo) | Android / iOS |
When using third-party software, it is important to pay attention to the permissions they request. Apps must have access to the local network and, in some cases, media files to work properly. Remember to update these apps through the Play Market store on your TV, as developers often release patches that improve compatibility with new versions of Android TV.
Diagnostics and problem-solving
Even with the right setup, users can face difficulties, and one of the most common problems is when the TV simply "can't see" the phone. 90% This is done by checking that both devices are connected to the same network (whether the guest network or the range is mixed up). 2.4/5 GHz.It also helps to reboot the router, which resets the cache. DHCP-servers and assigns fresh IP-address.
Another common complaint is poor image quality or constant buffering. This is a direct indicator of channel bandwidth problems. Try moving the router closer to the TV or, if possible, connecting the TV to the router via an Ethernet cable, leaving the phone on Wi-Fi. The wired connection for the receiver (TV) often dramatically improves flow stability.
⚠️ Warning: If the projection is interrupted immediately after starting, check the power saving settings on your smartphone. Aggressive energy saving modes can kill the background data transfer process, considering it inactive.
Also worth mentioning is the problem of desynchronizing sound. If the video is coming and the sound is behind or ahead of the picture, try changing the audio output settings in the TV menu. Switching the format from Auto to PCM or Passthrough often solves the problem of codec compatibility between the phone and TV.
💡
The projection stability of 80% depends on the quality of the Wi-Fi signal and the absence of interference in the air, not only on the power of the TV processor.
In rare cases, you may need to reset your network settings on your TV. → Network and Internet, and select "Forget Network," then reconnect by entering your password. IP-addresses and DNS, which may have been accumulated during the long operation of the device.
