Modern multimedia systems allow you to create full-fledged home theaters using a combination of a smartphone and a large screen. Device owners Xiaomi Often face the need to stream content from a mobile device to a TV to enjoy videos, photos, or games in high definition. Wireless connection via Wi-Fi is the most convenient and popular way to accomplish this task, eliminating unnecessary cables and restrictions in movement.
The setup process may seem complicated at first glance, but the ecosystem Android TV and the shell MIUI (or HyperOS) provide several native tools for a quick start. In this article, we'll cover all available methods in detail, from built-in operating system functions to specialized apps that guarantee a stable video stream.
The key to successful synchronization is proper local network configuration. If your router and both devices are working correctly, you'll be able to display the image in seconds. We'll cover the nuances that beginners often overlook and how to resolve common issues with latency or signal loss.
Basic requirements and equipment preparation
Before you begin setup, you need to make sure all components of your multimedia system are ready to work. A fundamental requirement for any wireless data transfer technology is that the smartphone and TV are in the same network. local networkThis means that both devices must be connected to the same router, either via an Ethernet cable or over the air.
Please pay attention to the frequency range of your Wi-Fi router. For high-quality video transmission, especially in 4K resolution, it is highly recommended to use a network standard 5 GHzIt provides higher throughput and is less susceptible to interference from neighboring networks, which is critical for smooth picture quality.
It's also worth checking the software versions. The TV firmware is outdated. Xiaomi may not support new encryption protocols or codecs used by your smartphone. Go to the TV settings menu and find the section Settings → About TV → System update to check the relevance of the software.
⚠️ Important: If your router supports the "Guest Network" feature, make sure it's disabled for the primary devices. Guest networks often isolate clients from each other, making it physically impossible for the phone to "see" the TV on the local network.
Using Android's built-in Cast feature
operating system Android starting with version 4.2 has a built-in protocol Miracast, which allows you to mirror your screen without installing third-party software. On most smartphones Xiaomi This feature is called "Broadcast" or "Wireless Monitor." It's deeply embedded in the system and can be activated through the notification bar.
To start the process, pull down the notification shade on your phone and find the "Broadcast" icon. If it's not visible, tap the pencil or three dots to edit the panel and add this item. Once activated, the phone will begin searching for available receivers within range.
☑️ Check before starting the broadcast
When the connection request appears on the TV screen or your phone's name appears in the list of devices, simply select it. The image from your mobile device will instantly appear on the big screen. It's important to understand that in this mode, everything that happens on your smartphone's screen is mirrored, including notifications and system sounds.
Some models Xiaomi may require manual signal activation. To do this, press the signal source setting button on the TV remote (usually a square with an arrow) and select "Wireless Display" or "Miracast." Only after the standby screen appears on the TV will the phone be able to detect it.
Google Chromecast technology for content streaming
Unlike full screen duplication, the technology Chromecast Google Cast allows you to stream specific content from apps directly to your TV. This is a more energy-efficient method, as the phone only acts as a remote control, while the TV downloads the video stream directly from the internet.
For this method to work on TV Xiaomi with the operating system Android TV Chromecast is built-in by default. If you have an older model with PatchWall, you may need to install a special receiving app, although modern models support this protocol natively.
To start broadcasting, open a supported app on your smartphone, such as YouTube, Netflix or VK VideoFind the rectangle icon with waves in the corner (the Cast icon) and click it. Select your TV from the list. Xiaomi.
What is the difference between Miracast and Chromecast?
Miracast creates a direct connection and broadcasts every pixel of the phone's screen in real time, which can drain battery life. Chromecast instructs the TV to play content from the internet, freeing up the phone and often providing better quality and stability.
The advantage of this method is the ability to use your phone for other tasks while watching a movie. You can switch to a messenger or browser, and playback on your TV will not be interrupted. Picture quality is often higher, as the TV decodes the video itself using its powerful processor.
Mi Remote app and Mi Home ecosystem
Company Xiaomi developed my own application Mi Remote, which turns your smartphone into a universal remote control. While its primary function is to control channels and volume, it also allows you to stream media files to your TV. This is especially useful for older TV models from the brand.
Download the app Mi Remote from the store Google Play or GetAppsOnce launched, the app will automatically scan the network and prompt you to add your TV. Follow the on-screen instructions, entering the confirmation code if it appears on the TV display.
To transfer a photo or video, open the desired file in your gallery or video player, click the "Send" or "Cast" button, and select your TV from the list of Mi devices. The system will create a temporary data channel.
| Connection method | Latency | Image quality | Battery consumption |
|---|---|---|---|
| Miracast (Broadcast) | Low (50-100 ms) | Depends on Wi-Fi signal | High |
| Chromecast | Minimum | Maximum (up to 4K HDR) | Short |
| Casting from apps | Absent | Original quality | Minimum |
| DLNA (via player) | No (local file) | No losses | Average |
Using proprietary apps often provides access to additional features, such as mouse control from your phone's screen or a keyboard for text entry in search on your TV. This simplifies navigation through complex Smart TV menus.
Streaming via third-party players and DLNA
If standard methods don't work or you need to play a video file of a certain format stored in your phone's memory, multimedia players with support come to the rescue. DLNA. The leaders in this field are applications VLC for Android And MX Player.
Install the chosen player on your smartphone. Open the video file you want to watch. In the playback control menu (usually three dots or a special icon), find "Renderer," "Cast," or "Playback on Device."
The app will scan the network and find your TV. XiaomiAfter selecting a device, the video stream will be transmitted to the TV. This method is ideal for viewing personal archives, as the player can often recode audio or subtitles on the fly if the TV doesn't understand them.
⚠️ Note: When transferring large files (over 10 GB) via Wi-Fi, buffering may occur. In these cases, it's best to use a 5 GHz local network or connect your phone directly to the TV via USB, if your TV model supports it.
Another advantage of DLNA players is their support for a wide range of audio and video codecs. Built-in Android tools may not be able to play files of this format. MKV with a path DTS, and a third-party player can easily handle this task, broadcasting the finished image to the screen.
Troubleshooting and connection optimization
Despite the simplicity of the technology, users may encounter problems: the TV doesn't detect the phone, the image flickers, or there's no sound. Most often, the cause lies in the router's security settings or temporary network hardware failures.
Try rebooting your router by completely unplugging it for 10-15 seconds. This will clear the network cache and redistribute channels, which often resolves the "invisible" device issue. Also, make sure AP Isolation is not enabled on your router.
For gamers planning to stream games, input lag is critical. In this case, wireless methods may not be effective enough. However, if there are no alternatives, move the router as close to the reception area as possible and close any background apps on your phone that consume data.
If the problem persists, check the date and time settings on both devices. Time misalignment can lead to security certificate errors, preventing the handshake between the devices.
Frequently Asked Questions (FAQ)
Why doesn't my Xiaomi TV see my phone in the list of devices for streaming?
The most likely cause is that the devices are connected to different networks (for example, one to 2.4 GHz, the other to 5 GHz, and the router is isolating them) or a guest network is enabled. Also, check if your phone's antivirus software is blocking local connections.
Is it possible to display a screen on a TV without a Wi-Fi router?
Yes, some phone and TV models support Wi-Fi Direct technology. This technology allows devices to connect directly to each other, creating their own network. This feature is usually listed as "Wi-Fi Direct" in your TV settings.
Does the sound stream to the TV when the phone screen is off?
When using Chromecast or YouTube Cast, yes, audio will continue to play even if the phone's screen is off. When using Miracast (full screen mirroring), audio will still be transmitted, but the phone must remain active, which drains the battery.
How to improve the quality of a picture if it is blurry?
Make sure the output resolution on your phone matches your TV's resolution (usually 1920x1080 or 3840x2160). A weak Wi-Fi signal may also automatically reduce the stream quality to prevent tearing.
