Modern televisions Xiaomi Mi TV and prefixes Android TV Box While we've transformed a regular screen into a multimedia center, there's often a need to display content directly from a mobile device. Streaming video from a phone to a TV via Wi-Fi isn't just copying files; it's synchronizing streaming content in real time. Users often confuse streaming technologies, relying on Bluetooth or wired methods, while wireless protocols offer maximum convenience.
There are several proven ways to implement this feature, each of which has its own characteristics depending on the operating system of your smartphone. Wireless broadcasting It allows you to display photos, videos from your gallery, or even a mobile app screen on a large display without lag. It's important to ensure both devices are on the same local network, which is a basic requirement for stable operation.
In this guide, we'll cover all the relevant methods, from built-in system functions to third-party apps. You'll learn how to set up Miracast for a full screen mirror copy or use the protocol DLNA to play your media library. The right method depends on what you want to display: a game interface, a movie from an online cinema, or a family album.
Preparing equipment and network
Before setting up, there are a few preparatory steps that beginners often overlook. The most critical requirement is that both devices must be connected to the same Wi-Fi network. If your router broadcasts signals on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), make sure both your phone and TV are connected to one of them, preferably 5 GHz for high throughput.
Check the version of the operating system on your Xiaomi TVOutdated software may not support new codecs or security protocols. Go to your TV's settings menu and select Settings → About TV → System update and search for new versions. This often resolves issues with the device not appearing in the list of available devices.
⚠️ Note: If your router is configured in AP Isolation mode, devices will not see each other on the local network, even if they are in the same band. This feature is often enabled on guest networks or in offices for security reasons.
It's also worth paying attention to your smartphone's battery. Streaming high-definition video, especially 4K, uses significant power and heats up the processor. It's recommended to connect your phone to a charger if you plan on watching for long periods. Connection stability directly depends on the quality of the Wi-Fi signal, so try to avoid creating physical obstacles between the router and the receiver.
☑️ Check before connection
Using Chromecast Built-in
Most TVs Xiaomi run on an operating system Android TV, which has built-in support for the technology Google Cast (Chromecast built-in). This is the easiest and most reliable way to stream content from supported apps like YouTube, Netflix, Vimeo, or Yandex.Kino. You don't need to search for additional settings in the TV menu; everything works within the apps.
To start playing, open the video on your smartphone and look for the distinctive rectangle icon with waves in the corner of the screen. Once you click it, the system will prompt you to select a device. If you see the name of your TV, Xiaomi If you're looking for a video in the list, simply tap it. The video will start playing on your TV, and you can use your phone as a remote control or set it aside.
It's important to understand the difference between streaming and mirroring. When using Chromecast, your phone only sends a link to the video stream to your TV, which the TV downloads automatically. This means picture quality isn't dependent on your smartphone's power, and battery drain is minimal. However, if the app doesn't support Cast, this method won't work, and you'll have to resort to other options.
Why does the video lag when broadcasting?
Lag is often caused by Wi-Fi congestion. If the router is simultaneously distributing internet to other devices or is located far away, buffering is inevitable. Try lowering the video quality in the app settings or moving the router closer to the TV.
Screencasting via Miracast (Wireless Display)
If you need to show the entire screen content, including the desktop, settings menu, or a game that doesn't have built-in Cast support, you'll need technology MiracastOn Xiaomi devices, this feature is often called "Wireless Display" or "Cast." Unlike Chromecast, it directly encodes and transmits the video stream from the smartphone screen to the TV in real time.
On TV Xiaomi With Android TV, you don't usually need to launch a separate app; the feature is built into the system. However, on some models, you may need to open an app. Wireless Display or similar to put the TV into connection standby mode. After that, on your Android smartphone, go to Settings, find the section Connected devices → Connect to a device → Wireless projection (names may differ depending on the MIUI or HyperOS shell).
After searching for devices, select your TV from the list. A connection permission prompt may appear on the TV screen, which you'll need to confirm with the remote. It's worth noting that when using Miracast, your phone doesn't turn off the screen, which can cause screen burn-in if you're left with a static image for extended periods. There may also be a slight delay between actions on your phone and the display on your TV, which is normal for this technology.
| Characteristic | Chromecast (Google Cast) | Miracast (Broadcast) |
|---|---|---|
| Operating principle | Broadcasting a link to a stream | Screen mirroring |
| Impact on battery | Minimum | High |
| Image quality | Up to 4K HDR (depending on app) | Depends on Wi-Fi signal |
| Work in the background | Possible | The phone screen is active |
Using the Google Home app
If the standard system tools do not find the TV or work unstably, the official application Google Home becomes an indispensable assistant. It's a universal remote control for the entire smart home ecosystem, also handling setup and broadcast functions. The app is available for Android and iOS, making it a cross-platform solution.
After installation and authorization in your Google account, the application will automatically scan the network and find your Xiaomi TVBy clicking on the TV icon, you'll see the "Cast Screen" button. This method is often more stable than the built-in tools of some smartphone manufacturers, as it uses Google's native protocols.
The unique feature of Google Home is that it allows you to control not only the streaming but also the volume and even launch apps on the TV directly from your phone. This turns your smartphone into a fully-fledged touch remote. However, it's important to keep in mind that the app must be running and active during the connection to maintain a stable connection.
Third-party apps for DLNA and streaming
In situations where standard protocols don't support the required video file format or you want to play local content with complex encoding, third-party solutions come to the rescue. Protocol DLNA (Digital Living Network Alliance) allows you to transfer media files between devices on the same network without screen mirroring. In this case, the TV acts as a renderer and the phone as a server.
One of the most popular applications is VLC for Android or BubbleUPnPIn VLC, simply open a video file, click the menu, and select "Play with DLNA renderer." The app will scan the network and prompt you to select your Xiaomi TVThe advantage of this method is that the phone acts only as a remote control, while the TV handles the decoding, reducing the load on the mobile device.
Another option is to use aggregator apps such as Web Video CasterThey allow you to open videos on websites in your phone's browser and stream them directly to your TV, bypassing mobile browser limitations. This is especially useful for viewing content from web resources that don't have an official Android TV app.
⚠️ Warning: When using third-party apps, make sure you download them from official stores (Google Play, App Store). Unofficial versions may contain malicious code or may not work reliably with newer versions of Android.
Troubleshooting and error recovery
Despite the simplicity of the technology, users often encounter problems: the TV doesn't detect the phone, the video is choppy, or there's no sound. One common cause is using different Wi-Fi frequencies. If the router broadcasts 2.4 GHz and 5 GHz networks under the same name, the devices may be assigned to different bands, blocking detection. Try temporarily separating the networks in the router settings.
Another common issue is an antivirus or firewall on your smartphone blocking local connections. Check your antivirus software's security settings and add the local network to the trusted list. You should also reboot your router, as an overflowing ARP address table can prevent new connections.
If there's sound but no video (or vice versa), the problem lies with the codecs. The TV may not support the audio format the phone is broadcasting. In this case, switching the audio output settings in the source app to the format Stereo instead of Surround or PassthroughUpdating your TV's firmware also often fixes compatibility issues.
Frequently Asked Questions (FAQ)
Is it possible to stream video from iPhone to Xiaomi TV?
Yes, it's possible. Since Xiaomi TVs run Android TV, they don't support AirPlay natively. However, you can install an app. AirScreen or AirPin from the Google Play Store to your TV. Once you launch this app, your TV will be visible to the iPhone's Screen Mirroring feature. Casting through the Google Home app is also possible, provided the content is supported.
Why does image quality drop when streaming via Wi-Fi?
Quality degrades due to limited bandwidth. High-definition video (4K) requires a stable data transfer rate. If the Wi-Fi signal is weak or the channel is busy with other devices, the system automatically reduces the bitrate to prevent buffering. Solution: Use a router that supports 5 GHz and stay closer to it.
Do you need internet to stream video via Wi-Fi?
Miracast and DLNA don't require global internet access; a local network between the router and devices is sufficient. However, Google Cast (Chromecast) and streaming services (YouTube, Netflix) do require internet access, as the TV downloads content automatically.
How to reduce lag when playing games on your phone on TV?
Input lag is inevitable with a wireless connection, but it can be minimized. Enable "Game Mode" on your TV, which disables image post-processing. Also, make sure your phone is connected to a 5 GHz network rather than 2.4 GHz, as the latter is more susceptible to interference.
