Modern Xiaomi smartphones have powerful displays and excellent multimedia capabilities, but the screen size is often insufficient for a full immersive experience. Image broadcast A large TV allows you to transform your living room into a home theater without the hassle of cables. MIUI (HyperOS) Android users have access to several native and third-party video streaming options.
The main difficulty often lies not in the lack of features, but in the difference in technology used by the TV and phone. Xiaomi Supports both standard Google Cast protocols and proprietary data transfer protocols. Understanding how it works wireless connection will help to avoid delays and desynchronization of sound.
In this article, we'll cover all current connection methods, from built-in system features to specialized apps. You'll learn how to set up a stable connection and troubleshoot common buffering issues. This guide is relevant for Redmi, POCO, and flagship Mi series models.
Preparing equipment and a Wi-Fi network
Before you start the setup, you need to make sure that both devices are in the same network conditions. Router It should correctly distribute traffic between devices without isolating them from each other. The ideal scenario is to use the 5 GHz band, which provides sufficient bandwidth for transmitting 4K video.
Make sure your TV is Smart TV enabled and connected to the same network as your smartphone. Some router models have a "guest network" or client isolation enabled by default, making devices invisible to searchers. Wi-Fi Direct It can also be useful if there is no router, but it is less stable for long sessions.
Update your Xiaomi phone's software to the latest version. Patches that improve protocol compatibility are often added to the system settings. DLNA and Miracast. Go to the "About phone" menu and check for MIUI updates.
⚠️ Attention: If your router uses separate names for 2.4 GHz and 5 GHz networks, make sure both devices are connected to the same frequency, preferably 5 GHz for high-definition video.
For stable operation, it's also recommended to close background apps on your smartphone that consume bandwidth. This will free up bandwidth for the video stream and reduce the likelihood of artifacts appearing on the screen.
Using the built-in Cast function
MIUI and HyperOS already have a built-in screen mirroring utility. This method is based on the Miracast protocol and requires no additional software. It is compatible with most modern Samsung, LG, Sony, and Philips TVs.
To activate the feature, pull down the notification shade and look for the "Cast" icon. If it's not on the main screen, press the quick menu edit button (usually three dots or a pencil) and drag the icon to the active area. Your TV must be in signal reception mode, often called Screen Mirroring or "Screen mirroring".
After the search starts, your phone will display a list of available devices. Select your TV from the list. You may see a connection confirmation prompt on the TV screen—allow it with your remote. Now the image from your phone will be streamed in real time.
- 📱 Make sure your smartphone screen doesn't go dark while you're watching if you're using full-interface mirroring.
- 📺 Some TVs require you to manually select the signal source (Input) on the HDMI port, even with a wireless connection.
- 🔋 Broadcast mode drains battery power significantly, so keep your phone close to a charger.
If the image quality is poor, try lowering the resolution in your phone's display settings before connecting. This will reduce the load on the wireless channel.
Streaming via Google Home and Chromecast
A more advanced and stable way is to use the Google ecosystem. If your TV supports Android TV If you have a built-in Chromecast, this method will provide the best quality. Unlike Miracast, it streams specific content rather than the entire screen, saving resources.
To get started, download and install the application. Google Home from the Play Market. After installation, open the app and find your TV in the list of devices. Click on the device icon and select "Cast my screen."
This method is especially convenient for streaming services like YouTube, Netflix, or online cinemas. You can start a video on your phone, press the "Cast" button within the app, and continue watching on the big screen, using your smartphone as a remote.
☑️ Pre-launch check
It's important to note that Google Home offers minimal signal latency. This makes it suitable even for presentations or simple games. However, for fast-paced games, the wireless connection may still introduce some lag.
Mi Video app and DLNA
Xiaomi's default video player is called Mi Video (or simply "Video") has a built-in DLNA function. This is ideal for viewing local files downloaded to your phone's memory. The DLNA protocol allows you to stream media files directly to the renderer (TV).
Open the video file in the Mi Video app. In the player interface, find the button with a screen image or the "TV" icon. Tap it and select the target device. The TV will begin buffering and playing the file.
The advantage of this method is that the phone acts only as a remote control. You can minimize the app, answer calls, or use other smartphone functions without interrupting playback on the TV. The image quality remains the same, without the compression typical of screen mirroring.
| Characteristic | Miracast (Broadcast) | DLNA (Mi Video) | Chromecast |
|---|---|---|---|
| Transmission type | Screen mirroring | Streaming media | Streaming media |
| Using the phone | View only | Free to use | Free to use |
| Quality | Depends on the signal | Original | Original/Adaptive |
| Battery | High consumption | Low consumption | Low consumption |
If the built-in player isn't detected by the TV, make sure the media center app is running on the TV or the appropriate signal source is selected. In some cases, DLNA may need to be activated in the TV's network settings.
What should I do if Mi Video can't see files?
The video file format may be incompatible with your TV's codecs. In this case, try casting the entire screen via Miracast or installing a third-party player (such as VLC) on your TV that supports more formats.
Third-party applications for complex cases
Sometimes standard Xiaomi and Google tools can't find a device, especially when it comes to older TV models or specific brands. In such cases, universal utilities come to the rescue. One of the most popular solutions is the app Web Video Caster or LocalCast.
These programs can forward a video stream to virtually any DLNA-compatible receiver. The algorithm is simple: you open a video (even from a browser), share it via the "Share" menu, and select the installed app. It will analyze the network and suggest available screens.
A key feature of these apps is their ability to stream content from browsers with copy protection (DRM), although not always successfully. They also often feature a built-in on-the-fly converter, adapting the video format to the TV's capabilities.
⚠️ Attention: Third-party apps may contain ads. For full, unrestricted use, purchasing a premium version is often required, but basic functionality is usually free.
Another option is to use proprietary apps from TV manufacturers. For example, for Samsung this is SmartView, for LG - LG ThinQThey often work more reliably than universal analogs if you have this type of equipment.
Troubleshooting connection and latency issues
Even with proper setup, technical issues may still occur. A common problem is audio and video desynchronization. This can be resolved by rebooting both devices and the router. It's also worth checking to see if your smartphone is overheating, as throttling in Xiaomi's processor can cause image stuttering.
If your phone sees the TV but the connection drops, try statically assigning IP addresses to devices in your router settings. This will prevent addressing conflicts when the DHCP server assigns the same addresses to different devices.
If you see a picture but no sound, check your Android audio output settings. Sometimes the sound remains on the phone and needs to be manually adjusted through the volume menu or Bluetooth/connections settings.
- 🔄 Restart your router if the device list is not updating.
- 📶 If the signal is weak, move closer to the router or use a Wi-Fi repeater.
- 🛡️An antivirus or firewall on your router may be blocking ports for Cast protocols.
Keep in mind that TV software also requires updates. Outdated Smart TV firmware may not support the new encryption standards used by Android 12/13/14.
Frequently Asked Questions (FAQ)
Is it possible to display a Xiaomi screen on a TV without a Wi-Fi router?
Yes, this is possible via Wi-Fi Direct if your TV supports it. You can also use a USB-C to HDMI cable if your Xiaomi model supports video output (usually flagship models with USB 3.1 or higher). In this case, a router is not required; the connection is direct.
Why is only the picture being broadcast but no sound?
Most often, the problem lies with an audio codec that isn't supported by the TV, or with the app settings. Try switching the audio output in your phone's Bluetooth settings (if the TV is connected as an audio device) or use a different player, such as VLC, which can convert audio on the fly.
Does broadcasting affect video quality?
When using Miracast (screen mirroring), quality may be slightly reduced due to real-time stream compression. When using Chromecast or DLNA (Mi Video), the original data stream is transmitted, so quality remains at its highest, depending only on network speed.
How to reduce lag when gaming on TV?
For gaming, it's best to use a wired connection or Wi-Fi 6. Be sure to enable "Game Mode" in your TV settings, which disables unnecessary image post-processing and reduces input lag. Wireless streaming will always have a slight delay.
