Modern Xiaomi smartphones feature powerful displays and high-quality cameras, making viewing content a pleasure. However, for family viewing of photos, videos, or presentations, a 6-7-inch screen is often insufficient. Fortunately, wireless data transfer technology makes it easy to stream images from your device to a large TV screen using only your home Wi-Fi network. This eliminates the need for HDMI cables or special adapters.
The connection process may vary depending on your TV model and operating system version. MIUI or HyperOS, installed on your smartphone. In this article, we'll cover all available methods in detail, from built-in features to third-party utilities, that guarantee a stable signal. You'll learn how to set up your broadcast to maintain high image quality and minimize latency.
First of all, make sure that both devices - and your smartphone Xiaomi, and Smart TV are connected to the same wireless network. This is a fundamental requirement for most media transfer protocols to work. If your router broadcasts the network on both 2.4 GHz and 5 GHz frequencies, try connecting your gadgets to one of them, preferably the faster one. 5 GHzto avoid interruptions when playing 4K videos.
Using the built-in "Cast" feature in MIUI and HyperOS
Xiaomi operating systems already include the necessary screen mirroring functionality. You don't need to download additional apps if your TV supports Miracast or Wi-Fi Direct. This method allows you to fully mirror your smartphone's display, including the desktop, menu, and any open apps.
To activate the feature, pull down the notification shade and find the "Broadcast" icon. If the icon is hidden, click the pencil or edit button in the top corner of the quick access menu and drag it to the active panel. Once launched, it will search for available devices within range of your local network.
⚠️ Note: Some older TV models may not appear in the list even if they support Miracast. In this case, try temporarily disabling AP Isolation on your router in the wireless network settings.
Once your TV appears in the list, click on its name. A connection confirmation prompt may appear on the TV screen, which you'll need to confirm with the remote. After that, the image from your phone will appear. Xiaomi will appear on the big screen. The quality of the transmission depends on the signal strength. Wi-Fi and channel congestion.
It's worth noting that when casting the full screen, the smartphone may heat up faster than usual, as the processor and communication module are under load. If you plan to watch for long periods, it's recommended to disable power saving for system processes or charge the phone.
Streaming via Google Home and Chromecast
If your TV runs Android TV or has built-in Chromecast support, the most reliable way is to use the official app. Google HomeThis method provides a more stable connection and better picture quality than standard Miracast, especially when streaming video from the internet.
First, you need to download and install the Google Home app from the store. Play MarketAfter installation, open the program and sign in to your Google account. The app will automatically scan the network and find compatible devices, such as TVs. Sony, Philips, TCL or prefixes Chromecast.
Select your TV from the list of devices. In the control menu that opens, click "Cast my screen." The system will warn you that everything that's happening on your phone's screen, including notifications, will be cast. Confirm the action, and the image will appear on the TV.
- 📱 Open the YouTube or Netflix app on your phone and tap the cast icon in the corner of the video.
- 📺 Select your TV from the list of devices; the video will start playing directly over the network.
- 🎮 Use your phone as a remote control to adjust the volume or pause the video.
The main advantage of this method is that the phone acts only as a remote control, while the TV downloads the video directly from the internet. This reduces the load on the smartphone's processor and allows you to use other apps while watching.
Xiaomi TV Assistant (Mi Remote) app for older TVs
For TVs that do not support modern wireless transmission standards, Xiaomi has developed a special application Xiaomi TV Assistant (formerly known as Mi Remote). It not only allows you to control your TV via IR but also stream multimedia content over the network.
Install the app from the app store or find it in the "Tools" folder on your smartphone. Launch the app and follow the on-screen instructions to add your TV. You may need to enter the code displayed on the TV screen to pair the devices.
Once successfully connected, go to the "Broadcast" or "Cast" section within the app. Here you can select photos, videos, or music from your phone's memory to display on the screen. Popular formats are supported, such as MP4, JPG, MP3.
Why might the broadcast be interrupted?
Frequent connection drops may be caused by Wi-Fi channel congestion from neighboring routers. Try changing the router's broadcast channel to a less congested one (for example, 1, 6, or 11 for 2.4 GHz).
It's important to understand that this solution works best within the Xiaomi ecosystem, but is also compatible with other brands that support the DLNA protocol. However, functionality may be limited to media viewing, not full screen mirroring.
☑️ Check before connection
Comparing technologies: Miracast, DLNA, and AirPlay
Users often get confused by the terms used to describe wireless data transfer. Understanding the differences between these technologies will help you choose the optimal connection method for your specific situation and equipment.
Miracast — This standard creates a direct connection between devices (P2P), bypassing the router or using it as a bridge. It's ideal for real-time screen mirroring, such as for games or presentations. However, it's susceptible to interference and can introduce latency.
DLNA It works differently: it allows you to transfer files from one device to another over a local network. The TV "sees" the phone as a media server. This is great for viewing photos and videos from the gallery, but it doesn't allow you to stream app interfaces or a browser.
AirPlay — Apple's proprietary technology, but many modern TVs (Samsung, LG, Sony) now support it. If you have an iPhone or iPad, this is the best choice. AirPlay emulators exist for Xiaomi, but they are less stable.
| Technology | Transmission type | Best use | Delay |
|---|---|---|---|
| Miracast | Screen mirroring | Games, presentations, browser | Average |
| DLNA | File streaming | Photos and videos from the gallery | Low |
| Chromecast | Stream via link | Online cinemas, YouTube | Minimum |
| AirPlay 2 | Mirroring and streaming | Apple devices | Low |
The protocol you choose depends on your goals. For gaming, a wired connection or low-latency Miracast are best, while DLNA is ideal for watching movies from your phone's hard drive.
Setting up a router for stable video transmission
The quality of your wireless streaming directly depends on your home network configuration. If the picture is choppy or the video is constantly buffering, the problem may lie in your router settings.
First of all, make sure you are using a range 5 GHzThe 2.4 GHz frequency is heavily congested in apartment buildings, leading to interference and packet loss. Switch your TV and phone to the 5 GHz network in your Wi-Fi settings.
⚠️ Note: Router interfaces from different manufacturers (Keenetic, TP-Link, ASUS) may differ. If you are unsure of your settings, consult your ISP or equipment manufacturer's documentation, as incorrect changes may disrupt your internet connection.
It also makes sense to check if the feature is enabled IGMP SnoopingIt helps the router properly distribute multicast traffic used for video streaming, preventing network "storms" when data is sent to all devices.
If the distance between devices is large, consider installing a mesh system or repeater. This will ensure uniform signal coverage throughout the entire apartment and stable speeds at any point.
Solution: Why is there no picture or sound?
Even with proper setup, technical difficulties can still arise. Most commonly, users experience a lack of sound while the image is being transmitted successfully, or a complete lack of response from the TV.
If there is no sound, check the audio settings in the app you are streaming through. Sometimes the sound stays on the phone and doesn't switch to the TV. Also, try changing the audio stream format in the developer settings (path Settings → About phone → Tap the build number 7 times → Developer options), but do it carefully.
If the devices can't see each other, try rebooting the router. Temporarily disabling mobile internet (4G/5G) on your smartphone, forcing the system to use Wi-Fi for data transfer, often helps.
- 🔄 Restart both devices: unplug the TV from the power outlet for 10 seconds.
- 🛡️ Check your antivirus or firewall on your phone; they may be blocking the local connection.
- 📶 Make sure that the guest network is not enabled on the router for any of the devices.
If nothing helps, try third-party aggregator apps such as Web Video Caster or BubbleUPnPThey often have their own drivers and search algorithms that bypass the limitations of standard system tools.
Frequently Asked Questions (FAQ)
Is it possible to stream video if there is no internet on the phone, but there is a Wi-Fi router?
Yes, you can. Internet access is not required for Miracast and DLNA to work; both devices must be connected to the same router (local network). However, internet access is still required for streaming online videos (YouTube, Netflix).
Why is there a lot of lag when streaming games?
Wireless video transmission always introduces latency due to the time it takes to encode, transmit, and decode frames. This is critical for gaming. Use an HDMI cable or lower the streaming resolution in the settings.
Does my old non-Smart TV support streaming?
An old TV doesn't support Wi-Fi on its own. You'll need an additional set-top box (TV box), such as an Android one, or an HDMI adapter with Miracast/Chromecast support that plugs into the HDMI port.
Does screen mirroring affect my phone's charging speed?
Yes, it does. Active Wi-Fi and CPU usage during video encoding significantly increases power consumption. The phone may charge more slowly or even lose battery power while in use.
