Modern Xiaomi TVs running on the operating system Android TV or the proprietary PatchWall shell, offer a variety of multimedia entertainment options. One of the most popular features is the ability to stream content from a mobile device directly to a large screen wirelessly. This is convenient for viewing family photo albums, YouTube videos, or movies from a local network.
However, the setup process sometimes raises questions among users, as the transfer methods may vary depending on the smartphone model and TV firmware version. There are several basic protocols, such as Miracast, Chromecast And DLNA, each with its own unique characteristics. Understanding the differences between them will help you choose the best method for your situation.
In this article, we'll take a detailed look at all available connection options, focusing on connection stability and addressing common issues faced by Xiaomi device owners. You'll learn how to set up your network correctly and avoid lag when playing high-definition video.
Preparing your home network and equipment
Before you start transferring data, you need to make sure that all your equipment is in a single information space. Wi-Fi router It is the central hub through which video streams will pass. The quality and stability of the broadcast directly depend on the signal strength and channel load.
Make sure your smartphone and Xiaomi TV are connected to the same network. This is critical: if your phone is connected to mobile data (4G/5G) and your TV is connected to your home Wi-Fi, the devices will not be discoverable. It's also worth checking that AP client isolation isn't enabled on your router, which blocks devices from communicating within the network.
For high definition video transmission (4K HDR), it is recommended to use the range 5 GHz, which provides higher throughput compared to the 2.4 GHz standard. This frequency range has less interference from neighboring networks and household appliances.
⚠️ Note: If your router broadcasts two networks with the same name (SSID) for the 2.4 GHz and 5 GHz bands, devices may switch between them automatically. For stable operation, it's best to explicitly connect both devices to the 5 GHz network or temporarily separate the network names in the router settings.
- 📶 Check that your TV and smartphone are connected to the same router.
- 🔒 Make sure that "Guest Network" is not enabled on your router for your primary devices.
- ⚡ For 4K video, it is recommended to use 5 GHz Wi-Fi or a wired connection.
- 🔄 Restart your router if you experience constant connection drops.
Sometimes antivirus software on your computer or router security settings can block ports required for detection protocols. In such cases, temporarily disabling the strict firewall or adding devices to the trusted list can help.
Stream via Chromecast built-in
Xiaomi TVs have built-in support for this technology. Google ChromecastThis is perhaps the most convenient way to send a video, as it doesn't require installing any additional apps on your TV. It works like this: an app on your phone (such as YouTube or Netflix) uses Wi-Fi to transmit a link to the video directly to the TV, which then downloads and plays the content automatically.
To get started, open a video app on your smartphone. Find the broadcast icon, which typically looks like a rectangle with Wi-Fi waves in the corner. After tapping it, the system will prompt you to select an available device. Your device should appear in the list. Xiaomi Mi TV or Android TV.
The advantage of this method is that the phone acts only as a remote control. You can minimize an app, answer a call, or use other smartphone functions without interrupting playback on the TV. Picture quality is also maximized, as the TV buffers the video itself.
- 📱 Open the app with the video (YouTube, Kinopoisk, etc.).
- 📺 Click the "Cast" icon in the player interface.
- ✅ Select your Xiaomi TV from the list that appears.
It's important to note that not all video files stored on your phone's memory can be sent this way. Chromecast works primarily with apps that support this protocol. For transferring personal archived files, it's better to use the other methods described below.
Screen mirroring with Miracast and Wireless Display
If you need to show the entire screen content, such as a presentation, browser, or game that doesn't have built-in Chromecast support, the technology comes to the rescue. MiracastOn Xiaomi TVs, this feature is often called "Wireless Display" or "Casting."
Unlike Chromecast, the image is encoded on the fly and the video stream from the smartphone's screen is transmitted. This places a higher load on the phone's processor and Wi-Fi module, which can lead to a slight delay (latency). This isn't critical for watching movies, but it can be noticeable in fast-paced games.
Why does the image flicker when mirroring the screen?
Delays often occur due to Wi-Fi congestion or insufficient processor power on the smartphone. Try lowering the phone's resolution or moving closer to the router.
To activate the mode, press the app button on your Xiaomi TV's remote control or go to the signal sources menu. Select "Wireless Display." A waiting-for-connection message will appear on the screen. On an Android smartphone, go to the display settings and select "Cast," "Smart View," or "Proiezione schermo" (the name varies depending on the phone manufacturer).
After searching for devices, select your TV. Your smartphone screen will instantly appear on the large panel. To disconnect, simply press the "Back" button on your TV remote or disconnect from the phone menu.
- 📺 On your TV, open the Wireless Display app.
- 📲 On your phone, find "Cast" or "Smart View" in the notification shade.
- 🔗 Select a TV from the list and wait for the connection.
- ❌ To exit, press "Back" on the remote control or "Disconnect" on the phone.
⚠️ Important: When mirroring your screen, make sure your phone doesn't go into sleep mode, otherwise the broadcast will be interrupted. Increase the screen timeout in your smartphone settings while watching.
Using DLNA to play local files
Protocol DLNA (Digital Living Network Alliance) is a standard for sharing multimedia content within a home network. It's ideal if you have a high-quality movie downloaded to your phone that you want to watch on your Xiaomi TV without conversion or compression.
To implement this method, you will need a media player app on your smartphone that supports a DLNA server, or a file manager with this feature. A popular choice is VLC for Android or BubbleUPnPThe TV itself acts as a renderer (playback device).
The setup process is simple: install the player on your phone, open the desired video file, and find the "Cast" or "Play on Device" button in the menu. The app will scan the network and find your Xiaomi TV and will start streaming. The TV will decode the video itself, so the quality will be original.
The main advantage of DLNA is that there's no need to compress videos or transfer files. You simply access your phone's storage through the TV interface or via a launch command from your phone. However, rewinding and forwarding controls may be less responsive than with built-in apps.
Third-party apps for controlling Xiaomi TV
The built-in tools don't always work perfectly, especially if you need to transfer a specific file format or control your TV more flexibly. Official app Mi Remote (Mi Remote) allows you to control equipment, but specialized utilities are better suited for transferring files.
One of the most powerful tools is the application TV Cast or Web Video CasterThey allow you to send videos from websites that don't have a built-in "Cast" button, as well as stream files from cloud storage services. These apps often have a built-in browser, making it easy to find content.
Also worth mentioning is the app Xiaomi TV+ (or similar official utilities from the manufacturer) that can sync your media library. Installing such programs expands the functionality of your Smart TV, adding support for formats that the built-in player may not support.
☑️ Check before launching a heavy video
Comparison of video transmission methods
To help you navigate the connection options, we've prepared a summary table. It will help you quickly determine which method is best for a given situation, whether you're watching an online movie or sharing birthday photos.
| Method | Best suited for | Quality | Impact on battery |
|---|---|---|---|
| Chromecast | Online services (YouTube, Netflix) | High (up to 4K) | Minimum |
| Miracast | Games, browser, any applications | Depends on the signal (may be compression) | High |
| DLNA | Local video files | Original (lossless) | Average |
| HDMI (cable) | Stable picture without delays | Ideal | Charging your phone |
As you can see from the table, there's an optimal tool for each scenario. If you're watching YouTube, use Chromecast. If you need to share a photo gallery with friends, Miracast will be faster. And for a movie buff with a 100GB movie collection, DLNA is indispensable.
Solution and troubleshooting
Even with proper setup, situations may arise where the TV doesn't detect the phone or the video lags. Often, the problem lies in software glitches or IP address conflicts. First, try restarting both devices—this solves 90% of connection issues.
If your Xiaomi TV doesn't appear in the list of available devices, check to see if your phone's antivirus software is blocking your local network. Also, make sure "Allow access from mobile devices" is enabled in your TV's network settings.
If you're experiencing frequent connection drops, try statically assigning IP addresses for your TV and phone in your router settings. This will prevent the router from changing the device's address and causing connection loss. You can also try disabling IPv6 in your router settings if you're experiencing compatibility issues.
⚠️ Note: Xiaomi TV interfaces are subject to update. The location of the "Wireless Display" menu items or network settings may vary slightly depending on the MIUI TV version and region.
Sometimes clearing the cache of the Google Home or Chromecast built-in app on your TV can help. To do this, go to Settings → Apps → All Apps → Chromecast built-in → Clear CacheThis action is safe and will not delete your personal data, but it will update network discovery services.
Why doesn't my Xiaomi TV detect my phone when I try to stream?
Most often, the devices are on different subnets (for example, one is connected to a guest Wi-Fi network, the other to the main network). The issue could also be with the router settings, which prohibit packet forwarding between clients (AP Isolation). Check that both devices are connected to the same 2.4 or 5 GHz network.
Is it possible to stream video from iPhone (iOS) to Xiaomi TV?
Yes, this is possible. Since Xiaomi uses Android TV, older models may not have direct AirPlay support. However, many modern Xiaomi models support AirPlay 2. If this feature isn't available, install the "AirScreen" app from the Google Play Store on your TV, which emulates Apple's signal reception.
The video is lagging when mirroring the screen. What should I do?
Reduce the output resolution on your phone or close background apps. Make sure your router isn't overloaded. For viewing large files, it's better to use DLNA or built-in apps (YouTube, Kinopoisk) rather than full screen mirroring (Miracast), as it's more resource-intensive.
How to improve sound quality when transmitting video?
If the sound coming from your TV seems quiet or hoarse, try changing the equalizer mode to "Movie" or "Standard" in the TV settings (under "Sound"). You can also connect external speakers via Bluetooth or optical output if the quality of the built-in speakers isn't satisfactory.
Does the operator charge for transmitting video to the TV?
No, data transfer within your home network (between your phone, TV, and router) doesn't consume mobile data and isn't charged by your carrier. However, if you watch online videos, your data is charged to your home internet connection at your provider's rate.
