Wireless image transmission via Wi-Fi Opens access to a huge library of photos, videos, and games on the big screen. This is especially convenient when you need to share vacation photos with family or watch a movie from an online cinema in high definition.
The synchronization process may seem complicated at first glance, but the ecosystem Android TV and the shell PatchWall offer a variety of built-in tools for quick setup. There are several data transfer protocols, each with its own characteristics and use cases. Understanding the differences between Miracast, DLNA And Google Cast will help you choose the optimal method for a specific task.
In this article, we'll cover all available connection methods, potential driver and router issues, and provide solutions to common errors. You'll learn how to properly configure your network to ensure a stable video stream without lag or audio desync. The key is to ensure both devices are on the same network segment.
Preparing equipment and a Wi-Fi network
Before you begin setting up, you need to make sure that your TV Xiaomi Mi TV and the smartphone are connected to the same wireless network. This is a fundamental requirement for most broadcast protocols to work. If your router supports dual-band mode, it is recommended to use the network. 5 GHz, as it provides the higher bandwidth required to transmit 4K video.
⚠️ Attention: If your router separates the 2.4 GHz and 5 GHz networks into different SSIDs (network names), make sure both devices are connected to the same network. Sometimes, a mixed connection (phone on 5 GHz, TV on 2.4 GHz) with strict router security settings can block devices from discovering each other.
It's also worth checking the software version on both devices. On the TV, you can do this by going to the settings menu and selecting Settings → About TV → System updateOn a smartphone it may differ depending on the model, but is usually located in the section About phone → Software updateOutdated Wi-Fi driver versions can cause connection instability.
To ensure maximum data transfer speed, ensure there are no large metal obstructions or microwave ovens between the router and TV that could cause interference. If the signal is weak, use a Wi-Fi repeater or connect the TV to the router via a LAN cable, leaving your smartphone in wireless mode.
Using the built-in Cast feature on Android
The most common way is to use technology Google Cast, which is built into the Android operating system. Most modern Xiaomi TVs have built-in Chromecast certification, allowing you to stream content directly from apps. You don't need to install any additional software if you use an Android smartphone.
To start casting, open the app you want to display (e.g., YouTube, Netflix, or Google Photos). Look for the rectangle icon with waves in the corner—this is the standard Cast symbol. Click it, and the system will offer a list of available devices. Select yours. Xiaomi Mi TV from the list.
If the device isn't found, check your privacy settings in the Google Home app. You may be asked to confirm the connection on your TV screen, where you may be asked for permission. Once paired, your smartphone screen will act as a remote control, and videos will play directly on the TV.
Screencasting via Miracast (Wireless Display)
If you need to display on the big screen exactly what is happening on the smartphone display (menus, games, browser), the technology is used MiracastIn Xiaomi TVs, this feature is often called "Wireless Display." It creates a direct connection between devices, eliminating the need for an active internet connection once the connection is established.
On your Xiaomi TV, you need to launch the appropriate app. Depending on the firmware version (Global or China), it may be called Wireless Display, Miracast or be in the signal sources menu InputAfter launch, a waiting for connection message will appear on the screen.
On an Android smartphone, the algorithm of actions is as follows:
- 📱 Open the quick settings panel (swipe down from the top) and find the "Cast", "Projection" or "Smart View" button.
- 🔍 Tap it and your phone will start searching for available displays within Wi-Fi range.
- ✅ Select your TV from the list and wait for the connection.
iPhone users can also use this feature if their TV supports AirPlay (often built-in on newer models) or through third-party apps. However, iOS lacks native Miracast support, so iPhone owners are better off using built-in AirPlay or clone apps.
☑️ Check before connecting Miracast
Comparison of connection methods: Table
To help you choose the right method, we've prepared a comparison table of the key characteristics of various protocols. Each method has its own advantages depending on the content you plan to watch.
| Characteristic | Google Cast | Miracast | DLNA |
|---|---|---|---|
| Transmission type | Stream from the Internet | Screen mirroring | File transfer |
| Smartphone addiction | Low (can be folded) | High (screen active) | Medium (file management) |
| Image quality | Up to 4K HDR | Depends on Wi-Fi signal | Original file |
| Battery consumption | Minimum | High | Average |
As you can see from the table, the best option for watching online cinemas is Google Cast, since it doesn't put a strain on the phone's processor. If you want to show off a game on your phone to your friends or demonstrate the app's functionality, then the only option is Miracast.
Why might the picture lag?
Lag when using Miracast is often caused by Wi-Fi congestion. If your router is simultaneously distributing internet to several devices and streaming video, the bandwidth may be insufficient. Try disabling downloads on other devices.
Using Xiaomi apps and third-party software
Xiaomi ecosystem offers its own app MI Remote (or Xiaomi TV+), which allows you to not only control your TV but also stream media content. This is especially useful for older smartphone models, which may have issues with standard protocols. The app is available on Google Play and the App Store.
After installing the app and pairing it with your TV (they must be on the same network), go to the "Media" or "Cast" section. Here, you can select photos or videos from your phone's memory and send them to the big screen. The app's interface is intuitive and supports formats that may not be supported by standard tools.
If the built-in tools don't work, you can use proven third-party solutions such as Web Video Caster or BubbleUPnPThese programs can extract video streams from websites and send them to your TV, bypassing the limitations of mobile browsers. This is a great way to watch videos from websites that don't have official TV apps.
⚠️ Attention: Third-party apps may request extensive permissions to access your local network. Use only trusted, highly rated software from official app stores to avoid personal data leaks.
Advanced users can set up a DLNA server directly on their computer, streaming content through the router to their TV using their smartphone as a remote control. This creates a flexible home entertainment network.
Troubleshooting and common errors
Despite the simplicity of the technology, users often encounter issues where the TV doesn't detect the phone or the connection constantly drops. One of the most common causes is Wi-Fi client isolation (AP Isolation) in the router settings. This feature prevents devices within the network from communicating with each other for security reasons.
To fix this, you need to go into your router settings (usually at 192.168.0.1 or 192.168.1.1) and find the setting AP Isolation or Client IsolationIt needs to be set to "Disable." After rebooting the router, the devices should be able to see each other.
Other common problems and their solutions:
- 📶 Weak signal: If your TV is far from your router, use a Wi-Fi extender or switch to a cable TV connection.
- 🔄 Different subnets: Make sure a guest network isn't enabled on your router for any of your devices. Guest networks are isolated from the main network.
- 🛡️ Antivirus: Some smartphones with aggressive antivirus software may block local connections. Try temporarily disabling the protection.
It's also worth mentioning the importance of updating the Wi-Fi module drivers in your TV. Manufacturers sometimes release patches that improve compatibility with new router encryption standards.
