Understanding the differences between protocols Miracast And Google Cast will help avoid errors during setup and ensure a stable connection.
In this guide, we will cover all the current connection methods, including using the "Broadcast" function, working with the application Mi Remote and third-party utilities. We'll also cover common issues users encounter and offer effective solutions. No matter what type of TV you have— Samsung, LG or Smart TV based Android, you will find a working method for your situation.
Preparing equipment and network
Before starting setup, you need to ensure that both devices are in the same network conditions. This is a fundamental requirement for most wireless data protocols to work. If your smartphone is connected to a mobile data connection, 4G/5G, and the TV to the home router, direct detection of devices will not be possible.
Check that your router supports the standard. WiFi Direct, which is often used to create a direct communication channel between devices without loss of quality. In some cases, especially in office networks or public spaces, packet exchange between clients may be blocked.
- 📶 Make sure your phone and TV are connected to the same WiFi network (SSID name must match).
- 🔄 Restart your router if the connection is unstable or devices cannot see each other.
- 📱 Update your smartphone's firmware Xiaomi to the latest version via the settings menu.
- 📺 Activate the Smart TV or Screen Mirroring function in your TV menu.
⚠️ Attention: If you're using a guest WiFi network or a network with client isolation enabled, image streaming won't work. In this case, you'll need to access the main network or use access point mode if your TV supports direct connection.
It's also important to consider the router's frequency range. Modern routers often distribute two networks: 2.4 GHz And 5 GHz. For transmitting high-definition video, especially in the format 4K, it is preferable to use the 5 GHz band, as it provides greater throughput.
TV and smartphone interfaces may be updated by the manufacturer. The layout of menu items may differ slightly from that described in the instructions. Always check the latest manuals on the official website of the manufacturer of your model.

Using the built-in Cast function
The easiest and fastest way to display an image is to use the built-in system function Android, which is in the shell MIUI called "Broadcast" or "Cast". This method is based on the protocol Miracast and requires no additional software installation. It's ideal for mirroring everything that's happening on your smartphone screen.
To activate the feature, pull down the notification shade and find the "Broadcast" icon. If it's not on the first page, click the panel editing button (usually a pencil or three dots) and drag the desired widget to the active area. Once enabled, it will search for available devices within range.
Once the TV appears in the list, click on its name. A connection confirmation request may appear on the TV screen, which you'll need to accept with the remote control. After that, the image from your smartphone will appear. Xiaomi will be duplicated on the big screen.
☑️ Pre-broadcast check
It's worth noting that using this method may cause the smartphone to heat up, as the video encoding process occurs in real time. The phone's screen will also remain constantly lit, which drains the battery.
- 🎬 Open the control panel by swiping down from the top.
- 📡 Find and tap the "Broadcast" icon.
- 📺 Select your TV from the list provided.
- ✅ Confirm the connection on the TV screen if required.
⚠️ Attention: If the connection suddenly drops or the battery runs low during streaming, the process may not complete correctly. Try keeping your smartphone connected to a charger during extended viewing.
If the image quality is poor or there are delays, try moving closer to the router. Protocol Miracast sensitive to interference, and the distance to the access point plays a critical role in image stability.
Broadcast via the Google Home app
For TVs that support the technology Chromecast built-in (Chromecast built-in), the best solution would be the official app Google HomeIt's available in the store. Google Play and allows you to control not only the stream but also other smart devices in the home. This method often provides a more stable connection than standard Miracast.
After installing the app and signing in to your Google account, it will automatically scan your network and find connected devices. Select your TV from the list of devices. In the control menu that opens, click "Cast my screen."
The main advantage of this method is the ability to stream content from apps that don't have a built-in Cast button, as well as the ability to use your phone as a remote control. You can scroll through your social media feeds, and the image will be transmitted to your TV.
Why is Google Home better than standard streaming?
The Google Home app uses more advanced compression and buffering algorithms, reducing lag when gaming and navigating menus. It also works better with dual-band routers.
It is important to understand the difference between browser tab broadcasting Chrome and the entire screen. A tab allows you to display only the browser's contents, leaving your phone free for other tasks, while the "Cast Screen" feature copies the entire image.
⚠️ Attention: Some content-protected apps (such as Netflix or Disney+) may block screen recording or streaming through third-party apps due to copyright protection policies. HDCPIn such cases, use the built-in Cast button within the video service app itself.
To set high quality in the application Google Home You can change the streaming resolution. However, if your internet connection is limited, it's best to leave the settings on automatic to avoid buffering.
Specialized apps from Xiaomi and TV manufacturers
Company Xiaomi and TV manufacturers often develop their own ecosystems for deeper device integration. For example, for TVs Xiaomi TV And Mi Box the app is perfect Mi Remote, which turns your smartphone into a universal remote control. It not only allows you to control the volume but also stream media files from your phone's memory.
For TVs of other brands such as Samsung or LG, there are branded applications (SmartView, LG TV Plus), which can work in tandem with smartphones XiaomiThey often provide a more stable data transmission channel for photos and videos than general-purpose protocols.
Let's compare popular connection methods in the table below so you can choose the best option for your needs.
| Connection method | Latency | Picture quality | Difficulty of setup |
|---|---|---|---|
| Built-in "Broadcast" (Miracast) | Average | High | Low |
| Google Home (Chromecast) | Low | Very high | Average |
| Manufacturer's applications (Mi Remote) | Low | High | Average |
| Third-party applications (AllCast) | High | Average | High |
Using specialized software is justified if you plan to frequently use your phone as a remote control or media server. Otherwise, the system's built-in tools are usually sufficient.
Streaming via DLNA and local network
Protocol DLNA (Digital Living Network Alliance) allows you to stream media files (photos, videos, music) over a local network without screen mirroring. This means you play the video on your TV, and your phone acts as a storage device. Your smartphone's screen can be turned off.
To implement this method on a smartphone Xiaomi Open your gallery or video player, select a file, click "Send" or "Cast," and select your TV. The system will automatically find a compatible device on the network.
This method is ideal for viewing large files downloaded to your phone's memory, as it doesn't burden the smartphone's processor with real-time video stream encoding. The TV decodes the file itself, using its own resources.
- 📂 Open the desired video file or photo in the gallery.
- 📡 Click the Share button or the broadcast icon.
- 📺 Select a DLNA device (your TV) from the list.
- ▶️ Playback will start automatically on the big screen.
⚠️ Attention: The DLNA protocol doesn't support all video formats. If your TV displays "Format not supported," it means the TV's built-in codec can't decode that particular file. In this case, installing a third-party player on the TV itself (such as VLC) will help.
Troubleshooting and error recovery
Even with proper setup, technical issues can still occur. Often, the problem lies in the network service cache or a temporary IP address conflict. If the TV stops detecting your phone, first try forgetting the WiFi network on both devices and reconnecting.
Another common cause is an outdated version of WiFi drivers or a system component. Android System WebViewCheck for updates in the store Google Play and in the "About phone" section.
If the image is choppy or the sound is missing, try lowering the streaming quality in the app settings or switching your router to a less congested channel. In apartment buildings, the 2.4 GHz band is often overloaded by neighboring networks.
In some cases, antivirus programs or firewalls on the router may block ports required for Miracast or DLNATry temporarily disabling protection to test your hypothesis.
Frequently Asked Questions (FAQ)
Why doesn't my Xiaomi phone see my TV in the list of available devices?
Most often, the devices are on different subnets, or one of them is using guest access. Make sure both devices are connected to the same router. Also, check if AP Isolation mode is enabled on the router, which prevents devices from seeing each other.
Is it possible to connect a phone to a TV without WiFi, using only mobile internet?
Direct screencasting (Miracast) typically requires a local network. However, if your TV supports Chromecast Built-in, you can stream internet content (such as YouTube) using your phone as a remote, even if they're on different networks, as long as you're logged in to the same Google account.
Does screen mirroring affect the speed of my smartphone?
Yes, the process of encoding and transmitting a real-time video stream puts a strain on the processor and WiFi module. This can lead to the device overheating and faster battery drain. For heavy gaming, it is recommended to use a wired connection or reduce graphics settings.
How to improve the quality of a picture if it is blurry?
Blurry images are often caused by a low bitrate stream due to a weak WiFi signal. Move closer to the router, disable downloads on other devices, or switch to a 5 GHz network. Also, check if your TV is set to "Movie" or "Anti-Aliasing" mode, which can blur the dynamic image from your phone.
