Modern Xiaomi smartphones boast powerful screens and performance that often surpasses the capabilities of many laptops. It's natural to want to use a large computer monitor for watching videos, presentations, or simply for more convenient control of your device. Fortunately, the Android ecosystem and MIUI make this easy using a Wi-Fi connection. This eliminates the need to find cables and configure complex wired connections, making the process as convenient and fast as possible.
However, despite the apparent simplicity, users often encounter various nuances when trying to sync devices. This may be due to router settings, operating system versions, or network protocol specifics. In this article, we'll cover all available methods in detail, from built-in functions. Mi Drop to specialized software. You'll learn not only how to display images but also how to optimize your connection to minimize latency.
Before moving on to specific instructions, you need to make sure your equipment is ready for use. Make sure both devices are on the same local network and have a stable signal. It's also worth checking that the discovery feature is enabled in your router's security settings, as some providers isolate clients from each other by default. Proper preparation is the key to a successful and quick setup. broadcasts.
Preparing the network and devices for synchronization
The foundation of any wireless data transmission is a stable network. For high-quality images without jerks or compression artifacts, it is recommended to use the standard WiFi 5 GHz, if your devices support it. The 2.4 GHz frequency can be congested by neighboring routers and household appliances, resulting in a drop in bitrate and increased ping. Check that your router is broadcasting on both frequencies or manually switch your phone to the faster network.
The second important step is updating your software. Make sure that your Xiaomi The latest available version of MIUI or HyperOS is installed. Older firmware versions may contain bugs that block the Miracast or DLNA protocol. Similarly, the computer should have the latest drivers for the network adapter and graphics card, as they are responsible for decoding the video stream in real time.
⚠️ Note: If you're using a guest WiFi network or a corporate router with AP Isolation, devices won't see each other. In this case, broadcasting is impossible until the router's administrator changes the settings.
It's also worth paying attention to power saving settings. MIUI's aggressive algorithms can disable WiFi or limit background app activity, leading to connection drops at the most inopportune moment. We recommend temporarily disabling power saving mode or adding necessary apps to the exception list to ensure smooth operation.
☑️ Check before connection
Using the built-in Cast function
The simplest and most native method, requiring no additional software, is to use Miracast technology, which is built into Android. On Xiaomi smartphones, this feature is often called "Cast" or "Wireless Display." It allows you to mirror your phone's screen to any compatible receiver, including computers running Windows 10 and 11 that have built-in wireless display support.
To activate on a PC, open the Settings app, go to the System section, and find "Projecting to this PC." If the feature isn't installed, the system will prompt you to add an additional component. After activation, set the launch permission so your phone can detect the computer without asking for confirmation each time. This will significantly speed up the connection process.
On the Xiaomi phone side, the sequence of actions is as follows:
- 📱 Open the notification shade and find the "Broadcast" icon.
- 📡 Enable the search for available devices in the menu that appears.
- 💻 Select your computer's name from the list of found gadgets.
- ✅ Confirm the connection on the monitor screen if required.
The image quality in this mode depends on the router's power. Standard resolution is usually 1080p at 30-60 frames per secondThis is more than sufficient for viewing photos or presentations, but input lag may be noticeable for fast-paced games. Use this method for static content or interface demonstrations.
What to do if the computer doesn’t see the phone?
Make sure the "SSDP Discovery Service" and "UPnP Service" are enabled on your PC. Also, check the network type in Windows—it should be "Private" and not "Public," otherwise the system will block device discovery.
Mi Share app and file transfer
If your goal is not real-time screen mirroring, but fast transfer of large files, videos or photo series, then the built-in application Mi Share (formerly Mi Drop) is the perfect solution. It works similarly to Apple's AirDrop, using WiFi Direct to create a direct connection between devices, bypassing the router, ensuring high data transfer speeds.
To use it on a computer, you need to install the official Mi Share app from the Xiaomi website or use the web version if it's supported by your MIUI version. After launching the app on your PC and activating the feature on your phone, the devices will automatically find each other. Transfer speeds can reach tens of megabytes per second, making them several times faster than Bluetooth.
The main advantages of using Mi Share:
- 🚀 High transfer speed without quality compression.
- 🔋 Low power consumption compared to video streaming.
- 🔄 Ability to transfer files of any format and size.
- 📂 Conveniently manage your PC file system directly from your phone.
It's important to note that Mi Share isn't designed for streaming games or live video. It's designed for file sharing. If you try to play a video file through this channel, it will first download to your PC before you can open it. For multimedia, the other methods described below are better suited.
Third-party screen streaming programs
Built-in Windows and Xiaomi tools are good, but often limited in functionality. Third-party apps offer advanced features: screen recording, keyboard control, bitrate adjustments, and resolutions higher than 1080p. One of the leaders in this niche is ApowerMirror or AirDroid, which work stably and have a clear interface.
To get started, you need to install the client on your computer and the app on your smartphone. Once launched, both devices must be on the same WiFi network. The phone app will prompt you to scan the QR code displayed on the monitor or enter a PIN to pair. A copy of the phone's display will then appear on the PC screen.
Comparison of popular streaming solutions:
| Program | Latency | Quality | PC control |
|---|---|---|---|
| Built-in Cast | Average | HD | No |
| ApowerMirror | Low | Full HD / 4K | Yes (Mouse/Keyboard) |
| AirDroid Cast | Low | HD | Partially |
| Scrcpy (ADB) | Minimum | No restrictions | Yes (Full) |
Using third-party software is especially important for gamers or streamers who value minimal latency. Many programs allow you to customize encoding parameters, choosing between image quality and response time. This provides flexibility depending on your needs, whether it's viewing high-resolution photos or playing a mobile game.
Advanced Method: Scrcpy via ADB
For users who are not afraid of the command line and want to get maximum performance, the best choice would be the utility ScrcpyThis is an open-source project that streams your Android screen to a PC via the ADB (Android Debug Bridge) protocol. It doesn't require any apps to be installed on your phone, operates with minimal latency (35-70 ms), and offers high frame rates, while placing virtually no load on your smartphone's processor.
To run Scrcpy, you need to enable "USB debugging" in the "Developer options" menu on your phone. Although the name implies USB, Scrcpy also works perfectly over WiFi (ADB over WiFi). First, connect your phone with a cable for the initial setup, and then switch to a wireless connection. The connection command looks like this: adb connect IP_ADDRESS_PHONE:5555.
adb tcpip 5555adb connect 192.168.1.XX:5555
scrcpy --bit-rate 8M --max-fps 60
Once the connection is successful, the cable can be disconnected. Launch the program with the specified parameters (--bit-rate And --max-fps) will provide a smooth, high-quality picture. This method is ideal for testing apps, screen sharing, or gaming, as it provides the best response of all wireless methods.
⚠️ Note: Command line interfaces and ADB parameters may change with Android updates. Always check the official Scrcpy project documentation on GitHub for the latest commands to avoid connection errors.
Problem solving and optimization
Even with proper setup, problems may still occur: audio and video desync, intermittent freezes, or complete connection loss. Most often, the cause is a congested WiFi channel. If there are many nearby networks, try changing the channel in your router settings to a less congested one (for example, 1, 6, or 11 for 2.4 GHz, or any free channel for 5 GHz).
Another common issue is the Windows Firewall. It can block incoming connections for streaming apps. Check the list of allowed apps in your security settings and make sure your antivirus or built-in security software isn't blocking ports used for streaming (usually ports in the range 10000-20000 or application-specific).
Basic steps to diagnose problems:
- 🔄 Restart the router and both devices (phone and PC).
- 📉 Reduce the broadcast bitrate in the app settings.
- 🚫 Disable the VPN on your phone and computer while connected.
- 🔌 Move closer to the router to strengthen the signal.
If all else fails, try resetting your phone's network settings. This will delete saved WiFi passwords, but it often resolves issues with Android network drivers. Also, make sure your computer isn't running any heavy tasks consuming all of your internet bandwidth, as WiFi bandwidth is shared among all active devices.
Frequently Asked Questions (FAQ)
Is it possible to stream audio from a phone to PC speakers?
Yes, most modern methods (ApowerMirror, built-in Windows 11 broadcasting, Scrcpy) also transmit audio. In the broadcasting app's settings, make sure the audio output device is selected as "System Speakers" or a similar device. On older versions of Android (below 10), wireless audio transmission may be limited by the system.
Why does my phone get so hot when broadcasting?
The process of encoding a video stream in real time and the constant operation of the WiFi module at high frequencies put a significant load on the processor and radio module. This is normal. For longer sessions, it is recommended to remove the case for better heat dissipation or connect the phone to a charger if the battery drains quickly.
Does the broadcast work without the Internet, only through a router?
Yes, local streaming (Miracast, DLNA, Scrcpy) doesn't require internet access. Both devices need to be connected to the same router, even if the router doesn't have access to the external network (WAN). Data is transmitted within the local area network (LAN).
How to reduce lag when playing via streaming?
Use the Scrcpy method with a 5 GHz WiFi connection. Also, prioritize performance over image quality in the streaming settings. Close all background apps on your phone to free up CPU resources for video encoding.
