Modern multimedia systems make it possible to create full-fledged home theaters using affordable equipment, and one of the most popular requests is how to connect a computer to a Xiaomi TV via Wi-Fi. A wireless connection eliminates the need to run long HDMI cables across the room, preserving the aesthetics of the interior and allowing the laptop freedom of movement. Unlike wired methods, wireless data transmission requires proper network configuration and an understanding of the principles of broadcast protocols.
Xiaomi TVs run on the Android TV operating system, which significantly simplifies PC integration with support for numerous native features and third-party apps. You don't need to be a networking expert to set up screen mirroring or file transfer; simply follow a logical sequence of steps. In this article, we'll cover all available options in detail, from built-in Windows tools to specialized utilities that ensure a stable, lag-free picture.
Before you begin setup, it's crucial to ensure both devices are on the same local network. This means both your computer and TV must be connected to the same router, either via Wi-Fi or a LAN cable. If one of the devices is connected to a guest Wi-Fi network or using mobile data via a hotspot, direct detection and video streaming will not be possible. Checking this condition is the first and mandatory step, ignoring which leads to 90% of all errors when trying to connect.
Preparing equipment and checking network settings
To begin the integration process, carefully check your home network configuration. Make sure your router's AP Isolation feature isn't enabled. This feature is often enabled by default on public networks, but can be accidentally enabled at home. This feature prevents devices connected to the Wi-Fi network from seeing each other, making streaming or file transfers over the local network impossible.
It's also worth paying attention to the frequency range of your wireless network. For high-quality video content in high resolution, such as 4K or Full HD, it's preferable to use the frequency range 5 GHzIt provides higher throughput and is less susceptible to interference from neighboring routers and household appliances operating on the 2.4 GHz frequency. If your router is dual-band, ensure both devices are connected to the 5 GHz network for maximum stability.
On your Xiaomi TV, you need to ensure the relevant discovery services are enabled. Most Android TV models have these enabled by default, but major firmware updates can reset these settings. Check that your TV has internet access, as some protocols, such as Chromecast, require license verification or component downloads upon first launch.
⚠️ Warning: Some antivirus programs and firewalls on your computer may block incoming connections from your local network. If your devices can't see each other, temporarily disable protection or add your home network to your trusted list.
Using the built-in Projection feature in Windows
The easiest and fastest way, which doesn't require installing any additional software, is to use Miracast technology, which is built into Windows 10 and 11. Xiaomi TVs support this protocol at the system level, allowing you to mirror your PC screen almost instantly. To get started, press the app menu button on your TV remote control and find the shortcut. Wireless monitor or Cast.
After launching the app, a waiting-for-connection message will appear on the TV screen. At this point, press a key combination on your computer. Win + KThe system will begin searching for available devices within range. In the list that appears, you'll see the name of your Xiaomi TV, which usually matches the device model or the name you specified.
After selecting a device, a connection confirmation message may appear on the TV screen. Use the remote control to confirm the connection. The desktop image will appear on the large screen, and you can choose the operating mode: mirroring screens, extending the desktop, or displaying only on the second screen. Image quality and latency depend directly on the power of your Wi-Fi router.
If you plan to use your TV as a second monitor for working with documents or spreadsheets, extend mode allows you to drag windows between screens, maximizing the usable space. For watching videos or presentations, it's best to select mirroring mode to ensure the image on both your PC and TV is identical.
☑️ Check before connection
Broadcasting via Google Chrome browser (Chromecast)
An alternative and often more stable method is to use Chromecast technology, built into the Google Chrome browser. Since Android TV natively supports this technology, this method often works faster and with less lag than standard Windows casting. First, make sure you have Google Chrome installed on your computer and are logged in to your Google account.
Open your browser and click the three dots in the upper right corner to open the menu. Select Broadcast... (Cast). The browser will scan the network and find your Xiaomi TV. You can choose to cast a specific tab, the entire desktop, or a single file.
An important feature of this method is the ability to stream content from tabs that don't natively support TV output. For example, you can open an online movie theater website that blocks built-in Chromecast and simply stream the entire browser tab. This is a universal solution for any web resource.
When selecting "Cast Desktop" mode, audio will also be transmitted to the TV, but audio and video may be out of sync. In this case, we recommend selecting the "Optimize for Video Content" option in your browser's casting settings, if available, or switching to full screen to minimize buffering.
Third-party programs for advanced broadcasting
When standard tools don't provide the required quality or functionality, specialized applications come to the rescue. One of the most popular solutions is the program LetsView or AirServer, which can be installed on both your computer and TV (via the Google Play Store on Android TV). They offer more flexible quality settings and often have lower latency.
Another powerful tool is the app VLC Media PlayerIt allows you to not only broadcast your screen, but also send specific video files from your computer to your TV via the DLNA network. To do this, select the menu in VLC Playback → Renderer and select your TV. The file will start playing on the big screen, controlled from your computer.
For gamers or users who value minimal latency, there are programs like Steam LinkAlthough they were originally designed for gaming, their image transfer mechanism also handles regular video content perfectly, ensuring a smooth picture even with intense on-screen motion. Installing the app on a TV or PC takes just a couple of minutes.
Using third-party software is especially important if you want to stream audio separately from video or set up complex display schemes. However, it's important to remember that free versions of such programs may have session time or image quality limitations.
Why might third-party programs work better?
Third-party applications often use their own compression codecs, which are more efficient than standard Windows protocols in unstable Wi-Fi conditions, sacrificing a minimum amount of detail for the sake of smooth images.
Comparison of connection methods and their characteristics
To help you choose the best option, we've prepared a comparison table of the main connection methods. Each has its own strengths and weaknesses, depending on your specific needs: whether it's watching a movie, giving a presentation, or working with text.
| Method | Latency | Image quality | Difficulty of setup |
|---|---|---|---|
| Miracast (Win+K) | Average | High (up to 1080p/4K) | Low |
| Google Chrome Cast | Low | High (depending on the tab) | Low |
| VLC (DLNA) | Missing (file) | Maximum (without compression) | Average |
| Third-party software | Varies | Customizable | High |
As the table shows, VLC is best for simply viewing photos or videos, as it doesn't compress the stream on the fly, but streams the finished file. Chrome Cast is ideal for showing presentations or working in the browser. And for quick, effortless desktop mirroring, the built-in Miracast is ideal.
It's worth keeping in mind that the quality of a wireless connection will always be inferior to wired HDMI, especially during fast-paced scenes. If you plan to watch heavy 4K movies with a high bitrate, the wireless connection may not be able to handle the data flow, and the image will appear blocky.
Troubleshooting connection issues and errors
Despite the ease of setup, users often encounter issues with the TV not appearing in the list of available devices. Most often, this is due to the wireless adapter drivers on the computer. Make sure the Wi-Fi module driver is updated to the latest version, as older versions may not correctly support discovery protocols.
Another common issue is audio and video desync. This can be resolved by reducing network load: disable downloads on other devices, move closer to the router, or switch to the 5 GHz band. Also, try lowering the display resolution in Windows display settings before connecting.
If the connection drops after a certain amount of time, check your Wi-Fi adapter's power-saving settings. In Windows Device Manager, find your adapter, go to Properties, and under the "Power Management" tab, uncheck the box next to Allow the device to turn off to save power.
⚠️ Note: The Android TV interface and system app names may vary depending on the firmware version and regional version of your Xiaomi TV. If you don't find the feature you're looking for, use the menu search or refer to the official documentation.
Frequently Asked Questions (FAQ)
Is it possible to connect a computer to a Xiaomi TV without a router?
Yes, this is possible by creating a direct Wi-Fi connection. Xiaomi TVs often have an "Access Point" or "Direct" feature in their network settings. You can connect your computer directly to the TV's Wi-Fi signal, but in this case, the PC won't have internet access unless it uses a second adapter (such as an Ethernet or 4G modem) to connect to the network.
Why is the image resolution low when connected via Wi-Fi?
Most likely, your Wi-Fi signal is too weak or overloaded. Wireless broadcast protocols automatically reduce image quality to avoid stuttering and buffering. Try moving the router closer to your TV and computer or switching to a less congested channel in the router settings.
Does Xiaomi support audio transmission to external speakers when broadcasting?
When using Miracast, audio is typically sent to the TV. If you want audio to go to your computer or a connected Bluetooth headset, you'll need to change the audio output device in Windows after connecting. Click the speaker icon in the system tray and select the desired output device.
Does connecting other devices to Wi-Fi affect picture quality?
It certainly does. Wireless channels have limited bandwidth. If someone on the network is actively downloading files, playing online games, or watching videos on another device, there may not be enough bandwidth to transmit video from the PC to the TV, resulting in a drop in quality.
Is internet required for Miracast to work?
No, an internet connection is not required. Miracast technology works directly between devices via Wi-Fi Direct. The only requirement is that the Wi-Fi adapters are turned on. However, an internet connection may be required for initial setup or downloading drivers.
