In the digital age, smartphone and laptop screens often seem too small to comfortably watch movies or present work projects. Xiaomi and Mi TV owners have the unique ability to turn their TV into a multimedia center simply by transferring an image from a computer. This action does not require complex engineering knowledge, but knowing the nuances of data protocols will help to avoid delays and desynchronization of sound.
There are several main ways to do this: using built-in Windows, using third-party applications, or physically connecting via cable. The choice of method depends on how stable your Wi-Fi router is, which version of the operating system is installed on TV, and whether you want maximum image quality without compression. In some situations, wireless technology can fail due to air congestion.
In this article, we will take a detailed look at each available algorithm of actions, paying special attention to setting up network parameters and eliminating typical errors, you will learn how to activate the monitor mode on the TV and why it is sometimes necessary to manually prescribe the device. IP-Device addresses. For wireless video transmission to 4K It is critical that the laptop and TV operate in the 5 GHz band, as the 2.4 GHz frequency will not provide the necessary bandwidth.
Device preparation and network infrastructure
Before you start setting up your broadcast, you need to make sure that both devices are in the same network conditions. This is a basic requirement for Miracast and DLNA. If your router supports dual-band mode, it is highly recommended to switch your laptop and TV to a 5 GHz network, since it is less susceptible to interference from microwave ovens and neighboring networks.
Make sure that the current firmware version is installed on the Xiaomi Mi TV. Manufacturers regularly release updates that improve the stability of the Wi-Fi module and add support for new codecs. Go to the settings menu and find the system update to eliminate software errors.
- 📶 Make sure your laptop and TV are connected to the same Wi-Fi network (SSID).
- 🔄 Update your wireless adapter drivers to the latest version.
- 📺 Check if device detection is enabled in the TV network settings.
⚠️ WARNING: If you use a guest Wi-Fi network or a corporate Internet with customer isolation, devices will not be able to “see” each other, and broadcasting will not be possible.
Sometimes, an embedded Windows firewall or third-party antivirus can block incoming connections from the TV, perceiving them as a security threat, in which case you will need to create an exception for the media content service.
Use of the built-in Connection feature in Windows
The easiest way to do this is to use the native function of Windows 10 and Windows 11. The Wi-Fi Direct technology behind this method allows you to stream video directly, bypassing the router if devices support this option, or via a local network.
To start the process, on the Xiaomi TV remote, find the signal source button (Input or the arrow square icon). In the list of available connections, select a item that may be called Wireless Display, Miracast or Screen Mirroring.
☑️ Checking before connection
Now, to the computer, press the Win + K keyboard, and the Connection sidebar will come out on the right, and the system will start looking for available devices, and as soon as your Mi TV name appears on the list, click on it.
After successful pairing, the laptop screen will be duplicated on the TV. You can change the projector mode by pressing Win + P. The modes available are: "Duplicate" (screen copy), "Expand" (second desktop) and "Only second screen" (laptop screen goes out).
- 🖥️ Duplicate: the image from the laptop is copied to TV, convenient for video.
- 📐 Expand: TV becomes second monitor, you can drag and drop windows.
- 📺 Second screen only: laptop turns off its display, saving energy.
What if Windows can’t see the TV?
Broadcasting via Google Chrome and Chromecast
Many Xiaomi TVs have built-in support for Google Cast technology or are software-compatible, which allows you to stream the contents of the Google Chrome browser tab or the entire desktop screen with high quality.
Open the Google Chrome browser on your laptop. In the upper right corner, click three vertical dots to open the menu. Find the "Cast" option. If you have an older version of the browser, this item may be in the "Save and Share" submenu.
In the window that opens, you'll see a list of available devices. Click on your TV name. It's important to note that by default, the browser may only offer to broadcast a tab. To transfer the entire interface, click on Sources and select Translate Desktop.
| Parameter | Description | Impact on broadcasting |
|---|---|---|
| Permission | Depends on the monitor settings | High resolution requires powerful Wi-Fi |
| Frequency of personnel | Usually 30 or 60 FPS. | Affects the smoothness of cursor movement |
| Audio. | Systemic sound | Sound goes through the TV speakers |
| Delay. | 1-3 seconds | Not suitable for dynamic games |
This method is particularly useful if you need to show a presentation or a web page, but for viewing heavy video files from a hard drive, it may be less effective because of real-time stream encoding.
💡
To reduce latency when streaming through Chrome, close the remaining tabs consuming traffic and stop downloading files in the background.
Application of third-party applications: AirPin and analogues
If the built-in tools are unstable or your Xiaomi TV runs on a stripped-down version of Android TV, specialized apps come to the rescue. One of the most popular solutions is AirPin(PRO) or its free counterparts, which emulate the reception of the AirPlay and Miracast signal.
Install the app from the Google Play Store directly on your TV. Once launched, it will create an access point or be visible on the network. On your laptop, you may need to install client software or use a web interface that will be listed on the TV screen.
The advantage of these programs is that they have flexibility in settings, so you can adjust buffering, which helps smooth out the jerks of images when the Internet is unstable, and there's often a feature that's available to transmit audio separately from video, which is useful when using external speakers.
- 📲 AirPin: supports iOS and Android devices, there is a version for PC.
- 📺 LetsView: Free App with Good Image Quality.
- 💻 ApowerMirror: a powerful tool for managing TV from PC.
⚠️ Warning: Free versions of translation apps often contain banner ads that can cover a portion of an image or interrupt the video stream every 15 minutes.
Physical connection via HDMI cable
When wireless technology is not up to the task, or you need to transfer images in 4K HDR without loss of quality and delay, the best solution is the classic cable. HDMI (High-Definition Multimedia Interface) provides uncompressed video and multichannel audio.
You'll need a standard HDMI-HDMI cable if you have a port on your laptop. Modern ultrabooks often use USB-C or Mini DisplayPort connectors, which require an active adapter or docking station that supports video output.
Connect the cable to your laptop and TV. Switch the TV signal source to the appropriate port (e.g. HDMI 1 or HDMI 2). The system automatically detects a new device. If the image does not appear, right-click on your desktop, select Screen Settings, and click Detect.
To adjust the image quality, go to "Additional Display Parameters" where you can set the correct refresh rate (60 Hz recommended for TV) and color depth. Using the cable eliminates interference problems from neighboring routers.
💡
Cable connection is the only way to guarantee zero input lag, which is critical for gaming and graphics.
Elimination and optimization of quality
Even with the right setup, users can encounter artifacts: scattering pictures into squares, dissynchronizing lips and sound, or intermittent connection breaks, most often due to congestion of the Wi-Fi channel or a lack of processing power on the TV to decode the flow.
Try lowering the resolution of the broadcast image in the settings of the Windows projector. Instead of 1920×1080, try 1280×720. This will significantly reduce the load on the network.
If the sound is behind the video, check the audio output settings. In some cases, switching the audio format in the speaker (TV) properties from Dolby Digital to 16 bit, 44100 Hz or 48,000 Hz helps, which reduces the load on the TV processor when decoding the audio stream.
