Modern users rarely limit themselves to watching videos exclusively from built-in apps. They often need to display a presentation from their computer on the big screen, play a movie from the browser, or show off photos from their archive. Xiaomi are in an advantageous position because the operating system Android TV offers a wide range of tools for wireless synchronization of devices.
The main advantage of this approach is the elimination of unnecessary wires, which often get tangled and spoil the interior. For successful signal transmission, you'll need a stable local network and proper configuration of both devices. In this article, we'll cover all current connection methods in detail, from built-in Windows features to third-party software.
It's worth noting that image quality directly depends on your router's bandwidth. If your router operates at 2.4 GHz, lag or reduced resolution may occur during streaming. Therefore, before beginning setup, make sure both your laptop and TV are connected to the same Wi-Fi network, preferably in the 5 GHz band.
Equipment preparation and basic requirements
Before you begin any active work, you need to make sure your devices are compatible and ready. Most modern models Xiaomi Mi TV And Redmi TV They are equipped with a built-in Wi-Fi module and support wireless multimedia standards. However, older routers may not be able to handle heavy 4K video streams.
The key factor is the operating system version on the laptop. For native operation without installing additional software, Windows 10 and Windows 11 are best, as the technology Miracast Built-in by default. MacOS or Linux users will have to resort to alternative solutions, which we'll also discuss below.
⚠️ Important: Make sure the "AP Isolation" feature is not enabled on your router. If this option is enabled, devices on the same network will not be able to see each other, and connection will be impossible.
It's also worth checking your TV's firmware updates. Manufacturers regularly release patches that improve the stability of wireless modules. Go to the settings menu and find About device → System updateto eliminate software errors.
☑️ Check before connection
Method 1: Using Miracast Technology (Windows)
The easiest and fastest way to broadcast an image is to use the built-in "Projection" function. This technology, known as Miracast, allows you to transmit video and audio directly from your computer to your TV screen without using a router (Wi-Fi Direct mode) or via a local network.
To get started with the remote control Xiaomi TV Find the "Wireless Display" app. In some firmware versions, it may be called "Broadcast" or be in the list of signal sources. SourceAfter launching the application, a waiting for connection message will appear on the screen.
On a Windows laptop, follow these steps:
- 🖥️ Press the key combination
Win + Kto open the connection panel. - 📡 Find your TV's name in the list of available devices Xiaomi.
- ✅ Click on the device name and wait for confirmation on the TV screen.
- ⚙️ If necessary, select the "Repeat" or "Expand" mode from the menu
Projection.
If the system reports that "the PC does not support Miracast," the problem may lie with the graphics card or Wi-Fi adapter drivers. In this case, try updating the drivers through the Device Manager or the laptop manufacturer's website. Also, make sure your antivirus software isn't blocking device detection on the local network.
What to do if the mouse cursor does not move?
When using the "Repeat" mode, the cursor may not be visible or may experience a delay. Switch to "Extend" using the Win+P menu to use the TV as a second monitor with a separate desktop.
Method 2: Cast via Google Chrome (Chromecast)
Because televisions Xiaomi are based on Android and have built-in support for the technology. Chromecast built-inThis allows you to stream Google Chrome browser content or individual tabs directly to a larger screen. This method is especially convenient for viewing web pages or videos from sites that don't have their own apps.
To implement this method, you will need Google Chrome installed on your laptop. Open the browser, click the three dots in the upper right corner, and select Broadcast... (Cast). The system will automatically begin searching for available devices on the network.
In the window that opens, you will see several options:
- 🌐 Cast Tab: Casts only the contents of one open tab.
- 🖥️ Cast Screen: duplicates your entire laptop desktop with sound.
- 📁 Stream File: Allows you to select a specific video file from your hard drive.
It's important to understand the difference in load. When streaming a tab, the laptop's processor handles encoding, which can cause the device to heat up. When streaming a file via Chromecast, the TV can handle some of the processing, reducing the load on the computer.
Method 3: Third-party apps and DLNA
When standard methods are unstable or require advanced functionality, third-party solutions come to the rescue. Protocol DLNA Allows you to transfer media files (videos, photos, music) over the network without screen mirroring. This is ideal for watching downloaded movies in high quality.
To set up a DLNA server on your computer, you can use the built-in "Media Streaming" function in Windows or install specialized software, for example, Universal Media Server or PlexOn TV Xiaomi Simply open the "Media Player" or "Video Player" application, where your computer will appear in the list of sources.
Comparison of popular connection methods:
| Method | Delay | Quality | Complexity |
|---|---|---|---|
| Miracast | Low | High | Low |
| Chromecast | Average | High | Low |
| DLNA | Absent | Maximum | Average |
There are also apps for remote control and streaming such as TeamViewer or AnyDesk, which can also be installed on a TV Box if the TV supports APK installation. However, for simple video viewing, they are overkill and can introduce noticeable lag.
⚠️ Please note: The Android TV interface may differ on different Xiaomi models (Mi TV Stick, Mi Box, built-in Android). App layout and menu item names may vary depending on the firmware version and region.
Setting resolution and refresh rate
After a successful connection, it's important to ensure the image is displayed at the correct resolution. The system often defaults to a low-quality, safe mode to ensure a stable connection. To comfortably view 4K content, you'll need to manually adjust the appropriate settings.
Go to the display settings on your laptop (right-click on the desktop → Screen parameters). Select the TV on the second monitor and scroll down to "Display Resolution". It is recommended to select the value 3840 × 2160 for 4K TVs or 1920 × 1080 for Full HD models.
Pay special attention to the refresh rate. For movies, the standard is 60 Hz, but if you plan to play games or work with text, try setting it 50 Hz or 24 Hz, if your TV supports Cinema mode. This can eliminate micro-tearing in the image.
Troubleshooting connection issues
Even with proper setup, technical issues may still occur. The most common issue is that the TV isn't listed as an available device. In this case, try rebooting the router, as the network table cache may be full. Disabling the Windows Firewall briefly to test the issue may also help.
If the image flickers or the sound breaks up, this indicates insufficient bandwidth. Try disconnecting other devices from the Wi-Fi or switching your laptop to an Ethernet cable while leaving the TV connected to the wireless network. This will reduce congestion and stabilize the stream.
List of actions to take if there is no signal:
- 🔄 Restart both devices (laptop and TV).
- 📶 Check if the router is set to "Guest Network" mode for one of the devices.
- 🛡️ Add an exception for the broadcast service in your antivirus settings.
- ⏳ Make sure the system time on your laptop and TV is synchronized.
In rare cases, resetting Windows network settings can help. Open a command prompt as administrator and enter the command netsh winsock reset, then restart your computer. This will clear the network stack of any possible errors.
Why can't my Xiaomi TV detect my laptop via Wi-Fi?
Most often, the problem is that the devices are connected to different networks (for example, one to 2.4 GHz, the other to 5 GHz, and the router isolates them) or client isolation is enabled. Also, check whether your antivirus software is blocking network detection.
Is it possible to connect a MacBook to Xiaomi TV?
Not all Xiaomi models support AirPlay directly. If this feature isn't built-in, install an AirPlay emulator app (such as AirScreen) from the Google Play Store on your TV, and your Mac will see the TV as a native device.
How to improve picture quality during broadcasting?
Use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX). Connect your laptop to the router via cable and leave your TV connected via Wi-Fi, or vice versa, to reduce the load on your wireless network.
Is there any audio delay when connecting via Miracast?
A small amount of latency is inherent to wireless transmission technology. While it's unnoticeable for movies, it can be critical for games. In your TV's audio settings, you can sometimes find a "Game" mode or disable audio post-processing to reduce latency.
