Modern multimedia systems make it easy to stream content from your computer to the big screen, eliminating unnecessary cables. Wireless connectivity has become the standard for high-resolution video, photo and music. Xiaomi and Mi TV owners have access to built-in broadcast protocols that do not require the purchase of additional adapters.
In this article, we’ll look at all the current ways to connect, from built-in Windows features to third-party applications. You’ll learn how to configure Wi-Fi Direct to minimize signal delay, and what to do if devices can’t see each other on the network. Image quality and connection stability are directly dependent on the correct router configuration.
Before you start setting up, make sure your laptop and TV are on the same LAN. This is a fundamental requirement for most streaming technologies to work. If a router is distributing a network at 2.4 and 5 GHz, it is better to use a faster range to transmit heavy video streaming.
Preparation of equipment and Wi-Fi network
The first step is to check the network infrastructure. To transfer images to 4K or Full HD comfortably without compression artifacts, you need a stable communication channel. Make sure the router supports 802.11ac or newer, as older protocols may not pull the high bitrate of the video stream.
It's also worth checking out software updates on the TV itself. Manufacturers often release patches that improve Wi-Fi and compatibility with different laptop operating systems. Go to the settings menu and find the system update.
⚠️ Note: If your router is set to isolate client devices (AP Isolation, laptop and TV won’t be able to detect each other even on the same network.
In some cases, manual input helps. IP-Addresses or router channel changes to less busy, interference from neighboring networks can significantly reduce data transfer speeds, causing images to hang over.
Using Miracast Technology in Windows
Windows 10 and 11 have built-in support for Miracast technology, which allows you to duplicate the screen without installing additional software. Xiaomi TVs usually support this protocol out of the box or through the built-in wireless display application.
To start the broadcast, press the Win + K keyboard on your laptop. On the right side of the screen, the Connect panel will appear, where your TV should be displayed. If you find a device, just click on it to start pairing.
If the automatic search didn't work, you can use the screen settings. Go to Settings → System → Display and scroll down to the "Connect to Wireless Display" button. The system will begin a forced search for available signal receivers.
☑️ Checking before connecting Miracast
Once you have a successful connection, you can choose to work either in duplicate screen or desktop extension mode, and in expansion mode, the TV will become a second monitor, which is convenient for watching video in the browser window while you are working on other programs.
Broadcasting via Google Chrome and Chromecast
Most Mi TVs have built-in Chromecast technology, which allows you to stream the contents of the Google Chrome tab or the entire screen directly to the TV, a method that often works more stable than Miracast, especially for online video.
Open the Chrome browser on your laptop and click on the three dots in the top right corner of the menu. Select "Cast." In the window that opens, select the source: tab, entire screen or file.
In the list of available devices, find your Xiaomi TV. If you stream a tab, the sound will be transmitted along with the video. When broadcasting the whole screen, you may need to set up the sound transmission in the Windows mixer separately.
Why does video slow down when broadcasting?
The advantage of this method is that it's cross-platform, and you can stream content not only from Windows, but also from macOS or Linux, where it's installed, and the key is to have a good Wi-Fi signal in the receiving area.
Applications for broadcasting from a laptop
If standard tools don't work properly, you can use specialized software. There are many programs that implement DLNA and AirPlay for Windows, and they often have more flexible buffering settings.
A popular solution is to use media servers like Plex or Kodi, which allows you to install the server part on your laptop and the client part on your TV (or the built-in one), and you can create convenient libraries of movies and TV shows.
Another option is utilities like LetsView or ApowerMirror, which allow you to not only broadcast an image, but also control your computer from the TV remote, although this feature can work with a delay.
| Method | Delay. | Quality. | Difficulty |
|---|---|---|---|
| Miracast | Low. | High. | Low. |
| ChromeCast | Medium | High. | Low. |
| DLNA (Player) | No. | Original | Medium |
| HDMI (Cable) | No. | Original | Low. |
The choice of the particular application depends on your tasks, and for presentations, solutions with minimal latency are better suited, and for watching movies, those that know how to buffer the flow to eliminate jerks.
Setting up a projector in Windows 10 and 11
Newer versions of Windows have a "Project to this PC" feature that turns a laptop into a receiver, but we need the opposite. However, the settings in this menu affect how the system searches for external displays. Check if detection is enabled.
Go to Settings → System → Project on this PC. Even if you don't plan to receive the signal, visibility settings can be helpful here. Make sure you choose "Available everywhere" or "Available on secure networks."
Also in the Related Settings section, look for a link to Connection Settings, where you can reset the device detection cache if the list of available TVs has stopped updating or displays old, already deleted devices.
💡
Rebooting the SSDP Detection Service in Windows can solve the problem with missing devices in the list of wireless displays.
Remember that wireless adapter drivers also play a role: Outdated Wi-Fi module drivers may not work properly with new encryption protocols or media transmission standards.
Solution: TV can't see laptop
One of the most common problems is when devices are turned on, Wi-Fi works, but search doesn't work, most often it's because of the Windows firewall settings or the antivirus settings, and you need to add an exclusion rule for a private network.
Check the network type in Windows. If the network is marked as "Public", the system blocks the detection of other devices for security. Switch the network profile to "Private" in the Wi-Fi connection settings.
⚠️ Note: Antivirus packages (Kaspersky, ESET, Avast) often have its own network screen that blocks Miracast protocols and DLNA regardless of the Windows settings.
If the problem persists, try restarting the router. Long-term operation of the router can lead to overflow of the ARP table or IP-address conflicts, which prevents devices from finding each other on the local network.
💡
90% of connection problems are solved by switching the network profile to Private and checking the firewall settings.
In rare cases, network resets can be helpful. In Windows 10/11, you can do this through the command line with administrator rights by resetting the TCP/IP stack and the DNS cache.
