This is especially convenient when the system unit is located far from the sofa or living room.
The process of synchronizing devices is based on standards Miracast, DLNA and built-in support Google ChromecastUnlike a wired connection, a wireless connection requires a stable router and proper configuration of both devices on the same local network. The user doesn't need to purchase additional adapters if the PC has a built-in Wi-Fi module.
In this article, we'll explore all available image streaming methods, troubleshoot common issues, and set up high-quality signal transmission. You'll learn how to turn your TV into a massive monitor for work or entertainment using only operating system software. Windows and built-in functions Android TV.
Equipment and network preparation requirements
Before you begin setup, you need to make sure your infrastructure is ready to transmit high-definition video streams. Wireless connection It's significantly more sensitive to interference and distance than a cable connection. If the router is in another room or behind thick walls, image quality may suffer from compression artifacts.
Both devices – the computer and the TV – must be connected to the same Wi-Fi network. Using a guest network or different frequencies (2.4 GHz vs. 5 GHz) on some routers may prevent devices from discovering each other. It is recommended to use the 5 GHz band to ensure sufficient channel throughput.
Check that your PC's network adapter drivers are up-to-date. Outdated software may not support the required media transfer protocols. Also, make sure your TV Xiaomi the latest firmware version is installed MIUI TV.
⚠️ Note: If your router has a "Client Isolation" feature, devices will not be able to see each other on the network. This mode is often enabled in public places, but is sometimes also enabled by default on home routers.
For a comfortable experience, make sure your computer's Wi-Fi signal doesn't drop below two bars. A weak signal will cause audio and video to become out of sync.
Using the built-in Projection feature in Windows
operating system Windows 10 And Windows 11 have native support for the technology Miracast, which allows you to broadcast your screen without installing third-party software. TVs Xiaomi with shell Android TV often support this protocol out of the box or through a built-in application.
To get started, press the key combination Win + K on your computer keyboard. The "Connection" panel will appear on the right side of the screen. If the TV is turned on and connected to the same network, it should appear in the list of available devices.

| Chromecast | Broadcast from a browser | Average | Up to 1080p/4K |
| DLNA | Viewing files | Absent | Original |
Using DLNA allows you to control playback with your TV remote, pausing or rewinding the video, which is not possible with simple screen mirroring.
Third-party programs for extended functionality
Standard tools are sometimes insufficient for specific tasks, such as game streaming or transmitting audio separately from video. In such cases, specialized utilities installed on a PC and, sometimes, on a TV, come to the rescue.
One of the most popular programs is AirScreen or LetsViewThey often perform more reliably than built-in Windows tools and offer more quality settings. The app is installed on the TV through the store. Google Play, and the client part is on the computer.

Troubleshooting and signal optimization
Even with proper setup, problems may still occur: connection drops, no sound, or low resolution. Most often, the cause is radio channel congestion or IP address conflicts.
Try rebooting your router, computer, and TV. A simple DHCP lease update often resolves the "invisibility" issue. Also, check if your antivirus or Windows Firewall is blocking your private network.
If the image is jerky, try lowering the output resolution on your PC. Transferring the image to 1920×1080 requires less than 3840×2160You can also try disabling vertical sync for the connection you're testing in the graphics settings.
In challenging situations where the Wi-Fi signal is weak, consider using Powerline adapters. They transmit internet through electrical wiring, allowing you to connect your TV via cable in places where there's no LAN outlet but power is available.
Why can't my Xiaomi TV detect my computer?
Most often, the problem is that the devices are on different subnets (for example, one on guest Wi-Fi, the other on the main one) or network discovery is disabled in Windows. Also, check if your antivirus software is blocking the connection.
Is it possible to transmit sound separately to the speakers?
Yes, if you use the DLNA protocol for video files, the audio will be output through the TV's audio system. When using screen mirroring (Miracast), the audio is also transmitted to the TV, but you can select the output device in the Windows sound settings.
Does connecting to a TV affect internet speed?
Yes, wirelessly streaming high-quality video consumes a significant portion of your Wi-Fi bandwidth. If someone is downloading files or playing online at the same time, this can cause lag for everyone on the network.
Do you need internet to connect?
Internet access is not required for Miracast and DLNA to work; only a local network is required (the router can even be used without a connection to a provider). However, internet access is required for Chromecast and smart TV features.
How to improve image quality when there are lags?
Move closer to the router, switch to the 5 GHz frequency, close background downloads on your PC, or lower the screen resolution in Windows display settings before connecting.
