The market offers a variety of free and paid apps that expand functionality.
One of the most popular solutions is the application AirScreen or TV Cast, which are installed directly on the TV via the Google Play store. They emulate AirPlay signal reception (for Apple devices) or provide a convenient interface for transferring photos and videos from a computer. To manage files on a PC, you can use the program 5KPlayer or VLC Media Player with renderer function.
Below is a table comparing popular connection methods based on key parameters:

Troubleshooting and
Even with proper setup, situations may arise where the laptop doesn't detect the TV or the connection constantly drops. Most often, the problem lies with the Windows Firewall settings, which block incoming connections from the TV. Ensure that your network is marked as "Private" and not "Public."
If the image is choppy or broken into blocks, this is a clear sign of insufficient bandwidth. Try disconnecting other devices from the Wi-Fi or reducing the quality of the streaming video. It's also worth checking whether the channel is being overloaded by neighboring routers and, if necessary, changing the broadcast channel in the router settings.
⚠️ Attention: TV operating system interfaces and firmware are subject to update. Menu item locations and function names may differ slightly from those described in the manual. Always consult the manufacturer's latest manuals if the standard path doesn't work.

Frequently Asked Questions (FAQ)
Is it possible to connect a laptop to Xiaomi TV without a router?
Yes, many modern laptops and TVs support Wi-Fi Direct technology. This technology allows devices to connect directly to each other, creating their own network. However, data transfer speeds may be lower than those achieved through a dedicated router.
Why is there no sound when connected via Wi-Fi?
Check your sound settings in Windows. Click the speaker icon in the system tray, select the output device, and make sure your TV is selected (e.g., MI TV 4S), not the laptop speakers. Sometimes you need to restart the application after changing the output device.
Is the image lagging when playing over Wi-Fi?
