Wirelessly connecting your TV to your computer via Wi-Fi opens up a wealth of possibilities, from streaming high-definition movies to playing games on the big screen. However, many users encounter compatibility issues, image lag, or setup difficulties. This article will help you understand all the nuances, from choosing the right protocol to troubleshooting common errors.
We will consider 5 main ways Connections: from standard Windows functions to specialized apps. You'll find out which method is best for your TV (Samsung, LG, Sony or Xiaomi), how to minimize delays when watching videos, and what to do if devices can't "see" each other. We'll pay special attention to setting up Miracast And DLNA — the most universal technologies for modern TVs.
Before you begin setting up, please check two key conditions: both devices must be connected to one Wi-Fi network (or the router must support WPS for a direct connection), and the computer has the latest drivers for the video card. If you are using a laptop, make sure the mode Airplane Mode disabled - it blocks all wireless connections.
1. Connecting via Miracast: A Universal Method for Windows 10/11
Miracast — is a wireless image transmission standard supported by most modern TVs and Windows starting with version 8.1. The main advantage of the method is minimal delays (up to 50 ms), which is critical for gaming or watching dynamic videos.

802.11ac(for stable 4K transmission) - 🔒 Are firewalls disabled (sometimes they block Miracast)
⚠️ Note: On some laptops with hybrid graphics (NVIDIA Optimus or AMD SwitchableMiracast may be unstable. If this occurs, force switching to the discrete graphics card in the Graphics Control Panel.
For users Windows 11 An improved version of the protocol is available - Miracast over Infrastructure, which allows you to share your screen even if your devices are connected to different networks (provided your router supports it). To activate this mode, enter the following in the command line:

FAQ: Frequently asked questions about connecting a TV to a PC via Wi-Fi
Is it possible to connect an old TV without Smart TV?
Yes, but you will need an additional device:
- 📦 Android TV Box (For example, Xiaomi Mi Box S) - connects via HDMI
- 🖥️ Google Chromecast — for streaming via Wi-Fi
- 🔌 Wi-Fi adapter with HDMI (For example, Microsoft Wireless Display Adapter)
The minimum price for such a solution is 2,000 rubles. Keep in mind that older TVs may not support resolutions higher than 1080p.
Which method is best for watching 4K movies?
For 4K content it is optimal to use DLNA with the following settings:
- 📶 Router with support
802.11ac(orWi-Fi 6) - 🖥️ The PC is connected to the router via Ethernet
- 📁 Files in format
MKVwith codecH.265 (HEVC)
Miracast for 4K only works at 30Hz, which may cause image stuttering.
Why is there no sound when connecting via Miracast?
Sound problems are usually related to:
- 🔊 Incompatible audio drivers (update Realtek Audio)
- 🎵 Windows settings (check
Playback devices) - 📵 TV limitations (some models only transmit sound via HDMI ARC)
Solution: In the Sound Control Panel, select Digital audio (HDMI) as the default device.
