The main advantage of using Wi-Fi connections The key features are portability and a clean interface. You can control playback of movies, presentations, or games from anywhere in the room, while the laptop is on the table. However, for stable operation, a number of technical requirements for network hardware and software must be met.
In this article, we'll take a detailed look at all current device synchronization methods, from built-in operating system functions to specialized applications. Both devices must be on the same Wi-Fi router subnet., otherwise detection will be impossible. This is a fundamental rule, and if violated, it most often leads to connection errors.
Technical requirements and equipment preparation
Before you begin setup, make sure your equipment meets the minimum requirements for transmitting high-definition video streams. TVs LG, released after 2014, as a rule, already have built-in support for the technology Miracast, which greatly simplifies the process.

Solving problems and delays
Wireless connections are always susceptible to external influences. The most common problem when connecting a laptop to a TV LG There's lag or intermittent connection interruptions. This can be annoying when watching videos and make gaming impossible.
The main cause of interference is often the congestion of the airwaves by neighboring Wi-Fi networks or the operation of household appliances in the range 2.4 GHzMicrowave ovens and Bluetooth devices can cause significant interference. Switching to a channel 5 GHz in the router settings usually solves this problem.
- 📶 Weak signal: Move the router closer to the TV or use a Wi-Fi repeater.
- 🔄 Connection lost: Reboot the router and both connected devices.
