However, many users encounter difficulties: the TV doesn't detect the device, the connection drops, or the picture lags. In this article, we'll discuss how to set it up correctly. Wi-Fi Direct On TVs of different brands, what settings optimize data transfer, and what to do if something goes wrong.

It is important to understand that Wi-Fi Direct - it's not the same as Miracast or DLNAThe first creates a direct network between two devices (like Bluetooth, but faster), the second mirrors the screen using a wireless display protocol, and the third simply streams media files. We'll focus on these. Wi-Fi Direct, as it is a universal protocol supported by most modern TVs (Samsung, LG, Sony, Xiaomi etc.) and gadgets on Android/Windows.

Before you begin setting up, please check:

• 📺 Your TV supports Wi-Fi Direct (usually these are models not older than 2016).
• 📱 The source device (smartphone, laptop) is compatible with the technology (on Android — starting with version 4.0, Windows — from 8.1).
• 🔋 Both devices are charged to at least 50% - long-term data transfer drains the battery.

What is Wi-Fi Direct and how is it different from Miracast and DLNA?

Many people are confused Wi-Fi Direct with other wireless technologies, but each protocol has its own tasks:
