Many users encounter difficulties during initial setup, confusing various data transfer protocols. Unlike standard DLNA, Wi-Fi Direct creates a direct connection between the TV and smartphone, which ensures a more stable transmission of heavy video streams without delays. In this article, we will examine in detail the procedure for various operating systems and equipment models.
Before we move on to practical steps, it is worth noting that the webOS interface on TVs LG The specifications may vary slightly depending on the year of manufacture of the device. However, the basic operating principles of the communication module remain the same. Understanding the physics of the process will help you avoid common mistakes and quickly establish communication.
Operating principles of the technology and device compatibility
Technology Wi-Fi Direct is based on IEEE 802.11 standards, allowing devices to connect directly to each other without going through an access point. In the context of the ecosystem LG This means your smartphone and TV form a local network, with one device acting as a client and the other as an access point. This ensures high data transfer rates, sufficient for streaming high-definition video.
It's important to understand that not all apps support direct streaming via this protocol equally. For example, built-in smartphone galleries often use standard detection methods, while streaming services may employ their own algorithms. casting. Televisions LG They are equipped with a built-in module that supports multiple profiles, but for full functionality they often require additional software on the mobile device.

They offer more flexible control settings and often perform better at encoding video streams, reducing input lag.
What to do if Android doesn't see the TV?
If the search yields no results, check whether Incognito mode for Wi-Fi (MAC address randomization) is enabled on your smartphone. Try disabling this feature for your current network or temporarily disabling mobile data (4G/5G), as some smartphones prioritize mobile data and ignore local device searches.
Setting up broadcasting from Apple devices (iOS)
Equipment owners Apple are in an advantageous position due to protocol integration AirPlay 2 directly into the webOS operating system. You don't need any additional apps to connect if your TV LG This feature is supported by iOS 11 (2019 and newer models, as well as some earlier models after an update). The process is simple: use the standard "Screen Mirroring" menu in the iOS Control Center.
If automatic detection doesn't work, you need to check your TV settings. Go to Settings → Connection → Air Play and iTunes (or a similar option in your version of webOS) and make sure the feature is enabled. You can also set up a code entry requirement every time you connect, which increases security. safety your home network from random connections from neighbors.
| Parameter | Description | Recommended value |
|---|---|---|
| AirPlay | Main function switch | On |
| Require code | Protection from unauthorized access | First time |
| Access | Who can connect? | All |
