It is important to distinguish between this technology and the regular Screen Share/Miracast mode, although they often use the same hardware resources. Wi-Fi Direct — is a fundamental connection protocol, while Miracast is a software add-on for mirroring. TVs LG use this protocol as a basis for the application LG TV Plus and functions Smart View.
Equipment preparation and compatibility testing
Before attempting to establish a connection, you must ensure that both devices support the stated standard. Almost all modern models LG Smart TV, released after 2012, are equipped with a built-in module with support Direct modeThe mobile device must also have a corresponding adapter, which is standard for mid-range and high-end Android smartphones, as well as many tablets.

Frequently Asked Questions (FAQ)
Why can't my LG TV see my phone in Wi-Fi Direct mode?
Make sure Wi-Fi is enabled on your phone and you're close enough to the TV. Check if AP Isolation mode is enabled on your router, which can block direct connections between devices even if they're connected to the same network. Also, try rebooting both devices.
Is it possible to play games on a phone with the image output to a TV?
Yes, this is possible using screen mirroring (Miracast/Smart View). However, there may be an input lag between pressing a button on the phone and the action on the screen, making this method unsuitable for fast-paced shooters, but perfectly suitable for turn-based strategy games or quiz games.
Does Wi-Fi Direct reduce internet speed on other devices?
Since Wi-Fi Direct creates a separate communication channel, it theoretically shouldn't significantly impact the main network if the TV's Wi-Fi module is dual-band. However, if a single radio module is used for all functions, there may be a slight signal or speed degradation in the overall network due to frequency switching.
Is internet required for Wi-Fi Direct to work?
No, you don't need an internet connection. Wi-Fi Direct creates a local network between devices. You can transfer files or stream videos from your phone to your TV without accessing the internet, saving data and working even if your internet provider shuts down.
