Modern televisions LG Smart TV offer a variety of ways to interact with smartphones and tablets, but it is the technology Wi-Fi Direct remains one of the most reliable options for direct media streaming without a router. After successfully pairing devices for the first time, many users wonder: what to do next and how to make the most of this connection? Unlike traditional DLNA, this connection is established directly between the screen and the device, ensuring high data transfer speeds and stable image quality.
It's important to understand that once successfully connected, your smartphone and TV form a local network, allowing them to "see" each other even when there's no internet access. This makes this method ideal for showing presentations in offices or watching movies at the dacha, where Wi-Fi coverage may be weak or nonexistent. However, for multimedia features to function correctly, additional configuration of intermedia apps or built-in services is often required. LG Content Store.
In this guide, we'll cover all the steps involved in using the technology after pairing. You'll learn how to mirror your screen, which apps are best for managing media files, and how to avoid common errors that occur when trying to play heavy 4K content. We'll also pay special attention to the protocol's nuances. Miracast, which is often a software implementation of Wi-Fi Direct in the South Korean manufacturer's ecosystem.
The principle of operation of the technology after the initial pairing
Once you've entered the PIN and the devices have "shaked hands," a secure P2P (Peer-to-Peer) communication channel is established between them. At this point, your TV LG WebOS or an older model with NetCast It takes on the role of either a client or an access point, depending on the chipset architecture. The smartphone stops using mobile data to stream video files to the screen, switching to a high-speed local channel.
The key here is that the connection doesn't immediately break after transferring a single file. The system remembers the trusted device, and the next time you start the data transfer function, you usually don't need to re-enter the password. This creates a seamless experience: you open the gallery on your phone, select a photo, and it appears on the big screen almost instantly. However, it's worth remembering that Wi-Fi Direct consumes significant battery power from both devices.
It's worth noting an important technical detail: although the communication channel has already been established, not all applications can automatically detect the TV. Some programs require manual selection of the device from the list of available devices, even if the connection is active. This is due to the implementation specifics of the Service Discovery protocol in different operating system versions. Android And iOS.
⚠️ Note: If after successful pairing the TV stops detecting the phone after 10-15 minutes of inactivity, check the power saving settings. Some models LG automatically disable the Wi-Fi Direct module when the screen goes into standby mode, breaking the direct connection.
Mirror your smartphone screen using Miracast and Screen Share
The most requested function after connection is image duplication, or Screen MirroringOn TV LG This function is often called Screen Share and is based on the standard MiracastTo start broadcasting, you don't need any wires; just launch the corresponding app on your smartphone.

The quality of the transmitted image directly depends on the congestion in the wireless range. If you are broadcasting video in a resolution 1920×1080 or 4K, make sure there are no physical barriers between your phone and TV. Latency when using Miracast Typically it ranges from 50 to 150 ms, which is quite comfortable for watching videos, but can be noticeable in fast-paced games.
For users who plan to use this feature frequently, it is useful to know about the existence of the "Sound Only" or "Screen Off" mode. Some models LG allow you to broadcast an audio stream or a photo slideshow, turning off the main TV screen to save the matrix resource, although this is more related to the function Music Player.
Using the LG TV Plus app to control

Multimedia transfer: photos, videos, and music
One of the main purposes of creating a direct connection is to exchange large files. Unlike Bluetooth, which is too slow for video, Wi-Fi Direct allows you to transfer files of several gigabytes in size in a matter of minutes. To do this, use the TV LG the built-in application is often used Photos and videos or Media Linker (on older models).

| Video (MKV) | Full | H.264 / VP9 | up to 80 Mbps |
| Audio (FLAC) | Full | Lossless | Unlimited |
| Photo (RAW) | Partial | JPEG preferred | N/A |
⚠️ Note: When transferring video files larger than 2GB using some Android file managers, an error may occur. In this case, use the built-in "Cast" feature within the video player rather than transferring the file.
Configuring connection and security settings
Although Wi-Fi Direct While convenient, it requires careful attention to security settings. By default, the connection is secured by the protocol WPA2, but the network name (SSID) and password can often be changed in the TV menu. This is useful if you're in a location with a lot of devices to avoid connection confusion.
To change the settings, go to the menu: Settings → All settings → Network → Wi-Fi DirectHere you can:
- 🔒 Change the device name so that it is easily recognized in the list (for example, "LG_LivingRoom").
- 🔑 Generate a new password to connect new devices.
- 📜 View the list of previously connected devices and remove unnecessary ones.
- 📶 Toggle visibility mode (on/off).
It's recommended to regularly clear the list of paired devices, especially if you've used the TV at a party or in the office. This will prevent your personal devices from automatically connecting to other people's TVs in the future, and vice versa. It's also worth keeping in mind that active visibility mode may slightly increase the TV's power consumption in standby mode.
