The main advantage of this method is the ability to control playback: you can pause, rewind, or change the volume directly from your smartphone screen, without having to look for the remote control.
Using DLNA to Play Your Media Library
Technology DLNA (Digital Living Network Alliance) allows you to share media files between devices on the same network without having to mirror your screen. This is a great way to watch a movie downloaded to your phone or show a presentation.
Most modern smartphones have a built-in DLNA server or client. However, for convenience, it is recommended to use specialized media player apps, such as VLC for Mobile or BubbleUPnPThese programs can automatically find compatible TVs on the network.
Launch the selected player on your smartphone and open the desired video or photo. In the playback interface, find the streaming icon (usually a rectangle with waves in the corner). Click it and select your TV. LG from the list of renderers.
⚠️ Note: When using DLNA, your phone acts as a controller. If you close the player app or your smartphone screen goes dark (depending on your power saving settings), playback on the TV may be interrupted.
The quality of the stream transmitted via DLNA is usually very high, as the TV decodes the video file itself, receiving only raw data over the network. This reduces the load on the smartphone's processor and minimizes device heating.
If your TV can't detect your phone, check your router's firewall settings. Sometimes your smartphone's antivirus software can block incoming connections from your TV, considering them suspicious.
Setting up Wi-Fi Direct for a direct connection
In situations where your home Wi-Fi network is overloaded or there is no access to the router, you can use the technology Wi-Fi DirectIt allows you to create a direct connection between your phone and TV. LG, bypassing the router.
Activate Wi-Fi Direct on your TV. The setup path may vary: Settings → All settings → Connections → Wi-Fi DirectEnable the feature and remember the device name that appears on the screen.
On your smartphone, also enable Wi-Fi Direct in the wireless network settings. After scanning, your TV will appear in the list of available devices. Tap it to pair.
What is the difference between Wi-Fi Direct and regular Wi-Fi?
Wi-Fi Direct creates a separate access point between two devices. Data transfer speeds can be higher because traffic doesn't go through the router, but the smartphone may lose internet access if it doesn't support dual Wi-Fi channels.
Once successfully connected, your phone and TV are connected to the same virtual local area network (VLAN). You can now use any streaming methods (DLNA, Miracast) as if they were connected to a regular router.
This method is especially useful when displaying content in offices or hotels, where the corporate network may have restrictions on the transfer of large amounts of data or require complex authorization.
Troubleshooting and fixing connection errors
Despite the simplicity of the technology, users often encounter issues where the TV doesn't detect the phone or the connection constantly drops. The most common cause lies in the router's security settings or client isolation.
Check if the feature is enabled AP Isolation (Access Point Isolation) in your router settings. If enabled, devices connected to the Wi-Fi network cannot "see" each other, making broadcasting impossible. This option should be disabled.
- 🔄 Reboot: Turn your router, TV, and smartphone off and on again. This clears the network settings cache.
- 📡 Signal frequency: Make sure both devices are connected to the same frequency (either both to 2.4 GHz or both to 5 GHz).
- 🛡️ Antivirus: Temporarily disable the firewall on your smartphone to test.
- 📺 Software update: Check for system updates WebOS in the TV menu.
☑️ Diagnostic checklist
If you see a picture but no sound, check the audio output settings on your phone.
