LG with the operating system WebOS, and we will also consider the nuances of connecting smartphones based on Android And iOSYou'll learn how to properly configure visibility settings and which applications may be required for stable operation.
How Wi-Fi Direct works in LG TVs
Technology Wi-Fi Direct is a wireless communication standard that allows devices to connect directly to each other without going through an access point. In the context of televisions, LG This means your smartphone sees the TV as a separate wireless network. When connected, the phone uses its Wi-Fi module to transmit video streams or files directly to the receiver.
It's important to understand the difference between regular Wi-Fi and a Direct connection. When using a router, data passes through it, which can create a load on the network and depends on the router's signal quality. A Direct connection Peer-to-Peer Eliminates this middleman by creating a dedicated channel. This is especially useful if your home network is overloaded or your router is located far from the living room.
⚠️ Please note: When connected via Wi-Fi Direct, your mobile phone may be disconnected from the internet because the Wi-Fi module is busy transmitting data to the TV. Download any necessary content in advance or use your mobile data to access the network.
Televisions LG with support Smart TV They have a built-in module that emulates an access point. When you activate this feature on your TV, it begins broadcasting a special signal.

Instructions for Android users
Owners of smartphones based on Android have several connection methods. Most modern manufacturers (Samsung, Xiaomi, Huawei) have a built-in broadcasting function, which is often called Smart View, Broadcast or Wireless monitorThis method does not require installing additional software.

It's worth noting that some app features may require both devices to be on the same Wi-Fi network created by the router. In this case, Wi-Fi Direct mode is used as a backup channel or for initial setup.
Solutions to common problems and errors
Despite the simplicity of the technology, users may encounter difficulties. The most common issue is that the phone doesn't detect the TV. Make sure the connection standby menu is open on the TV. In sleep mode or in screen-off mode (while the TV is on), searching may not work.
The second problem is an intermittent connection or poor picture quality. This is often due to interference or channel congestion. Try disabling Bluetooth on your phone, as it operates on the same 2.4 GHz frequency and can cause interference. Restarting the Wi-Fi module on both devices also helps.
- 📱 Reboot: Turn Wi-Fi off and on on your phone, and also reboot your TV through the menu (
Settings → General → Reset to factory settings- only if other methods do not help). - 🔄 Software update: Check for updates for your TV LGThe manufacturer frequently releases patches that improve the stability of the Wi-Fi module.
- 🛡️ Antivirus: On some Android smartphones, aggressive security settings may block the ability to search for devices on the local network. Check the permissions for the "Cast" feature.
If all else fails, try resetting your TV's network settings. This will delete all saved Wi-Fi passwords and connected device lists, often solving network stack glitches.
What should I do if the connection keeps dropping?
Frequent connection drops may indicate a weak signal or an IP address conflict. Try manually setting a static IP address for the TV in your router settings (if you're using a network) or disable power saving on your phone, which may disable Wi-Fi to conserve battery life.
Can I play games on my phone via Wi-Fi Direct?
Technically, it's possible, but input lag over a wireless connection can be 100 ms or higher. While this isn't a significant issue for turn-based strategy or card games, it's not suitable for shooters or racing games due to the resulting desynchronization.
Does Wi-Fi Direct affect internet speed?
Wi-Fi Direct itself doesn't use the internet; it creates a local network. However, if your phone switches to a Direct connection, it loses internet access via Wi-Fi. Mobile data (4G/5G) remains available if enabled.
What is the maximum resolution supported by the broadcast?
Resolution depends on the TV and phone model. Full HD (1080p) is typically supported. If both devices support 4K and have a powerful processor, 4K streaming is possible, but this will require a very good signal and may drain the phone's battery more.
Do I need a password to connect?
When connecting for the first time, an LG TV almost always requires confirmation. A 4-digit code appears on the TV screen, which you must enter on your phone or request confirmation via the remote. This prevents neighbors from accidentally or intentionally streaming content to your screen.
