For owners of devices with the shell EMUI or HarmonyOS you should make sure that the services Wireless Projection They work correctly. Sometimes resetting network settings is necessary if there were previously connection issues.
☑️ Checking device readiness
Make sure the Wi-Fi modules on both devices are enabled. Even if you don't plan to use your home network for data transfer, the radio module must be active to detect devices. In some cases, it may be useful to temporarily disable Bluetooth to avoid potential frequency conflicts, although modern chipsets handle both modes well.
Setting up an LG TV to receive a signal
To activate the signal reception mode on the TV LG You need to go to the settings menu using the remote control Magic Remote, press the button Settings (gear) or go to the main menu SmartFind the section responsible for connecting external devices.
Depending on the model and version of the operating system webOS, the path may look different. On newer models, look for the app Screen Share, and on older ones - a section Network or Connection Guide. Activating this mode puts the TV into a standby state for connection.
Path to the webOS 5.0+ menu:
Home → Inputs → Screen Share (or Mobile Devices)
After launching the app, the device name and possibly a PIN code to confirm the connection will appear on the TV screen. Make sure "Allow connection" is enabled. If the TV isn't visible to other devices, check that "Invisible" mode is not enabled in the network settings.
