Why doesn't the app see the TV?
If your LG ThinQ TV isn't finding your TV, check if guest Wi-Fi mode is enabled on your router. Guest networks are often isolated from the local network where your smart devices are located. Also, make sure the app has permission to access your local network (especially relevant for iOS 14 and above).
Streaming via Google Home (Chromecast)
Many modern LG TVs come with built-in support Chromecast, which allows you to stream content directly from compatible apps. Unlike Miracast, the phone only acts as a remote control, and the TV downloads the video stream directly from the internet.

Troubleshooting connection issues
Despite the technology's refinement, glitches sometimes occur. If your TV doesn't detect your phone, first check firewall settings on the router. Antivirus programs on PCs connected to the same network can also block device detection.
A common problem is different subnets. If you have a complex network with multiple routers (a mesh system), make sure the devices aren't spread across different segments. Restarting the router often resolves IP address allocation issues.
If the image is choppy or has low resolution, reduce the load on your Wi-Fi channel. Disable downloads on other devices or switch your TV to the 5 GHz frequency, if possible.
⚠️ Attention: Menu interfaces and function names may vary slightly depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). Always consult the official documentation for your specific model if menu items do not match the description.
