| Quality | Depends on the signal | High | Original |
| Sound | It is transmitted | It is transmitted | It is transmitted |
Third-party programs and browsers
In some cases, built-in tools may be unstable or may not support certain file formats. This is where third-party solutions come in handy. One popular method is using a browser. Google Chrome, which can broadcast a tab or the entire screen to devices that support it. Chromecast (built into many LG models).

Features of sound transmission
When casting video, it's important that the audio also outputs to the TV, rather than remaining on the laptop. In Windows, when connecting via Miracast, audio switching often happens automatically.

Why is my TV not visible in the list of devices?
This could be caused by several reasons: the devices are connected to different networks (for example, one to a guest network and the other to the main network), client isolation is enabled on the router, or the TV's request-receiving feature is disabled.
