Android TV has no screen mirroring function
I've recently bought a Panasonic TX-50HX700E Android television. However, I can't find a simple way to mirror my Windows 10 laptop onto it. The TV doesn't seem to support Miracast and there is no mirroring app or anything in the settings about mirroring. My laptop definitely supports Miracast but can't detect the TV.
I can mirror using an HDMI cable, Chromecast or server software like Plex or Emby. However, these come with their own problems and inconveniences, such as not supporting Dolby Vision or being laggy/low resolution.
Is there any way I can mirror my laptop using Miracast or the other built-in Windows tools, please?
