Our current app is available on 4K/UHD LG television models running the following system software:
webOS 3.0
webOS 3.5
webOS 4.0
webOS 5.0
No 720p or 1080p (“full HD”) sets are supported for our current app at this time.
Note: Due to root certificate limitations with the device OS itself, only webOS 5.0+ devices support secure connections with a personal Plex Media Server. To allow connections to a personal server, devices running earlier webOS versions must be set to Allow Insecure Connections in the TV app settings and the Plex Media Server must be set to Preferred for the Secure Connections preference.
