When I attempt to stream content on Plex, I get no higher resolution than 720p. I found that by default, the Plex app on the LG television, the Windows App, and the browser always defaulted to 720p. I changed it to Maximum or Original on everything but I still don’t get anything better than 720p.
I tried creating another account, but with the new one it doesn’t even have the playback settings available to change.
