In this post here I am using this converter to display my firestick to my TV it was hard to find a converter that I could confirm would output 480i it actually has a toggle button for different output resolutions. Problem is Firestick only outputs in a 16:9 aspect ratio so my way to get around this was to run my Plex server (using the app ‘PlexKodiConnect’ not the addon version because it bypasses Kodi’s player and any other apps I could through Kodi because it has a built in aspect ratio correction that is pretty adjustable. It works pretty well once all set up.
