It is called ‘Sort Title’.
You cannot switch sorting to the full title.
You can however influence how the sort title is generated, when media are added to your server.
There is a hidden preference, which articles/words are cut off from a full title to make the Sort Title.
If you empty out this list, the full title will be copied to the Sort Title.
You can use the attached .reg
file (unzip it, then double-click) to do it.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server]
"ArticleStrings"=""
the following will revert the setting to its default:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server]
"ArticleStrings"="the, die, das, der, a, an, el, la"
Changing this preference won’t affect all the items which are already in your Plex library, though.
