Hey Budw3iser,

The Diablo III setting can be reset back to the default settings through the Blizzard App.

    1) Select the game in the Blizzard app and click Options .
    2) Click Game Settings.
    3) Click on Reset In-Game Options.
    4) Click Done and launch the game normally.


They setting can also be reset by deleting the Diablo III folder in the your Windows Documents folder.
