Display Mode/Resolution Changes
    The resolutions do not represent display modes any more. The native display mode is used. If your desktop uses your monitor native resolution then the game doesn't change it. You can choose at which resolution the game will be rendered. Diablo III tries to figure out the native resolution and generates 10 resolutions based on that.

    For example: If your resolution uses 1920 x 1080, 16:9 ratio; it will offer resolutions based on the same ratio aspect:
    • 1066x600 (wide)
    • 1180x664 (wide)
    • 1284x772 (wide)
    • 1380x776 (wide)
    • 1468x826 (wide)
    • 1552x874 (wide)
    • 1632x918 (wide)
    • 1710x962 (wide)
    • 1782x1002 (wide)
    • 1920x1080 (wide)

If you have issues with resolutions not being generated correctly, please try reverting to the older display mode, where it is limited but the current resolution of your OS.
    1. Make sure Diablo III is closed.
    2. Open Terminal (/Applications/Utilities)
    3. Copy/Paste the following command:
    defaults write com.blizzard.diablo3 DesktopModeIsDefault 14. Press Return. (There should be no output if done correctly)
    5. Exit Terminal.

This should now allow you to display resolutions based on your current OS resolution.
