  • Fenna,

    That's usually a sign you have the game set to use a refresh rate or resolution your monitor can't handle.

    Set the game to use windowed mode and then try setting the options to match what you want to use.

    To get it into windowed mode, open your My Documents folder and the Diablo III folder inside. You'll see a D3Prefs.txt file. Open it with Notepad and look for this line:

    DisplayModeWindowMode "0"

    Edit it to

    DisplayModeWindowMode "1"

    Save and exit and start the game up now.
