  That's good wording. The only issue I see is that a display arrangement, which has the display saved in the past with the second option selected will keep this display's values even if later in a different display arrangement the display values get changed with the first option selected. But the first option suggests that **all** display arrangements will be set to the configured values.
  
    Save screen: (o) For all display arrangements with non-unique screen values
                 ( ) Uniquely for the current display arrangement
  
  That's more complicated though.
