+
+         Sets an upper bound for how long the screen will dim before the device goes
+         to sleep when there is no user activity.  The dim duration is subtracted from
+         the overall screen off timeout to determine the screen dim timeout.
+         When the screen dim timeout expires, the screen will dim, shortly thereafter
+         the device will go to sleep.
+
+         If the screen off timeout is very short, the dim duration may be reduced
+         proportionally.  See config_maximumScreenDimRatio.
+
+         This value may be zero in which case the screen will not dim before the
+         device goes to sleep.

+
+         This resource is similar to config_maximumScreenDimDuration but the maximum
+         screen dim duration is defined as a ratio of the overall screen off timeout
+         instead of as an absolute value in milliseconds.  This is useful for reducing
+         the dim duration when the screen off timeout is very short.
+
+         When computing the screen dim duration, the power manager uses the lesser
+         of the effective durations expressed by config_maximumScreenDimDuration and
+         config_maximumScreenDimRatio.
+
+         This value must be between 0% and 100%.  If the value is zero, the screen will not
+         dim before the device goes to sleep.
