WmiSetALSBrightnessState method of the WmiMonitorBrightnessMethods class

The WmiSetALSBrightnessState method is used to control the ambient light sensor brightness state. If an active brightness override was established by using the WmiSetBrightness method, that override will take precedence over the ALS brightness set by using this method. For an enabled ALS brightness override to take effect, the brightness policy has to be reverted by using the WmiRevertToPolicyBrightness method.

   boolean State

Parameters

State

ALS brightness state. False disables the ALS brightness override and true enables it.
