1. In a computing environment, a method of automatically changing a brightness of a display device, the method comprising:
while the display device is at a first brightness power output level, detecting a power saving event indicating that it is desirable to reduce overall power consumed by the display device;
as a result of detecting the power saving event, continuing to operate the display device at the first brightness power output level while attempting to identify a brightness power output level change triggering event, the first brightness power output level change triggering event is an event that is at least one of a change in ambient lighting or a change in screen output of the display device, the brightness power output level change triggering event is an event which masks changes to brightness power output level of the display device;
detecting the brightness power output level change triggering event; and
in response to detecting the brightness power output level change triggering event and the power saving event, changing the a the first brightness power output level of the display device during the brightness power output level change triggering event from the first brightness power output level to a second brightness power output level.
