You can turn
on Adaptive Light Output to automatically adjust the brightness of
your projector's light source based on the brightness of the
surroundings.
Note: You can
also manually adjust the brightness of your projector's light
source by using the Brightness buttons on the remote control.
Manually set brightness levels take priority over automatically set
levels. This setting is not an absolute value as it varies relative
to the manually set brightness level. This setting may not work
properly if you use the projector in direct sunlight or with bright
fluorescent lights.
