Adjustment Of Luminance (Brightness) And Energy-Saving Effect - NEC PA1004UL-W User Manual

3-4. Adjustment of luminance (brightness) and energy-saving effect

You can adjust the output of the unit to a range of 50–100% (in increments of 1%) and control the
brightness after adjustment to keep it constant. Also, set the [REF. LIGHT MODE] to [ECO1] or [ECO2]
to reduce the brightness and operating sound. By saving energy consumption, the CO
from this projector can be reduced. There are two ways to set the light mode.

the menu
The picture becomes brighter than the
[NORMAL] mode. However, the operating noise
and power consumption will also increase due
to control of the cooling fan according to the
brightness. The life of the optical components
may also be shortened depending on the
operating environment.
100% brightness
Alternatively, you can adjust the output from
50 to 100% using [REF. LIGHT ADJUST].
Brightness will be at about 80%.
The cooling fan will also slow down accord-
ingly.
Lower power consumption
Brightness will be at about 50%.
The cooling fan will also slow down accord-
ingly.
Lower power consumption considerably
