4-6-7. LIGHT MODE
Adjust the light source output of the projector.
BOOST
The picture becomes brighter than the [NORMAL] mode.
However, the power consumption will increase.
The life of the optical components may also be shortened depending on the operating environment.
NORMAL
Brightness changes to 100% and the screen becomes bright.
ECO
The brightness becomes about 80% of the brightness in the [NORMAL] mode.
The operating noise and power consumption will also decrease due to control of the cooling fan ac-
cording to the brightness.
TIP:
• You can check the light hours used from [INFO.] → [LIGHT HOURS USED] in the on-screen menu. (→ page 68)
• If there is no input signal (blue, black or logo display) for about 30 seconds, the mode automatically switches to [ECO]. After this,
when the projector detects an input signal, the [ECO] mode returns to the previously set mode.
• The projector is equipped with a function to detect the pressure and temperature and control the output.
When used in a location where the altitude or temperature is high, the brightness decreases regardless of the [LIGHT MODE]
setting. This mode is called the "Forced ECO MODE".
When "Forced ECO MODE" is selected, the screen becomes slightly darker, and the LIGHT indicator and TEMP. indicator lights
up in orange.
In addition, in the "Forced ECO MODE", the [LIGHT MODE] → [BOOST] function will be disabled even when set.
The "Forced ECO MODE" conditions and output are as follows.
Altitude \ Temperature
2,438 m – 4,200 m
1,219 m – 2,438 m
0 m – 1,219 m
4-6-8. LIGHT ADJUST (LIGHT MODE)
When the mode is set to [NORMAL] in [LIGHT MODE], the brightness can be adjusted within a range of 30% to 100%
(in 1% increments).
4-6-9. CONSTANT BRIGHTNESS (LIGHT MODE)
Controls the brightness so that it is kept constant based on the brightness in effect at the time [ON] is selected. The
adjustment value will be saved until [CONSTANT BRIGHTNESS] is set to [OFF] even if the power is turned off.
• To re-adjust the brightness, turn this setting [OFF] once before making further adjustments.
NOTE:
• [CONSTANT BRIGHTNESS] is a function to keep the brightness constant. The color will not be fixed.
TIP:
• When projecting multiple projectors in combination, we recommend that you adjust the brightness setting so that the brightness
is reduced slightly and then set [CONSTANT BRIGHTNESS] to [ON].
4-6-10. BACKGROUND
Select the background color when there is no input signal.
You can select either blue, black, or the NEC logo.
NOTE:
• [BACKGROUND] will not be changed even if [RESET ALL] is performed.
