Using the Wall Color Correction [WALL COLOR]
This function allows for quick adaptive color correction in applications where the screen material is not white.
The following nine options are available.
Setting Lamp Mode to Normal or Eco [LAMP MODE]
This feature enables you to select two brightness modes of the lamp: Normal and Eco modes. The lamp life can be
extended by using the Eco mode. Selecting Eco mode decreases fan noise when compared to Normal mode.
Lamp Mode Description
This is the Default setting
NORMAL
(100% Brightness).
Select this mode to increase the
ECO lamp life (approx. 80% Brightness
light output)
NOTE: If the projector is overheated in Normal mode, there may be a case where the Lamp mode will be forced into the Eco mode
to protect the projector. This mode is called "forced Eco mode".
When the projector is in forced Eco mode, the picture brightness decreases. The LAMP indicator's steady green light indicates the
lamp is in Eco mode.
When the projector comes back to normal temperature, the Lamp mode returns to Normal mode.
In the forced Eco mode, changing [LAMP MODE] setting in the menu will not affect the actual Lamp mode.
