About color temperature
There are different kinds of white color. Color temperature is a way to show the differences in white. With the higher color temperature, white
area of the image appears reddish, with the lower color temperature, white area of the image appears bluish. This projector adjusts the color
temperature by changing the values of the blue and red contrasts.
To raise the color temperature:
Increase the CONTRAST B (blue) and decrease the CONTRAST R (red).
To reduce the color temperature:
Decrease the CONTRAST B (blue) and increase the CONTRAST R (red).
Important
• If you set all of CONTRAST R, G and B to negative value, the original brightness of the image can not be obtained even
when you maxmize CONTRAST in the IMAGE menu.
