[BRIGHTNESS CONTROL]
The projector is equipped with a brightness sensor to measure brightness and color of the light source, and
corrects brightness and white balance of the projected image according to the changes in brightness and color of
the light source.
By using this function while structuring the multi-display by combining the projected images from multiple
projectors, the change in the brightness and white balance for the whole multi-display can be reduced or hold
down the difference of the brightness and white balance to maintain uniformity, caused by the aging of the light
source.
Setting [BRIGHTNESS CONTROL GAIN]
Adjust the brightness when displaying multiple images using multiple projectors.
1) Press as to select [BRIGHTNESS CONTROL].
2) Press the <ENTER> button.

decrease.
20 % - 100 %
Press q.
The screen becomes darker.
Maximum correction will
increase.
Note
f When using only one projector, the value obtained by subtracting the value of the [BRIGHTNESS CONTROL GAIN] from 100 % is the
maximum amount of brightness correction. Brightness cannot be corrected through brightness control since the maximum amount of
correction becomes 0 % when [BRIGHTNESS CONTROL GAIN] is at 100 %.
f The luminance will not stabilize for eight minutes after turning on the light source. Perform the adjustment after at least eight minutes have
elapsed after starting the projection.
f The adjustment result of [BRIGHTNESS CONTROL GAIN] is reected in all of the video signal, internal test patterns, and on-screen menu.
f The [BRIGHTNESS CONTROL GAIN] setting is valid even when [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] is set to
[OFF].
