TIP:
• When using multi-screen projection, it is recommended to adjust the brightness to a slightly lower level, then setting the [CON-
STANT BRIGHTNESS] mode to [ON].
[REF. WHITE BALANCE]
This feature allows you to adjust the white balance for all signals.
The white and black levels of the signal are adjusted for optimum color reproduction.
Uniformity is also adjusted when the redness (R) and blueness (B) of the white color in the screen's horizontal (left/
right) direction are uneven.
CONTRAST R/CONTRAST G/CONTRAST B
.............................. These adjust the picture's white color.
BRIGHTNESS R/BRIGHTNESS G/BRIGHTNESS B
.............................. These adjust the picture's black color.
UNIFORMITY R ...... The further this is set to the + side, the stronger the redness on the left side of the picture (increasing
towards the left edge) and the weaker the redness on the right side of the picture (decreasing towards the
right edge).
This is reversed when set to the – side.
UNIFORMITY B ...... The further this is set to the + side, the stronger the blueness on the left side of the picture (increasing
towards the left edge) and the weaker the blueness on the right side of the picture (decreasing towards the
right edge).
This is reversed when set to the – side.
[STATIC CONVERGENCE]
This features allows you to adjust for color deviation in the picture.
This can be adjusted in units of −3 to 0 pixel in the horizontal direction for HORIZONTAL R, G and B, in the vertical
direction for VERTICAL R, G and B.
Brightness can be adjusted in 1% increments from 30* to 100%.
[CONSTANT BRIGHTNESS] mode will be canceled.
Maintains the brightness that is in effect at the time [ON] is selected. Unless [OFF] is se-
lected, the same settings will remain in effect even when the projector is turned off.
• To re-adjust the brightness, first turn this setting OFF before making further adjustments.
NOTE:
• [CONSTANT BRIGHTNESS] mode is a function used to maintain the brightness at a constant
level. Color will not be fixed.
