• White Balance
Regardless of the change in ambient light, the human eye is equipped with an automatic adjustment
mechanism that makes a white object appears white and black object black. However, since no
machine has such an incredible innate feature, you may need to make certain adjustments to the
projector's settings when the ambient light changes so that the picture will appear closer to the
actual colors.
Gain
This refers to the control of color imbalance in the brighter areas of the projected picture. It is
recommended that you use an external test picture with many areas of white (i.e. an picture of
80IRE-window). If you notice minimal amount of red, green or blue in the gray areas, lower the
gain of the corresponding color accordingly. This function is used to increase or decrease the range
of color input for the entire picture.
Generally speaking, as gain increases, the contrast of the picture will become lower. By increasing
the offset, the picture brightness will become lower.
Offset
This refers to the control of color imbalance in the darker areas of the projected picture. It is
recommended that you use an external test picture with many areas of dark and gray colors (i.e. an
picture of 30IRE-window). If you notice minimal amount of red, green or blue in the gray areas,
adjust the offset of the corresponding color accordingly. This function will shift the entire color
spectrum for the whole picture and change its brightness.
