Black balance adjustment
Black balance adjustment
In order for the black to be reproduced accurately, the zero
levels of the three primary colors (RGB) are adjusted. If the
black balance has shifted out of adjustment, not only will the
black be reproduced poorly but the color tones of the entire
screen will also be degraded. Normally, the black balance
need not be re-adjusted, but it is necessary in the following
situations.
This adjustment m
ust be performed when using the
unit for the first time or when the unit has not been
used for a prolonged period.
The adjustment m
ust be performed when the ambient
temperature has changed significantly and at the
change of the seasons.
