Black balance : In the projector, we will set the brightness for each color until we get a 0% light output

The changeover from min to max is indicated by the apparition of bright spots also called
“digital noise”
An alternative to a full screen White/black pattern is the standard gray scale pattern, the
white bar will be used for white balance and the black bar for black balance.

Black balance
1. Select a window and click on Adjust (a). (image 8-27)
The Input dialog box opens (b).
2. Click on Input balance (c).
A question dialog box is displayed (d). This box announces that special lookup tables are needed while
adjusting input balance. Click Yes to load these tables. A second question window opens (f) to ask if
the 2 bit test pattern must be switched on.
3. If the pattern must be switched on, click Yes (g).
If no pattern must be switched on, click No.
When yes or no is clicked, the input balance adjustment window opens (h).
4. Adjust the red black level on a minimal value
5. Select Black balance blue and adjust the blue black level on a minimal value.
Note: This minima l value is not necessary , provided that the 2 other colors are not influencing too
much the color to be adjusted, in fact the aim is to minimize the effect of the two other colors
since there is a risk of reaching too soon the 50% transition due to the contribution of these two
other colors signals.
