Apple Final Cut Pro 7 - Manual (Page 1334)

Note: The contrast control adjusts how much the RGB signals are scaled.
When monitor brightness and
contrast are properly adjusted,
this strip should barely be
visible above black.
When adjusting the contrast, also watch the white square in the lower left. If the contrast
is too high, the white square appears to “spill” into the surrounding squares. Adjust the
contrast until the luma of the white square no longer spills into surrounding squares.
7 Once you have finished adjusting luma settings, turn up the chroma control to the middle
(detent) position.
Note: Some knobs stop subtly at a default position. This is known as the detent position
of the knob.
8 Press the “blue only” button on the front of your monitor.
Note: This button is usually available only on professional monitors.
Notice how all of the different-colored bars turn into alternating light and dark ones.
• If your monitor is correctly calibrated: All the gray bars will be evenly gray, and all the
black bars evenly black.
• If the two outer gray bars don’t match: Adjust the chroma control of the monitor until
they do. Then adjust the phase control to even out the inner bars.
When the phase (similar
to hue) of the monitor is
correctly adjusted, you
should see alternating
bars of gray and black,
as shown.
