SMPTE Color Bars, connect the Bars output to your
monitor. If your monitor has a BLUE ONLY switch,
set this switch to the BLUE ONLY position. If your
monitor does not have a BLUE ONLY switch, you can
still make the adjustments by looking at the monitor
through a blue filter. Two suitable filters are: Kodak
Wratten Blue 47B Gelatin filter and the Congo Blue
#181 filter from Lee Colortran Inc. (phone#: 201-256-
7666 or 818-843-1200). Looking at your monitor, you
will see alternating blue bars in the positions of the
75% bars (upper) and the reverse blue bars (lower).
Adjust the color intensity (saturation) so that the outer
left and outer right bars are the same brightness as
the corresponding bars just below them.
Chroma phase (tint or hue) is adjusted by matching
the brightness of the two center bars with the bars
just below, while rotating the tint control.
Return the BLUE ONLY switch to its normal position
(if you are using the blue filter it will no longer be
needed). Turn up the monitor brightness control. In
the lower right corner you will notice three gray bars
(the pluge pulse signal). These bars from left to right
are called BLACKER THAN BLACK (Black –4),
BLACK (Black), and WHITER THAN BLACK (Black
+4). To set brightness, adjust the brightness control
so that the WHITER THAN BLACK bar is visible and
that the BLACK bar and the BLACKER THAN BLACK
bar are not visible.
Note that the monitor should be viewed, and the
brightness adjusted, with the room lights somewhat
dimmed so that the colors won’t seem washed out.
The monitor might seem dimmer than you may be
used to, however, the colors will be more accurate at
