• With the left key, reduce the brightness until
it matches the baseline display.
• Select the individual colors and adjust the
amounts of Red, Green and Blue to achieve
the best match in color and brightness to the
baseline display.
14. When each display matches in white, change
T
EST
PATTERN
to Gray so the displays show an internal
gray pattern.
• The gray values range from 0 to 15, and they
are all now set at 7. Therefore, gray can be
adjusted up and down. Choose which dis-
play has a middle brightness and that has
very little color in gray. This is the display
you will match to. It
does not have to be the
same as the display chosen for white bal-
ance.
15. When the displays match in gray, turn off the test
pattern on each display with the top item in the
COLOR BALANCE
menu.
COPY TO CLIPBOARD
will save all the current settings to a
temporary memory. You can then make more
adjustments to see if it gets better or worse. R
ECALL
FROM
C
LIPBOARD
will restore these saved settings. The
clipboard is only for testing. These values are not saved
when AC power is off.
While color balancing, change the White value by a lot,
not just one step. It’s difficult to see one step in White. A
large change will tell you if you are heading in the right
direction.
If you can’t decide which way to go or how to get this
display closer to the others, try any change. If it is the
wrong change, it will be quickly obvious, and you can
go back. Use the clipboard.
Color balance values are saved for all input sources in
the same memory location. Color balance is the same
for all sources
When adjusting
WHITE BALANCE
-
ALL
you may not see all
three of the red, green, and blue numbers decrement or
increment. This because the
ALL
choice adjusts the
colors in proportion to each other, so that the color
remains constant as you adjust the brightness. For
example, if you have the color set at Red-100 Green-80
and Blue-40 and adjust down 10 clicks, you will wind
up with Red-90, green-72 and Blue-36. The color has
remained the same and only the brightness has
changed. Green and blue did not change on every one
of the ten clicks.
The
TD61
has a feature that allows a boost in the
whites. When this is on, Color Balance will become
more difficult but will allow for brighter whites.
The
TD61
has a gamma control which allows the user
to choose between Video and Film gamma in the color
balance menu.
