Calibrate
the
Color
and Tint Controls
For this adjustment you'll need a colored filter
or
a display with a blue-only mode.
Most
displays do
not
have a blue-only mode,
but
it's
worth
checking the advanced
settings menus
and/
or
the owner's manual to see, because usually the blue-only
mode
is
easier
and
more accurate
than
using the filter.
If
your display does
not
have a blue-only mode, then the Spears
and
Munsil blue filter
is
the best
bet
as
it
allows the user to select IX, 2X,
or
3X
strength to help get an accurate calibration
with
different displays with different color spectra.
Other
blue filters from
other
companies like
THX,
Joe Kane,
or
Disney may also work,
but
be sure to check
if
they are completely cancelling the green channel before using them.
Checking
the Filter Strength
The colored filter works by showing you the blue color channel only, filtering
out
all the green
and
red. Typically any filter will remove enough red to be usable,
but
the color spectrum
of
the green channel
and
the blue channels overlap
on
nearly
all displays, so it's necessary to first check
that
the green channel
is
being cancelled
before using the filter.
First bring
up
the Color
and
Tint
pattern
and
look through the
IX
side
of
the filter.
Look at the left side
of
the screen. Through the filter, the interior
of
the three bars
should look black, just like the background.
You
may still be able to see the edges
of
the bars faintly, which
is
perfectly fine.
If
any
of
the bars
is
at all brighter
than
the black space around them, then switch to the
2X
side
of
the filter.
If
any bars
are still brighter
than
the background,
then
you'll need to fold the filter
in
half
to make a
3X
filter. The
3X
filter
is
nearly opaque,
and
to use it you may need to
make the
room
completely dark
or
nearly so. This
is
the exception to the rule
about
calibrating in the same light you normally watch movies in; for this adjustment,
if
you need to make the room dark
or
wait for nighttime to make the filter work,
do so.
