Tint
(SHORT CUT:
from presentation level.)
Adjusts color hue to obtain true color reproduction of NTSC video signals. Use
or until the you reach optimum balance of red-to-green in your image. It is
best to adjust tint while displaying a proper test pattern — otherwise, it is
recommended that tint remain at its default setting.
Detail
(
SHORT CUT:
from presentation level.)
Adjusts the sharpness of the video image. Use or until the display is as
sharp as possible, keeping in mind that any level of detail above 50% will
increase the level of detail as well as introduce some level of noise in the image.
Set below 50% to filter the signal and remove noise from a noisy source. Keep at
50% to apply no detail.
Color Temperature
Applies either a preset color temperature (3200, 5400, 5800,
6100, 6500, 9300) or a Custom or Interpolated color
temperature to the image. All are measured in degrees
Kelvin and represent the "coloration" (reddish or bluish) of
the whites displayed by the projector — the lower the
temperature, the more reddish the whites, the higher the
temperature, the more bluish the whites. Use the following
as a guide for most applications:
Color Temperature (K) Typical Application
3200 theatre
5400 film and film-to-video transfers
5800 film and film-to-video transfers
6100 film and film-to-video transfers
6500 most video and computers
9300 some computers with a bluish setting
INTERPOLATED COLOR TEMPERATURE
- In specialized applications, such as
when you are matching adjacent displays with numerous sources, you may find
that you need a specific color temperature that lies somewhere between one
preset color temperature and another. In this case, select the Interpolated option
and use the slidebar to adjust the temperature as desired in increments of 10°K.
This new temperature, which is interpolated from the neighboring presets, can be
used with any source and appears as shown when it is in effect:
CUSTOM COLOR TEMPERATURE
- If you need a specific color temperature for
the current source only, select the Custom option. This will produce a separate
