6.2.2
Gamma/Colour/Crush
Native Colour Temp allows the user to select from pre-configured colour temperatures to match the
display. If this value is the same as the Colour Temp value in the (Input) Colour menu, no conversion is
performed.
Settings:
3200K, 3700K, 5500K, 6500K, 7500K, 9300K
Default :
6500K
6.2.2.1
Output Gamma
Output gamma allows to re-gamma video signals with pre-configured gamma values to match the
display. Input gamma and output gamma both default to 1.0. If they are both set to the same value,
there is no effect on the image.
If you need to reduce the level of certain color in the image, select a
higher value for the input colour Temp in the Colour menu, or a lower number for the Native Colour
Temp in the Output menu.
Settings:
1.0 to 3.0 in steps of 0.1
Default :
1.0
6.2.2.2
Black Crush
(LED models only)
This feature is available for models supporting LED walls. The input black level should be optimized
prior to using Black Crush and any filter settings should also be optimized first. Black Crush is not a
replacement for correct input settings, but it is available to clean up any remaining black level noise
on the signal which may be visible on very bright LED screens without reducing the peak white
brightness. This function is not the same as adjusting the overall black level.
It is recommended to use a setting between 0 and 16 and not more than 20. For most LED screens the
optimum setting for Black Crush is between 8 and 20. For particularly noisy subject material, 24 can be
used but detail loss may occur in dark areas. If too high a setting is chosen, image solarization may be
observed where dark image areas turn completely black or even change colour.
Settings:
0 to 255 in steps of 1
Default :
0
