*2 except PA231W.
Allows you to manually select the brightness level of grayscale. There are fi ve selections:
sRGB, L Star, DICOM* 3 , PROGRAMMABLE and CUSTOM. We recommend to show
grayscale image data on screen.
sRGB: GAMMA setting for sRGB.
L Star: GAMMA setting for eciRGB_v2*
3
DICOM* : DICOM GSDF (Grayscale Standard Display Function) is typically used for
medical imaging.
PROGRAMMABLE: The brightness of grayscale can be changed to your preference
by downloading the application software. You can select this when PICTURE MODE is
PROGRAMMABLE. This function could not select on Advanced OSD menu.
CUSTOM: CUSTOM VALUE can be adjusted when CUSTOM is selected as the GAMMA
SELECTION setting.
CUSTOM VALUE: The gamma value is selected from the rate of 0.5 to 4.0 by 0.1 steps.
Adjusts the black luminance. When the selected settings are too low to be displayed,
the indicator on the OSD will turn magenta.
Adjusts color gamut. When the selected settings are outside of the LCD gamut, the
indicator on the OSD will turn magenta.
people who have such defi ciencies will perceive colors. This preview is available in four
modes: Types P (Protanopia), D (Deutanopia) and T (Tritanopia) emulate color vision
dichromacy, and Grayscale can be used for evaluating contrast legibility.
NOTE: Depending on the vision of the user, including those with color vision defi ciency,
there will be a variation in how the screen's color is seen and experienced.
A simulation is used to illustrate the view of those with a color vision defi ciency. It is
not their actual view. The simulation is a reproduction of those with a strong color
vision mode of type P, type D or type T. People with a slight color vision defi ciency will
experience little to no difference compared to those with normal color vision.
