*3 MDview 232 uses "DICOM SIM.", a value near DICOM gamma.
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 for Lab color space.
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.
This function electronically compensates for the slight variations in the white uniformity
level as well as for deviations in color that may occur throughout the display area of
the screen. These variations are characteristic of LCD panel technology. This function
improves the color and evens out the luminance uniformity of the display.
NOTE: Using the UNIFORMITY feature does reduce the overall peak luminance of the
display. If greater luminance is desired over the uniform performance of the display,
then UNIFORMITY should be turned off. A higher number produces a better effect, but
may also reduce CONTRAST RATIO. When BRIGHTNESS is shown in magenta, the
UNIFORMITY setting is automatically changed.
