SVE SETTINGS
PURPOSE
LUMINANCE
Adjusts the overall image and screen background luminance. When the setting is too high to show, the
OSD characters are changed to yellow.
BLACK
Adjusts the black luminance. When the setting is too low to show, the OSD characters are changed to
yellow.
GAMMA
Allows you to manually select the brightness level of grayscale.
sRGB:
Gamma setting for sRGB.
L Star:
Gamma setting for the CIELAB color space Lab.
Rec.1886:
Gamma setting for HDTV broadcasting.
HDR-Hybrid Log:
Gamma setting for HDR, typically for UHD broadcasting. System gamma can be
adjusted.
SYSTEM GAMMA: System gamma is adjustable in 0.5-2.0 range. When “Auto”
is selected, the system gamma is automatically selected according to the
“Luminance” setting.
HDR-ST2084 (PQ):
Gamma setting for HDR, typically for UHD disk media and streaming videos.
Peak luminance value is adjustable.
PEAK LUMI.: Sets the peak luminance value to show HDR-ST2084 (PQ)
luminance range. A larger value will improve white saturation but the picture
become darker. When “Auto” is selected, “Luminance” is used as the peak
luminance setting.
DICOM:
DICOM GSDF (Grayscale Standard Display Function) is typically used for medical
imaging.
Programmable:
A programmable gamma curve can be loaded using optional NEC software.
Custom:
CUSTOM VALUE: The gamma value is selected from a range from 0.5 to 4.0 in
0.1 steps. For general images 2.2 is used. Increasing the value will make the
intermediate color darker, and lowering the value will make the intermediate color
brighter.

WHITE (K)
Adjusts the white by color temperature (K) or CIE x, y setting. A lower color temperature will result in a
reddish screen and a higher color temperature in a bluish screen. A larger x value will result in a reddish
screen, a larger y value changes the screen to greenish, and smaller x,y values will change the screen
to bluish white.
