User Guide
¹ Software controls the blue light emission by reducing excessive blue light, resulting in a more
yellow tone.
Color gamut describes the availability of colors in the display. Various standards were developed
2
for specific purposes. 100% corresponds to the full color space as defined in the standard.
NTSC stands for National Television Standards Committee, which developed a color space for
3
the television system that is used in the United States.
Remark
sRGB is a standard red, green, and blue color space that is in use on monitors, printers, and the
4
World Wide Web.
DCI-P3, short for Digital Cinema Initiatives - Protocol 3, is a color space used in digital cinema
5
that encompasses a wider range of colors than the standard RGB color space.
6
Adobe RGB is a color space created by Adobe Systems that encompasses a broader range of
colors than the standard RGB color model, particularly in the cyans and greens.
