Hello,
I'm trying to calibrate and profile my display. In it's OSD panel there
are some presets "Standard", "sRGB", "AdobeRGB", etc. and also "Custom
Colors". In all modes except the "Custom Colors" Contrast and Brightness
settings are available only. In "Custom Colors" in addition to RGB Gain
and RGB Bias controls there are RGBCMY Hue/Saturation controls.
In dispcal utility there are options that help user to properly setup
RGB Gain and RGB Bias. But how should I act to setup RGBCMY
Hue/Saturation controls of the display properly?
Why do I think that it is important to setup RGBCMY Hue/Saturation
controls properly. I tried to calibrate and profile display in
"Standard" and "Custom Colors" presets and found the following. With the
default OSD settings gamut in "Custom Colors" is narrower than in
"Standard". But I would like to maximize the gamut that the display is
capable of. I raised up some of the RGBCMY Saturation controls in
"Custom Colors" and achieved wider gamut than in "Standard". But I did
it visually with the help of test images and it seems to be not very
accurate. Also setting up Hue visually seems to be not a good idea for
me, since I'm afraid I can deface colors. It would be nice to have
feature in dispcal that will help setting up RGBCMY Hue/Saturation
controls properly.
With best regards,
Ivan
