I have it at 86 for Day and 82 for the Night. My max output on Day is 41+ and on Night is 34+. With the Contrast at 86 I am blowing out the 256 bar and on the Spears and Munsil GetGray ramp I do see a tinge of color in a couple of bars.
Can the Contrast setting affect the color that much? I'm just not sure where to turn with this.
Please if anyone has any suggestions please give them.
BTW I'm going to cross post this in the Calibration forum.
FYI the Color Setting is 46 in the Cal Night
Try using different gamma targets and maybe changing from warm 2 to warm 1 or neutral, for your day calibration.
If you are seeing any "tinge" of color in your gray step bars, then imo redo your gray-scale, or go back into what ever IRE is showing the "Tinge" and re-work that IRE, then recheck your full 10pt gray-scale along with your gamut.
Also make sure each of the 10pt IRE settings are stable.
I don't think your Contrast setting has much to do with your problem, but you may want to raise it for a day calibration.
You may want to try a step gray-scale pattern on the THX night or day settings to use as a visual reference, of-course that's saying there is no "Tinge" in that step pattern.
