Hi, there no way to fix that with CalMAN Home.
Use a calibration disk designed exclusively for CalMAN 5, because there is mismatch of RGB Triplets of calibration disk patterns vs. the ones CalMAN's engine expecting from the user to display. The most common error is to use AVSHD with CalMAN; while it's very useful disk for all to have to their collection, its having a mismatch for some grayscale patches, when you will use it to perform Grayscale calibration your gamma will be slight off to the mid/low-end range because AVSHD's Grayscale patterns are rounding fractional RGB codes down to the nearest integer. DVE disk is doing the exact same thing, so both are not 100% accurate to use for Grayscale calibration with CalMAN. (DVE don''t have any color gamut patterns also)
The difference you will have @ gamma calculations for:
5% Gray = -19.22% Luminance error
10% Gray = -9.23% Luminance error
15% Gray = -5.82% Luminance error
20% Gray = -4.10% Luminance error
25% Gray = 3.07% Luminance error
30% Gray = 2.39% Luminance error
35% Gray = 1.90 % Luminance error
40% Gray = 1.53 % Luminance error
You will not have these errors if you use a calibration disk that matches correctly the RGB triplet targets of CalMAN's Engine.
