Brightness should not be set to max, should be around 10 maybe. Black level should be 50.
Finally my AutoCal succeeded! And the 10-point offsets are within reasonable limits, not driven to maximes.
I did only 2 things:
1) Set all 3 tickmarks in CalMan to output PC levels
2) Did a manual 2-point calibration first to minimize dE at 20% and 80% luminances.
dE Formula I've kept at dE2000_JNDab, as per CalMan guide.
It is rather strange to have the Limited/Full scale video signal setting in 3 different places!
What seems to have had impact is the control #1
on the screenshots below.
can not be used, because when I set it to PC, I can not AutoCal grayscale multipoint any more - CalMan says "this feature is not supported on this device"
seems to have impact for internal pattern generator only (leaving it off did not change my results). I am still using Client3 to eliminate VM's virtual GPU from the equation.
PS, in SDR, I set my brightness to 5, then I get 120cd/m2 from IRE 235 patch.
EDIT: now I see, control #2 is only for target, not the generator. My bad...
EDIT2: Completely forgot - meanwhile I also had updated the BRAVIA firmware to the recent v6.6510 !!
