I’m trying to calibrate an imac 2011 with Displaycal ( insane soft btw good job ) and a colormunki x-rite.
The calibration and profiling went well and a good profile has been created.
There is the problem.
I’ve run the Interactive Display Adjustment to test the new profile. It’s alright but the new profile doesn’t stay on. The white point is correct for few seconds then shift to the original white point.
My RGB value are balanced for few seconds then shift to the original setting.
It’s not for professional use however I’m very curious to know what trickery is going on behind that screen.
