Hello,

I’m trying to calibrate an Imac Pro 2017, MAC OS High Sierra, Display Cal 3.5.2, Da Vinci Resolve 14.3, i1Display Pro

I follow all these steps: https://hub.displaycal.net/wiki/3d-lut-creation-workflow-for-resolve/

I’ve done this process many times on my Windows computers without any issues.

I get to the step where it has me adjust the Imac Display to get the RGB and brightness closest to center measurements. However, every time I adjust the controls in the imac settings  it reverts the changes back to the default. I only experience this problem when I’m going through the display-resolve process calibration. If I’m out of this program I can adjust it fine, but it will always default to the default profile when I start measuring! I can completely go through the process of creating the 3D LUT, but it just won’t let me calibrate it so my RGB and Brightness are at the center. Please advise!

Attached is screenshot of the step on Imac where I adjust white point and this is where the program keeps reverting back to default instantly no matter where I scroll the white point.

  1. The macOS calibration assistant changes the same underlying video card gamma tables as DisplayCAL, so both cannot be used together. In case the monitor doesn’t have actual hardware controls, you have to skip interactive adjustment.

    1. Hey Florian, thanks for help. So since I have to skip the adjustment, this will leave the calibration very off? There is no other possible solution to calibrate the iMac then with displaycal?

        1. Thanks Florian. So If I’m understanding this correctly I can completely disregard what its reading on the RGB and brightness and it will still calibrate correctly?
