    Same image, no LUT.

    Attached is your image through the 3D LUT. Something (else) is messing with the picture in your case.

    any guesses?

    I ran a calibration with 115 patches and for some reason that LUT outputs a normal looking image. What could be the difference between the two calibration profiles that would cause this major change?

    Can you search for the *.cube file that you are using (“Resolve 2019-05-19 10-02 0.3127x 0.329y S XYZLUT+MTX.Rec709.B0.0,2.4Gawn65.cube”) in “C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT” and attach that? There has to be a difference between that file and the original.

    The archive you attached was the 115 patch version, but that shouldn’t matter. If that wasn’t the one you had problems with, please attach that instead. Probably misread(s) due to (too low) pattern delay would be my guess.

    I’m unable to attach the .cube files. Is there another way to send them?

    Create a ZIP.

    Yep, the second one (Resolve-7…) with max dE of 36 definitely is faulty (misreads). Absolute max would be 5 dE. First one (Resolve-6…) looks fine.

    I’ve attached ZIP files for both 3D LUT .cube files.

    Resolve 6 was profiled with 115 patches.

    Resolve 7 was profiled with the standard 1545 patches.

    How can I adjust my profile settings for Resolve 7 so I don’t get faulty misreads?

    What’s the make and model of the display you are using?

    That one seems to have a dynamic contrast feature, make sure it is disabled. Also make sure macOS night shift doesn’t kick in during measurements. Other than that, pattern delay of 1100ms seems to work fine in your case, that was the delay you used for the smaller profile. Maybe bump it up another 100ms just to be safe.

    I would also recommend profiling the monitor in its native gamut mode.

    How do I know what is the native gamut?

    None of them apparently 🙂 What are the options under “Color Mode”?

    The same gamut options only selecting gamut from that menu disables user defining RGB values.

    I’ll try another 1545 profile at 1200ms.
