Reference monitor calibration help

[Hunter]

I’m new to calibrating monitors through resolve and I’m struggling to find the correct way to calibrate my refence monitor. everything I’ve tried ends up being blown out highlights, and weird colors.

Specs:
monitor – ProArt PA32UCDM QD OLED set to native with gamma 2.4. power saving mode off, input range – full, color temp 6500.
Hardware – Decklink mini monitor 4k for clean feed, using Display pro HL from Calibrite, everything is using the latest firmware and drivers, and I have displayCal3 (the newer forked version from github).

I’ve also downloaded the CCSS file – ASUSTek COMPUTER INC PA32UCDM Native (i1 Pro 2).ccss and its doing weird things, I’ve tried calibrating with and without this correction and I get better results without it. I’ve attached photos of all my settings i’ve been using without the correction, the only thing that changes when applying the correction is the mode switches to “refresh (generic)”.

I’ve tried messing with several setting to get a the get a good LUT for DaVinci but i haven’t found any that worked. Has anyone calibrated this monitor in resole before? Is there something I’m missing? I really appreciate any help.
I’m grading only for online content. and I don’t have any color adjustments on in resolve when running the calibration.

Correction mostly corrects whitepoint,so if you get something else vs expected (whatever it be), you did something wrong.
Also IDNK what you mean with better results or weird things. Details needed.

One last thing, if things don’t go as expected on first try with that Resolve workflow, instead of wasting time, unplug it from decklink. Calibrate it as a regular monitor attached to your regular GPU (= no decklink), with Windows Desktop and all those things and validate if resulting native gamut profile+ grey calibration matches display, check white point, check grayscale and such. Once this goes OK, you may try to find which stage on “resolve LUT3d-> resolve out->decklink->monitor” is behaving in a bad way.

thanks for the fast reply!
By weird things I’m mostly referring to the blown out highlights, also the screen gets really dim. I can post upload my profile results and a screenshot if that helps at all. Again, i’m new to this so i’m a fish out of water when it comes to advanced calibration and understanding some of the metrics.

I will calibrate through my GPU and report back.

You are on Windows 11?  Displaycal 3.8.9.3 is the old version but it works stable on Windows 10 and Windows 11.   The new version was for PY support for Macs.

This is totally unrelated to colorimeter correction.

More likely to have activated HDR in windows while calibrating SDR (you should not) because SDR is the only thing you can calibrate (= calibrate grayscale, then profile to see how that display bahaves and store all info in an ICC/ICM file).

HDR modes send to display HDR signal (usually rec2020 pq, so all it’s encoded that way) and inside display firmware translates RGB numbers in Rec2020 PQ to whatever your display is able to show (P3 from X nits black to Y nits with fullRGB colors or Z not including W pixel in WOLEDS) using another set of RGB numbers sent to display panel. This cannot be fully corrected by a 1D lut (=grayscale) and most vendors do not provide an API to override its default  HDR calibration.
For HDR your best chance may be DWMLUT.
