I feel like a newb with this.  Since I never really played with MiniLED.  I recently purchased an Acer Predator Trition 17X which comes with a DisplayHDR cert of 1000nit, the spec they advertise is that that it has full coverage of sRGB and DCI-P3; no other factory calibration like other manufactures.  I plan to do video editing with Resolve and some photo-editing on this laptop.

I currently own a i1Pro Spectro and a i1DisplayPro2/3 Colorimeter.  I am not sure what the workflow should be.  Do I first create a correction “ccss” file?

Yes. CCSS is portable and you can share it with community, CCMX is only for you.

 How can I verify colospace gamut coverage?  does DisplayCal also measure AdobeRGB coverage?  […]  I am using Windows 11 Pro.

Out of the box?

Set al calibration target to as measured (so DisplayCAL won’t correct), then create a profile, simple (matrix, primaries description) or 3dmesh (XYZLUT).
Resulting profile sumary will have typical colorspace coverages.

If you wish to verify out of teh box calibration, it’s easier and you can skip profile creation if you had used DisplayCAL on Widnows at least one time:
-change OSD mode to the one you want to verify
-Verification tab, simulate profile + use simulation profile as display profile, where simulation profile is what that OSD mode is meant to be (beware!!! Rec709 TRC is not what you want, same for Rec1886 on a low contrast display)
-Run measurement report.

As test chart you can use ISO_12646-2008_color_accuracy_and_gray_balance.ti1

For testing HDR you can use DisplayCAL cousin app HCFR

If someone can point me to a workflow document that would be great even what setting to choose/tick/check/uncheck…etc.
