i1 DisplayPro/Resolve obviously wrong results

[Joseph Moore]

I am attempting to calibrate a video monitor (not a desktop display) connected via a BMD Decklink through DaVinci Resolve.

But when I try to calibrate this display with DisplayCal through DaVinci Resolve (per the documentation), the measured “calibration” results for white point and brightness are very obviously wrong (it measures 30-ish cd/m2 when in reality closer to 500), and profiling fails outright with an error message at the very end.

For reference, when using Calibrite’s software to calibrate my desktop monitors, I get expected results, which seems to rule out a hardware problem with the instrument itself.

Any help sleuthing this out would be very much appreciated.

Note the error message at the end of profiling reads: Error – Mcv max – min 0.000000e+ 00 too small

Hello Joseph, Wich procedure you use to calibrate the monitor with resolve?

Did you follow the guide ?

3D LUT creation workflow for Resolve

Did you try once before the procedure without using the decklink?

Is ArgyllCMS upto date on your system?

I never had issues with i1 DisplayPro Plus and the decklink but I am using win10 or linux(Manjaro and Ubuntu LTS)
