I'm attempting to calibrate another CG247X display on a different machine now and I've run in some issues I can't fix on my own. It's been a couple of months since I've done the last calibration, however I'm following the same steps here and something strange is happening when running a 21^3 Cube profile on the display. Despite successfully reading over 10,000 patches (21^3 + drift compensation) I can only see a similar amount of points in the profile as the basic grey ramp, primary, secondary +, both in the profile and in the later created LUT from these images. I tried both using Resolve and Eizo built-in as TPG, with similar results.
After LUT upload to the display, the results of post-cal seem to be identical to pre-cal, but I assume this is connected to the above.
Attached my are Profiling settings, both 21^3 profiles created (one Resolve, one Eizo), respective profile-to-rec709 LUTs & screenshot of post-cal verification.
