    A post with a question to those who also calibrate their PC monitors in HDR. I use madvr to calibrate TV and monitors via HCFR, no problems with it then. But when using madvr to create a 3D LUT in Displaycal (and apply from 3dlut dwm), the measurement shows some ridiculous coverage values, and the file itself creates an ultra contrasty yellow look. What the measurement result looks like i put in  attachments.

    Has anyone encountered this problem before?
    I have observer 1978 2′ (with 1931 still looks bad), 6500K, XYZ + matrix, testchart set to pre BT2020.

    The monitor is a QD-OLED G61SD. Latest version of madvr and CMS. 3D lut set to hardclip and relative color. And i use now Calibrite Display Plus HL.

    Likely that due to some misconfiguration on your side madVR is not sending HDR metadata to display so you are running MS Win SDR (sRGB) simulation on HDR signal
