    Hi, I’m having trouble making 3D Luts to use with madVR with my LG C2 OLED.
    What I want to achieve is two 3D Luts, one for SDR (Rec.709) and one for HDR (BT.2020).

    What I did was used the “Video 3D Lut for madVR (D65, Rec 709)” option in DisplayCal and I got a lut generated that I was able to
    put into the Rec.709 field in the Calibration Tab of madVR.

    Then, i did the same but chose the “Video 3D Lut for madVR HDR (D65, Rec 2020)” option and got another lut.

    The problem is that I am not able to put into the BT 2020 field in madvr…
    I get: “This 3DLUT file does not match the input/output format required by MadVR”.

    For some clarification, I do not want madvr to do any tone mapping. I just want a 3D Lut that would give me accurate colors when viewing
    HDR content.
    Furthermore, the TV auto detects the color gamut. That means that I am not able to make a BT 2020 lut in SDR because it’s limited to only Rec 709 colors.

    Could anybody advise me on what I should do?
