    Is this possible to do without any calibration instruments? All I want to do is fix the over-saturated colors on my HP zr30w in video games with the use of reshade and a 3d LUT file.

    I have installed displaycal, and loaded my .icm file, but even when I check “enable 3d lut tab” and check or uncheck “apply calibration” the “Create 3d LUT” button remains grayed out.  I have tried to load my .icm file (which was downloaded from HP’s website) but I get an error saying “The file does not contain settings”.

    Use the standalone 3D LUT maker and set the HP profile as destination. As source choose Rec. 709, tone curve gamma 2.2, rendering intent relative colorimetric, format ReShade.

    Thank you! I had not noticed the standalone 3d LUT maker in the Displaycal program folder. With that I was able to generate several files including colorlookuptable.png

    I installed reshade in my game directory, and the lut.fx shader, then

    1. deleted lut.png in reshadeshaders/textures
    2. copied colorlookuptable.png to reshade-shaders/textures and renamed it lut.png

    Then when I started the game reshade started and I pressed home to bring up the list of shaders there was a checkbox for lut.fx
    By checking or unchecking this box I could turn off the shader and see the difference in colors.  My colors are correct now!

    One note: I had to change my 3d lut size to 32×32 for it to work, 64×64 gave incorrect colors.

    ReShade’s own 3D LUT shader (lut.fx) is limited to 32x32x32. This limitation does not apply to DisplayCAL’s shader (ColorLookupTable.fx).
