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”.
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.
