How to accurately map to a custom profile

[Vanessab]

Hi! I have been trying to map my external display to a custom profile that I created using the synthetic profile creator, however, whenever I run a verification profile on my display with the generated 3D Lut against my profile, I still get considerable error. Does anyone have any suggestions on what series of Argyll commands I can use to get an accurate 3D Lut? Any help is appreciated.

You need to :

1-create a LUT3D that maps synth profile (source) to destination (custom)
2-use an app to load LUT3D (DWMLUT in Windows)
3-set as default display profile synth profile in OS settings (it should clear VCGT, but do it anually if doubt)
4-verify in displaycal, using “settings: <<current>>” profile (in windows works, it will take default display profile) or in a clean instalation where settings is forced to be one of the custom profiles set simulation profile = synth profile + use simulation as display profile.

Thank you for your response! How do you complete step 1 in the process you shared? Do you have the procedure on how to map my measured data to a custom destination? I have been using Argyll command line arguments but I’m not sure what the best way would be to get the most accurate 3D LUT.

DisplayCAL-3DLUT-maker.exe, in DisplayCAL folder.
