Hi, I’ve been having a number of issues while trying to calibrate my new LG 27BP95E-B (OLED) and can’t seem to get a decent calibration.
Hardware I’ve tried:
M1 Mac (osx 13.5.1) & Intel Mac (osx 12.6)
Davinci Resolve + Decklink 4K in PCIe Expansion Chassis
Colormunki Display, SpyderX Elite & Color Checker Display Pro
Argyll CMS 2.3.1, 3.0.0 & 3.0.2 (used most recently)
The main error I’m receiving is: Write file: 1, icmTextDescription write: utc-8 to ASCIIZ translate returned error ‘premture nul terminator, non-ASCII as it’s almost done profiling in Displaycal. As it doesn’t quite get to the step of finishing creating the 3D LUT I can use 3D LUT Maker to create the LUT using the .icc file, but sometimes see other errors in doing that.
The calibration I have run twice and most recently is using these settings:
Spectral correction: RGB OLED family
White level: 100cd/m
Tone curve: Rec. 1886
Calibration Speed: High
Profile Quality: High
Testchart: Very large testchart for LUT Profiles (4954 patches)
Create 3D LUT after profiling checked
Attached is a measurement report from my most current calibration. I used the Large verification testchart.
Please let me know if there is something I’m missing here.

Change profile name in profiling tab, you may need to delete “2 square” or other strange characters. Profile name uses parameters and should write on a label a profile name preview.
Use a very simple profile name just to test if this was the problem. Save current profile “param string” in a test file if you want to restore later.2023-11-10 at 23:35 #139665
That resolved my Write File error! Thank you.
As for another issue I’m having after the profiling is complete, I can’t seem to generate a measurement report. When I go to verification page, it gives me an IO error (see attached image).
Verification page settings are default:
-simulation profile (rec709)
-Use simulation profile as display profile – checked
-Rec1886 tone curve
-device link profile checked with the new profile.
I still have displaycal connected to resolve, so I’m not sure what sort of IO issue this could be.

Check file permissions for DisplayCAKL app on macOS security. It must be trying to acces the folder where you want to save HTML.
Note: it seems that Sonoma is not compatible with DisplayCAL (python2)
