sorry for asking newbie questions continuously. I now managed to run a full 1D Dolby Vision Autocal on my C8. It seems, pattern insertion interferes with prolonged measurements my i1Display performs in the near black range. I turned pattern insertion off and voilá, Autocal did its work. I know, the panel drifts due to excessive heating so I‘d better find a way with pattern insertion turned on, but did not succeed so far.
Another question is about the correct settings for the LG HDR workflow. As far as I understand, one would calibrate DV against Gamma 2.2 and then let the TV do the HDR work based on the file CalMan generates and uploads, which itself represents the specific capabilities of the set under calibration. So, are my Workflow settings correct, see attached screenshot? What about the target colorspace? What would change, if I would do HDR10?
BTW, I had to replace each , with . inside the text file before uploading to the TV in order to get valid reading, otherwhise the set would turn pink in Dolby Vision mode. Maybe thats because I‘m resident in Germany/Europe.
The workflow is configured correctly if you change any of the calibration targets you will cause major issues and not get an accurate calibration.
We are working with LG on the pattern insertion flickering problem in Dolby Vision mode.
Calibrating HDR10 on the 2018 LGs Calibrates both HDR10 and HLG at the same time. This is because we are calibrating the panel Gamma and the only difference between those formats is the tone map.
