    So this is the first time I’ve read the full self check report and when I compared it to the measurement report (extended verifation testchart, 81 patches) the results were very similar but I noticed that self check report  didn’t have “the blue jump” at zero prosent mark at the RGB Gray balance section, that I’ve always seen in the measured reports, including this one. Also, Correlated Color Temperature was very stable between 0-5 prosent readings in self check, again, unlike in the measurement report.

    In the past I’ve thought that the measurent report is inherentlymore reliable, so can you tell me what causes these (pretty minor) differences? If would choose a larger test chart (large or extra large verifation testchart) would I get maybe get better results in the 0-5 prosent areas?

    Most LCD displays have a blueish/purplish black point. You can correct for that with calibration (black point hue correction), but at the expense of contrast, so in 99% of cases you wouldn’t want to do that. The only relevant values are the delta E in the overview. You do not seem to have a visually colorized black.

    Florian, can you please explain what the difference it between the self check report and the measurement report. I get the measurement report, since you actually measure something, but I don’t quite get what the point of the self check report is and what it is “checking”. Maybe I missed it in the docs, but I’ve searched the forum and this is all I found.
