    Hi. I’m very beginner in this area but trying to calibrate one display for color correction/grading reference.

    I’m using Xrite i1 colorimeter, monitor LG 32UD59 on Windows 10.

    I made a couple tests with fast measurements to train and learning a bit more of software and the whole process, and now i got stuck in white point issue.

    At my first test, with monitor reset to factory (and disabled all post process), my white point was looking orange/warm on eye, even though on RGB manual calibration on very beginning of process said it’s ok (3 RGB bars aligned).
    Setting was:
    Mode: LCD Generic
    Correction: LCD White LED family (AC,LG..)
    Whitepoint: As measured

    In the end of the process, my white point still extra warm.

    Then i made a few tests with “whitepoint manual color temperature”, takes a bit different result, but still very warm.

    At this point i tried to manually set my white point by eye the most pure white possible with monitor settings, but the RGB bars never align, even though i can see its clearly white (or closer to that, but, much better than factory default).

    So, on calibration settings tab, i tried “visual whitepoint editor” and reached the perfect calibration on RGB, but i dont know if it’s the correct path, looks like i tricked the process.
    In this last measurament, all set for slowest.

    My measuramente log point to “Measured vs. assumed target whitepoint”

    Any thought?

    It looks like 32UD59 is not sRGB but something P3-like. Hence it is not a White LED, it’s something else. Typically these multimedia P3 displays use WLED PFS phosphor backlights.
    Corrections are bundled with DisplayCAL for i1d3 colorimeter. Choose 95% P3 Panasonic VVX CCSS colorimeter correction as stating point if there is not user made CCSS in colorimeter corrections database.
