    Hello,

    I have a Spyder 5 calibrator and a Toshiba laptop with LP156WF4-SPJ1 display.  I don’t expect miracles from it but the blue colors are just way off! I am comparing it to two other calibrated displays that do not show almost any difference after the calibration.

    This is the settings that I am using to calibrate it:

    LP156WF4-SPJ1 #1 2017-10-07 13-29 D6500 2.2 S XYZLUT+MTX

    It took more than 6 hours to calibrate with the spyder 5. What am I doing wrong? What settings should I try? This is the third time that i have tried different speeds and settings but the blue colors are way off every time.

    I also made a verification and the Average ΔE*00 is 0.32 . There was only one row with 4.4 but I think that this was some sort of error.

    Hi,

    Other than the one outlier in the measurement report, I don’t see any indication of that.

    I am comparing it to two other calibrated displays that do not show almost any difference after the calibration.

    Colors are only supposed to match in color managed applications, and only colors that are actually in-gamut for both displays.

    It took more than 6 hours to calibrate with the spyder 5. What am I doing wrong? What settings should I try?

    The Spyders are very slow instruments. I would not recommend using slow calibration speed with them unless you are prepared to wait (also, the display may actually not be stable over such a long period of time, although enabling white level drift compensation may help some in such a case).

    I am comparing the images in Photoshop and the Working Spaces is set to Monitor RGB.

    If I have understand correctly, the measurement report says that my monitor is ok with reproducing correct blue color. Then how is this possible?

    A did the slow calibration just because of this problem. I will try the white level drift compensation next time I have to do a slow calibration.

    I am comparing the images in Photoshop and the Working Spaces is set to Monitor RGB.

    Monitor RGB is (almost) never the correct working space. If an image has no embedded profile and thus falls back to the working space, it basically means color management is disabled if the working space is monitor RGB. If images are coming from a (consumer) digital camera or phone, use sRGB as working space (and assign it to the images if necessary).

    A did the slow calibration just because of this problem.

    That won’tchange the color managed result. Calibration only affects non color managed applications (except whitepoint), and only whitepoint/grayscale and tone response curve.
