Hi all!
I'm trying to calibrate my monitor (Samsung S22E391H), and already at
the step of finding white point I'm stuck with inconsistent readings
of SpyderX colorimeter. In particular, if I hang it as it's supposed
to be used, I get color temperature of 6233K from dispcal. But if I
turn it by 90°, the result is 6137K, and when turned diagonally it
shows 6066K. Here's the full dispcal's line for each case:
Upright:
Current Br 209.41, x 0.3167+, y 0.3342- VDT 6233K DE 2K 0.9 R+ G-- B+
Horizontal:
Current Br 207.46, x 0.3163+, y 0.3381- VDT 6137K DE 2K 3.8 R+ G-- B+
Diagonal:
Current Br 209.60, x 0.3202+, y 0.3369- VDT 6066K DE 2K 0.4 R+ G-- B+
I suppose the device should still be useful somehow. But given this
discrepancy, I'm not sure how I should e.g. manipulate my monitor RGB
max value controls to calibrate it to D65. When I do it naïvely,
simply hanging the instrument in upright position, the resulting white
differs drastically (for my human eyes) from corresponding result on
another monitor (AOC 2269WM, which has opposite polarization).
How do you cope with such problems? Do you simply ditch such a
colorimeter and get a better one? Or is there some (easy enough) way
of averaging the measurement results from different orientations of
the instrument to set the RGB controls, and then create the actual
profile?
Thanks,
Ruslan
