When do you recommend to use the 10˙ FOV setting? Is it better for a 24" WCG display? (EIZO said it is but they examined a fullscreen white test pattern...) Can I use these XYZ.10 measurement values in other color management softwares? (I think they assumes XYZ.2 but I am not sure how it works...) By the way, I think you didn't really fixed the "Sample Read failed" bug or there is no solution. I used to receive this error during display calibration and I never noticed it during the characterization. The calibration was stable now but I received this familiar message during the characterization (once with both of my displays). I think it can be a problem with the instrument black self-calibration because I used DisplcalGUI and I let it to bypass the instrument self-calibration between the calibration and characterization. (And I chose the High quality calibration, so it took a lot of time...) May be you should examine the safe time for the ColorMunki self-calibration and periodically ask for re-calibrations. (But this is not the best solution with display which has bad screen uniformity.) Or consider to disable the bypass option and/or the HQ mode for this instrument. Or there is another problem somewhere...
