System: Windows 8 x64
Calibration hardware: i1Display Pro
Hardware calibration: Dell Calibration Software - 1.0.0, 1.0.1, 1.5.1
Software calibration: Argyll v1.6.2, dispcalGUI v1.5.3.1 (Spectral correction matrix)
Monitor: U2713H
I've been trying to calibrate and profile my system with the above mentioned setup. The question is, why am I not able to accurately set a D65 white point when using DCS for hardware calibration? Each of the Dell software versions result in a temperature mismatch of about (average) 100K every time. This results in a cold tint on my monitor. I've tried both pre-defined and custom calibration options in the software in three different color spaces (sRGB, aRGB and native). Values used are D65, 120 cd/m^2, 2.2 gamma. I've tried XML hack as well for 1.0.0, but 1.0.1 and (at least) 1.5.1 should include it as a default?
Here is a report of one of the aRGB runs from dispcalGUI:

Instead, software calibration done in dispcalGUI is more or less spot on. Here is a report for native color space:

Can someone shed some light on this issue? Is my calibration workflow flawed or is Dell's HW software just this inaccurate? The white point shift is clearly visible and quite unacceptable. Also, I am wondering why does dispcalGUI assume 6600K white point in the reports?
