REVIEW: NEC PA241W Part 14

"sRGB" (Luminance: 140 cd/m², Gamma: sRGB, White point: D65):
Brightness: 139 cd/m², Whitepoint: x=0.316, y=0.331, Metamerie: Off, Gamma: sRGB, Image mode: Full, ColorComp: 3

"AdobeRGB" (Luminance: 140 cd/m², Gamma: 2.2, White point: D65):
Brightness: 139 cd/m², Whitepoint: x=0.316, y=0.331, Metamerie: Off, Gamma: 2.2, Image mode: Full, ColorComp: 3

"ECI-RGB 2.0" (Luminance: 140 cd/m², Gamma: L*, White point: D50):
Brightness: 140 cd/m², Whitepoint: x=0.347, y=0.358, Metamerie: Off, Gamma: L*, Image mode: Full, ColorComp: 3l

Representation of the RGB correction curve of the graphics card after "sRGB", "AdobeRGB" and "ECI 2.0"-software calibration using iColor (left to right). The closer the three coloured lines lie to the 45° axis, the fewer colours must be discarded by the graphics card for correct calibration and the more intact the colour gradients therefore remain.

In order to gain an initial impression of the actual deviations in colour management software, we created relevant test patterns in Adobe Photoshop, provided them with the respective profile of the working colour space (sRGB, AdobeRGB, ECI-RGB 2.0) and carried out measurements. Adobe (ACE) was used as CMM. Because of the relatively colorimetric rendering intent, colour impressions are not caused by the CMM.

Comparison with the sRGB working colour space with regard to the monitor profile

Parameter	Target	Measured
White point / CCT Kelvin	D65 (6502)	6618
White point XYZ (normalised)	95.04 100.00 108.88	94.73 100.00 110.10
DeltaE from target white point	-	0,92
DeltaE from black body curve*	- (0,08)	0,52
Luminance / cd/m²	140	135,9
Black point / cd/m²	Native	0,21
Contrast / x:1	Native	647
Gradation / average	sRGB (~ Gamma 2.2)	~sRGB
