REVIEW: NEC LCD3090WQXi-BK Part 13
Comparison of calibrated profile with AdobeRGB
No surprise then, when the monitor is compared with the AdobeRGB standard: deviations seem considerably smaller as compared with the sRGB standard. Here, the extended colour space is in its element. The white point and gamma value are optimal.
The average deltaE value is just 1.8; this is very good. Some larger deviations can be seen for red and magenta only, but these are unproblematic. The correction curve of the graphics card shows that the software practically does not have to intervene in the colour output. Here, too, the NEC 3090WQXi is equal to the Eizo SX3031W.
Representation of the RGB correction curve after calibration to the AdobeRGB standard. The closer the three coloured lines are to the 45° axis, the fewer colours had to be discarded for the correct calibration of the graphics cards and the more intact the colour gradients are.
We then calibrated the NEC LCD3090WQXi to the UGRA criteria (5800K, Gamma 1.8), in order to determine how suitable the monitor was for digital pre-printing processes/soft proofing. The model qualified for UGRA certification where the brightness is at least 150 cd/m². The model fails certification for grey balance.
The detailed UGRA report can be downloaded as a PDF file.
The programmable 12-Bit Lookup table on the NEC LCD3090WQXi is a condition which allows for hardware calibration to be carried out. As already mentioned in the introduction, this option is not available with the European version of the 30-inch model.
However, the model does come with a "self-calibration" feature. With the aid of an X-Rite i1 Display Colorimeter, the white point, brightness and gamma value can be calibrated. The relevant changes are then written directly "to the hardware". However, this process cannot replace a proper hardware calibration because no profile can be created.
