REVIEW: Hyundai W220S Part 8
In order to gain an initial impression of the actual deviations in colour management software, we created suitable test patterns in Adobe Photoshop, provided them with the respective profile of the working colour space (sRGB, AdobeRGB, ECI-RGB) and carried out measurements. Adobe (ACE) was used as CMM.
Naturally, with the limitation to primary and secondary colours, we are unable to draw a truly detailed picture. Thus, for example, undercoverages may not even be noticeable if relevant hues which lie outside of the monitor’s colour space are not present in the image being viewed. Because of the relatively colourmetric rendering intent, colour compressions caused by the CMM do not arise.
Comparison of calibrated profile with sRGB standard
Since the monitor is not able to maintain its measured colours across a longer period, its deltaEs are noticeable even in direct comparison with the sRGB standard. However, the brightness and white point also deviate too much from the targets for a calibrate device.
Comparison of calibrated profile with AdobeRGB standard
We were also able to repeat this result for calibration to AdobeRGB standard: Despite low deviations in brightness and white point, the W220S is also unable to convince completely in this section.
Representation of the RGB correction of the graphics card after sRGB and AdobeRGB software calibration with 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 colour gradients remain.
The colour settings had to be corrected somewhat in the OSD. For calibration to the sRGB and Adobe RGB standard, we selected the following settings (because of the same targets): Contrast 80, Brightness 49, R=75, G=75, B=78.
