REVIEW: BenQ G2411HD Part 10
Comparison of calibrated profile with sRGB standard
In order to give an impression of the actual deviations in colour-management software, we created suitable test patterns in Adobe Photoshop, equipped them with the sRGB profile and measured them. As a CMM, Adobe (ACE) was used, with the rendering intent "perceptive". Since the monitor also offers a high degree of accuracy with 99-percent coverage of the sRGB colour space, the calibration gave rise to a very good result. The white point, brightness and gamma are close to the target values. The contrast increases to a very good 991:1 and this almost achieves the manufacturer’s indication. The deltaE deviations remain almost completely at a low level. Hobby photographers will only be concerned about the viewing angles of the TN panel, which are too small, and the grey resolution.
Representation of the RGB correction curve of the graphics card after sRGB calibration. The closer the three coloured lines lie to the 45-degree axis, the fewer colours must be discarded by the graphics card for correct calibration and the more intact the colour gradients remain.
The colour settings only had to be corrected slightly in the OSD. We selected the following settings for calibration to the sRGB standard: Brightness: 38 %; Contrast: 50 %; Red: 99; Green and Blue: 100.
In order to test the monitor with regard to general requirements, we calibrated the 24-inch model to the UGRA settings (5800K, Gamma 1.8 and 120 cd/m²). The BenQ G2411HD narrowly misses out on the settings because individual grey gradients deviate somewhat too strongly (92,5%) from the strict UGRA criteria.
The detailed UGRA UDACT report for the software calibration can be downloaded as a PDF file.
However, the main attraction of a TN panel screen is certainly not the suitability of the screen for pre-printing processes. Considering this premise, the BenQ G2411HD delivers a good result overall for calibration: even in the factory settings, there are few visible deviations. Hobby photographers should be able to work with it as long as they reduce the brightness.
