REVIEW: Philips 220CW9FB Part 8
Comparison of factory setting with sRGB standard
In its factory settings, the Philips 220CW9FB only matches the sRGB profile to a limited extent. Although the colour values and white point are relatively well matched, the grey values and especially the gamma value are unconvincing. Unfortunately, the human eye is especially sensitive to grey values and therefore, this failing is clearly visible. A good average deltaE deviation of 3,9 cannot improve the overall impression.
Comparison of Image Display mode with sRGB standard
As well as the image modes Office Work, Entertainment and the Economy mode, we also tested the Image Display mode in particular with regard to the deviation of the colour values. Here, the gamma, which has increased to 3,27, and the deviations in the grey values, which far exceed our diagram, stand out in particular. The average deltaE is 8,4. The Image Display image mode can only b described as unusable.
Comparison of calibrated profile with sRGB
After calibration to sRGB, the 220CW9FB delivers a stunning result: the white point, brightness and gamma are almost optimal whilst the contrast drops to a still good 818:1. The largest deltaE deviation is a respectable 1.2 and the average is 0,6. It doesn’t get any better than this.
It was necessary to correct the colour settings somewhat in the OSD. For calibration to the sRGB standard, we selected the following settings: brightness: 56 %; contrast: 50 %; Red: 83; Green: 84 and Blue: 86.
