The configuration changes a little. We still have an NVIDIA card but from the previous generation from what we installed on our test PC. The same goes for the OS as it’s still Windows but this time XP. The management of profiles changes and Vista was better conceived in this area. Here the procedure is longer (described in our other article) and a little more complicated. Moreover, nothing guaranteed the success of adjusting the monitor’s settings in this way.
Before pasting the profiles we verified color rendering on the screens with the four interfaces (2232BW DVI/VGA, VP930 DVI/VGA). It was identical to that measured on the test PC: a little too much blue on the 2232BW in DVI, in VGA it’s better, a VP930 with colors that are generally too reddish.
We copy/paste the files and follow the procedure described here and miraculously:

- average dE > 3: visible differences which can sometimes be problematic
- average dE < 3: good color fidelity and can be considered satisfactory.
- average dE < 2: excellent and good for touching up photos.
- average dE < 1: we can safely say that the human eye won’t detect the slight differences.
Color differences are reduced to around 1 and in the four test cases this value is much better than before installation of the profiles. All color dominances have indeed disappeared.
Personalized calibration with your own sensor and computer has an even better result, but this is already very good.
