From what I could see, the calibration of the monitor is something similar, but not exactly that I was looking for, both in terms of result and due to the immediacy of the changes. Gamma Panel, in its simplicity, allows immediate intervention on those parameters (brightness, contrast and gamma) at hand in the Intel GUI which, with the new drivers, I have lost.
However, for the moment, the question on my behalf seems to be resolved. Thank you all for every suggestion and support.
