I hope to explain fine what I want. Every time that I change or add a new pc, is a pain for me to adjust the settings if the new graphic card - always Nvidia ! - to reproduce my optimal colors combination. The goal is not to copy the settings from the old pc to the new: graphic card is different, monitor is new.... So, but I think that it doesn't exist, I look for a program that can capture the exact gradations of brightness, contrast etc of a my champion image in the old pc and compare with the gradations of the same image in the new pc. May be that it's a crazy idea....
