The monitor is one year old and is a NEC Multisync 97F 19 inch, which was calibrated using Pantone/Colorvision Spyder. The problem is not with the monitor or hardware at all. GG1.8 inherently gives more detail in the lower Zones than GG2.2. That is a given. That is one reason Zone V in GG1.8 is higher than in GG2.2 and that is what allows the detail to be more visible in the lower Zones. This is on a 21 step grayscale strip. Now I'm trying to create a curve for paper,ink combination in QTR. I think that is going to be a good learning experience (if I don't pull out my hair).
