Latest 2 or..3 days? and a bit more, I lost track of time I worked on something new, that among other things allows full-resolution measurements.
I never saw that before but I really wanted that for years so.. I did it 🙂
256 values per graph for grayscale.. can't do more accurate on a 24bit display!
This is a very good step towards a full calibration suite for mobile. I'll explain more about it later.
