Hello, I am running several 21 sony triniton crts and profiling with
S2pro. My RGB adjustments have 6 sliders, 3 for contrast and 3 for
brightness.  

I have always used the (RGB contrast) sliders only because they
represent the white point. But what about the blackpoint? I have to
set the blackpoint by eye, because on these old monitors the blacks
have a color cast that I can only remove with the sliders. 

Is there any provisions in S2pro for measuring the black point?

If not, why not?

Thanks!

Randy
