That is helpful.
I don't seem to have much luck in choosing gamma I want. Can you
suggest a reasonable strategy for accomplishing that. The problem
seems, at least in part, due to the idiosyncrasies of my monitor, a
Samsung 226cw. I've tried working with the default settings and also
using the monitor controls, and neither approach seems to work very
well. It seems that if I get one thing right, something else is bound
to be wrong.
Also, it seems that dispcal -r may be giving me misleading information
about gamma. I believe we've discussed that before, but clearly it
didn't penetrate since I still don't understand it.
