Can you tell me just what you did? What I did was to use Custom, set
Brightness and Contrast, Color Controls for R, G, and B, and I chose one
of the 3 choices for Gamma. I don't remember the details, but I did
that while trying to follow the argyll instructions for
calibrating/profiling a monitor. I don't see anyway to just turn off
the `advanced display settings'. I don't remember the details of what I
did, but presumably much of it I need not have done.
