I also have a similar question.
I understand that psychopy.monitors is where to set specific monitor values, but I'm confused how to translate between Psychtoolbox's 'LoadNormalizedGammaTable' and pschopy.monitors.setGammaGrid.
In Psychtoolbox, you give it a whole set of values (255 values) [0 - 1] (consider this an x-value) and corrected gamma values where each value is a y value s.t. y = A*x^(1/gamma) (where you fit A and gamma from measurements).
In Psychopy.monitors.setGammaGrid, all this wants is min, max, and gamma. I don't see how this is equivalent. Could someone please explain?
