Gamma Calibration

Hi All,

I am using a CRT monitor to display visual stimuli. The monitor was gamma-linearized and I have the color look up table (CLUT) in a csv file and/or an np.array of shape (255, 3). I don’t have access to a photometer or any other hardware that would let me do the calibration from within the monitor center in psychopy. Is there a way to use my stored CLUT? Greatly appreciate pointing me in the right direction. I had a look here and here but nothing stood out as the obvious solution to my problem.

Best Wishes,
Dan
