I’m using PsychoPy 1.90 so I’ll try the glfw backend.
For now, I have managed a work around, where I mirrored the two displays and set the Display profile to ViewPixx. This is not ideal because the experiment running on the second screen is quite distracting, but for now it has worked in applying the gamma correction from psychopy monitor centre to the ViewPixx display. However, the colours do not look correct, so I’m unsure if it has corrected properly. How do I check if the luminance values are linearised correctly? When I click plot gamma, I receive the following error:
Traceback (most recent call last): File "/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/monitors/MonitorCenter.py", line 1019, in plotGamma if lumsPre != None: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
I also can’t find any information about uploading the gamma table to the ViewPixx screen itself. All of the search results seem to involve psychtoolbox.
