I’m trying to display fullscreen images on a second monitor (projector) using the attached code (modified from the psychopy.org coder tutorial). Works fine when fullscr=‘False’ but only shows gray when fullscr=‘True’. Last posting I saw on this said it was a known problem Multiple Displays on OS X. Is there a fix? Is there a workaround?
Thanks for any info and sorry in advance for any noob transgressions.

from psychopy import visual, core # import some libraries from PsychoPy
#create a window
mywin = visual.Window([1024,768], screen=1, fullscr=‘True’, monitor=“testMonitor”, units=“deg”)
#create some stimuli
grating = visual.GratingStim(win=mywin, mask=“circle”, size=3, pos=[0,0], sf=3)
fixation = visual.GratingStim(win=mywin, size=0.5, pos=[0,0], sf=0, rgb=-1)
#draw the stimuli and update the window
#pause, so you get a chance to see it!
