Problems chaning from time to frame

OS (e.g. Win10): Win 10
PsychoPy version (e.g. 1.84.x): v3.1.1
Standard Standalone? (y/n) Yes
What are you trying to achieve?: I want to have my experiment to follow the refresh rate of my monitor which is 60hz.

What did you try to make it work?: I changed the stimuli in my trial from time to Nframe. I also changed all the parameters in each stimulus from “constant” to “set every frame”.

What specifically went wrong when you tried that?: Only the 1st stimulus in the trial appears. The rest do not.

Here are some screenshots. I included the csv file that I have for my loop. Not sure if that is a cause for the problem or not.

@ndelasoul, the problem looks like the type of duration you are using. In the first image, you are presenting an image at frame 120, but finishing the image at frame 2, so the frame finishes before it has started. Try setting your stop time as duration (frames) to have your image presented for a duration of 2 frames from frame 120 (start).
