Perhaps a silly question but I am trying to get my head around this.
I will be presenting images and using “norm” units seems to result in some distortion of the images.
I now want to give it a try with “height” units but I am not sure how to convert pixels to height units.
If of any help, my screen resolution is 1366 x 768 (which I believe it makes it a 16:9 aspect ratio) and each image is 286 x 397.
I had a look at Units for the window and stimuli — PsychoPy v2021.2 but didn’t help.
Thanks in advance.
