Image ugly distorsion

Builder
1

Hello!
I have a png
green_1

But when I put it in the builder, I have this:
25 AM

I understand that it is smaller because I put at size : (0.2, 0.2)

So it should be a square ? It looks like it has distorsion

Thanks!

Hi,

Your image is distorted because your screen is not square. :slight_smile:

You’re probably using PsychoPy’s normalised (‘norm’) units. (You can look up the different types of units here: http://www.psychopy.org/general/units.html) As a result, PsychoPy scales the stimulus according to the width and height for your screen. You might want to use pix, cm, or deg instead (the latter two require a correct setup of the monitor in the Monitor Centre).
