I’m running the following program on macOS 10.14.3 Mojave from psychopy import core,visual,event def checkKeyboard(): for key in event.getKeys(): if key in ['q']: sys.exit() else: event.clearEvents() win = visual.Window([1024,768],monitor="monitor",rgb …

Thanks for the information. I edited my post following your guidelines.

My guess is that this is an issue with a retina display (is your mac a retina display?) In essence, we couldn’t decide the best way to handle reporting of resolution given that Apple took the policy of having these double-resolution monitors but “pretending” that their screen was regular resolution…

Thanks for the answer! My Mac has indeed a Retina display so the problem has to come from there. I could not find the code you mentioned in your answer to see if it solves the problem: Did I miss it? Thanks again!

Apologies: from psychopy import core,visual,event win = visual.Window([1024,768],monitor="monitor",rgb = [0,0,0],winType='pyglet',waitBlanking=True,units='pix', allowGUI=False,fullscr=False) myMouse = event.Mouse(visible=True,newPos=[0,0],win=win) msg = visual.TextStim(win, text='') msg.setAutoD…

Strangely, the code still does not work on my computer. The mouse and the message still appear in the upper left corner of the window with the message saying [1024, 768]. The coordinates which appear in the message seem correct. For instance, when I move the mouse manually to the center of the scre…

So, one thing that’s an FYI but doesn’t fix your problem: The way Python coordinates work, [0,0] is in the dead center of the window. So if you have a window that’s 1024x768, then [800,600] is actually way out of bounds to the top and right. The top-right corner of the window would have the coordina…

I still wonder if it’s worth going a different route with retina displays and providing everything in native pixel coords instead of this confusion with a (sometimes failed) attempt to use the silly virtual coords

I’m not opposed, but I’m not sure it’s entirely on PsychoPy’s end. This seems to be something about how Pyglet reports window size and the locations of certain things. Like, in this case, it’s not that PsychoPy is trying to work in one set of units and Pyglet in another, it seems to be that Pyglet i…

Experimenting a bit after reading your comments, I found out that the following program puts the mouse correctly at the center of the screen from psychopy import core,visual,event FULLSCREEN = True win = visual.Window([800,600],monitor="monitor",rgb = [0,0,0],winType='pyglet',waitBlanking=True,uni…
