Full screen resolution does not match the resolution in computer settings/wrong stimuli size

Hello @TParsons, thank you so much for such a quick response!

(I have just created a new monitor and tested it again)
In the Stdout window it says:
1144.4376 INFO Loaded monitor calibration from [‘2020_05_07 17:04’]

Here are the monitor settings:

and here is the piece of code where the window size is specified (it still has a lower resolution):

Best, Elena
