Cannot run the experiment because of window size issue

Hello, experts in psychopy!

I have a question for running experiment.

When I use psycopy in my window10 notebook, it makes some error in monitor setting.

10.0714 WARNING We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use [‘sounddevice’, ‘PTB’, ‘pyo’, ‘pygame’] (in that order).
11.8622 WARNING Monitor specification not found. Creating a temporary one…
11.8830 WARNING User requested fullscreen with size [800 600], but screen is actually [1707, 1067]. Using actual size

I want to find how to make my screen size automatically!

Can you give me some hint?

Thanks a lot!

That warning shouldn’t be stopping your experiment. Are you getting any other error messages? At what point is the experiment failing?
