OS Win10
PsychoPy version 2023.1.1
Hi everyone,
I am running an experiment from my 60Hz laptop to an external 360Hz monitor (although I only have the graphics processing power to run it at 120Hz). I have asked PsychoPy to run the experiment on the extended monitor at 120Hz but I keep getting an alert saying the stop times are too low for a 60Hz monitor. Does this mean that PsychoPy is not detecting the extended monitor refresh rate of 120Hz?
-and if so how can I fix it?
I’m also not sure what to make of the Stdout messages saying that the monitor specifications were not found as I have entered them in the Monitor Center and told the experiment to use them :-S
I’m quite new to these processes, any help is welcome! Thanks so much.
Here is the alert message:
