Hello ladies and gentlemen,
I’ve written a software using the psychopy library. In fact I’m running an experiment that plays video stimuli.
So I’m using visual.window and MovieStim3.
Each time I run the experiment the monitor’s brighness/gamma or whatever it is decreases. This affects the settings outside of psychopy as well - desktop gets darker too.
The effect is very subtile for each run, it just adds up, when running multiple times.
The output of my gammagrid stays the same, as well as the settings that are provided to my ATI grafic card configurator.
Rebooting the system corrects and resets the driver settings I guess, because after a reboot the brightness etc is fine again.
Anybody has experience with this problem?
Is there any way to prohibit psychopy to change brighnetss /gamma settings at all? I’m not really required to allways have a calibrated brightness. But the videos become unviewable after a while.
