Hello, I save the stimulation and use the runner, and the screen turns black and “no signal” appears. If you put two stimuli in, you can’t see the first stimulus, and you can see the second one. Why is this happening?
Hi - do you mean the text “no signal” appears? this sounds like a hardware issue ?
We are going to need more context: is this locally or online ? what version of psychopy are you running? what operating system? what kinds of stimuli are you presenting?
