One monitors with dual separate stimuli

Programming Help
1

I am wondering whether it is possible to create two windows(using Screen OpenWindow) displaying two different stimuli, respectively.

I have tried to Create two windows, etc.
W1= Screen(‘OpenWindow’);
W2= Screen(‘OpenWindow’);
Disp Pic(w1)
Disp Pic(w2)(it’s just abbreviate)
Screen(‘Filp’,w1);
Screen(‘Filp’,w2);

but the Window w2 has nothing on the Screen, is something wrong with my code or it is just impossible to achieve this in PTB?

It appears more likely that you would like to display both stimuli in the same window since you want them to be on the same screen. Have you tried that approach, drawing both to the same screen and then flipping that one screen?
