Hi,  
  
I want to do some experiments with a PC (Windows XP SP2) which has a  
second screen connected to a Cambridge VSG 2/5 card. I initially  
thought I could use this screen with psychtoolbox by using the screen  
maximum number given by:  
  
Screen('Screens'))  
  
However, this command only returns 0, so it's not using the VSG  
screen. So my question is: Is there a way to display my stimuli on the  
VSG with pscyhtoolbox? Am I doing something wrong?  
  
  
Thanks a lot,  
  
Pablo Polosecki

Hi Pablo,  
  
I just programmed a visual search experiment with the VSG and you  
should program it with the CRS Toolbox for Matlab. There are a lot of  
good examples on how to program experiments.  
  
Hope that helps,  
  
Michael

The VSG isn't supported at all. It isn't an OpenGL  
compatible graphics card.
