I am wondering if anyone might be able to provide me with help setting up a   
dual monitor setup on which I can present seperate image files on each   
monitor simultaneously. I have tried this with an extended desktop setup on a   
PC, but MATLAB v. 6.5 on Win98 with PsychToolbox did not recognize the   
extended desktop - neither as an extended/wide screen nor as 0 and 1   
screens. From a quick search, it seems this may be a common problem.  
  
I have been informed that MATLAB and PsychToolbox on a mac will allow for   
the recognition of two screens (0,1) that can be used to present seperate   
image files simultaneously. I am interested in pursuing this option. Before I   
purchase a dual monitor video card and/or new mac specific for this project, I   
would like to know if any of you have done this and, if so, if you have any   
hardware recommendations. Thank you. - Joe
