Hi Dear&nbsp;

  

I downloaded&nbsp;the&nbsp;psychtoolbox&nbsp;Version 3.0.15 on Matlab (R2017b), Windows and when I tried to compile the below script, I get the following errors:

  

PTB-INFO: Multi-display setup in explicit multi-display mode detected. Using the following mapping:

PTB-INFO: Screen 0 corresponds to the full Windows desktop area. Useful for stereo presentations in stereomode=4 ...

PTB-INFO: Screen 1 corresponds to the display area of the monitor with the Windows-internal name \\.\DISPLAY1 ...

PTB-INFO: Screen 2 corresponds to the display area of the monitor with the Windows-internal name \\.\DISPLAY2 ...

  

PTB-INFO: Enforcing script abortion and restoring desktop by executing Screen('CloseAll') now!

PTB-INFO: Please ignore the false error message (INTERNAL PSYCHTOOLBOX ERROR) caused by this...
&nbsp;

  

This is the scripot&nbsp;I try to compile:&nbsp;

  

if ~exist('window','var')

&nbsp; &nbsp;clear Screen; Screen('Preference', 'SkipSyncTests', 1);

&nbsp; &nbsp;Screen('Preference','SuppressAllWarnings',true);

&nbsp; &nbsp;window = Screen('OpenWindow',screenIndex,projValue\*[1 1 1]);

&nbsp; &nbsp;rect&nbsp; &nbsp;= Screen('Rect',window);

&nbsp; &nbsp;height = rect(4); width&nbsp; = rect(3);

end
  

  

  

Thank you very much in advance&nbsp;
