Add the line...
Screen('Preference', 'SkipSyncTests', 1);
...at the beginning of your script.
This will disable the 10 secs. perceptual test, shorten
the duration of some internal calibration and test routines
and it will make PTB try to continue if it detects some
VBL synchronization problems that would normally lead to
abortion of your script. It is still wise to read potential
warning messages that show up on the Matlab console window :)
-> Obviously you should test your whole setup at least
once (per session?) without this line to make sure that
everything works properly.
