Eyelink Calibration on stereo display

Dear all,

I am trying to get an eyelink calibrated using a polarised display for stereo presentation (i.e. stereo mode = 1). At this point, the calibration routines in the eyelink toolbox do not seem to support displaying the targets in stereo (so to the two stereo buffers). Is there a simple way to change this, other than having to change the code itself and drawing the target to both stereo buffers rather than just the one?

I have contemplated using PsychImaging and MirrorDisplayTo2ndOutputHead as advised by one of my colleagues, but I'm only using a single screen.

Thanks,
Arthur
