Hi!
I am also running Non-human primate electrophysiology experiments with ViewPixx(1920X1080@120Hz) with a Linux/X11 system. I want to mirror the display on the ViewPixx Monitor to another monitor (not the primary monitor- where I see the matlab window).
I tried the PsychImaging('AddTask', 'General', 'MirrorDisplayToSingleSplitWindow') as suggested above with an extended monitor configuration. But unfortunately , it only displays on one of the screens. Could you let me know if my X.org config file is set up in the right way to get this mirroring to work ? Thanks a lot!
The following is my xorg.conf file :
