Display Setup

@@ Line 81: / Line 81: @@
 ==== Other Potential Problems ====
 One thing I ran into (which may not be an issue with the input device used at the scanner), but my external keyboard had '''2''' entries when I ran the keyboard_info script. Moreover, when I tested both of those keyboard device IDs using the keyboard_info script, only ONE of them sent keystrokes. By chance, on one occasion, it was the device with the higher ID. However if there are multiple keyboards with the same name the experiment script might accidentally tune into the device that doesn't send any key strokes (this happened on one of my tests). When I unplugged/plugged in the keyboard and restarted MATLAB, new device IDs were assigned, and this time it worked okay. The moral of the story is to make sure that you have only one matching external keyboard, but if you don't (for some reason), to check that the entry with the smaller device ID gives you input when you run the keyboard_info script. If not, quit Matlab, unplug, plug in, and restart until the problem is resolved.
