 If you do not use the NNL goggles, then it's probably in your interest to leave them disabled.

+The DisplayFusion monitor configuration is accessible from the Desktop icon, from the Start Menu, by Right clicking on the desktop, from the system panel at the bottom Right.
-Depending on your stimulus presentation software you may want to hard-code which display you are presenting your task.

-For instance PsychoPy the first screen would be #0
+A couple of the 1920x1080 profiles are accessible directly from most of the system's Apps by clicking the profile on the upper right hand corner.

+The "Reset Video" desktop icon will now just revert to 1920x1080 cloned displays, with the goggles disabled.
+Because of the variable nature of the display configuration, its best to login and select your preferred display profile, to always start the experiment session with a known configuration.
+A **CLONED** configuration with goggles off, will result in a single monitor to programs like PsychToolbox and PsychoPy.
