+===== BIAC6 Screen Configuration =====
+  * BIAC6 is equipped with NordicNeuroLab ( NNL ) [[https://www.nordicneurolab.com/product/visualsystem-hd|VisualSystemHD]] goggles for stereoscopic display
+  * The individual eyes of the NNL headset are hard-wired to the graphics card on the display computer and not routed through the switcher
+  * because of this setup, the stimulus computer appears to have 4 monitors
+  * monitor 1,2 are connected to the switcher and can be switched around to all the different displays at the scanner suite
+  * 3,4 are directly connected to the googles and can only output there
+  * when configuring your tasks to display, please take account of which monitor you are sending the outputs since 3,4 will always be the googles only.
+  * the best way to control the monitor configuration on BIAC6 is with [[https://www.displayfusion.com/HelpGuide/WorkingWithDisplayFusionMonitorProfiles/|DisplayFusion]]
+  * there are several pre-configured profiles automatically loaded on BIAC6 to choose from:
+    * 1024x768, 1280x1024, 1920x1080 cloned displays ( on monitors 1,2 )
+    * 1920x1080 extended desktop ( across 1,2 )
+    * 1920x1080 cloned displays with the NNL goggles as individual display 3,4
+    * 1920x1080 extended ( across 1,2 ) with the NNL goggles as individual displays 3,4
+    * more default profiles can be added, but you can also configure and save your own profiles
+{{ :biac:experimentalcontrol:df2.png?600 |}}
+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.
+{{ :biac:experimentalcontrol:df4.png?400 |}}
+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.
+{{ :biac:experimentalcontrol:df3.png?600 |}}
+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.
+PTB:
+<code matlab>
+>> run SetupPsychtoolbox.m
+>> screens = Screen('Screens')
+ans =
+  % there is only a single screen
+  % you can use the first index, or min / max functions because there is only 1 option
+>> screens(1)
+ans =
+>> min(screens)
+ans =
+>> max(screens)
+ans =
+</code>
+PsychoPy:
+<code python>
+import pyglet
+display = pyglet.canvas.get_display()
+screens = display.get_screens()
+screens
+>>[Win32Screen(x=0, y=0, width=1920, height=1080)]
+ # screens[0] is the one and only screen
+</code>
+Any **EXTENDED** configuration, or configuration with goggles will result in multiple monitors being available.
+PTB:
+<code matlab>
+>> run SetupPsychtoolbox.m
+>> screens = Screen('Screens')
+ans =
+     1     2
+   %in this case
+   % 0 - the full extended display across the desktop
+   % 1 - screen #1 only
+   % 2 - screen #2 only
+   % because matlab is indexed a 1, you need to select the correct index to get to screen #1
+>> screens(2)
+ans =
+</code>
+PsychoPy:
+<code python>
+import pyglet
+display = pyglet.canvas.get_display()
+screens = display.get_screens()
+screens
+>>[Win32Screen(x=0, y=0, width=1920, height=1080), Win32Screen(x=1920, y=0, width=1920, height=1080)]
+ # screens[0] is the first screen
+ # screens[1] is the second screen because python is zero indexed
+</code>
+You need to code your tasks to send to the specific screen you want your subjects to see.  If they are viewing the projector, then they can only single a screen at a time.  The default is to send the first display to the projector.
+  * screen 0 in matlab **only** if its a **cloned** display, or screen 1 if it is extended/goggles
+  * screen 0 in PTB
+One of the best ways to account for a variable to setup in matlab would be to code the task to work with either.
+Matlab:
+<code matlab>
+screens=Screen('Screens');
+%if there is only 1 entry
+if (length(screens) == 1)
+    %use it
+    S.screenNumber = min(screens);
+%but if there are more, use #1 explicitely
+elseif (length(screens) > 1)
+    S.screenNumber = screens(2);
+    %same as S.screenNumber = 1;
+end
+[S.Window, S.screenRect]=Screen('OpenWindow',S.screenNumber, S.screenColor,[],[],2,[],[]);
