+ | * BIAC6 is equipped with NordicNeuroLab ( NNL ) [[https:// | ||
+ | * 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:// | ||
+ | * 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 | ||

+ | |||
+ | 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. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | A couple of the 1920x1080 profiles are accessible directly from most of the system' | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | 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, | ||
+ | |||
+ | 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(' | ||
+ | ans = | ||
+ | 0 | ||
+ | |||
+ | % 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 = | ||
+ | 0 | ||
+ | >> min(screens) | ||
+ | ans = | ||
+ | 0 | ||
+ | >> max(screens) | ||
+ | ans = | ||
+ | 0 | ||
+ | |||
+ | |||
+ | |||
+ | </ | ||
+ | |||
+ | PsychoPy: | ||
+ | <code python> | ||
+ | |||
+ | import pyglet | ||
+ | |||
+ | display = pyglet.canvas.get_display() | ||
+ | screens = display.get_screens() | ||
+ | screens | ||
+ | >> | ||
+ | |||
+ | # screens[0] is the one and only screen | ||
+ | |||
+ | </ | ||
+ | |||
+ | |||
+ | Any **EXTENDED** configuration, | ||
+ | |||
+ | PTB: | ||
+ | <code matlab> | ||
+ | |||
+ | >> run SetupPsychtoolbox.m | ||
+ | >> screens = Screen(' | ||
+ | ans = | ||
+ | | ||
+ | |||
+ | %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 = | ||
+ | 1 | ||
+ | |||
+ | |||
+ | </ | ||
+ | |||
+ | PsychoPy: | ||
+ | <code python> | ||
+ | |||
+ | import pyglet | ||
+ | |||
+ | display = pyglet.canvas.get_display() | ||
+ | screens = display.get_screens() | ||
+ | screens | ||
+ | >> | ||
+ | |||
+ | # screens[0] is the first screen | ||
+ | # screens[1] is the second screen because python is zero indexed | ||
+ | |||
+ | </ | ||
+ | |||
+ | 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/ | ||
+ | * screen 0 in PTB | ||
