+ | ===== BIAC6 Screen Configuration ===== | ||
+ | |||
+ | * 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. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | 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 | ||
+ | <code python> | ||
+ | |||
+ | import pyglet | ||
+ | |||
+ | display = pyglet.canvas.get_display() | ||
+ | screens = display.get_screens() | ||
+ | screenNum = 0 | ||
+ | #get resolution of screen 0 | ||
+ | win_res = [screens[screenNum].width, | ||
+ | |||
+ | #set the output to always go to screen 0 | ||
+ | win = visual.Window(size=win_res, | ||
+ | fullscr=True, | ||
+ | color=(0.2, 0.2, 0.2)) | ||
+ | |||
+ | msg1 = visual.TextStim(win, | ||
+ | msg1.draw() #draw it | ||
+ | win.flip() #put it on the screen | ||
+ | core.wait(5) #wait 5 seconds | ||
+ | win.close() #close it | ||
+ | core.quit() #stop | ||
+ | |||
+ | </ | ||
+ | |||
+ | matlab PTB the first screen would be #1 ( matlab is indexed starting at 1 instead of 0 ). | ||
+ | <code matlab> | ||
+ | |||
+ | %configure the first screen is psychtoolbox | ||
+ | screenNumber = 1; | ||
+ | [Window, | ||
+ | |||
+ | |||
+ | </ | ||
