psychopy: visual.Window() initialised with stereo=True fails with exception "pyglet.window.NoSuchConfigException" - pyglet

Question

I am new to psychopy and I have written a small piece of code to display fixation point. Everything works fine, if I do not set the option "stereo=True" or "stereo=False"
But the moment I set "stereo=True", it fails with exception
"stereo=True fails with exception "pyglet.window.NoSuchConfigException"
What am I missing here? Any help would be very appreciated.
I need to use this to supports quad buffers.
Complete error:

Here is the sample code
from psychopy import visual, event
win = visual.Window([1920, 1080], screen=1, units='pix', fullscr=True, stereo=True)
fixation = visual.GratingStim(win=win, size=10, pos=[0,0], sf=0, units='pix')
while True:
fixation.draw()
win.update()
if len(event.getKeys()) >0:
break
event.clearEvents()
win.close()
