The goggles have a polarizers on the front and back surfaces of each
goggle "lens".   Similarly, the LCD display have polarizers on the front
and back.  When the liquid crystal in each of these devices is in the
right state each will pass light, but in both cases that light is
polarized.  With a user seated in front of the LCD display with the
goggles on, what happens if the polarizers in the goggles are at right
angles to the ones in the LCD display?    (This wasn't an issue with CRT
displays since the light from those wasn't polarized.)

This was exactly the situation for goggles used with my ViewSonic VX922
display.  Stereo was impossible since I could only see the image on the
screen if my head was turned sideways (parallel to the floor). The
goggles don't even need to be on to see this, just hold them up in front
of the LCD screen and rotate them to see which direction will work.

Near as I can tell there is no standard for display polarizers.  I
checked a few displays and found vertical ones, horizontal ones, and
even one from Apple polarized at 45 degrees.
