True and false. While half the pixels of the source image
are never seen, it is not because the are black, but because only half are sampled
They are not "black" for the next 1/120th of a second because they don't exist
in that 1/120th of a second (and the shutters are closed in the glasses for the same period). However, due to the nature of the checkerboard pattern, there is information from all 1080 lines shown to each eye, unlike passive, where every other line is completely blocked by polarization and used for the opposite eye.
