I’ve watched 200+ hours of 3D at home on several 3D
displays and video projectors using active shutter glasses, and
there’s *no* flicker. Sure, you can *make* the glasses flicker if
you don’t know that you’re supposed to switch off light sources
flickering at the frequency of the electrical system, like
fluorescent lamps. And as for passive polarized 3D, you will never
be totally rid of crosstalk. It’s unavoidable on polarization
systems, and crosstalk is easily the worst offender when it comes
to ruining 3D. Additionally, passive polarization TVs halve the
vertical resolution so you’ll get 1920×540 per eye, even from
Blu-ray 3D which is full 1920×1080 per eye on active 3D displays.
And while passive 3D video projectors, like the LG CF3D which is
essentially two video projectors in the chassis of one, can do full
1080 lines per eye, the requirements it places on the screen are
absolutely ridiculous. You’ll need a polarization-retaining silver
screen, usually a high power one with hotspotting, sparkling and a
narrow viewing angle, the installation of which has to be
absolutely perfect. If it isn’t, the 3D image gets riddled with
errors and becomes unwatchable. Passive polarized 3D, you say? No
thank you.
