You're basically saying nonsense, active and passive have their respective drawbacks and merits. Don't you think if passive was that good we would only find this technology by now and active would be dead ?

Wrong, the same horsepower is needed for both. You're not a 3D programmer are you ?

True, although not right for the last one (flashes) for ZScreen/RDZ technology at home or for passive in cinemas, they actually use single projectors with ZScreen-like technology.

Wrong. Independant tests have shown that active exhibits less ghosting than passive in cinemas (

Wrong, headaches are mostly related to the vergence-accommodation conflict or stereoscopic errors (divergence), which happens with any current stereoscopic technology.

That's plainly wrong, you still need to render two views of the same scene, be it for active or passive. And you forget to say that the field-interlaced format basically halves the resolution, making 1080p equivalent to 540p with all the jaggies, moiré and unreadble small texts problems.

Because for now it's the only way to have full HD S3D and low (with Plasma TV) to quasi non-existant ghosting (with DLP TV/projectors). For LCD displays, active and passive are quite equivalent for now, except for the much narrower angles of vision and reduced resolution with passive.
