Causes judders due to half the frame rate...I never have judder.
Causes nausea...in some people.
Causes screen image to be darker.....Adjusting tv settings makes this a non factor.
Glasses cost far too much...$50 is too much?
Have to charge batteries...Or replace them just like remotes.
Cannot fully lay on the couch (sofa) and watch active 3D (glasses must remain horizontal for 3D effect)...People lay sideways and watch movies? I'd say most kick back.
Yeah, I know the bullets are marginal at best. My point, both technologies have their issues. I'm still not fully sold on 3D. All I know is what I've seen. I've seen active, passive and glasses free 3D. Passive did not make me sick, the other two did. When watching passive on a 55" from 8', at no point did I think the video was soft. To me, active has more disadvantages than passive. Bottom-line, in a few years both will be a discontinued technology. On a side note, LG released info on their nano TV today. This passive TV will be the best HDTV of 2011. Mark my words. I will own this TV.
