Toy Story 3 (3D) Polorized glasses

Thread Starter 
Just saw this movie yesterday in 3D using glasses from Real 3D or something like that (think they are polorized).

I thought this method/glasses was inferior for active shutter glasses (ASG) however the picture that I saw was very bright, looked 1080p to me and no GHOSTING.

If this method is superior then why did Samsung, Panasonic and Sony give us
ASG for our 3D tv's; all of the abobe mentioned tv's have ghosting issues with ASG.

I'm confused; should I wait for 3D TV's with polorized glasses. I think Vizio will be using this method.

Please comment.

You can't get Full HD per eye using a polarized display like an LCD, PDP, etc. They only work using half vertical resolution = 1920x540

As Lee said polarized is greatly inferior when not using a projector setup for 3D.

I love RealD at the theater when it's done right (Christie DLP, Z-Screen XL, 50ft wide screen, etc). I recently went to the AMC in Seattle and their Christie screen (number 3) had a ton of ghosting and the screen had vertical lines in it. Looks like I won't be going back to AMC/Regal since they either use Sony 4K or crappy Christie setups (unlike Rave which has flawless Christie setups).

My local theater is Sony 4K RealD and I usually notice a good bit of ghosting. What makes this particular implementation subpar? The projector filters? The screen?

It may be the implementation. The way they setup RealD on a Sony 4k projector is to add a twin lens sysetm:



As opposed to using a single lens system. Do you know what the frame rate is?

I don't know what the frame rate is, but I did peek into the booth the last time I was there and the setup looked much like the image you posted with the over/under polarizers.

Sony 4K is the split lens. It uses 24fps since there is no frame sequential (it's like IMAX Digital except with one projector).

The reason I don't like the Sony 4K is simply that I prefer the look of the DLP image over SXRD. The SXRD appeared to have worse contrast, brightness, and was more soft than the DLP.
