Best Passive 3d Projector and a couple of 3d related questions

Don't count out active shutter 3D untill you have seen it in a proper enviroment, not a BB show room. Any floresent lights flashing at 60hz will mess with the glasses. As far as I know no consumer passive 3D projector is on the market. You still need two projectors and a special silver screen that does not do well for 2D. RealD in theaters just has the active shutter on the projector instead of your glasses so it still is a flickering image. Find someone around you that has an active projector in a dark theater room and I think you will change your mind on a passive system. Although a passive system for $5000 is posible and can provide the best 3D there are other things to consider. As for a TV in a living room enviroment I agree passive is the way to go most of the time

Passive 3D for projectors is still new and not mainstream. Check this thread for starters:

Also, look up BlackShark in this forum. He has been an extremely knowledgeable and helpful poster on the topic of passive 3D projection.

There are none. Runco, DPI, and LG all have models but they are very expensive. Are many people interested in ~$5K passive projectors?

If you have to ask then you know its out of your price range.

If you are serious about it then DIY.
You'll need a 3D/demuxer to split to separate L and R HDMI feeds
Two projectors of the same type
Filters, either polarized or Dolby type

If you go with polarized then you need a silver screen (which tend to hotspot easily with 2D viewing) or if you go with a Dolby type then you need color correction hardware boxes

so at this point just settle for active until there is demand that pushes passive 3D projection down.

I use a Sony HW30ES with active glasses. Sure it is not perfect but if you are worried about the flickering... it's not an issue if you don't have lighting on around the screen in a darkened room. Sure I see it if I turn on my sconces and look at them or if I focus my attention to a small LED in my field of view, but the reality is flicker is not an issue in a darkened environment which is the environment the projector was designed with to begin with.

Little pricey, but converts to passive.

That's a neat little gizmo, that claims it can use theater glasses. Anyone here who has tried it out and willing to give some feedback?
