I saw plenty of other types of 3D demos at CEDIA (the BD section hadn't been worked out yet, but I saw plenty of ways NOT to distribute 3D...)

lenticular stuck on the screen? i read a few stands with this sort or concept ? I noticed from what i have read HDMI 1.4 is needed for blu ray 3D standard so Sony and Panasonic seem to be saying.. so thats a new display and a new blu ray player for me ..err i'll stick 2 D for a while .

lg had a mad wii type remote and samsung had one with tv built in it so when you get a beer from the fridge you can transfer the tv picture to the remote..great gimmicks but total cack (brit slang for poo) when it comes to integration i bet.

Well the least ideal I saw was from JVC. They had a 1080p screen with a circular polarizing filter, which gave each eye 960x1080 resolution.

The problem was the demo was using the interlaced method of storing 3D content, which uses 1920x540 resolution. So they take the 1920x540 image, convert it to 960x1080, and the end result is less than tack sharp - 960x540 basically.

I believe the new 3DBD standard is supposed to deliver full 1920x1080 for each eye, which is of course what you'd want for either front projection for LCD shutter direct view.

I wonder who will be the first to release an inexpensive 2-in-1 3D polarized projector?

I wasn't at CES, but projector wise everything I saw at CEDIA was dual separate projectors for use with polarized glasses. Rather expensive.

They could always do one projector with LCD shutter glasses (since that's how Imax works), but I'm not aware of any work being done on that...

there was the LG at CES [Link: techradar.com]

but I think I would prefer polarized over shutter. I guess there is alwatys waiting for CES to see what else comes along

The problem with a polarized setup is cost - you need two projectors and a special screen designed to maintain the polarization (regular projection screen won't do, apparantly). LCD shutters lets you get away with a regular screen and a single projector.

I agree that polarized is the more "desirable" setup, but the LCD shutters is likely going to be mainstream, and the ones I saw actually looked fine with no flickering. And I'm the kind of guy that can take one look at a CRT monitor and tell you whether it's running 60hz, 75hz or 100hz. :-)

I also think shutter will be bigger for the home market (harder to do polarization for flat pannels). I never had issues with CRT, but I have issues with DLP, when I look at an image from a DLP projector (even with three pannels) I get a headache as if someone took a vice grip and stuck it in my eye sockets and tightening it. I am assuming it is due to the "flickering" on/off of the mirrors. That has me worried about shutter glasses.

The silver screen is good (not sure if it is critichal though) and I don't have any idea on price. But as for two projectors, the LG mentioned above will supposedly be 10k US$, and let's face it you can get a decent 1080p projector for under 1/3 of that, add that shutter glasses should be more expensive then polarized glasses and I don't think any solution will be cheap in the near future. But for polarization I hope that eventualy we get a, for lack of a better word, dual path projector (one light source, split in two, each go through a Red, blue, green LCD/LCoS, murged together and sent out one iris. Because with two projectors (light sources) each bulb will age diffferently so the projector would need more calibration.

i.e.
