Thanks for the results John.

what is the advantage of shutterglasses vs polarized glasses.
i have tried 96hz at 1080p and it looked pretty cool.
i have seen 3d on a panasonic plasma television set and i wasn`t impressed.
the imax experience i had in the 80s was far better and that was of course with the 50cents glasses.

I also have a question. Now that my Barco 1209s is running and set-up properly with it producing a fantastic 'real life' quality picture from Blu-ray i want to get 3D. It would be great to have it on my Barco CRT but there are concerns with quality and cost. As Craigr and others here are 'experts' and innovators it is much easier for those to try and work with different options etc and may be more likely to afford it. Ghosting and glasses is the main concern at present. Glasses seems to be nearly finalised with the emitter options now well covered. As for ghosting it's still ongoing.

When i watched disney's 'Tangled' at the cinema in 3D i saw ghosting twice so it too is not perfect but it didn't ruin the experience. I can not recall seeing ghosting in any other movies at the cinema though, so i would not expect it to be perfect at home either but it would need to be pretty close.

In my case i want 3D. Question is should i get it on my Barco 1209s CRT or go digital. I love CRT for the obvious reasons and with Blu-ray it can be a magical experience. Just watching 'Avatar' is remarkable. The picture is that good!
3D is an unknown quantity though. Without seeing it first hand it will be an expensive investment but one i'm prepared for if the 3D quality is at least equal to 2D. The main costs will be getting a lumagen xs+ and some barco mods.

From the perspective of someone who knows and appreciates picture quality, watches 3D in the cinema, the digital options available (many cheaper than the crt route) and near future improvements (2k/4k, 48fps cinema film) what is the honest opinion of going down this 3d crt route at a cost of £3000 plus.

Hi Roy,

If you already own a Lumagen XS/XD/XE+ scaler to drive your Barco, the cost to upgrade your CRT to 3D is not that much money (CRT-3D dongle + IR transmitter + A pair of 3D shutter glasses is about $500).
If you have not such scaler today, you may go to digital but unfortunatly, most Hi-End 3D ready decent projector (like Sony VPL-VW90ES) will cost you more than £5000 and 2D picture is not as nice as 9" CRT !

Hi Craig,

sorry if this has been asked before:
besides needing 2x Radiance min/xs+ would there be an advantage running A stack for 3D using Shutter(Active) compared to just one projector ?..

Regarding screens for both polarized & Active formats I found this thread (FAQ and Discussion - Screens for 3D Projection) A good read over on AVS
http://www.avsforum.com/avs-vb/showthread.php?t=1300238

Jase..

I think you're right: lower refresh rate and hence higher resolutions is another advantage.

Ok - well - where are you going to find a processor that will buffer the 120Hz frames
and convert to simultaneous 60Hz projection. There is no real advantage to having
two projectors if they are forced to run at 120Hz with blackout frames.

Apologies to Craig for being A little off topic..

To allow dual projector/stack 3D setups 2 of these cheap Optoma BG-3DXL work as A muxer when set 1 for Left 1 for right for Passive..

From my understanding they will work with HDMI 1.3 and pass any rez upto 1080p 60Hz per box..

Abviously still need these http://the3dmarket.myshopify.com/products/linear-polarized-filters..

Jase...

I don't think $800 for 2 of them is cheap, but it's a start.
Why would a hdmi demuxer output 120Hz?
The reason that I choose for such a box is that my crt's can do 1080p@60.
I suppose the 120Hz input results in 2x60Hz output because it alters the l + r frames.
The only box I've found yet is the Cypress HDMI 1.4 3D demultiplexer with two HDMI 1.3 (1080p@60) outputs.
Unfortunately there is no reseller, maybe it's still not ready for production...

Andre,

Why just don't use rgbhv to split? The last few inches cable and à good splitter would be good enough for two displays

The Cypress CH-332 demultiplexer is available from an Australian company, link below. Chris is the contact there. My set shipped from Sydney on Thursday. Should be here next week. I've had polarized 3D with dual 9500s since last summer- and it's worth the work. Filters and glasses from Berezin, 3D driver from IZ3D (PC Games), but no 3D Blu-Ray support until now.

Thanks, Mark

UPDATE: I received the Cypress components. The set consists of an HDMI splitter, and a pair of converters, one for left, one for right. Setup took less than an hour; no HDMI problems, and the Oppo BDP-93 recognized the devices properly. Watched Coraline and Shrek Forever After; the system works just like it should. No ghosting, lightweight glasses, and a fairly bright, immersive 3D picture.

I realize that not many people are interested in doing 3D this way, but- it does work, and pretty well! Frankly, the hard work was done last year, setting up and matching two projectors. That took longer than I would have guessed.

Thanks, Mark

How does the Cypress box with glasses compare to your setup with filters?
Can I use my high gain Carada screen?
It would be great if I don't need a new screen
