Thanks for sharing your experience sound awesome, Id be real interested to know what the Cypress kit is worth & which
Polarized Filters from Berezin you went with..

Are you sending 1080p@60Hz to each 9500 for 3D viewing or some other rez/timing & are you running the Moome V2 full-HD internal
cards..

Thanks..

The polarizing filters over the CRT lenses are 6" x 6", with 45/-45 degree polarization, and good glasses to match. See this page, about 2/3 of the way down:

http://www.berezin.com/3d/3dglasses.htm

I'm using a Harkness-Hall Spectral240 "silver" screen; a regular white screen won't work with polarized 3D setups. Yes, it "hot-spots." I'm using a large, flat screen with short-throw lenses. Using the "contrast modulation" boards helped this to a large degree, but if you put up a uniform white field- it's there. I don't consider it noticeable during regular use.

The Cypress boxes take the 3D frame-packed output from the blu-ray player at 24fps. You'll need a 1-in/2-out HDMI splitter to drive both 3D boxes. They output 1080p/60Hz to both projectors via Moome VIM-FullHD cards. Including the splitter, the pair of 3D boxes, and international shipping, figure around $550

During the conversion process, the frame rate is converted from 24 to 60Hz. What we need, but don't have, is a test disc with 3D-enabled to check for this. I have noticed rare and fleeting motion artifacts during scenes with high contrast and quick motion, probably because the left and right images are being reconstituted by independent processors, which may perform the file-to-video "pull-up" slightly differently.

Since my Oppo BDP-93 has two HDMI 1.4 outputs, I figured I'd skip the splitter- unfortunately, there's a slight delay through my audio processor that translated to one projector being 1 frame behind the other. I was better off using one port and a splitter for video, and the second port to the audio processor just for audio.


Thanks, Mark

Thanks for providing other interested forum members your passive 3D project Mark,

Just wondering How you went about mounting your polarized filters infront of your lenses, I was thinking of some type of stand similar to the ones shown on the link you provided making for easy removal for 2D viewing ..

I may just give this a try since the financial outlay after having much of the hardware isn't significant so not A huge financial risk for me if I dont like it ..
BTW I spoke to Chris Bailey and he said that there is A delay on these units & that you have the only one ..

My screen is A Stewarts Lux deluxe with G1 Studio Tek 130 surface which I noted on AVS screens for 3D thread that it scores 4 in the Polarization rating so hoping while no doubt A compromize will be acceptable for passive 3D as 2D is my prefered primary concern as far as pic quality..

Jase..

I built my own brackets for the polarizing filters that hinge out of the way for 2D viewing. Just a simple, home-made aluminum frame painted black. Berezin's stands are more professionally-done, but it looks like they're designed for a pair of single lens digital projectors.

I posted a couple pictures of the polarizers under "photo albums > mhalsan"

As far as screens go, I never tried polarized 3D on a white screen. While I was building the second 9500, I was also on the waiting list for Harkness' Spectral240 screen. The timing worked out just right and everything got put together about the same time. A white screen will provide better 2D picture performance, but I'm not sure how much of a 3D effect will remain, if the screen doesn't retain light polarization to a high degree.

Thanks, Mark

HI Craigr,

Need some of your advise. I manage to get 3D out of my G70 @ 720p120hz but find the picture abit soft.
Can I do 3D at 1080i/120hz or any other resolutions to make the picture sharper.

Thanks, BTW 3D on CRT rock.

Hi Craigr,

On G70 I have to set Contrast to 90 and brightness 80 to have a reasonable picture.

OK will try other resolutions.

Cheers

Is 720p@96hz better for eliminating ghosting on the bottom of the screen?
I do not think 3d is possible without a radiance.
I have tried adjustable rf glasses monstervision and I can move the blue band from the top of the image out of view but then the bototm of the screen the ghosting is bad. I have a feeling I need to alter timings and the radiance is the only thing that can do that.
I am running 1280x720p@120hz at the moment on a necxg1352lc.

Now I attach some image of the Radiance setup:

I cannot see 3D image.

Please: can anyone help me?

Thanks

the glasses sold on the forum here are from bit cauldron.
are they better then other glasses?
can ghosting be eliminated when using regular tubes (lcp09).
is the picture quality better then other active glasses?

those glasses are tempting but if someone gets the same results with glasses for 1/2 price......

Hello,

i have read a lot in this thread, thanks to all out there, but i'm not 100% sure what is missing in my setup.

Could you please take a look, my setup:

Barco Reality 909
Oppo BDP-93
Lumagen XS (without 3D installed)
new external Moome for 3D
Gen2 emitter with Glases

Do i just need the 3D Lumagen key ? Or also the Lumagen 3D CRT driver box?

thank you
ElTopo

[ElTopo]

Hello,

i have set my Lumagen (with 3D key now) to output resolution 720p@120Hz and go directly into the Ext Moome V3.

But i will not get any picture on my Barco when i start a 3D Blu-Ray

The menu is visible in 2D.

Anyone does have an input for me here ?

thanks
ElTopo

[ElTopo]

Oppo and Lumagen is set to 3D = Auto

May that be the problem?

Update: resetted PS3 for a test and it works

Anyone got some experience if Samsung SSG-3700CR work with the Gen2 emitter ?
