Hi guys, can you do a ranking of the glasses tested?
I'm curious to try it but I would not waste money.
Thanks

Hi Alan,

The boards I sent you appear to have cleared UK customs. Did you get them yet?

Hiya.
I just upgraded the graphics-card in my media pc and now i got a problem.

Seems like the vsync-pulse from this new card is not as clean as the old card.

Meaning any refresh over 80 hz confuses my controller for the 3d glasses.

What would be the easiest way to clean up the signal?

Also I am assuming that the projector itself does quite a bit of cleaning already so if
it is possible to get a clean vsync directly out of the projector then that would probably be a
better option. (Barco data 808s)

Hello to all,

With the great help of Craig (thank-you Sir Wink

) I finally got some time yesterday evening to fire-up 3D display on my G90 (driven with Oppo BDP-93 and Radiance XS (last FW 041011)+CRT 3D dongle+GEN2 IR).

First, as per Craig's recommandations here, I've setuped my own 1280x720p95.9 display mode with a 166.182617MHz pixelclock (~109.33KHz Hsync). I carefully tweaked this mode with H_Porches at lowest values (88/44/108 pixels) and V_Porches as high as possible (100/5/315 lines) to let the green phosphore having time to decrease and reduce ghosting. Like you Alan, I can just get the 16/9 screen filled with Vertical size (coarse and fine) at MAX values (without the G90 boards mod.).

I've been using SAMY 3D cartoon blu-ray to run my 3D tests.

Immediatly, I found that the Radiance failed to detect 3D 'fseq' mode ([AUTO] setting detect the BDP-93 source as SbS 3D mode Confused

). So I forced the 'frame sequential' 3D mode on the XS+ and got the correct image on screen Thumbs Up

. I've leaved the glasses delay time to 0.0ms because 3D looks very good with this default setting Shocked

I had to adjust the CRT 3D dongle HDMI bias to remove some sparkles on the displayed 3D image (G90's HDMI cable runs for 7m lenght).

I do have two pairs of 3D Glasses : One SSG2100AB (lithium bat) and one SSG2200AR (Li-ion rechargeable). The GEN2 IR emitter was set in orange led blinking mode (SAMSUNG) and I've got the SSG2100AB glasses working fine but failed to get the SSG2200AR to sync. Alan, did you tried these Samsung glasses and get them working with GEN2 ? I really don't understand why 2200 can't sync as 2100 does : they both share the same IR protocol Evil or Very Mad

Maybe the frame rate of 96Hz rather than 120Hz ?

I hadn't enough time last evening to carrefully adjust the G90 convergences in the corners of the image, neither MG focus (I should do this, for sure) but the image already looks very good with strong 3D effect.
[EDIT] Conv. and MG focus adjustments done : image looks superb now !

I just found that my 3m wide 16/9 screen looks quite dim through the glasses and been forced to rize the contrast to 80 (versus 70 in 2D mode). I've also noticed that some of the black levels get losted in 3D. I should redo the greyscale 'by eyes', through the glasses, for this 3D mode (is there's a 3D grayscale test pattern blu-ray available ? or should I use radiance test pattern ?).

This first couple of hours playing with 3D looks promising. I will continue the tests Thumbs Up

I'll keep you guys updated on my experiments Wink

John

P.S. does the BDP-93 '3D screen size' setup parameter does something on the displayed 3D image ?

Thanks for the infos Alan,

My 2100 glasses sync fine at 96Hz but not the 2200. I've contacted Michael about this issue and I'm awaiting for his answer, I'll let you know... In between, I may be able to try 720p120 3D mode (with small V_porches) on this 2200 glasses.

Alan,

Got Michael's reply today : he's puzzled about 2200 failing to work with his GEN2 too... he told me to either exchange/buy his dedicated samsung glasses SS1 new IR emitter or trade my SSG2200 pair to his SA3 Rolling Eyes

.

As per your comment, I'm gonna ask 3Dflightsim.com about SSG2200AR compatibility.

I have been toying with the idea of keeping my G70VR when/if it comes back from repair.

1. Is 3D for movies something worth doing on a CRT? How great is it when its working?
2. Am I likely to accrue any 3D advantages because I have the VR G70? I understand
the faster green tube is supposed to be a plus for 3D.
3. Can 3D be done predictably and affordably or is it mostly for hobbiest tweekers with plenty of time and money?

I would say the pricepoint I wouldn't want to go beyond is $300.
My favorite source is PC and thinking I would be well on my way there because I have a
Blu ray on that and Power DVD which is supposed to have 3D, my hope was maybe the
addition of an NVidea card with glasses might get me there.

I've only seen 3 3D films where it made a meaningful difference. Avatar, How to Train Your Dragon and Tangled.
And when it gets right down to it Avatar is still the only 3D yet offered a difference that was game changing.
For the time being I could live with being able to play just those. But I think I'll hold out on 3D til I either get a
large flat screen or less likely go to a digital PJ. One thing I noticed watching 3D on a Bravia is dimness was a non issue.

Huge Kudos to Craig for creating an environment where CRT'rs have a place to come make 3D happen.
I have long wanted to do 3D with my CRT projector. But I appreciate the logic in buying an affordable digital
just for that purpose.
