Craig,

Is there any kind of upgrade program for those of us that had just purchased a MOOME right before the 3D protocol??

Just an FYI.

Right now we are having a compatibility issue between the Moome EXT and the RadianceMINI. It seems there is noise on the HDMI signal when the two are combined. The RadianceXS and RadianceXE work fine with the Moome EXT. The RadianceMINI also works fine with everything else that has been tested.

I will keep you guys updated as we are hoping this will be solvable.

Can you try a hdfury3 and see if that has noise on it?

[quote="Alan Head"]I have spent a considerable amount of time experimenting 3D over the years with different shutter glasses. The following may be of interest :-

Setup :-

G90 CRT Projector with P19LUG tubes, HTPC based on ASUS P7P55D motherboard, Blackmagic Intensity Pro 1080i capture card. Radiance XE+ 3D Video processor.

Glasses :

Nvidia 3DVision
Edimensional wired via VGA dongle
Edimensional IR via VGA dongle
Samsung SSG 1000 modified to run from Edimensional VGA dongle.

Conclusions :

NVidia customer support non existent when you are using CRT technology despite their own spec saying system supports CRT monitors with high refresh rate capability. NVidia glasses look good from an aesthetic point of view but suffer from severe ghosting (on IIyama CRT monitor as well as G90)

Edimensional glasses work well with virtually no ghosting but image rather dark.

Samsung glasses offer best compromise, much more light coming through than Edimensional and virtually no ghosting.

I have improved the ghosting on Nvidia glasses by running a much higher vertical resolution than I need and then overscanning the picture to get it where I want on screen. This improves the ghosting at the expense of bandwidth. So the big problem with NVidia is a lack of sync adjustment for the glasses.

Other Info :

I have just bought the Radiance XE+ 3D and as it develops with full CRT 3D Support I hope to settle on one type of glasses. I suspect with the Radiance 3D, Sync will end up really good (Lumagen customer support is in a different league to NVidia) and I am sure P19LUG tubes will be fine. Watching Avatar in 3D via the Samsung Glasses the image is pretty impressive with decent 3D depth and no ghosting marring the experience. Once I have greyscale/colour calibrated the 3D input through whatever set of glasses I decide to go for I know it will look even better.

I look forward to the day my NVidia 3DVision kit can be removed from my system.

Alan,

do you use these Samsung glasses with the PC? Via the ED Dongle plus the 3d Vision emitter plugged in? Sothat you use the 3d vision software? Or is my understanding wrong, and you use them on a different path/system or the ED software to genrate 3D content. I also used old shutter glasses via their VGA dongle with the 3d vision emitter plugged in. This works with my 8800Ultra card from EVGA. Later generations did not provide a sync signal anymore. But as you wrote, these glasses are very dark. Please provide more details on these Samsung glasses.

Best regards from Munich

Whats all the fuss about glasses (redusing brightness etc..)
This guy has neat solution Wink

Is it possible that the projection tube is ghosting from lens or the halation of the electron beam?

Is anyone still using CRT projectors?

Any CRT use at all?

Are there any uses for CRT projection tubes or would anyone like info for CRT's?

If anyone needs help with CRT issues I am a CRT engineer and can offer some info.

I have been using the nVIDIA 3D shutter glasses for abit over a week now, and i get zero ghosting on my Runco DTV 991 at 72 or 75 Hz, and using my CRT monitor at any resolution itll do, there is no ghosting on that either. The monitor is an LG F700P.

Testing with 3D bluray movies has been abit light on, due to numerous bluray playing programs having an issue with nVIDIA and reseting the computer... I can occationally make them run a few minutes and the effect on the NEC is perfect, no ghosts.

My InFocus DLP on the other hand.... Ratsh**... Ghosts at any refresh in certain parts of the screen, and the picture is so weak on the 120 inch screen id say it must need a new bulb...

Im yet to try my Epson EMP-S5... Dont have much hope for it, but it is ALOT brighter than the InFocus...

Not sure why youre getting ghosts on the CRTs youre using, wonder if it has anything to do with your computer being up to the task?? Mine is reasonably powerful, but my video card is only a 9800GT, so its certainly nothing to rave about...

I should also add ive got the really old Sega-Scope 3D shutter glasses, and they are perfect too. They run at either 50 or 60 Hz depending on the region of the console ( or the position of the switch after you mod... ) and there is no flickering on my NEC PG...

CIR Engineering · Posted: Sat Apr 28, 2012 5:11 pm Post subject:

You will get less ghosting on lower refresh rates but more flicker. 72/75 Hz has a good bit of flicker and is not good for movies from 3D BD or 60Hz sources. The dimmer the image the less you will notice the flicker as well.

More ghosting occurs with higher refresh rates, but flicker is reduced. On the G90 the flicker/ghosting is about perfect at 96Hz. 96Hz is good for 3D BD, but not good for games or TV. TV and games requires 120Hz which has more ghosting, but no judder...

48Hz has no perceivable ghosting, but will induce seizures because the flicker is so bad.

It's always a toss up. Every projector has some ghosting, you just want to hide it the best you can Wink

It must be just me then, cause i cant see one bit of flicker at 72Hz or above!! Been a while since i used the Sega glasses, but i remember being VERY supprised at how there was no noticeable flicker on that either, on the NEC 9PG with a 125 inch screen
