TMT5 plays 3d content flawlessly with this provided you preselect the 1080p24 FP mode manually first. PowerDVD10 doesn't seem to recognize that I have a 1.4 3d capable display. I installed the latest display drivers from Nvidia and the latest version of pdvd 10 ultra.

PDVD worked with the nvidia ready 120Hz optoma hd66 no problem....it just doesn't work with the new display.

Any ideas?
Which version of the nVidia software are you running? Are you connected directly or through a HDMI 1.4 AVR?

I am not using a 1.4 AVR. I actually have tried running both a 1.4 cable directly to the projector and the spdif for audio to my 1.3 AVR. I also have had the same success running with an old DVI-hdmi cable to the PJ and HDMI to the AVR for sound.

I am not sure which version of the drivers I am running (I will have to check tommorrow). I installed the latest version from the website and that was it.

I am wondering about ghosting though...I seem to be seeing more of it than some others have posted in the same scenes. I might try an ati card for the heck of it (and return it if its no better) or I might test against a dedicated bluray player.

Side by side video is going to ghost a lot with the new JVCs. I believe it's an artifact of the 60hz/eye frame rate and the inability of the D-ILA chips to refresh fast enough. 24fps 3D Blu-ray shouldn't ghost nearly as much. I doubt seriously that an ATI card will be any better.

I would tend to agree except that a couple of posters here seemed to have had this experience. Plus I am having a problem with nvidia and pdvd 10 (pdvd doesn't see my display as hdmi 1.4 capable 3d...tmt5 trial version does)

There could be an increase in ghosting if there is a synchronization issue of some kind. However, I tend to agree with you. After all, its the projector that syncs the ir-signal for the shutters with the incoming frames from the hdmi source....not the computer. Maybe the frame rate is slightly inconsistent coming from the card? Unlikely, but I would like to rule it out.

For whatever reason I do seem to be experiencing more ghosting than some posters with the same content. For example, the opening titles of The Guardians owl movie ghosts for the floating 3d titles regardless of warm up time. Everyone who has looked at this on my PJ can see it. At least one poster here doesn't see this....and for me it is hardly subtle. Everyone should see it. I also see flicker...and others apparently are not seeing this.

I also get picture breakup into blocks with avatar 3d randomly...so there is an issue there.

I might just try my luck with either a (returnable) ati card or a (returnable) stand alone blu-ray player to see if it makes any difference. I will post the observations here.

I have now tested with a stand alone blu-ray player. There is no more or less ghosting compared to nvidia card + htpc. As I have now solved my PDVD issue (with a simple re-boot of all things) I won't bother with ATI. The wierd thing is I have to set the mode in PDVD to 120Hz nvidia in order to get the player to playback in 3D 24FP 1080p mode.

Just watched some scenes from the owl movie and avatar during the tests... this PJ really delivers the WOW factor on my HP screen. The ghosting really is no big deal 99% of the time...and after the warm up time I have noticed it to be reduced.

Its finally time for me to run my cables...all this testing is finally wrapping up.

Yes, Mike, the projector takes 10-20 minutes to warm up to the point that ghosting is non-issue for me. Also, it ghosts less in high lamp mode. The extra heat, apparently, allows the chips to change state faster.

I'll be going through the process of trying to get my two HTPCs to talk to the RS40 soon. I have an nVidia 450 in one and a 460 in the other. I was an ATI guy for years, but nVidia worked with Adobe to get support for CUDA accelerated video editing, which makes a tremendous difference in how fast I can get things done. Also, I was having issues with black levels with my ATI cards for the last couple of years. So far, knock on wood, they haven't reappeared since I installed the nVidia cards. Those two things alone make it worth my while to stay with nVidia. I'll get the computer 3D issues sorted out, I'm sure. Right now, it's not as high a high priority for me.

It sounds like your PJ has about the same amount of ghosting as mine does. Have you tried Despicable Me yet? The white backgrounds seem to be really ghost-prone. The 3D titles in the owl movie ghosted much less after I switched to the newer AMD card, and the 3D effect was of course more pronounced. Although there is still ghosting, the feather that pops out when the owl dives down in the front of the movie title seems to project much closer to me than with the Nvidia card. My projector was thoroughly warmed up for all testing. I guess I could put the 450 back in and try out the new drivers just to be sure.

I've tried different HDMI cables and have even bought an HDMI 1.4 receiver in the process of chasing down these ghosts.

I recently borrowed a friend's PS3 but have not played a 3D movie with it yet. The killzone3 demo (720p i think) ghosted like crazy and looked like garbage, though.

Interesting that you mention the breaking up into blocks during difficult scenes. I occasionally get that too! I thought that my 6850 card, i5 2500 and 2000Mhz memory would have enough horsepower to render 3D flawlessly. Maybe it's an issue with the software player (TMT5) or drivers.

My latest moment of 3D amazement was the dark title screen for Tangled. I think overall, 3D pop-out effect on RS40 just seems to work better with light colors on dark backgrounds. Movies like Avatar that have "shallow" 3D depth overall tend to be good.

Hello there the title is quite exhausive, I have a WinXP-32 based HTPC and I'm getting crazy on trying to have 3D framepack output from HDMI to my new JVC-RS50 PRJ.
I use PDVD 10 latest patch build, Catalyst driver and everything from ATI is the latest release.
PRJ is connected via HDMI, I don't have any problem with my PS3 standalone player, that worked fine since the very first time, so no issues at all for the prj and cable. Prj is set to auto detect 3D mode, but I went through all manual steps ande they work fine.
Is all about EDID I guess, I don't see any chance of finding the Frame pack manual setting in PDVD and when is about to choose the display type I see only Checkerboard, Anaglyph or LCD Mini polarized. The image on the guides show 1080-24p 1.4 3D enabled should be there to choose but there is no trace about that choice.

Any clues??

Do I miss anything, refresh settings are to 1080@24Hz and the prj is set to primary.

Any help would be really appreciated!!

Thank You in advance Guys.

I tried any search in the web but no traces.

Sorry but I'm a newbie!!

did an EDID overiade so all 3D funktions where supported according to the EDID. and ran PowerDVD mkII with hdmi 1.4 output.

Hello there, would You consider being so kind to send me the EDID override you're describing, I seem to have EDID problems with my 6870, it doesn't see the 1.4 compatibility with my RS50, so no 1.4 1080x1920/24p 3D enabled screen shown option to choose. No framepack enabling.

Maybe You could be so kind to send me the correct procedure.

Thanks in advance

sorry if this has been mentioned before, I have gt430 graphics card. if I want to play 3d to a 3d projector like the new hd33 or something similar, do I need 3dtv play? or do I just need something like TMT5? if I play a side by side format film, wouldn't it be the projector that I just set to side by side? really confused at what the 3dtv play is actually doing and why I'm spending 40 dollars for it.

Nvidia does make it very confusing when I read the website and I've owned their products for over a decade now.

Here is the deal: If you own the Nvidia 3D vision transmitter and glasses (these work with 3D games AND 3D movies), then you do not need to spend the $40 to get 3D working on your 3D projector.

If you just own the GT430, they are charging a fee to 'turn on' the ability to play back 3D through an application like TMT5 or Powerdvd 10.

I don't think the cost is too bad, but part of me thinks they should provide the support without the additional fee.

It does work very well and I've watched over 40 3D blurays with TMT5 and PDVD10 without issues using the GT430. It works great with my JVC RS50, Sony HW30 and the Acer 5350. I do own the Nvidia kit because I use it once in a while for 3D games on my Acer 5360 3D DLP.

let me know if you have any other questions.

I thought there was a s/w driver that spoofed nvidia emitter. Also, isn't the fee to turn on only if you don't have a HDMI 1.4 projector ?
robl45's Avatar robl45 01:25 PM 09-11-2011
see this is what I don't understand, I open up powerdvd and tmt5 and they have multiple formats for 3d, now I understand maybe if you play full on bluray3d disc that it might need to do something special. but if you play a side by side video. does't it just pass that through? or is it the resolution bump or something that the 3dtv play is doing? I mean 40 bucks really isn't a big deal to pay or anything, just don't want to be paying for something I don't need when I'm mainly watching side by side files. I don't really care if I have to manually put the projector into side by side mode.

3dtv software is needed if you wand 3d games, fot 3D movies pure TMT is enough, however not sure about the supported formats (SBS, etc).

I would try it when you get the projector and see. I can't see why SBS wouldn't play back fine with just the regular drivers.

Hi guys.
I have this set up: Jvc rs50 and an Htpc with Gt 430. I manage to play stereoscopic 3D sending signal from Hdmi to pj and sound with a DVI to Hdmi to my Avr (1.4a) but I didn't manage to play side by side 3D even when I manually select sbs on the Jvc. Can anybody help me how to do it?
Joseph Clark's Avatar Joseph Clark 12:48 AM 12-05-2011
You have to select SbS in the JVC's menu. It's buried in an HDMI sub-menu. If it won't engage, it might be because the video format isn't supported. SbS mode for 1080i/60 and 1080p/60 signals is supported, but 1080p/24 isn't.

Does anybody knows witch is the minimum Ati video card with Hdmi 1.4 that supports 3D (framepack sbs etc. all types if possible) for my 2nd Htpc to connect with Jvc rs50 and an 1.4a Avr. I am not interesting on games but video playback only
