I have Optoma HD66 projector, dlp link glasses and powerdvd ultra 11. I also have avatar 3D bluray DVD. Try to configure different options but still not able to watch 3D movie:

Here is my setup:
* HD66 setting to 3D and DLP link.
* Powerdvd 11 setting "display device = 3d ready HDTV (checkerboard), source format = auto detect" Are these the correct setting? What else I am missing?

I also read that I need NVIDIA Vision glass and emitter? Do I still need it? I am just want to watch movie with projector, no game.

BTW my PC configuration is like this: 3.4 ghz triple core AMD, 8 gb RAM, Geforce GTX 550 ti card, bluray drive 12x. Windows 7 64x.

Pls help. Thanks
Alpharetta.

Yes you still need one nVdia emitter.

^^

If you already have DLP Link glasses, then technically I think you only need the nVidia emitter plugged into a USB port to "activate" the nVidia 3D drivers. You can still use the DLP Link glasses if you want.

There was discussion a couple of months back about a utility that was available to spoof the emitter. I think people were reporting success in using it to get around the nVidia requirement and enable the drivers.

You're right; corrected my previous post. But i didn't check that utility.

Hey Guys,

I have been playing around all day with 3D settings with my HTPC and new Panasonic GT30.

I got SBS mkvs working fine, which was almost automatic, and after some trouble I figured out how to get 3D working with TMT5. But I am unsure on how to auto switch from 1080P 60hz in windows media center to 1080p 24hz automatically as TMT 5 mentions that 3D won't work in 60hz mode.

So, is there a way to auto switch to 24 or is there some other refresh rate that I should use that will be good for both?

There is quite a bit new terms that confuse me so sorry if I skipped passed the answer already.

Thanks

If you play BR 3D (i.e. Frame packing) and if you see stereoscopic 3D, then the graphics card is sending video signals at 24Hz (1080p frame packing won't work at a refresh rate other than 24Hz). Why worry?

Hey renethx,

Thanks for the reply, but maybe I didn't quite explain that right. In normal operation the tv is at 1080p 60hz. There doesn't seem to be an option to put the tv into a 1080p 24hz mode unless it is the seperate 3d resolution listed in the Nvidia control panel. So when I launch a bluray with mediabrowser, the tv is in 60hz mode. And when the bluray starts I get a warning about it.

The only way I get the 3d signal is when I manually go out of mediabrowser and into the Nvidia control panel and select a 3d resolution. So it's kind of a pain.

Is there something I am missing here? Do I want to have a 1080p 24hz full time resolution that can auto switch to 1080p 24hz 3d resolution?

Thanks

In my case, TMT5 automatically sets the refresh rate to 24Hz when 3D playback starts (I see it by sluggish mouse movement), then it automatically reverts to 60Hz if TMT5 is closed.

This is similar to the issue I had after upgrading my NVIDIA drivers away from 260.99 to support madVR.
I had to manually change to 3D resolution to watch 3D BR and manually switch back to 1080p60 when the 3D movie is over.
I am now running the latest version of TMT5 (.114 or so) and the latest version of NVIDIA drivers and things are back to normal.
The auto switching works as it used to...

Gotcha, so basically it is looking like maybe the software versions are what's different in my case.

So the latest of both seem to work? Could one of you guys possibly give me the versions of Nvidia software and TMT you have?

Also, off topic, but balky, are you using mediabrowser by chance with madvr? I am attempting to use shark codecs which now has lavcuvid, lav audio and I am trying to get madvr in the mix.

Thanks

EDIT: I see that I am running .110. I will update TMT and go from there.
post #882 of 1485
So I updated TMT to the latest build and it is now switching to 24hz automatically. But when I get back to media center it stays in there. So I am almost where I wanna be here.
post #883 of 1485
This is probably a really stupid question.

I have been running an ATI 6670 but decided to try an nVidia card to see if it would help solve the problems I had with the drivers.

So I went and bought a cheap GT440 card, removed the ATI stuff, installed the GT440 and the latest drivers from nVidia's web site.

I am sure I have missed something basic because I find that the nVidia card will not activate 3D when I start playback of a 3D BR in TMT. It seems I have to go into the nVidia control panel and activate sterescopic 3D manually. That switches the display to 24 Hz but then I have to go back and restore to 60 Hz (my normal setting) after playback.

Also, with the nVidia control panel set to stereoscopic 3D it will send a 3D signal to the TV as soon as I start playback of a 2D Blu-ray. So the TV throws up its idiotic "put on the 3D glasses" message.

I can't believe nVidia requires manual intervention for 3D playback. At least ATI has that working automatically...

RTFM?
post #884 of 1485
Activating stereoscopic 3D in NVIDIA control panel is necessary only once. After that everything should work automatically as stated in this post.

That is not the way it works here. I have set the nVidia control panel setting:



With the display set to 60 Hz, if I start playback in the TMT 7MC player of a normal 2D Blu-ray the display is switched to 24 Hz and the TV throws up its "put the glasses on" dialog. I have to hit OK on the TV. Then the disc plays back seemingly correctly in 2D even though the TV thinks it is getting 3D.

Stopping playback returns me to the TMT drive selection screen and the TV again throws up the glasses box. I have to hit OK on the TV again. After exiting TMT, returning to 7MC, the display is still on 24 Hz.

The exact same thing happens when I play back a 3D disc except the TV presents it in correct 3D.

Should I expect the same behavior with the nVidia card as I had with ATI?
post #886 of 1485
I have continued to have some odd behavior lately.

When I hit stop in TMT5 to get back to WMC, the TMT 5 screen is windowed. Then hitting the back button to get to WMC, WMC is windowed as well. Any idea what is up with that?

Thanks

Did you run the setup wizard? I think you have to do that. I have a gt430 and it changes to 24fps and back to 60fps as it should, but I do have the same thing happening with my Samsung plasma. Whenever it switches to 24fps the tv thinks it's getting 3d. I haven't tried to troubleshoot it yet, but creating a custom 2d resolution in the Nvidia control panel. I know a lot of people in this forum have this working correctly, so hopefully someone could help us out here.
post #888 of 1485
Hi to all,

After upgrading from ati to nvidia 430 i'm able to run 3D blurays with powerdvd 11 or arcsoft 5.

Both player have a lipsync / audio delay when running in 3d. In 2D or SBS files there is no lipsync problem.

tips ?

Yes, I ran the wizard.

So that's not it.

I did a very thorough clean out of all the ATI stuff.

I reverted back to my ATI 6670 with the 11.8 drivers and I have perfect 3D playback with my player (TMT) automatically setting refresh rate to 24 Hz (and back to 60Hz at end of playback) with both 2D and 3D Blu-rays.
Unfortunately, however, I get jerky 2D playback every 20-30 seconds making 2D BD essentially unwatchable. Older Catalyst drivers (11.5) resolve that problem but creates a different one - 3D playback is downsized to 720p.

I was hoping these problems would not be present with the GT440 card - true enough, but there were other more irritating gremlins as described in my earlier post.

I am now inclined to stay with the 6670 and wait for a combination of ATI drivers and TMT 5 which solves the stuttering problem without breaking anything else. How likely is that?

Or am I likely to be better off with nVidia, possibly following a wipe and W7 rebuild, in the long run?

I certainly do not want to have to bring out a keyboard and activate/deactivate nVidia 3D every time I watch a 3D DVD...
post #892 of 1485
it seems the nvidia 3d vision video player (1.7.2) requires purchasing nvidia 3dTV play to work properly, is this supposed to be the case? TMT 5 works fine.

i have a gt 430 (280.26 drivers) connected to a sony xbr hx909:

- without 3D Play installed i just get over-under from the Nvidia player (or stereoscopic player), although the the screen changes, mouse becomes jittery and the TV detects it as frame packed 3D so I can not even manually select over-under

- with the 14 day trial of 3dTV play installed, everything works as it should, frame packed 1080p is sent to the TV. i guess i have to pay another 39.99 to get the nvidia player to work properly?

anyone know of a fix? thanks

Hi,

I'm using XBMC for any 3d files (SBS etc). This work fine, i need to switch my TV to 3d and select the correct mode (like sbs). I have no 3dtv play or 3d vision player installed.

3dTV play is used to play games or any other software in 3D. It seems to have no impact on 3D bluray except using cheap colored 3d glasses in stead of the regular.

For 3D bluray the driver switch to a 3D mode (activate by enable 3d vision in the driver settings). The TV detects this signal and switches to 3D.

For the 3D bluray i have powerDVD and TMT 5. Both work fine with 2d but having lipsync problems in 3D.

All ati driver are gone, but the lipsync problem with 3d bluray remains.

I had the same jerky playback with nvidia, disable the auto pulldown (Inverse Telecine (3:2 & 2:2 Pulldown Correction)) in the video driver fixed it.

I have the same audio sync issue with 3D movie

After a couple of test, the issue is the latest video drivers from nvidia

thanks!

i was hoping to maintain the quality of full resolution 1080p files

half-SBS works fine with MPC-HC, but the nvidia 3d vision player can output full res frame packed hdmi 1.4 video (e.g. from full-SBS, 3840x1080), but seemingly only when 3DTV play is installed

once the coreMVC codec is released, you can use the 3d vision player to play ssif files at full resolution as well

Recently decided to jump on the 3D bandwagon. I use my HTPC also as a desktop - and switch between using my monitor and the projector. I've been doing this now for over a decade, but NVidia is driving me crazy

I got
- NVidia video card (GT 430) that replaced an older ATI card.
- Denon AVR-1611 HDMI 1.4a receiver
- the new Optoma HD-3300 projector

My LCD monitor is connected via DVI. HDMI goes to the Denon receiver. Denon's output goes to the Optoma projector.

When I use Dish as my source, Denon & Optoma work well. No problems.

But, I can't get the PC video output though the receiver to Optoma. I can directly connect Optoma to the PC and make it work.

Looks like, when I just connect the receiver to the PC (without connecting the PJ), NVidia sees it as a 1080i "display" and outputs 1080i - which Denon works with. But once I connect the PJ, NVidia sees it (though the receiver) as a 1080p display and outputs 1080p60 ! Receiver will not handle this (or it won't pass it to the PJ). So, no video on the PJ.

How do I control this behavior by NVidia card ?

There are some other issues too (like when I connect my monitor to NVidia card by VGA, it will only output XGA ! or as soon as I switch on the receover, the display is switched and I don't see anything on the monitor - nor on the PJ). But we can get to that later.

Oh, BTW, is there a way to setup hot keys to switch displays on NVidia ? When Vista came out, NVidia control panel wouldn't allow this forcing me to switch to ATI. Does NVidia support hot keys now ?!

I am looking at building a small mini ITX based system. I have been looking at the AMD E-350 based motherboards which have been getting good reviews.

I have scoured the Internet until I got dizzy with all the code names - Brazos, Llano, Hudson, etc, etc. but I CANNOT find a reliable answer to a simple question: will the E-350 APU support Blu-Ray 3D in the same way as the 6670 I use in my current system?

Meaning works with TMT5 to automatically notify my LG TV that it is sending 3D with no manual intervention required.

I used to think that requires HDMI 1.4a support but after reading all the confusing information about the E-350 I am not so sure anymore.

It seems the E-450 APU is confirmed to have 1.4 but there are no mITX boards with that chip yet.

Other option is to go with a H67 based board and an i3 processor but that will be significantly more expensive. I have to use IGP since I need the PCI express slot for a tuner card.

Last night I managed to set the PJ to 1080i as well, this allowed me to get PC video on the PJ through the receiver.

But as soon as I change to 3D - I either get garbage or nothing.

I was wondering whether this is a cable problem - even though when directly connected tot he PC, PJ works with the cable I'm using.
