FAQ for the 3D HTPC - Page 14

Is an HDMI 1.4 cable absolutely required for Blu-Ray 3D playback through the 430 card? Because the new card arrived today, has been installed, but no 3D.

Since I was getting 3D from the Panasonic DMP-BDT100 player to the Panasonic TC-P50GT25 50-Inch plasma using a 3' HDMI 1.3 cable, I figured it might work for the HTPC.

TMT 5 is configured for the first 3D option on the list (HDMI 1.4 ready TV.) The rest are all for LCD or DLP, so I did not choose those options.

The Panny plasma is set for "Auto Detect" 3D mode.

The Nvidia settings on the PC are 1920x1080 24hz.

So I'm guessing it's the cable?

Stereoscopic player has a dual screen output option, and a "dual screen stereobright" option, not sure what the latter is. Sounds like one of those will do what you want though. It's a free trial.

Unfortunately, it won't let you play 3d Blu-rays though.


On another note, I'm trying to figure out if it's my new AVR3600 or something with the ATI 6850 that's the issue here. Basically, it supports HDMI 1.4a, but when running through the receiver, it switches the TV into 3D mode and then doesn't display anything. Connected directly to the display works, so sounds to me like it's the receiver, though maybe the card is doing something abnormal too, I'm not sure.

No, i don't think you will need any HDMI 1.4 cable if you don't have an HDMI 1.4 AVR between your HTPC and TV.
You will need this cable when you want to pass frame packed stereo files together with HD audio.

Try to use first: DVI (dual link) to HDMI (with your existent 1.3 cable over a DVI to HDMI adapter or another DVI to HDMI cable) > to your TV's HDMI input.

It seems to me an EDID issue. AMD never gives supported AVR list for 3D while nVidia does, you know.

Thanks for the tip! I'll try it out and report back.

Gave that a try just now to be sure, and the .inf created by Moninfo for passing the signal through the receiver (with HDMI bypass on, which according to the receiver manual is necessary for 3D to work), is identical to the one created by Moninfo connecting the video card directly to the TV.

Thanks for the suggestion though. Wish I had another HDMI 1.4a capable source so I could narrow it down to the PC versus the receiver.

SUCCESS! I updated the 430 drivers with version 260.99 and ran the "stereoscopic 3D setup" from the Nvidia control panel. I now have Blu Ray 3D (through a regular HDMI 1.3 cable.) The first time around, this didn't work correctly. It even says in the update notes: "Stereoscopic 3D> Added support for Blu‐ray 3D disc playback with GPUs connected to HDMI 1.4 3D TVs."

btw, I did try the DVI/HDMI adapter before I did the driver update, no joy. Should have updated the drivers first, and I would have been off and running from the start.

Also found that I need to disable "stereoscopic 3D support" in the Nvidia control panel when not viewing 3D movies, otherwise the desktop has a grainy appearance. Weird!

Thanks a bunch for all the helpful advice

HAPPY HOLIDAYS TO ALL!

I got my HTPC assembled last night and I'm watching Shrek in 3D today. Thanks for the help. I do have a question on the Nvidia emitter. I turn the dial on it but I don't see anything happening. Should I? Where do most people have the Nvidia settings at?

i'm pretty sure the dial is just for 3D games, I don't think it will affect anything while viewing 3D movies.

I setup my JVC RS40 projector last night and tried to setup the GT430 card. There is a bug somewhere (likely with the JVC) where the projector will see a 2880x1080p signal from the graphics card, no matter what the previous desktop settings are.

I will see windows booting, then once it hits the desktop, it syncs with some bad info and I am dead in the water. I tried the HDMI and the DVI port, same results. I understand another member had this issue and contacted Nvidia. They said it was JVC's issue. JVC said they didn't test the Nvidia card with their projector.

Does anyone know what might be happening here, and any possible workarounds?

Thanks for letting me know.

I can't wait to hear how the JVC compares to the Acer in 3D.

I do have two complaints with the Nvidia set up. Maybe someone has a work around so I'll ask. The green light on the emitter is annoying. I turned it toward the screen and its working fine reflecting of the screen. I eventually want to move it up by the screen though. Is there a way the light can be disabled during viewing? The other problem is I use an ir receiver to control my av equipment outside of the room. That receiver also flickers the whole time. I'm sure it picking up the emitter. I could put some tape over the light but that seems tacky.

Need help choosing between an Nvidia or ATI video card for my HTPC connecting to an Integra DTR-80.2 and a Panasonic TC-P65VT25. I have a Core2 Extreme Quad Core 2.66 with 8GB of Ram 520watt PS and Windows 7 x64 and TMT5. I am building this from parts to play Blu-rays and BD3D's. I want to pick the card that is going to be the easiest to live with and give me nice stutter free video and bitstreaming audio.

Thanks in advance

that's not going to happen for a while until I figure out the bug with the Nvidia card and the JVC RS40. The JVC thinks the Nvidia card is sending out a 2880x1080 signal and won't sync. I have to find some help in this forum to see if some folks have ideas on a workaround.

Is there any way to watch the Directv 3D channels with a HTPC?

Ok, so my hard drive is now bloated with 3DBluray ISOs... I do have a bluray burner, but dual layer BD-ROMs are still too expensive when I can get a 2TB external drive for about $100.

The question I have is, will USB2.0 be enough bandwidth to support 3DBluray ISOs? Last thing I want to do is buy a large external USB2.0 hard drive and have it stutter.

The DirecTV project to offer tuners for Windows 7 based systems was cancelled in the summer of 2007 and I am not aware of a another solution.

Looks like the optima box would be the only solution then.

Need some advice/suggestions here in my setup/issue

I am running a GT 430 connected to a Denon AVR-991 connected to a TC-P50VT25. I was playing with CyberLink PowerDVD10 and I can confirm that the Nvidia stuff works HOWEVER I am seeing the following issue:

When I switch in an out of 3D mode I have to switch from the HTPC input on the AVR back to the HTPC input on the AVR to see the video again. I know I am receiving video since on the AVR web interface I am able to see the HDMI status and the receiving source. I've disabled the IP Scaler on the HTPC interface from the Denon standpoint.

BTW I also have a PS3 and DO NOT have this issue with my PS3 when going to 3D mode and back.

Ideas?

Do you mean you have to disconnect and reconnect HDMI cable everytime?

Basically, i switch the source in the AVR input menu from the web interface and it the screen shows.

Really weird?

It will work fine I watched 3D bluray iso of resident evil off an external usb 2.0 hard drive just a few hours ago.

Thanks. I got my 2TB usb 2.0 drive last night and 3D ISO's work fine off it.

I'm having problems with TMT5 and 3D movies (iso). Everytime I play a 3D movie using Media Browser, my 3DTV (Samsung Series 8) does not recognize the movie as 3D. But if I mount the ISO, then launch TMT5 the 3DTV recognizes it automatically as a 3D movie and will prompt me to turn on my 3D glasses. How do I make this work with Media Browser?

All those commercial players need to open a disc. So at least you have to open an ISO file to listen HD audio, watch subtitles and 3D.

will Radeon 6850 gpu fit in a mini ITX case?

anyone have success using dual outputs (dvi + hdmi, hdmi x 2) from a nvidia 400 series or ati 6000 series card to enable both:

HD audio on a HDMI 1.3 receiver
3D bluray playback on new 3DTV (HDMI 1.4)

the point being to not replace the the receiver that is a couple of years old

EDIT:Confirmed later.

I did this with my GTX460 while waiting for my HDMI1.4 AVR to arrive.

It worked quite well except in a few instances with lip sync issues when playing MKV files.
Lip sync issue was gone when I put in the new AVR
