HTPC, 3D Vision, DTS Master Dolby True HD...Tricky
One problem I see coming for [us] 3D vision users is getting TrueHD (lossless) audio over HDMI using 3D vision. To get Dolby True HD or DTS master audio in Bluray over your HTPC (with an Auzentech HomeTheatre or Xonar HDAV 1.3) you have to run your video out over to the HDMI input of the sound card and then output HDMI over to your receiver. Now when you run your video and audio to your receiver and then finally to your TV. 3D vision will NOT detect your 3D ready display because it thinks the terminal end is your HD receiver and treats it like it is the display. Now I've handled this problem in gaming and to get digital 7.1 audio out of my receiver is to run my other display port out of my GTX 295 straight to my TV so that 3D vision will detect my display. This requires setting up extended desktop with two displays (which windows will treat your HDAV receiver as the second display), if I do not do extended display, sound will cut off on the receiver. If my receiver doesn't get a video signal it won't play audio over HDMI (in other words, it won't do HDMI audio only. My receiver is a Sony BDV-IT1000ES). This doesn't seem like the optimal way to handle the problem. Will 3D vision be able to detect the terminal end as 3D vision ready with a second step through a receiver? It seems like it should. Any thoughts?

Wow, if this is really the case I'm disappointed, since this is the type of setup I will be migrating too. Another reason they just need to let us override detection already!

Any solutions to this problem? I have run into this as well. I hadn't used my 3d vision glasses in awhile and since then I had to upgrade my receiver and in so doing went with a hd audio capable receiver obviously. So now nvidia recognizes my display as the receiver and says it is not a 3d compatible display. It was working before when I was running straight from the pc to the tv, was just wondering if anyone knows of a fix or if there is one on the horizon. I am waiting on the 3d blu rays to come out and I am thinking of getting the new power dvd to check out the 3d converted dvd feature.

I don't think that there will be an elegant solution to this until new equipment emerges that support true 120hz or more (receivers, switchers, etc)

I too have this problem and had to be quite creative to make it work properly.

The major problem resides in the bandwidth that the receiver or other parts of the setup can maintain.

120hz is usually not supported yet on receivers and other devices. I have an Nvidia GTX250 which goes to an Asus Xonar card which then goes into my Integra DTC 9.8 pre-amp and finally is going to my Acer H5360 projector.

First problem - Asus Xonar can not handle 120 hz.

Second problem - neither can my Integra pre-amp.

Third and final problem - the pc will only see the last string of the chain - the once facing it - in this case the receiver / pre-amp.

I want to use the Integra pre-amp for all my other video needs because it contains nice Faroudja enhancing technology I want to use.

So you have your two outputs on your video card. If you want 3D you have to make one of the two your primary output. Your second output needs to maintain the sound. You do have to [b]clone[/b] both monitors. Only your endpoint will accept 120 hz so you have to split the video and the sound somehow AND distinguish from the appropriate sources. In my case I also have an ExpressVU HD satellite receiver, a Laserdisc player (Yes I still have one of these) and ... a VHS player as well. The laserdisc goes into an Svideo connector so does the VHS. Both are upscaled by the pre-amp. The sat receiver is connected via HDMI to the receiver as well. So how can all of that be working at the same time?

An HDMI remote controlled switch sets between the receiver and the projector.

This way the HDMI signal destined to go to the projector from the PC in 3D can be switched directly to the projo without being processed by the pre-amp. The sound still gets into the pre-amp and both work at the same time.

Twisted, but it works.

I can now have TrueHD, DTS HD Master AND 3D all at once. Bring in the 3D blurays - I am ready!

Ok thanks for the reply. I will just use my 2nd vid output from my vid card to another hdmi port on the tv. Guess that isn't too horrible of a workaround.

I guess if I do a 3D vision surround setup with 3 projectors I will still have a video output free to do this? And then you mix D-BOX into the mix, what a mess because it doesn't work with lossless audio either..
