Dual HDMI for audio and video

[Baki Abdul]

I want to take 3D video signal to 3D TV and HD audio to my non-3D receiver. Can a graphics card having dual HDMI output perform the job?

Dual HDMI cables isn't going to help.

Your receiver might be able to pass through the 3D; I'm not sure.

The best option is likely to be to connect everything directly to your TV (rather than through the receiver), and use either HDMI ARC or an optical cable to return the sound from the TV to the receiver.

Hi Someone Somewhere,
My receiver is a NAD T747 that has HDMI 1.3 and doesn't pass thru 3D signal, and for that reason, ARC would not work. Optical cable cannot bitstream HD audio signal, it merely passes thru dts and Dolby Digital.
Well, can a DVI cable pass thru 3D signal to TV? Any idea? If it does, I can use HDMI from the graphics card for audio to the receiver and DVI for 3D video to TV. What do you think? Regards.

Ooh, looks like I misread the original post - I thought you were trying to connect both HDMI cables from the PC to the receiver for double the bandwidth...

Yes, connecting one HDMI cable to your TV for video and a second to your receiver for audio should work.

Hi, thanks for the reply. Now the tricky question is, while carrying 3D signal to TV, can the other HDMI bit-stream HD audio signals to a non-3D receiver. Or will it be a 2D signal to TV while simultaneous output will be working?

Another question was regarding DVI? Can a DVI connection carry 3D signal to TV?
Regards.

I don't know if DVI can carry 3D; I'm pretty sure it can't.

This might be specific to GPUs, so I think you probably need to just plug it in and try setting it up.

What about the 'tricky question' I asked in the previous post?

As I said, it might be specific to the GPU you're using. There shouldn't be anything in the HDMI standard that prevents it, but your GPU drivers might.
