3D and HDMI

post #1 of 14

I ran some HDMI cables in my theater room during construction in '08. I'm now concerned I may not be able to get the 3D signal I'm expecting with my new equipment that I'm getting ready to purchase.

Here is the cable I have in the wall/ceiling...

I am purchasing an Epson 6010 and Sony Blu-ray BDPS780. I also have a Pioneer 3D A/V receiver (VSX-1021-K).

Any insight on what limitations I'll experience and/or options to improve would be appreciated.

Should be fine for 1080p24 3D (BD). Might or might not work if you are gaming with 1080p60 3D, assuming the PJ supports it. Might or might not work with Deep Color, again assuming the PJ supports it.

Wow, I'm surprised. I thought I was in trouble with the cables I have. Thx!

Anyone else with different results please chime in.

I would be concerned - from his link:

Quote:


720p/1080i Resolution - The Standard HDMI® Cable has sufficient bandwidth to transfer 720p/1080i video signals between 720p/1080i rated source and sink (display) devices.

That will work for Frame Compatible 3D formats (SbS & T/B) but will it work for Frame Packed 3D formats (3D BD & 3D PS3)?

That's a standard speed cable, not a high speed cable.

Lee-Bet it'll work fine for frame-packed 3D. Click on "Knowledge Base" for that cable and go to the end re. 3D capablity. I'm using 40+ feet of their 24AWG (thinner) "standard" HDMI cable and frame-packed travels from my Panny 210 BRP to my Epson 3010 PJ just fine.

Also works fine for frame-packed 3D when I use my Sony 570 BRP.

The HDMI cable specifications state that it was tested up to 165 MHz which is enough for both 1080p60 and 1080p30/24 3D. As such based on the cable specifications the HDMI cable should work. If you ever upgrade to a projector that is capable of 1080p60 3D (which has a 297 MHz signal) the HDMI cable might be an issue but even than there is a chance it could handle a 1080p60 3D signal with the help of a HDMI amplifier/equalizer.

The key that most don't understand is simple. If your HDMI (or DVI) will pass 1080p 60Hz it will pass 3D from a BD. BD 3D actually needs about 20% LESS bandwidth than 1080p 60Hz.

My HDMI cable I have from 4+ years ago does 3D just fine. Does that mean theres no such thing as a "high speed" cable?

Remember companies like Monster and Tributaries are HDMI.org members. They pushed hard for multi tier (for up sales profits) cables. HDMI.org agreed to for 2 levels. The requirement is for High Speed to pass a higher bandwidth signal than standard. It would be hard to impossible to design a standard HDMI cable (5 meters or less) that would pass the HDMI Standard test but fail the High Speed test.

So in effect High Speed is 98% marketing.

Yeah. That's what I was thinking.

Really appreciate all the info. I'm still a bit nervous about getting a 3D signal thru a 25' standard speed cable - but I'll just have to give it a try and find out if it works.

This thread at least made me feel a bit better.

Again, it's simple. Can you pass 1080p 60Hz right now? If the answer is yes then you KNOW you can pass 3D.

So far, so good. When I have the blu-ray player hooked up, the projector shows it's getting a 1080 signal. When using the DirecTV receiver, I get 1080i. As I've read, you only get 1080p with DirecTV on their PPV movies that are HD.

Have not tested that yet - but expect I'll get 1080p.

Tested a 3D blu-ray last night - looked good to me. Not the same maybe as I've been accustom to in a 3D movie theater, but their projector likely costs more than the Epson 6010.

The 2D to 3D conversion on a DirecTV signal seems a bit funky - tried it on basketball - maybe not a great idea. Looking forward to testing it on a 2D blu-ray.

Is the 1080p and 3D signal all or nothing? Or would it potentially be better with high speed HDMI cables?

Thanks again to all for input/analysis.
