Yeah we should probably merge these two threads into one.
http://www.geekzone.co.nz/forums.asp?forumid=64&topicid=68445

No lossless audio for any 3D content, it's all downsampled or only picks out the compressed audio core for 3D discs.

I didn't know it was limited to 720P output only though.
If so this does knock the whole PS3 can play 3D discs thing really.
That would mean, yes it does play it, but at reduced quality on all fronts.

DarkCypher: Without knowing for sure, but don't you also need a 1.4 HDMI cable?


The HDMI 1.4a cable is required for 3D content but as Gavin said, the PS3 should at least pick up that there is a disc in the system.

Well i presume it would of anyway..


I very much doubt you need a different cable for 3-D. It's really about bandwidth and most HDMI cables will cope with that fine.

For the new Ethernet link you might need a new cable depending whether the current "spare" pin actually has a cable in it and engineered in the right way.


Probably should have been more specific, HDMI 1.4a would be required for lossless audio and 1080P+ resolutions.


A manufacturer might engineer a cable to clear a certain bandwidth but the maximum bandwidth may be much higher.

In the case of 3D the bandwidth of a movie would be about the same as normal 1080p50 or 60 which most HDMI cables will cope with. If it works it works.

its only capable of 720p 3D resolution which is well inside the bandwidth specs for 1.3.


The PS3 is capable of higher resolutions for 3D content than that isn't it?

Yep, apparently it'll go 1080p.

So the PS3s max output resolution is 1080P? I was postitive that if there was Blu-Ray content that was recorded at a higher res the PS3 would hack it wouldn't it? Or am I wrong..

As for the audio, I have my PS3 set to bitstream running through my HDMI AV receiver, now that's lossless audio but I'm not running 3D for my display but if a user had a PS3 and a 1.4a receiver and the same version HDMI cable wouldn't they still be getting lossless audio?

I don't know, but in the AV settings, 1080p is the highest setting for video output.  Is higher than 1080p possible on BR or any consumer electronics?

No.  When the PS3 switches to 3D mode lossless isn't output any longer, the type of receiver is irrelevant audiowise.

1080P is the max PS3 resolution, and that of bluray. That's absoluetely standard.

When the PS3 plays 3D blurays, the audio is limited to non HD audio output, ie DD or DTS just like a DVD. This is regardless of the audio actually available/supplied on the disc. A non PS3 3D capable Bluray player will presumably not have this limitation.

I'm not sure if there are any BR discs that are available now with higher resolutions than 1080P but I read somewhere that BD's could support 1440P or even more.. Not sure how true this is though?

Really? Well thats kinda of crap.. I wonder if further down the track there will be new PS3's available that will support lossless audio and high res 3D output at the same time...

It's kinda crap, but considering how old PS3 is, it's a pretty good acheivement.  I'd take the option of 3D with reasonable audio over no 3D any day.  Maybe they'll figure out a way to do it later on?  Ditto with the menus etc.

Apologies, looks like the PS3 will support 1080p 3D movies but only support 720p 3D Gaming. The reason is due to the PS3's hardware not being able to generate enough fps typically 60fps for smooth gaming, where as its just playing the 3D Bluray (24fps) from the disc it doesn't have to generate anything just play the disc.

I can't figure out weather or not the HDMI port has been SW upgraded from 1.3 to 1.4, some forums say its has been and other say it's impossible as its hardware not software. Anyone care to answer this?

Same here I guess I wouldn't be complaining if I had 3D content output in standard Dolby Digital and DTS but you have to admit lossless audio is seriously awesome.

Lets hope Sony do bring it to the PS3's oneday.

langi27: ok maybe this is the answer.

http://www.gizmodo.com.au/2010/02/how-the-ps3-will-playback-3d-blu-ray-without-hdmi-1-4/


Sorry for my ignorance, but if the HDMI cable itself is 1.4a speed capable then won't that push dual 1080P through the pipes for 3D content? Or does the actual port on the PS3 have to support 1.4a for this?

Cheers.

The PS3 and the TV both have an HDMI chip, the cable is just dumb wires.

The chips have a certain capacity to process and output the signal and HDMI 1.4 is higher capacity than 1.3.

It appears that with the PS3 Sony have managed to get enough data /signal through the 1.3 interface to do 3D but may have had to constrict the maximum output to 1080i per channel and lower res. audio.

Ah I see so it is a chip in the port itself which allows it to process the signal for higher resolutions and audio for 3D content.

But how come then are there HDMI cables out there that you can buy that are certified for 1.4a and beyond speed capabilities? Is this just a marketing scheme or is there still some tech involved with it? In other words does one require the other to reach full potential in the output signal?

Again sorry for my ignorance.

Cheers

An HDMI 1.4 cable would be certfied for the bandwidth requirements of the 1.4 standard but many existing cables will still meet that standard.

There may also be some changes with regards to the pins reallocated for Ethernet and audio return but I'm not sure.
