Why not just 2*1080p24, or 1080p48? PS3 and Blu-ray 3D will work perfectly fine, there'll be nothing sub-optimal about it.

It'll only be 1080p120 that could cause potential issues but that'll be entirely down to RAM and RSX power. As it is, 720p120 is something of a miracle in itself IMHO and much better than the lower resolution methods seen in Avatar by Ubisoft and Invincible Tiger :)

Because those formats are not supported(or defined) by hdmi1.3 which is in ps3. Ofcourse they might be able to break the spec and have some devices supporting the non standard output. Or perhaps the chip in ps3 would be partially compatible with hdmi1.4 spec?

I was meaning 1080p60(not 120Hz) where 2*1080p24 content resolution is halved and 3-2 pulldown is done. This would be very similar to what displays not supporting 24p input are doing. The resulting buffer could either be 1920*540left eye + 1920*540 right eye or interlaced format which alternates eyes between even and odd lines(and tv would scale that to 1080p). Ofcourse the player could also directly give 3d 1080p24 buffer with halved resolution if tv would support that.

So I think the question for sony would be that what format will ps3 outputting for 3d movies and do we get full resolution out of it?

AG: We support 3D today-we're a fully compatible 3D console, and I think it's just a matter of developers wanting to make 3D games and consumers wanting to bring 3D into their homes. I think it's unclear how much demand there is for that. I think it's clear that the technology is here, and I think we're seeing a lot of that, but it's a pretty big investment to buy a 3D TV. I mean, it's exciting technology, but when it will ever reach mainstream adoption is unclear to us.

Is this the same kind of 3D Sony is talking about or something different/lesser? Because he also mentions some XBLA game that you can "use with any TV", which sounds gimped..

There's a game supporting 3D that's been released on both PSN and XBLA. Also, Avatar's 3D modes are available on both consoles.

But it's the old red/blue type. Can 360 support newer 3D modes or does it need HDMI 1.4 or something?

:???: XB360 has no trouble rendering the same stuff as PS3. The question is if it can output the formats that the TVs will understand and display. I thought a higher spec HDMI was needed, which PS3 has been patched to, but I don't think XB360 has. And 3D over component is a complete no-no isn't it, unless some TVs support that somehow. Which would be news to me, and so few and far between anyhow it makes it irrelevant other than a tick-box feature.
 
Avatar does work with it somehow, so it definitely is possible, even if only in some limited form.
Seems like the game's so bad that no-one has any practical experience with it... ;)
 
Any idea what method they use?
Edit: This says HDMI only, 1080p input with 120Hz. Nothing about glasses-synchronisation. I'm confused!

I think the answer is yes to that. But you should add that tv should be capable of processing the 3d signal(which is not true for current 240Hz televisions as they are hardwired for 2d signals). Some tv's might be firmware upgradeable but I wouldn't hold my breath.

Then there is the open question of movies. In what format is the 2*1080p24 source material sent over hdmi1.3? Is it the feared 3-2 pulldown and 1080p60 which would half the resolution and cause jerky pannings or is there better kludge available that some future tv's can decode from hdmi. Another known hdmi output choice is the 720p 3d outputted similarly to superstardust(again lowering the resolution and making ps3 suboptimal player for 3d blu-ray).

Yeah, I will be shopping for a new monitor this year. It looks like I can divide the features this way ?

3D Ready TV/Monitor: 120Hz and above, as bright as possible (no numbers ?), HDMI 1.4 (Don't convert from DVI or component)

3D TV/Monitor Adapter: IR emitter to match with 3D glasses, 3D signal decoding

3D TV/Monitor: All of the above

According to my testing, Xbox 360 version of Avatar supports five different stereoscopic 3d formats (full checkerboard, 2 different half checkerboard formats, interleaved and left/right split). Nothing prevents other developers using all these same 3d formats in their Xbox 360 games.

You have to set stereoscopic 3d active from your TV set settings. TV set does not communicate in any way with the console about stereoscopic 3d settings. If the correct stereo 3d mode is properly enabled from both the console and the TV, then the image is shown properly. HDMI 1.4 might send have some extra information along the image for automatic 3d-mode selection, but with current devices you have to setup the same modes to the game and the TV set.

For one thing they are most likely limited to 60 fps as they use the bog standard HDMI 1.3, which efficiently means 30 fps games with the exception of the interleaved mode where 60 fps will be possible but where the resolution is cut in half.

With regard to HDMI 1.4 it offers a bunch of other modes as well, briefly explained here.
It also has a considerable higher bandwidth (higher resolutions), but the standard seems to offer different hw implementations with different capacities.

Twice the resolution. Avatar is effectively running transmitting two images within one 720p 60Hz output. The PS3 3D is sending a double-height (maybe double-width, but more likely double-height) 1440p 60Hz framebuffer. That's the difference and that is what is so significant about the PS3 update.

Gosh. Is there actually a 3D setting in your TV? Is this that common? Do the glasses connect to the TV or XB360? If the XB360, there should be no synchronisation problems at all.

It's synced to the TV, 3D ready TVs use a rather ancient VESA defined port for sync signals (ancient but still perfectly functional, with the new wave of 3D displays it will no doubt all go proprietary ... a step back).
