Sony announces no 1080p resolution for 3D games on PS3; will leave strictly in 720p.

According to Joystiq , PlayStation 3 games in 3D will have their HD resolution capped. While demonstrating the newest version of the system at the Develop Conference,  Sony representative Simon Benson announced that games that run at 1080p resolution will be downscaled in 3D mode -- per eye -- to 720p.  

Speaking to
Joystiq, Benson stated that although the PS3 has the capability of displaying a 1080p image, a  resolution higher than 720p has been restricted because Sony contends that a higher frame rate would impact the quality of viewing.  

Blu-ray movies will retain the 1080p resolution.  Blu-rays run at 24 frames per second, but games run at 60 frames per second -- upping the resolution for games would compromise the smoothness of the frames.  While a "more cinematic game" could be equipped to handle the 1080p resolution at the cost of frames, Sony's current guidelines won't allow users to change settings, Benson said.

A true 1080p image consists of 2M individual pixels, about twice the amount shown in a 720p image. Benson added that even trained computer graphic artist could barely tell the difference between resolutions.

On the Newbies Inc. website, Benson indicated that  that online gamers with a 3D TV may have a competitive advantage over those playing on HD sets.

"It all depends on the gamers to be honest. Initially we were slightly concerned about this because we were thinking, what if it makes it twice as easy or something like that."

He also stated that 3D can have the effect of making games more accessible for inexperienced players.

"I think what’s basically going to happen is that anyone who has stereoscopic 3D televisions and, for example, is playing a driving game, I would imagine you’re likely to find that the accessibility level is higher, that people would generally perform better on their first go. But I think at the high end with the hardcore gamers you’ll still see a [3D] advantage there, potentially, but the margins will be far smaller."

They should point out that 1080p@60hz per eye isn't possible yet with HDMI. You need a dual link DVI cable to handle that much bandwidth. I think HDMI 1.4 can handle 1080i@60.

Also, this sentence doesn't make sense:

"a resolution higher than 720p has been restricted because Sony contends that a higher frame rate would impact the quality of viewing."

They're using frame rate and resolution interchangeably.

1.4 has the bandwidth for 1080p/60 as well as 4Kx2K resolution.

True but this article is about 1080p 3D content. From Wikipedia:
quote:
"HDMI 1.4a requires that 3D displays support the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24, side-by-side horizontal at either 1080i50 or 1080i60, and top-and-bottom at either 720p50 and 1080p24 or 720p60 and 1080p24.[114]"


Note there is no mention of 1080 p 60 in there.

Copy that. Still reading papers on HDBaseT. Too many specs!

Not necessarily; they're saying that with the finite bandwidth or processing power, there's a trade-off between frame rate and resolution, as upping the latter may impact the former.

No, they're confused. This should read:

quote:
"a resolution higher than 720p has been restricted because Sony contends that a lower frame rate would impact the quality of viewing."

So it was just misspeaking. All of the other comments seem to quite clearly recognize the trade-off between resolution and framerate given static hardware.

Guess what...the PS3 does NOT ship with an HDMI 1.4 port...so doesn't matter, they're limited to the original specs that max 1080p out at 24fps. Maybe new systems will come out with an updated port, but what about the millions already out there?

Wonder if they can push more in a different way. Like create an adapter to utilize the HDMI port and component connections.

Out of interest, what is possible with the component video output that the original xBox 360 was release with? There are still a few of them about in the wild, so I assume that MS would have to take that into account when deciding on specs like this if they want to produce 3D content too.
