3D vision help

I got a Sony 40NX700 in hopes that I would eventually get a 3d computer and to play games on it in 3d. However I have done some research and found that this might be impossible with nvidea, or ati. I found this link, http://www.nvidia.com/object/3dtv-play-requirements.htm... , with a list of supported tv's for their 3d vision gaming. There is the newer 40NX710 on the list but not my 1 year older tv. I was wondering, what is the difference? They are physically the same led screen, with HDMI 1.4, with the same 3d glasses, with only one cosmetic change (The stand can not only rotate from side to side, but 6 degrees up and down). I am wondering if I should go ahead with Nvidea or would I have better luck with ATI and there 3d system? Should I get the GTX 570, or the HD 6950.

For 3D vision, you need to have the ability to run it at 1080p at a refresh rate of 120hz. HDMI 1.4 is only capable of 60hz at 1080p or 24hz per eye in 3D mode. I'm fairly certain Nvidia requires a dual link DVI connection for 3D vision, which that TV lacks.

For AMD's HD3D, you are automatically limited to 720p at 60hz per eye. The only 1080p option they have is 24hz per eye, which is only good for movies. AMD's version also requires HDMI 1.4a, that TV does not support HDMI 1.4a (and some monitors that are 1.4a aren't listed as such under general specs, but you can often search for that info).

Neither are going to work for you in the way they are intended. I don't know if that means you can run in 3D modes that are not recommended, but I doubt you'd want to.

I know that some tvs are 120hz, or so they say, cause they are only interpolating the frames in-between to create a smoother image. I am pretty sure that this tv is capable of 120fps, with that being said I have used the red cyan 3d just fine. I do not currently have the glasses so I could not test it out on an older computer. So even if I am wrong, and have totally wasted money on this tv, which card is better? I am leaning toward the GTX 570, the frame rates are very similar except in some areas were the 570 exceeds the performance of 6950. So I willing to suck up the fact I bought a new tv because it looked nice and was on sale, so I might buy a 3d monitor instead. Where would I get one? I am in Canada, so if it possible to find a canadian supplier, that would be great! Thanks again!

Sorry, I made a mistake with the model number. It is a 40NX711, so it is the newer 710 and that tv is supported.

Without dual link DVI connection to the TV, you are not capable of viewing 120hz at 1080p. As I mentioned, HDMI is limited to 60hz at 1080p. For movies, that's fine, but not for gaming with shutter glasses.

Red cyan 3D will work, because it doesn't need to create a separate image per eye. It only creates 1 image, and the glasses filter out part of the image due to the eye glass filter. This technique actually works with all TV/monitors.

However, AMD's HD3D requires HDMI 1.4a to be complaint, which that monitor isn't, and 3D vision requires at least 100hz, which you cannot achieve at 1080p, although you may be able to at 720p. I'll test it out with my setup now.

That is not a 120hz monitor. It does not offer true 120hz.

So that would stop me from 3d gaming, right? Even so, how much do these monitors cost? So should it be the 6950, or 570?

The Monitor in my signature works with both AMD and Nvidia's 3D vision. It's a full kit and is a little less than $700.

If your goal is 3D gaming, I'd go for the 570, as the Nvidia solution is a lot better for 3D.

Yes, but I am planning on getting another one of these cards 6 months later, AMD had better scaling for multi GPUs. Wont AMD release their own 3d set pretty soon to compete?

The difference is small and it won't matter if your plan is 3D gaming.

AMD HD3D does not work with crossfire, Nvidia 3D vision works with SLI.
AMD HD3D does not work at 1080p, Nvidia 3D vision does.

Hi All

I wanted to respond here and make it really clear on our product support.

For 3D Vision, we do not support any of the new 3D TVs on the market. We only support the monitors, notebooks, and projectors listed here http://www.nvidia.com/object/3d-vision-requirements.htm.... 3D Vision monitors are capable of 1080p60.

We do have a software product at NVIDIA called 3DTV Play which supports HDI 1.4 3D TVs. This software is included free with 3D Vision kits or you can purchase it for $39.99. It enables all of our 3D Features on your 3D TV. http://www.nvidia.com/object/3dtv-play.html. 3D TVs are only capable of 1080p24 (mainly used for Blu-ray 3D) or 720p60/50 support.

If you have any more questions, please just ask.
