To go above 24hz, you'd have to drop your resolution to 720p. With an adapter, the bandwidth is still going to be that of the weakest link, the HDMI connection.

HDMI is just not capable of doing 120hz at 1080p, which is what is needed to manage 60hz per eye. The bandwidth is just lacking currently. There is some new standards that may come out in the near future, but your TV won't change.

Nvidia's 3DTVplay is also just as limited by HDMI. That is why 3D Vision used dual-link DVI, because when it first came out, that was the only connection capable of 1080 @ 120hz.

Btw, 720p isn't too bad when using 3D. It definitely isn't as good as 1080p, but it will give you a decent HD3D experience.

Wait, did you say you have a passive system? A passive system should have no issues, though you aren't the only one who has mentioned this limitation. It's also very strange that a 120hz TV would not be active. Are you sure that is not an active shutter system? Can you post a link to the TV?

If he doesn't have to charge the glasses then it's Passive. And it's not true 120hz, no TV is. I have a Passive 3D TV that is "labeled" at 120hz. Using Nvidia 3D TV Play, I can only do 3D in 720p to get 60hz(fps). Passive doesn't change the limitations of HDMI. The only difference Passive has is the way the glasses work with the screen. While active sends alternating screens to each eye, Passive uses the glasses to block out half of the resolution for each eye. Each system is still required to draw everything on the screen twice.

i saw in this link

http://3dvision-blog.com/7163-make-your-passive-3d-moni...

it can enable using trough hdmi 1080p 60hz in 3d mode is it possible to do the same with amd cards with edid override inf to get 3d trough 1080p 60hz?

thank you for your help.


No where on that link did they say it would work at 1080p and 60hz per eye. I've seen a few people with passive systems and 3D Vision using the 3DTVplay software and still not get 60hz per eye at 1080p.

The first post said nothing of it. I read the "bloody post".

If you wanted to talk about this post, then you could have posted it first. Anyways, good luck.

You do know he wasn't trying to be a smart @ss by and saying "Read the bloody post!" right?

In the second link he posted it's to a forum and a user named "Bloody" posts a message relevant to what is being discussed...
