30Hz (per eye) 3D TV. Why not?

post #1 of 7
Thread Starter 
I was thinking over the weekend (Dangerous I know), pretty much all films are around 23/24FPS. Why then are we told we need 120Hz TV’s for 60Hz per eye for 3D TV? Now I understand that it may be required for 1080i 60Hz broadcast TV but why can’t I watch my films at 30HZ per eye on my current 60Hz TV. Has anyone hacked the Nvidia drivers to allow it to lock at 30hz per eye with Nvidia 3D Vision?

I’d probably make the jump if you could do this as I’d buy the glasses but not need a new TV. I’d happily play 3D games at 30FPS as well.

30FPS (15FPS per eye) as far as I know, so I would say you would get about 15fps in games, unless you turn off v-sync?? I dont know to much..

They must of tried this when they devolped it, they'll prolly be some point (below 120Hz/60FPS per eye) where you notice the shutter opening and closing to much and it ruins the effect.

In the cinema (I know its different tech) the movies still play at 24fps and it looks fine.

Not all games will play at 60fps using Nvidia 3D vision as the affect essentially halves your frame rate. The games still work and look great and are certainly not playing at 60FPS per eye.

I have PowerCinema 10 and if I could get the Nvidia drivers to do work at 60HZ it can turn any movie into 3D. I have tried it with the Blue and Red effect that 3D vision allows you to try and it works pretty well.

When I say 30Hz 3D TV I mean 60Hz set showing 30HZ per eye.

Hi,
30hz just is'nt enough for 3d, well it is'nt for shutter glasses.
You would notice the blinking effect of shutter glasses really bad at 30hz i would think.
My 3dtv takes 60hz input but in frame packed format so i still get 60hz per eye.
