HDMI / DVI - Hz - understanding
  2 / 2    
Ah right, HDMI can only send 60Hz because as someone said it runs differently. Where as Dual Link DVI sends through 120 frames every second, HDMI when in 3D sends through 60 frames per second but both the left and right eye frames are sent at the same time and then split in to sequential frames afterwards by the TV, hence giving 120 frames every second.

Just to clarify. HDMI and regular DVI are basically the same bandwith. 3d vision needs TWICE the data to make 3d work. (basically 2d runs at 60frames....3d needs the other 60 to make 3d work). So in order to get the extra bandwith they have a DUAL LINK DVI..that means its basically TWO HDMIs stuck together. Now, when trying to game on a regular 3d HDTV there is a problem: How do we get 120 frames worth of data through a pipe that only supports half of that? there are 2 options:

1) reduce the resolution to half (720). This allows the 3d because instead of 2 channels at 1080..we CAN push two at 720.
2) if you must run at 1080 there simply is not enough bandwith to have 60 frames of each channel so you must reduce the refresh rate (frame rate) to 24. Which, in my view is unacceptable for gaming.

Option one works well....as long as lower resolution does not bother you. Unfortunatly we will not see FULL 1080 3d HDTV gaming until the allow a dial link HDMI...and that probably aint happening for a while.

So just to clarify with the Dvi to HDMi adaptor that came with the graphics card I can only get 1080p@24Hz or 720p@60Hz

I also have a Dual link DVI cable but for some reason at 120Hz the 3d does not sync properly and it just looks the same with or without the glasses.... could it be a faulty DVI cable?

Thanks guys

Yes the adapter will only support 720p@60 3D with a TV, and in fact with most 3D Vision monitors it won't support 3D at all because they will not trigger 3D through HDMI, only dual link DVI cables.

If you're seeing a double image, and there is no difference with the glasses on or off, there is more likely something wrong with the glasses.
Usually bad cables show them selves as no image at all or an image where it looks like you're getting half the horizontal resolution.

Thanks for your reply. @24hz the 3d works fine and I have 2 pairs of glasses.... :-/
