That's not true. You have actually the option to play games in 3D in full HD @ 24Hz.

For some kind of games this is sufficient and it looks much better than 720p especially for games than can not use Anti Aliasing (either internal or forced by the nVidia control panel, e.g. Mafia 2).

Does anyone know if there have been any announcements on a new HDMI standard that would support this? It's really frustrating only being able to get a 27" solution for true hd 3d.

I've tried searching around on google for stuff but still can't find anything. :(

This topic was around 2 years old zeno.

A new hdmi 1.4 chip is out(whos to say if any display will support it/when)
300mhz hdmi 1.4 which will support 1080p@60hz. However you will need a display that supports and a video card.(nvidia currently does not have one). Amd's 7970 is the only video card that supports it.

If you do the math, HDMI1.4 has enough raw bandwidth to do 1920x1080 /120.

@Chopper thats what I was talking about. That is the chip in the amd 7970.

@roller11 the cable does, the chip doesnt. A new chip has been developed and is in amd radeon 7970 for 1080p@60hz. We are just waiting for displays to support.

I don't think the chip is any different on the 7970 compared to any GPU that has supported DL-DVI (going back to G80 I believe as the first).

TMDS already supports 330MHz frequencies, HDMI 1.4a or "Fast HDMI" ups the spec to 340MHz, so that's probably how AMD came up with their "3GHz HDMI" support since effective frequency is 10 x pixel clock. I'm not an EE but the one thing I've learned observing and using tech over the last 20 years or so, its usually not the conductor itself that's the limitation, its the signaling components on either end. Graphics cards have supported the required frequencies for years and have put them to use with DL-DVI, we just need the HT/HDMI components to catch up. The physical wire and conductors probably won't change much at all, except for maybe exceptionally poor quality cables existing HDMI 1.3/1.4 cables should work just fine handling the higher frequencies.

I'm optimistic Nvidia will be able to support Fast HDMI 1.4a/3GHz on all their recent graphics cards, its just a matter of when they announce/release the feature, and the only thing that will drive that will be an actual product capable of benetting from the extra bandwidth. We'll have to wait for a 3D Vision monitor or 3D HDTV to support this new spec before we see support from Nvidia probably. Maybe we'll see it announced with Kepler even if there's no products on the market that support it.

Here's the links and relevant portions I referenced to come to my conclusion:

...The DVI specification mandates a maximum pixel clock frequency of 165 MHz when running in single-link mode....

...In modes where each pixel uses 24 bits of color data per pixel or less and dual-link mode is in use, the transmitter stripes pixel data across both links; each sequential video pixel is transmitted on alternate links. In modes with color depth greater than 24 bits per pixel, the second link carries the least significant bits of each pixel.[/quote]

The main problem is, that a HDMI-cable(Type A: 19 pins) is identical to a Single-Link-DVI cable. There are only 3 Data-wire-pairs to transfer the data. At the moment it is not possible to send more data through this wires safely. The bandwidth of this cable is too low.

Huh, i keep hearing the cable itself is not the problem, but it is the 2 processors on both ends of the cable.

That post is 2 years old lib. But yea you are right. its not the cable(which is pretty much = to dvi-d in bandwidth) its the chips.

I think nvidia will support fast hdmi on all their chips, its just a matter of when. Hdmi is pretty much the standard now. You don't see dvi-d on hdtv's or projectors. Only some monitors.
The wires will remain the same.(at least thats whats been said)
