4K Ultra HD (3840x2160) stereoscopic 3D gaming (videos)
  2 / 6    
I think we're talking apples and oranges here. "HDMI" is a consumer specification for interconnecting consumer level appliances. Sony and the others have made lots of noise about 'consumer' 4K display devices. You don't really think your watching 1080P over HDMI on the big screen at the local theater do you? We were driving high resolution LCD displays long before DVI, HDMI or HDCP ever was invented. There's nothing earth shattering about clocking high speed data across parallel ECL lines. Over the +30yrs in the electronics industry I've worked on all sorts of things that you'll never be able to purchase at your local Best Buy.

No, he literally said hes using hdmi and nvidia card. Which cant be anything more powerful then hdmi 1.4. My main confusion is that regardless hdmi can't transmit that kind of bandwidth. I have to assume hes overclocking the pixel clock or whatever its called but I really dont think it could get that high either and then the memory on gpu seems a little too high. If I were to do 1080p @ 60hz on a single 680 I get a big warning saying memory low. Im not saying its impossible, it just doesnt make sense as far as I know.

[quote="eqzitara"]No, he literally said hes using hdmi and nvidia card.

(think going vertical as well as wide) Then again at my last job we had 6-8 DELL LCD panels combined (2x3 or 2x4) to make one WIN7 desktop. While I never tried running a game on the setup, its not beyond conception that multi input panels and the software to drive them exists.

Single card, Tridef. Nvidia hdmi does not support the high-power hdmi mode that amd does [but no display supports].

I have probabaly written too much and it became confusing. Also, it not general use here to output sth. and than capture it, and get the display signal from the capturing device. So what ever we output and capture, is viewed via the capturing device! At the capturing device I can connect any preview monitor, also a 640p if I want to - it is just to preview the capturing in any format. When capturing several full HD screens (at any refresh rate), produced by many GPUs and outputs, giving a total of any resolution I would like to achieve - I have he option to connect to the capturing deviced a display of my choice. I my case, when rarely doing single display, sometimes a 4k Sony via HDMI. But most of the time we go for multi 3d full projector setups - thats why I worte about how many stream at the same time that we can capture. Four full hd 3d devices equals one 4k at any 3d refresh rate. 16 of 720p 3d equals also 4k. In the professional industry, we stopped working with single projector setups a long time ago - even on relative small screens. We need infinite resolution and brightness - and we do not stop at 4k. Just a link that I can post that is general knowledge and a point to start: http://www.nvidia.com/object/nvidia-mosaic-technology.html http://www.nvidia.com/object/quadro-scalable-visualization-solutions.html And thanks mbloof for you clarifications, sounds like we both have the same background or professional history.

Surround Vision, Eyefinity, Commercial Display walls, etc.. is not being discussesd here. High resolutions are easily achieveable over multiple connections. What we are discussing is 4K sterescopic gaming. He posted in the "Nvidia 3D vision" forum. So my post was.... [quote="D-Man11"]huh? I'm pretty sure that stereoscopic gaming at that resolution isn't supported by Nvidia via a single output or even a dual output atm. So what exactly is your set up? Motherboard,GPU and CPU? What stereoscopic format are you using and at what refresh? Are you using a pixel clock patcher? How about telling us what display and connection you are using?[/quote] check it out....Nvidia does not support that resolution currently for Stereoscopic gaming via a single: output/cable/input or dual: outputs/cables/inputs There's lots of ways to push pixels, but keep in mind we are talking "3D Gaming" and not 2D or 3D Video. So yah we were talking apples, but somehow you saw oranges.

Yah multiple displays via multiple connections, it's possible, go figure... http://s6.photobucket.com/user/Bongo2k/media/quake-highres-plastknet.jpg.html?#/user/Bongo2k/media/quake-highres-plastknet.jpg.html?&_suid=137482059875607445075186575563

Great picture!!! I will send it immediately to a friend of mine, who is Quake addicted.

The single display 3d vision thing I can offer and capture, as written, is 4k at 60hz. 30hz and hopefully frames per eye. But right, the dispaly device has to the same thing when sending bluray 3d at 24hz. It must be multiplied to 60 or better 72 per eye. Not necessarily motion interpolation, but repeated frames.

Nvidia does not output that resolution. You're simply pushing a higher resolution via lower active pixels with lower pixel clocks. It's been done for years, so stop fibbing.

Relax - I get paid for what I am doing, because I am good in what I am doing. Even I do this private, I am still up to date But you should know: https://forums.geforce.com/default/topic/522300/304-48-major-bug-pixel-clock-ramdac-nvidia-drops-support-for-120hz-on-displays-above-1080p-/ It is all a software limitation, that can be removed. 3840x2160 at 60hz gives me a pixel clock of only about 517mhz. You are right, most likely not offical supported, and not known by you - but many people drive their 4k screen with 60hz.

Just tested: With reduced proches/blanking (very tiny), I can even stay below a pixel clock of 500mhz with 3840x2160@60hz.
