Nvidia 352.86 WHQL [8 bpc vs 12 bpc] color depth?

[zoomer-fodder]

Hello. Im install this new driver and find this feature.
Somebody can show me, how i can see difference with 8bpc vs 12bpc (bits per channel)
some special pictures?
may be my screen cant handle 12bpc...

I don't think your Samsung TV has 12bit colour depth. You'd need a professional monitor for that kind of setting.

8-bit color = 2^8 x 3 = 2^24 = 16.7 million colors
12-bit color = 2^12 x 3 = 2^36 = 68.7 billion colors

More colours = better rendition. Pretty sure it requires HDMI 1.4a anyway.

yes i have it connected. and i have autosuggestion, when i looking on my desktop picture im like more 12bpc picture.

I actually don't know. I spent a good 20 mins looking for detailed specs, and didn't find anything about 8bit or 12bit colour depth on that TV. Odds are with it being a 1080i panel it's only 8bit though.

You can test it by turning your NVidia drivers to 12bit and see what happens.

and im got autosuggestion! i mean when im looking on 12bpc desktop i like it more, than when it turned to 8bpc. blue color get some better))
im find this http://www.techpowerup.com/forums/threads/12-bit-hdmi-color-output-in-cat-14-6.202188/ but dont know can it help me understand it.
its like a DSR 4K on 1080p screen. looks realyy better, but it cant handle true 4K

All my graphics cards since my FX 5200 in 2003 (remember them?!) have allegedly been capable of showing greater than 8-bit colour, but I've never seen an example of such a picture.

I've still got a couple of CRT monitors knocking about to try this, but I think the standard DAC that comes with it may not be capable of greater than 8-bits - may have to be a Quadro or something which I have now, an FX 5700. Is it possible to do this and where can I get deep colour pictures to look at? I guess I could google for those pictures and see what I get.

Bandwidth is a constraint. HDMI 1.4a provides enough bandwidth for 1080@60p with 12bit colour, however it struggles with 3840@60p with 12bit colour. Older gen graphics cards may support 12bit colour, but the port on them may not output enough bandwidth to cope with the data.

You'd need a 12bit capable panel, with a port with high enough bandwidth to transport 1080@60p 12bit (aka HDMI 1.4a), as well as a GPU capable of 12bit with the same HDMI 1.4 output

EDIT: My knowledge is rusty, I've spent the last hour trying to make sense of all of it.

 

[zoomer-fodder]

Only HDMI 2.0 and new version can handle 4K @ 60fps. Absolutely all other 1.xx versions can handle maximum 4K @ 30fps

Btw Nvidia DSR can output 60Hz 4K @ HDMI 1.4x by 1080p screen.

Don't forget the most important thing. The content also has to be native 12 bit or else your color processor (GPU or TV) is just filtering up.

dsr render 4K@60 then downscale it to 1080p @ 60. this mean from hdmi to monitor we got only 1080p@60 signal.

windows desktop it is content 12bpc? (windows menu)

 

[Xzibit]

HDMI 1.3 or higher support up to 16 bit @ 1080p. As far as I know windows menu isn't 12 bpc.
