as the title say, does the GTX 1080 support 10 bit color output on DP connection to a true 10 bit monitor?

found some info that nvidia block 10 bit functionality on gtx graphics card, forcing people to buy quadro?
however, this feature has been reenabled some months ago on a driver revision, can anyone confirm? especially for the 1080?

Stated in a couple of reviews. Here is one. https://www.techpowerup.c...eForce_GTX_1080/3.html High Dynamic Range, or HDR, isn't a new concept in photography. It isn't even new to PC gaming, as some of the oldest games with HDR (using simple bloom effects) date back to the Valve Source engine (early 2000s). Those apps, however, used the limited 24-bit (8-bit per color, 16.7 million colors in all) color palette to emulate HDR. Modern bandwidth-rich GPUs such as the GTX 1080 have native support for large color palettes, such as 10-bit (1.07 billion colors) and 12-bit (68.7 billion colors), to accelerate HDR content without software emulation. This includes support for 10-bit and 12-bit HVEC video decoding at resolutions of up to 4K @ 60 Hz, or video encoding at 10-bit for the same resolution. EDIT: I guess nothing there specifically says it is over DP. Apologies.

so if I use DP on a true 10-bit monitor then it will be compatible right? and I can select 10 bit like in this video? https://www.youtube.com/watch?v=7-PSFc1nc2c

It should do 10 and 12 bit color over DP and HDMI. I forget which v erosion of DP added HDR support, but the 2.0b HDMI and latest DP version will output it just fine.

Higher end 4k TVs support it, and maybe extremely expensive monitors.

I can select 10 bit in the drop down when I am connected to monitors that are 10 bit capable, yes.

We have professional grade monitors at work that I was referring to. Some systems run the Quadro cards, others the 'normal' cards. It works on the 'normal' cards as well. Probably not something that is in most homes because of the prices.
My Dell U3415W allows me to select it, but it is actually 8 bit with dithering, so I don't know if there is actually any real benefit.

can you get permission to test geforce cards in the actual 10 bit monitor?

Nvidia consumer class cards (Geforce GTX) can only output 10 bit color in a Direct X11 exclusive fullscreen mode. To get 10 bit color output on the Desktop in a way professional applications use it you need a Quadro card and drivers. Nvidia is blocking this for Geforce cards, regardless of the control panel setting a Geforce card will not process/output proper 10 bit color output. Anyone in doubt just try this tool: http://www.necdisplay.com/documents/Software/NEC_10_bit_video_Windows_demo.zip Works with my Quadro M5000, fails with my GTX1080. Same PC, a NEC SpectraView Reference 322UHD-2 as Monitor. To test 10 bit output in DX11 exclusive fullscreen you can try this: http://forum.doom9.org/showthread.php?t=172128 Games that I know that can render in 10 bit with a Geforce card if your Monitor supports it: GRID 2, GRID Autosport, Alien: Isolation. There may be more now.

I guess that answers that with certainty.
The only users at work that would probably be able to truly notice any difference all have the Quadro cards anyway.

Only workstation cards output true 10 bit color for both Direct X and OpenGL. Geforce cards will support 8+2 dithered in some applications. At least this is the case for 900 series and below.
As far as Pascal goes. It will support 10/12 bit color in Direct X driven applications however OpenGL will still use 8 bit color. You will still need a Quadro with workstation drivers to achieve 10 bit in OpenGL.

is there a hack for 10 bit output?

+1 It works with DisplayPort but not over HDMI. I can't imagine nobody has found a way around this limitation on hardware that's obviously capable... I'm not surprised by NVIDIA pulling a stunt like this.
