Not sure if this is helpful, relevant, or even meaningful, but my understanding is that regular geforce cards only support 10 bit in a directx environment, whereas you need the quadro for 10 bit open gl support (although it's disturbing that Chris is having issues despite his quadro card).

Hello, sorry for an off-topic question: does anybody have a working setup in Linux like: x nVidia GeForce & Display Port & native 10-bit depth LCD x nVidia GeForce & Display Port & native 8-bit + FRC LCD panel [1] [1] http://www.tftcentral.co.uk/reviews/dell_u2713h.htm or http://www.prad.de/new/monitore/test/2013/test-asus-pa279q.html Based on earlier announcement [2], nvidia binary driver for Linux supports 30-bit depth (RGB) in X for some time already. I succeed turning it on and got some glitches / colour artefacts as described on oyranos blog [3]. [2] http://www.nvidia.com/object/linux-display-ia32-295.20-driver.html [3] http://www.oyranos.org/2014/05/image-editing-with-30-bit-monitors/ However, the 1024-step ramp remained displayed on my U2713H with 8-bit gradation only (in Krita with OpenGL backend on, which is one of the few apps supposedly supporting deep colour output). Also dispcal with ColorMunki Photo reports 8-bit precision of video-card LUT only. I have access neither to Quadro card nor to native LCD to do more tests. So, has anybody made GeForce to output Deep Colour in Linux or is it a futile effort? (I have been googling and asking for a few weeks now w/o success.) Regards, Milan
