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].

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
