I have two identical machines. GPU is Radeon R7 250E and Monitor is
a Samsung U32D970. Monitor and GPU both supporting 10bpc. One machine
is running Gentoo and the other Win7.
When I start Radeon Settings on the Win machine, it shows me that
10bpc are used. All graphic software that I use on the win machine
also supports 10bpc.
On the gentoo machine I use xf86-video-ati-7.10.0 and
xorg-server-1.19.5. When I look at /var/log/Xorg.0.log I can see that
only 8bpc are used.
At the time when I bought my monitor (nearly 3 years ago) I searched
the internet for information about Linux and 10bpc. All I found was
that it is not supported by the xorg drivers. As I do no graphic work
on gentoo this is not that important for me. So I never searched again.
Maybe it is supported now but I didn't read anything about that on the
xorg-announce mailing list so I don't think so.
Maybe other drivers (nvidia or proprietary amd) are supporting 10bpc.
But I never searched for that information.
Although the newest Gimp supports 16 and 32 bit images and also can
use these color depths on internal rendering, I don't know if Gimp
could support more than 8bpc color output if the display would be able
to.
