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. -- Regards wabe
