If I understand it correctly, in general the hardware-calibrated color accuracy and the wider gamut should "just work", but the 10bit support can be tricky. It is supported on Linux with the proprietary NVidia drivers (has to be tunrned on manually), but not with the Free drivers. On the application side the support is mixed, with KDE and Gnome supporting it and some other Environments not. My tool of choice for Photo editing, darktable, currently does not support it, but I would be willing to work on that=E2=80=A6 So my question: do any of you have experience with this? Are there reasons why the nvidia driver on FreeBSD should not support this, while the Linux one does? I can hack on the application side, but if the stack straight-out doesn't support it, I would not want to spend 1000=E2=82=AC on a screen t= hat looks like a 500=E2=82=AC screen.
