I have lots of CRT monitors here.
CRT can display "infinite" colour depth (if you have a infinitely good cable... still, testing suggests that most VGA cables can easily support more than 48-bit colour per pixel)
380X is the most advanced AMD Card for end users, that still has a RAMDAC.
I own one.
So, does it supports "10-bit" colour settings at least? (this shows on RadeonMod for example).
Does it work for analog output?
Can it output HDR somehow?
Can I output, even if I need other OS than windows, a custom colour depth? (since windows, even Win10, seemly can't go beyond 24-bit when discounting Alpha Channel).
