I just read something on a 'private' list that I'm not certain is correct or not but if so, we're SOL:There is NO support for 10 bit color for any version of Windows OS except for Windows 7
Hi Andrew,
Yet on other places we can read "both Windows 7 and 8 have built-in support for 30 bit output, but if you use Windows 7, you will have to turn off the Aero theme". If that's the case, then it's most likely that Windows 10 will also support 30bit output, but we'd need either a reliable user experience report that can confirm it, or something credible from the horse's mouth (Microsoft or nVidia). OpenGL support for 30-bit output seems to be an important prerequisite, as is a Display Port interface.
Lot's of info on the internet, some of it is actually correct...
Cheers,
Bart
