Trying to find info on cards that support 10-bit color for Resolve and Adobe products through an egpu. Anyone have a working setup? Mini itx would be a bonus so I don't have to mod my Akitio.

I think Nvidia Quadro cards might be your best bet for mission critical work like color correction.

Normally I'd agree with you but read that Resolve doesn't take advantage of the quadro's performance.

There's so much conflicting information that I'm hoping someone who is running a color / post vfx setup can chime in.

I don't know if there's a way to get proper REC709 or other colour spaces out of a computer video card. It may be 10 bit colour, but it will be RGB and not YCbCr so your colour work may be completely useless when viewed on anything other than your monitor.

I would advise an AJA or Blackmagic device to get proper broadcast outputs. Never trust the colour of your GUI monitors.

I was hoping with 10-bit output and newer 10-bit monitors with 14-bit luts & rec709 settings (BenQ PV3200 or EIZO CG318-4k) that we could finally bypass using SDI breakout boxes. Displayport has 10-bit 4:4:4 as well as YCbCr. These new monitors should be able to produce an accurate image over the Flanders or Sony 1080 panels i've been using as reference monitors for the past six years? I thought all we were waiting for was proper 10-bit color from the OS and video cards.

Sigh, after some more research on and getting all excited on finally having a color accurate single screen 10 bit workflow, well of course Resolve's GUI is 8-bit and the LUT's on the BenQ's are not user accessible. So yeah, at least there's CUDA acceleration in adobe right?

You can get a calibrated setup in Resolve; that's its bread and butter. The UI itself might well be 8-bit, but the image processing pipeline is all 32-bit. You do need to calibrate your monitor and use the correct display LUT in Resolve, but the catch is that you won't necessarily be viewing the same thing that you'd get on a TV monitor without going through a Decklink card or similar, due to the differences in the monitor types and protocols.
