Hi

Would appreciate some help.

I am working on a problem for a client. He is using an AMD Radeon Pro WX7100 card driving a 30bit Monitor but can't get a 30bit workflow in PS to work.
I checked the drivers and the card is set to 10bpc. PS is set to use the card in 30bit, but... a 10bpc reference image is still showing banding so I'm assuming we are only 8bpc. AMD state the card supports 10bpc. Does Ps support a 30bit workflow with this card?

Thanks in anticipation.

I feel your pain mate; however, I received a answer from AMD directly a day ago. (Not the speediest service, eh!) ;-)

After recreating my setup in their labs and testing, I was told the issue was confirmed and is fixed in the next driver release. What's kinda worrying is that this card has been on the market for a year or so; It concerns me that a card aimed at Pro's that's supposed to support 30bit open GL in PS and has been set to 10bpc in the driver, has been pumping out 8bit and no-one has noticed it prior to me raising the issue with them. Anyway at least they seem to have fixed it. We will see when the next driver is released.

I tried sourcing an answer from AMD but no-one seems to be able to resolve this. Very frustrating.
My client was going to buy another 5 of these cards for his design studio workstations but it looks as though I'll be directing him to nVidia Quadro cards after this experience.

I have the WX 7100 also and NOTHING except 3Ds Max supports this card.....NO CAD OR renderers use this card series yet...I think Radeon screwed us all on this to try and fund there Vega tech and left us WX series owners in the dirt...I have 2 Wx 7100's and found out NOTTENING but 3ds max uses multi gpu's so I wasted 800 USD......yES I am pissed....Never will go AMD again..Plus it seems EVERYONE and there Grandma supports Nvidia and gets extra goodies like ray tracing,god rays,hairworks ext ect ect.......

Oops. According to some sources, Radeon Pro is the new FirePro. And then there's this: https://community.amd.com/thread/214322

I suppose there's only one way to find out for sure: does it use the same driver release as the standard Radeons or does Radeon Pro use the FirePro driver?

Checklist:

video card in question
DisplayPort
30-bit capable monitor
30-bit checked in Photoshop
66.67% zoom and up
probably Windows 10. Win 7 had unstable 30 bit support. That's consistent with my own experience and everything I've read.

According to the info on this AMD site, the Radeon Pro W.. and FirePro W... share the same driver (currently version 17.Q4)

Ouch. That's me over here in the corner, with the pointed hat...I'll just sit here for a while...

So the question is why JGMUK couldn't get it to work. I had problems myself in Windows 7 (but not 10), so that may be it. And of course, it has to be a DisplayPort interface.

Photoshop, as well as all other major graphics and CAD applications, use OpenGL for 30-bit display. Only the FirePro and Quadro lines can do that, with their own dedicated drivers.

The advertised 30 bit support in Radeon and GeForce cards is for DirectX.

Even so, OpenGL 30 bit display in Photoshop only works at 66.67% zoom and upwards.
