On 10-bit, YCbCr, DisplayPort 1.2 and HDMI 2.0 dongles

Question asked by andygoes on Dec 21, 2016

I have many W-series FirePro cards at my disposal (5100, 7100, 8100, 9100) for use on an Intel i7-based Windows 7 x64 Pro PC running the 15.301-160403a-301263E driver.

 

I am trying to determine if any of the following are possible on a JVC DILA-RS600U via active DisplayPort 1.2a to HDMI 2.0 dongles from Club3D (CAC-1070 http://club-3d.com/index.php/products/reader.en/product/displayport-12-to-hdmi-20-uhd-active-adapter.html ) and Accell B086B-011B (DisplayPort 1.2 to HDMI 2.0 Active Adapter | Accell ):

 

- 4096 x 2160 @ 60Hz YUV* 4:2:0

- 4096 x 2160 @ 30Hz YCbCr* 4:4:4

- 4096 x 2160 @ 30Hz YCbCr 4:2:2

- 4096 x 2160 @ 30Hz RGB

- 4096 x 2160 @ 24Hz YCbCr 4:4:4

- 4096 x 2160 @ 24Hz YCbCr 4:2:2

- 4096 x 2160 @ 24Hz RGB

 

- 3840 x 2160 @ 60Hz YUV 4:2:0

- 3840 x 2160 @ 30Hz YCbCr 4:4:4

- 3840 x 2160 @ 30Hz YCbCr 4:2:2

- 3840 x 2160 @ 30Hz RGB

- 3840 x 2160 @ 24Hz YUV 4:4:4

- 3840 x 2160 @ 24Hz YUV 4:2:2

- 3840 x 2160 @ 24Hz RGB

 

*I'm happy to have someone explain to me the difference between YUV and YCbCr as neither AMD nor NVidia use these uniformly, and the projector does not understand this correctly, either.

 

I can't even get the cards to output 10-bit unless I have them set at 1920 x 1080 @ 60Hz, and can only change the pixel format to YCbCr when I emulate as an HDMI Passive Adapter. In the AMD FirePro Settings, I have Enable 10-bit pixel format support checked, but when increasing the resolution I end up with

 

For comparison, on an NVidia K5200 and 6000 using a passive DVI > HDMI adapter, I can pass 4K60 12-bit YUV 4:2:0 effortlessly.

 

Thanks in advance - I hear @fsadough might be able to help!
