Conclusion: The BM Mini Monitor card does indeed output 10 Bit on HDMI.
But: There might be some kind of "handshake" between the devices to configure the mode and maybe Eizo mucks that one up, resulting in the Mini Monitor switching to 8 Bit.
Resurrecting this old thread, since I just spent an afternoon researching this very issue. It seemed to me, after reading everything written about this, that this mysterious "handshake" is what specs keep calling "Deep Color", which must be something more specific than just 10-bit color, and must involve something mysterious. Also, "Deep Color" is a term that keeps appearing in the context of HDMI specs.
So I had an idea, and went looking for the official HDMI specification. It is a proprietary document, but I managed to find it (ahem
), and... guess what: it says that, when transmitting "deep color" (higher than 8 bit depth), images MUST be transmitted in RGB or YUV 444... but NOT YUV 422.
Now, the Mini Monitor's spec page (
https://www.blackmagicdesign.com/produc ... s/W-DLK-06) say that it has 10-bit color precision... but ONLY YUV 422 color subsampling. Noticeably, the "HDMI" portion of the spec doesn't use the "Deep Color" term anywhere. On the other hand, the Mini Monitor 4K's spec does say clearly "Deep Color" (and also says "HDMI Video Sampling: 4:4:4, 4:2:2 & 4:2:0").
Erik Wittbusch: I've been finding your posts about the subject everywhere (both here and in LiftGammaGain), since you seem to have a very similar setup to mine (I also have an Eizo CG247), and I've been following your email rounds with Eizo and Blackmagic's support. I don't know if you are still interested in the issue, but I guess this finally answers the question you had in this post (
http://www.liftgammagain.com/forum/inde ... post-56707). And that also means, I guess, that we now know specifically what to shop for if we want to send 10 bits to the Eizo...
