In the Onyx you have a GUI switch in the status bar. What I meant is, Floyd /dithering/ is (with all appearance) an implementation of rendering on A2 (which per se is only a hardware mode on EPD using only black and white in a fast manner), already working (very well) on the MaxCarta. It's what enables us to watch videos, for example.
In other terms, A2 is the way the dots are managed, electronically; the Floyd dithering is how the software on top decides to distribute the black and white.

Check that NXP document, it's interesting.

Actually the supposition was probably false. I downloaded a chunk of the video through clipconverter.cc . It seems to use all 16 shades. Please check the screenshot attached.
EDIT: Initially, I thought they were using a 4-shades technique, akin to A2. And looking at the screenshot again, it does look like that. But histograms show that all the range may be used - although the video conversion could have auto-interpolated the shot. I used 2160p to get a good idea. You would need real life experience to check.

Yes, the current info about the Max 2 HDMI does hardly stand. But again, if any further demo from the Dasung show a comparable ~800 lag, even half of that, there is something odd with the current technology; if not, with the Taiwan demonstration.
