And another message to Onyx, «Keep up the very good, clever and dedicated work you have been doing up to now!».

I am testing a different brand device, as I wanted to check a few things.
I see that their interpretation of A2 is "threshold" instead of "dither". When you enable A2 mode in this other device, all you see is silhouettes. When you do it on Onyx, dithering is applied to the distribution of black and white pixels and it is comparable to greyscale (while of course a lesser quality if compared to the proper greyscale of "Normal" mode).
To have that kind of quality (and attention) on the Boox Max Carta was a very nice surprise.
On this other device, A2 is only useful for its most basic feature of avoiding refresh flicker - but you will never be able to render video or images - including replicating a desktop usefully etc. (EDIT > ) You cannot even recognize icons. So, engineering the Onyx devices already includes features that are not to be taken for granted.
