That is impressive, though the display seems to be entirely in 1-bit mode, which is going to improve performance (and probably minimise ghosting) considerably.

That works for high-contrast content, but tends to fall apart where more subtle shading differences matter. Either greater pixel depth (16 greyscale shades are common), halftoning (surprisingly effective given ~300 dpi resolution) or dithering (somewhat higher quality, avoides Moire effects) would be able to tackle considerably more content well.

(Based on my experience with an Onyx MAX Lumi, similarly-sized screen, multiple display options, and a wide range of content.)

The article mentions that there is greyscale rendering possible, but that text is first rendered 1-bit, with 1-bit greyscale applied after a few seconds for antialiasing. My experience with high DPI (dots per inch) displays is that antialiasing is far less an issue, both because the individual pixel size is so small and because with a monochrome screen, the reduced resolution of colour displays (where three pixels are required to provide colour for any given region) isn't a factor. Effectively the pixel density of a monochrome display is about 3x greater than an equivalent colour display, based on the same nominal DPI / dot pitch.
