Perhaps I can place the monitor on my scanner and take a “screenshot” that way xD

Re: refresh rates I can’t find a good stat with a brief googling but it’s a Boox Mira, E Ink VB3300-NCD

You can tolerably watch video so somewhere north of 20fps but there’s ghosting. A friendly button on the front of the display is there to do a hard refresh if the artifacts build up too much. But yes I should do a comparison on how different desktop environments do, with animations turned off etc, scrolling that jumps line by line like vim or eMacs will work better than smooth scrolling for instance.
