Given that both devices have the same resolution, what do you think accounts for the better readability on the dr800? Is the document rendered larger on the dr800 due to less interface elements / smaller margins?

You can see, that in the oldest display from the Iliad, there are a lot of "stuck" pixels. These will not change their color and make the screen more "gray". The current displays are much "cleaner".
It would be interesting to know if these stuck pixels on the iliad are due to immature manufacturing or general degradation of e-ink displays over time. I wonder if a conditioning program can be made to work those pixels back to working order by repeatedly performing solid white and black transitions.

Quick, everyone get your microscopes on all your readers and specify age and usage habits!
