The Glo HD on the other hand, seems less prone to uneven rendering of the e-ink text. On the Glo HD, I have the refresh set to refresh every 12 pages.
Just wondering if anyone has noticed uneven blackness in the e-ink on the H20? I'm wondering if this is the norm. My Glo HD does show some unevenness in the e-ink after multiple page turns, but it isn't as pronounced as the H20's unevenness. Increasing the line spacing on the H20 mitigated the effects of the e-ink unevenness somewhat.
Edit: this is using sideloaded epubs BTW.

Is the unevenness: 1) some parts of individual letters appearing lighter than others; or 2) some whole words or areas of the screen appearing lighter than other areas?
Although ghosting causes both types of unevenness, I think it is the choice of font that mainly the affects the first type (or at least affects how noticable it is), while it is the layout of the book that affects the second type
If you go for a number of page turns without a certain part of the screen being used, but without a refresh, then when the next page makes use of that part of the screen it will look darker than the rest of the screen.
For example, if you read with a ragged-right margin then the extreme right of the screen gets less use than the rest of it, and so when you do get a word that appears at the extreme right after a number of pages without refresh, it will look darker.
If you read with the text fully justified, and with lots of hyphenation, the words will be more evenly spread on the page and it is less likely that are patch of the screen will go unused for too many pages.
There are other things that can cause similar effects, such as paragraph spacing in some books that causes lines of text to fall in the less-used area between the lines of previous pages.
