Clara HD Sharpness Kobo

[Fenrag]

Hi,

About a month ago I bought the Kobo Clara HD, I come from a Kindle 7th generation, and one thing that brings me a little fly, is that, the first page that refreshes looks perfectly, sharp and with a "100%" black, but which happened to the next page, already loses the color, some words are more gray than others. All this has made me tell the reader to refresh each page, but it is a bit awkward to be watching the transition every little while.

I wanted to know if it's my thing, or the Kobo. Also indicate that I have applied some patches of geek1011 and I don't know if it could have been altered at some point. I use a new source the Amazon Ember, but with the Kobo Georgia the same thing happens to me.

Thank you very much!

You're probably one of those people who can only deal with eInk if it's set to flash on every page.

That option is available in the Reading Settings.

EDIT: Which you did. I can't read >_<".

Actual practical results depend heavily on the font, line-height, margins, font size & all that jazz.

But in Kindle this does not happen, can it be for different eInk?

Less ghosting on Kindles too.
I suspect same eink tech (original vizaplex, pearl, carta etc, depending on model) and different HW/SW.
I like the page to fully update, IMO better than the animation on LCD based apps. It tells me without me reading that I really flipped the page

I sometimes notice a wee bit of ghosting on my Forma so I've set it to refresh every page. I don't notice the lag but that could be because I've done that since the beginning.

@Quoth: A Clara should trounce an old Kindle on that front (ghosting), though (i.e., same hardware generation as the PW4/KT4, what the OP mentions is something like a KT or a KT2 (too lazy to pinpoint exactly, Amazon's marketing naming scheme is horrible, use the wiki for meaningful names)).

Anything earlier would be a dicier comparison against a similar Kindle (in terms of release date), but Kobo really picked up the pace w/ the Mk. 7 gen.

[Quoth]

I agree you have to compare the same generations.
I have a PW3, and while the contrast is poorer than the H2O original and similar to the Libra (I have both Kobos), there is worse ghosting on the Kobos if you look up a word or add a note. So much so that it it wasn't near the end of the page, I press both buttons at once on the Kobo Libra to refresh the page.
All three are set to refresh on every page turn.
I do prefer either Kobo to the PW3.

The absolute worst was my C version of the Kobo Touch. Dreadful ghosting and variation from nearly white grey to greyer grey. I have a Kindle DXG (B009, no KF8/AZW), a Kindle Keyboard (later FW with KF8 support but B008), A Sony PRS350 (touch & buttons) and a Nook Simple Touch (touch and buttons). None of them have obvious ghosting like the two newer Kobos, though much greyer, and all far better than the dreadful ghosting and grey on the Kobo Touch C.

Ah. Dictionary/popup behavior is indeed left to the mercy of the software implementation, because it's a very fine way to trigger ghosting in a whole lot of different ways (a region of misaligned text right on top of existing text), and flashing when showing the popup and/or when clearing it comes with its own set of potential drawbacks. It's my experience that doing that is better (which is why it's KOReader's default [in fact, the *full* screen is flashed when closing the popup to *really* avoid ghosting]), but I honestly don't recall what Nickel and the Kindle UI do.

I not have this problem of the fonts getting less and less sharp each screen change. I'm using a Kobo Aura H2O (original).

I've never seen that on any on my 3 Kobo models either, only the regular ghosting of a previous image.

I've seen that. But when it's just text, no problem with ghosting.

error please ignore it

I've seen it on every reader I've ever had. But only if I look closely. It's not so bad as the OP describes. Still, it bothers me and so I've set all my readers to refresh every page (except for the Nook, which doesn't have the option).

[Quoth]

Yes, though without every page refresh it's not as crisp it doesn't change much. I prefer the refresh every page apart from the better appearance.

nooks don't have a lot of things because the firmware is lousy.
