PRS-T1 Ghosting? - Page 2

Kolenka · 10-14-2011, 03:34 PM

Even with a full refresh, most eInk displays will have a little bit of ghosting. I had a TON on my iRex DR800, and it was noticeable in periodicals where pages were formatted similarly. It was so blindingly obvious it was annoying.

The 650/950 I have also ghost, more than my T1. Easiest way to see it is just putting the device to sleep. Couldn't tell when reading a book though. Not sure if it is just a trick of the eye or what.

Yours looks a tiny bit worse than my T1 (I can't really pick up on it, but I can detect it now that you mention it on the home screen), but still worlds better than the DR800 I had.

FWIW, my 950 (which of course has full refresh), has some light ghosting also.

When reading a book, and turning to the next page T1 does full screen refresh and I never see ghosting when reading a book.

expect too much? forgive me because this is mine first pearl reader, but my pb360 Vizplex's full refresh shows zero ghosting at any page. Plus I also see ghosting when reading which is very annoying especially toward the end of the chapter when only a small paragraph left and the rest of the page looked like a outline of the previous page. Maybe I have been pampered by mine pb360, and maybe most other readers do experience ghosting, but i ask the question if this is normal and a few said no, so i naturally assumed something could be wrong with my T1.

That shouldn't happen if it's doing a full refresh.

This would drive me nuts and should not be accepted. I don't have ghosting on my 505 and only one time a week on my 950, the other thousand times a week no ghosting. Isn't there a manual screen configuration setting on the T-1 like the 950 where you can correct this?

No ghosting here.

Thanks for agreeing with me and there is no configuration that fixes this problem. Its sorta like reading a paperback made out of semi transparent paper. Sigh and I am still waiting to hear from sony.

Here's my 2pence-worth. I have a PRS505, PRS650 and PRST1.

The 505 has never had a ghosting problem.

The T1 has never had a ghosting problem but, since it's less than a week old, the jury's still out.

The 650, now and again, certainly does have a ghosting problem. Sometimes it's happened twice a day, other times several weeks go by without it happening. I can tell when it's starting to happen, page turns become slower and it's as if the device is struggling to refresh the page and only a slow partial refresh happens. It is not comfortable to keep reading in this state. However, the good news is that if I do a full device shutdown then turn it on again the problem has gone away (until the next time). I've been carrying on like this since December 2010. I should have sent it back but because PRS650's became a scarce commodity I didn't want to risk losing it altogether.

That does not look right at all

I do not have any ghosting while reading a book, although I can see the text from a previous page for the shortest time, then its gone. However, if while reading I go to the menu settings (to change the font size for example) there is ghosting, then if I go back or foward a page, it disapears.

I had two 900s, one 350, one 950 and I have played with my father's 900 and with two more 950s owned by colleagues.

ALL of them had as much ghosting as you are depicting in your pics.

Now, I don't know if I just have an insane amount of bad luck.... but in my experience, it is perfectly normal - and I don't really notice it, when reading. But, if I look for it, it's there.

If you think the ghosting is abnormal, then I would exchange it and try a new unit. Or, visit a local store that has demo models and see if it looks similar.

I have seen that on every eInk reader that I have ever owned, going back to a Sony 500. Including another 500, a 505, a 900, a Kindle 2, a Kindle 3, a Nook Touch, and now a T1. Seems to be inherent in the technology. You just get used to it. It does not really interfere with reading.

Did you receive an answer already?
I also have this problem, but if this is normal, it's not that bad.

Yeah, i got it exchanged. so far, zero ghosting in the menu pages and during reading. This is a hardware fault, if anyone experiencing any ghosting especially with readers like prs-t1 which only performs full refresh, you likely have a faulty screen, get it replaced.
