Anyone with a Dasung Paperlike 3 yet? Report?
JTL Thanks for the ideas. I will try ruling out the coating/reflection point very soon, but not sure how to test for dithering. Shouldn't dithering on eink be visible to the plain eye? I also saw this video on youtube https://www.youtube.com/watch?v=RxTeT6umEwc which shows that dithering on e-ink is possible and is being done but it also is quite apparent to everyone. For example with Dasung, no matter if I set 40 HZ or 80 HZ and move the cursor very fast, I see only single occurrence of cursor on screen, just the place switching of cursor is a bit faster on 80 HZ.
So I think for me the problem is with eye teaming, coating, glare, white color in general, because books does not dither for sure...

JTL c) possible dithering by the e-ink display (Unsure?)
According to DASUNG the E-ink monitor itself makes use of a dithering algorithm.
randomboolean the HD resolution is useless as it is impossible to read anything, it is too tiny.
Is not HD the main reason for purchasing the 3rd generation device instead of the 2nd? Do you know what the other improvements are going from Pro to HD? Is not there the option to switch between different resolutions as on standard monitors? Thanks on the Irlen syndrome, I will take a look!
The e-ink display on my yotaphone gives me eyestrain/nausea. I had previously used an e-reader for pdf reading successfully. I conclude it is the fuzzy look when e-ink screens animate movement, possibly similar to how dithering bothers me.
Onyx boox m92 - used a pearl screen and onyx's custom OS which they used prior to using android.
I don't know, but I do not think its due to hardware differences. The main difference is how I used the devices. With the Onyx e-reader I would spend 99% of the time staring at genuinely static text, and 1% of the time seeing the flash of the page refresh as I turned a page. With the yotaphone's e-ink screen I am scrolling, things are animating etc so I am constantly seeing these fuzzy partial refreshes. In my opinion, it triggers my symptoms in a similar fashion to dithering.

What was the reason why we only talk of Dasung, and Onyx was discarded?

Is it because of poorer quality, or because it works under Android with all the potential problems deriving from updates?
I bought a secondhand Dasung Pro for 500 euro (I`m in Ireland) with great expectations but it gave me an instant headache when connected to my Windows 7 PC. Even if it had not given me a headache I could never use it because it was useless for web browsing/youtube videos etc. About the only practical use would be word documents or reading books.

I have a DASUNG Paperlike HD and I love it. I cannot imagine to live without it because it´s the only way to not have eye pain. I´m not able to use any other normal screen as they produce me eye pain in just a few seconds. The only thing that I miss with DASUNG are the colours....
I had eye-strain, headaches, and other neurosurgical issues caused by flicker so severe that it forced me to retire. I currently use a 3 Dasung paperlike pro set up, and it allows me to continue to be a free lance programmer. for a long time i could only use the e-ink monitors and they were a life saver! the Dasung does not have any noticeable lag for office productivity/programming sorts of things. I think the other options that run android are pretty laggy. Now that the problems I had are less severe I am able to add a true 8 bit VA panel with high dpi 8 feet away and still suffer no ill effects. My issues were so severe in the early days an MRI showed measurable tissue death in my brain. the Dasung takes a little getting used to, but if you have severe issues with flicker it is a total solution. if your video card is dithering, you will be able to see it on the e-ink very clearly. it shows up as swarming on the screen. when you disable it, the screen becomes static and wonderful. I ordered all three of my Dasungs strait from China in 3 separate purchases without any issue (much cheaper). 3 years in, they are my daily drivers, with an additional VA when color is needed. for me this solution was not optional, I would not be able to work without it. I would love to get the new HD versions, but I have too much invested in my 3 paperlike pro set up. the bezels between the monitors are also a bit of a pain, but far less of a pain than headaches and brain damage.

The PaperLike pro does not use temporal dithering, it has different types of static dithering, but they dont cause flicker. When I dissable the FRC on the video card there is 0 flicker on the PaperLike Pro
