i LOVE my Dasung Paperlike Pros. I bought one at first because the purchase strait from China seemed dicey, but it arived and was of good quality, so I purchased a second one. The visual performance was way better than I was expecting. There is always very slight ghosting, but it gets erased by scrolling or refreshing during just normal use. there is a blink button that gets rid of all ghosting if the background gets muddy. I find myself pressing the blink every half hour or so. I have heard that others have had driver instability issues, but I never used any device specific drivers and mine have never had any issue of any kind after 4 months of ownership. The mouse thing I commented on is not really an issue. the Dasung has a slow refresh rate so you can see the dithering that comes through the video signal (my assumption). it kind of pissed me off how may things are a swarm of dithering, but when using the dasung it does not cause eye strain, rather, it lets you see where dithering is happening (all over the place). if you look closely at the icon that looks like a folder in windows for example there are moving dots about 0.5 millimeter in diameter moving around. this is not true of everything, only certain images. there are other images that only dither when the mouse moves. for example, the grey box at the very bottom of the vmware community page https://communities.vmware.com/welcome. it is a static gradient approximation pattern that moves with mouse movement but is otherwise static. I will upload a video at some point to better illustrate what I am seeing, but I do not have a camera. Short story, Yes for me the Dasung has been a solution to my problem. I would love to have color and bigger screen, but for me it seems like the only option. I think my symptoms may be at the high end of the severity scale. it seems like I have become increasingly sensitized over time. I cant really use any light emitting screens that I have access to. I am going to purchase a CRT to see if that is usable as a source of color when needed.

ShivaWind This is great information! Very exciting! I believe I am also on the high end of the severity scale. I cannot look at any screens without a blublocker clip-on. Even with the blublocker, I still get severe symptoms on many screens. For some, I can tolerate. It is highly likely the Dasung Paperlike can solve my problem since it is a solution for you. Thanks for sharing the information. I will place an order right now and I will report back once I have testing results.
Glad to see e-ink is a safe display choice. It also plays into my color theory, that Dasung only displays blacks and whites, so if color was a problem it would not be apparent.
Shivawind, does it have a backlight?
ensete Does not have any light of any kind.

So I can't say anything definitively yet, but I do have significant evidence that what I am seeing is in the video signal and not due to the panel. I was watching this utube video https://duckduckgo.com/?q=dreamweaver&t=hf&iar=videos&iax=videos&ia=videos&iai=ORV1HOSgv2Q and noticed that the "dithering" I see on the Dasung panel was also in the video. to describe it, imagine textures to be represented by a temporally static combination of wavy filaments and dots about 1-3 pixels in width that move with relative intensity to their proximity to the mouse cursor. Well, I noticed the "Dithering" --(maybe not the correct term here) in the white parts of the video following the mouse in the video not my mouse. I plugged in an old LCD and moved the video to that monitor, and could not see any dithering. Moved it back to the Dasung and the dithering was there. So there is strong evidence that there is some source of dithering on Max,Linux, and windows 8-10 that is present in the video signal regardless of hardware. My previous known good configuration was ATI graphics connected to 4k flicker-free 8bit benq with each head running through an HD PVR Rocket set to 23 and 25 hz refresh. on windows 8.1 deleting the monitor-device in device manager then setting the generic monitor device to disabled. then keeping some portion of webkit enabled active windows on each monitor so they would get conflicting clock edges. I cant say if my condition has progressed or if some update has rendered this no longer usable, but it seems like the no-light Dasungs are my only option now. I can say that the "dithring" I see on those is not eliminated by the DP_DisableDither reg entry with ati or by Ditherig.exe on Intel. It is present in differing levels on Linux and windows, but there in both. it comes in 2 varieties, always moving, and only moving with the mouse. The PVR rocket seems to act as a partial low-pass filter and reduces but does not eliminate the degree of "dithering". This is also true of virtual machines. At this point my observations have been casual, I will do a rigorous and scientific analysis when I have a better Idea of what I am looking for. I am not even sure if the “Dithering” I see is what makes me sick. After 10 years, the symptoms have gotten more severe and the brunt happens the next day so I am a little gun shy of using myself as a lab rat.
I know I owe a video, but I am such a PITA anti-smartphone guy that I have to eat crow in order to ask a friend to use theirs.
ShivaWind I should add that my previous known good configuration also requried dissabling 2 windows services. Fontcache and Netbios over TCP/IP the name of the second one may not be exact?
I wonder if the good people at Intelligent Optical Systems (IOS)
could shed some light on the problem https://en.wikipedia.org/wiki/LED_Incapacitator
Sure am curious about what that "evil color" is http://www.ledsmagazine.com/articles/2007/08/led-incapacitator-is-latest-weapon-in-crowd-control.html
I would be more interested in seeing one created from a cell phone. You could put the app on google play and let teenagers dare each other to stare at the screen. It could be like the next pokemon go! all we need is a catchy name. puke-eh-man go! then again, does the world need weaponized smart phones?
ShivaWind That's easy.
Just don't be the a-hole who did this.
Wish I could talk to Kurt about him and his photosensitive epilepsy. Since photosensitive epilepsy is also rare and not well understood.
ryans I'm not aware of any foolproof way to detect which devices will be troublesome. This is due to different people being sensitive to different aspects of the displays coupled with vendors using different supplies on the same device, and with there not being any real clarity on what the problems really are.
That leaves trial and error...
I have had my wisdom teeth removed, for sure. Martin, things I've considered:
- TMJ (I have mild TMJ and mild tinnitus, of the inflammatory variety... the muscles get swollen and it makes my ears ring and jaw ache, I sleep with a nightguard)
- Blue eye pigment (I am from scandinavian stock, but none of my siblings or parents have this issue)
All I know is that nothing definitively helps. I've had no eye problems on bad TMJ days, and vice versa. One thing that REALLY helps... is Lutein. I take a high-potency Lutein supplement and that is helping a LOT.
