your health

ShivaWind I will upload a video at some point to better illustrate what I am seeing, but I do not have a camera

Please do

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

ShivaWind I assume it's some super strong stroby blue LED.

I can make one myself with an Arduino. Don't need their overpriced garbage.

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?

JTL he deserved it (and more). I was there when it happened and it still cracks me up

degen He's strange man, that's for sure.

AgentX20 Is there any way of confirming which phones have this and which don't? For example Galaxy S5 does not bother me while Galaxy S7 and S8 do.

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...

AgentX20 Anyone had some or all of their wisdom teeth removed? Im checking possible TMJ connection with this. I think we must have something in common. Of course it can be genetic brain issue, but maybe not.

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.

KM Yeah, my wisdom teeth came out at 19. Light problems started at 37. Not related, I'd say.
