It's a work computer, so I can't downgrade the OS.
It has an identical video card as I have in a Win 7 computer that is used without eye strain, so I'm prety sure Windows 10 is the issue.
Windows 10 appears to render type and color completely differently. This seems to cause the monitor to act in a way that causes eye strain. I'm currently working on getting admin access to the machine so I can tweak more settings and see if I can resolve the issue.
diop I doubt even the most sympathetic IT admin would downgrade one person to an earlier W10 revision.
Yeah, I tried to stay on the corporate Win 7 build as long as possible but eventually the company had to upgrade me due to security policy. My ADA request to remain on Windows 7 was rejected as being unreasonable due to lack of adherence to security policies.
For my home PC I don't have windows 10 and never will, that OS is so freaking beyond terrible I can't believe it. I am on Windows 7 until it becomes unsupported and I will then be moving to Linux when forced to. I have used various Linux builds with XFCE shell without issues.
ensete What CPU and GPU are you using in your PC? Does Linux cause eye strain without the XFCE shell? I tried the latest version of ubuntu and mint, both caused eyestrain with a ryzen 5/RX550 build... however that might be due to the RX550. I now have an old HD8500 GPU which worked fine on windows 7 but causes strain on windows 10. Unfortunately I haven't had a chance to try it with any linux distos.
ensete I'm running 7 at home too but have had success with 8.1, might be worth a try at least for home use?
Funny thing is I've never had a good time with Linux. I remember trying Ubuntu live in the late 00's and had (looking back) similar symptoms to now, so dithering of some sort has been a thing on *nix long before Windows I imagine.
Since nouveau etc is open-source hopefully there's a solution for Linux soon. I'll keep my fingers crossed.
Gurm Possibly. I've turned bad displays into good displays by loading the correct ICC profile. I've also had good displays hurt me when displaying certain colors. But I've never gotten triggered by a color in real life, which leads me to believe it's something the monitor is doing in order to display that color that is causing the issue
Still waiting for admin access but one thing I notices, switching from a DVI connecter to an old HD15 connector seemed to help a little
ensete I didnt notice this article before - https://en.m.wikipedia.org/wiki/Subpixel_rendering
it shows that when subpixel rendering is involved, the letters float and dont stay put. Putting too much workload on people with preexisting eye cond. like heterophoria.
Im gonna meet with one physicist soon and do tests in a lab with microscope and high speed camera on good and bad devices. He works in led development and is really interested in the topic. Its already been done here, but now I hope to replicate it more precisely.
I am also curious why my iphone 7 is ok now with reduced white point, but without it gives really bad pain. Hopefully the tests will show.
It also seems subpixel rendering is driven by graphic cards and not os - 
I found this link from some months ago where Windows 10 had a bug that caused all monitors and graphics card to have strong banding on gradients: https://www.eizoglobal.com/support/compatibility/software/problem_windows10_may_2019_update/index.html
I think this is further proof that they are doing something unnecessary with the graphics output on the OS level, independent of monitors and graphics cards.
I've just tryed to upgrade my notebook and my desktop pc from the 1809 to the 1909 and i can't use it! Someone else have found some problems with the last upgrade?
Outside of a workplace y'know y'all don't have to use Win 10..

That's true however not for much longer. Windows 7 updates stop next month and Windows 8.1 in January 2023.
I also think given that W10 has been out for nearly 5 years, it's the principle that by now we should be able to use this OS without issues. Maybe something behind the scenes changed in W10, this could explain why when testing my NUC a few months back I had problems.
