I don't know about dithering, but analog VGA has, in most cases, noise, which also induces some jittering
Temporal Dithering Sensitivity - My Solution
13 days later
Does anyone know whether Ditherig is supporting Intel 8th-gen processors? I think there was a very terse/generic note about Coffee Lake being supported and the install seemed to work. However, I'm still trying to tell the difference between settings on/off, and seem to continue to be symptomatic.
Using an i7-8700k and MSI 1070. White screens still look a bit funny to me and I think symptoms are starting to appear after an hour or so of usage 
Was really hoping that the temporal dithering thing was the solution. Not sure I like this monitor on any device so I need to give one other one a go, but still disappointed and hoping there's an easy answer, yet.
I don't think it does for newer CPU/GPU pairs, but I may be wrong. I couldn't observe any banding or other difference with ditherig enabled on 7th/8th-gen W10 computers. It worked fine on my 8-years old machine. It might also be a problem with W10, as this older computer was running Windows 7.

Regarding monitors, using Windows 10, can it be problematic buying a monitor with 1,07 billion colors?
I have a 27'' Samsung with 16,7 million colors. I found no problem with Windows 10. I think that a billion colors might use temporal dithering/FRC to achieve those colors. What do you guys think? Maybe it's safe to buy a 16,7 million color monitor?
Also what does it means, that on specification a monitor has the following:
Brightness (Typical): 250cd/m2
Brightness (Min): 200cd/m2
Brightness min? The minimum brightness the monitor can achieve? Almost the same has the tipical brightness? Or is a uniformity spec?

For those who want to check FRC in monitors, you can check on this site:
https://www.displayspecifications.com/en
Mine: Samsung SA850D is true 8 bit. No FRC.
ryans Dell U3417w has FRC, it has a true 8-bit panel but it uses FRC to achieve 10 bit. 10 bits (8 bits + FRC)
Lets go on forum of NVidia and post it every day so it can be always on top. Ask for a dithering option.

One question:
Does ditherg disable dithering on intel chips, for all monitors? Or just true 8-bit panel? The ones
with 6-bit+FRC are also disable or the panel of the monitor dither?

JTL How can we tell whether a monitor has FRC? I installed ditherig on my laptop, and see no difference. There is no banding when I look at gradients, and my eye strain is still terrible. If FRC is the issue, how can I address it? I have a Lenovo Flex 5 with with a MX130 graphics card.
I am so happy to have found this community because I felt like I was going crazy when screens without PWM were started causing me pain.
Afsvys It can be hard to know if a monitor has dithering. Here's some advice.
- Try and find a list of specifications. If it lists color depth as something like 6+2 bit that is FRC/dithering.
- If you know the model number of the PANEL inside the monitor there is a site called PanelLook that might be have the same info, but it's not always accurate.
- TFTCentral sometimes lists if a monitor used dithering/FRC.
It's honestly easier to get a monitor without dithering. Most IPS panels above 1080p, all BenQ VA panels I think, they don't use dithering.

Just for reference - I have updated the original post with my current setup which is usable for 8 hours per day. I'm still extremely sensitive to temporal dithering, and would still love a proper solution to the problem.
Really hope this helps someone else as it has changed my life having a workable setup - I don't feel jealous seeing other people able to work for hours on Macbooks any more..

si_edgey Cheers for the update! Glad to hear you've found a system that works for you.
Markus Do you fell any discomfort using latest Firefox or Chrome browser with your setup? Is watching YouTube with any of that browsers comfortable for you?
I've found Microsoft Edge to be the most comfortable web browser by far compared to FF and Chrome.

diop What is more comfortable about Edge? The best for me so far is FF with the Dark Background and Light Text extension. I use a dark theme in my OS.
Forgot to mention my screen is pushed back, my fonts are scaled up in my window manager, and my browser zoom is at 140%. With multiple monitors pushed away, one can enjoy ample screen real estate with these comfortable parameters.
