kammerer So main point that root cause could be in neck muscle and blood channels that restrict proper blood feeding.
You adopt the same posture on any computer workstation so unless there's a physical reason I don't know how bloodflow could be affected by flickering.
One thing that is clear is that we are a minority. Nobody in my immediate family has issues, nor do friends IRL or people I know via Social Media.
However I am the only person I know of who has strabismus (heterotropia) and a significantly high prescription with prism correction (at least -8 in each eye). In my life I would say I've encountered less than 5 people with visible eye misalignment. My eye doctor has always said I am a 'unique case' - well, we all like to be unique at something 😀.
It's not as if there are swarms of people having seizures or complaining of headaches using the latest tech, if there was a severe epidemic with users across the globe these issues would have been resolved by now.
I am using a 2019 Dell U2419H and have been using it for 2 months now. It's absolutely fine - I can use it for hours and hours without any issues. I am using my 2010 PC, though. This monitor is PWM-free and TUV-certified for low blue light, so I still had to carefully consider my monitor choice, but it isn't out of anybody's price bracket, and I'm using it fine. I do understand there is an even smaller minority with sensitivites to LED, but CCFL-tech is still perfectly usable for the next decade or so.
Another post has info on heterophoria, but that accounts for 10% of the population so I would have expected more people to be complaining about new technology.
I've had an MRI in the last 5 years, it came back normal. I've had many eye checks due to other issues and the eyes are healthy, and my prescription hasn't changed since I was a teenager.
Anyways, taking action; It's process of elimination to find the point of failure. I think Linux is a good place to start. Somebody out there has to know the kernel inside-out and will be able to explain how Linux DE's render the desktop, what type of dithering/artifacts are used, and how they can be removed. Linux is transparent, so a dithering/artifact free Linux could be a reality tomorrow, if we find the right programmer. If we then test and can all certify that we can run the 'fixed' distro on our good HW without issue, then we test on the bad HW. If the known good Linux distro on our good setup then has strain on the bad, then we're looking at a VBIOS issue or something baked into the HDMI output of new tech. Surely it's as simple as that, either the Driver/OS or VBIOS is producing this painful output. VBIOS could be the tricky issue - however if we KNOW we are running software which does not produce extra artifacts, we have eliminated any other root cause and can pressurise Nvidia et al with these findings.
