vaz I get symptoms in minutes on offensive machines. Super old 15yo stuff is fine as long as I can stay awake so it grates me when people say simply wrong stuff like "all screens cause strain and its CVS etc". That makes no sense when an old screen and old OS is fine with ZERO problems for 16 hours or more. My butt hurts but not my eyes or head or neck.
This is me. I am fine with LED too, but I make sure it's PWM-Free. I'm using the Dell U2419H, had it hooked up for three months now and is absolutely fine. YMMV, of course.
I am convinced it's an issue in the rendering, or rather, a big bug in the rendering, causing extra noise/colour changes where there doesn't need to be. Many articles I am seeing online now support this theory.
I am out of work too, and can't use any PC's made after 2011/2012. Phones are tolerable for say 5 minutes but I can't watch videos etc on Phones now, those days are over for me.
I'm just glad I'm not the only person with these symptoms, otherwise I would seriously start to question myself 🙂.
Ultimately I just want the option (from GPU stage to driver/OS to disable dithering). This is trivial to implement as we're not talking about a new feature, just changing a 1 to 0 in code or something similar. Hopefully we get somewhere re: Linux.
