Migraine triggered by the monitor? Possibly. The problem is that it only ever became more severe when using this monitor. I even took a 36 hour break from the monitor, let the migraine play itself out, and used my old setup. I felt perfectly fine, and after about 6 hours of using that setup I switched back to the Asus. Well, I'm in pain again.
Initially I thought it was the flickering from lowering brightness on the monitor (PWM), but after the 36 hour break I kept my brightness at 100% which is flicker-free from what I researched. I dimmed my computer screen and adjusted colors using Flux and DimScreen, so the monitor is no brighter than my other one. I'm simply at a loss as to what could be causing it. I know many will suggest I get an eye exam, and I plan on doing so as soon as I can, but I figured why not list my current monitors and see what people with more experience think.

A little background... 20/20 vision, never had an eye sight issue in my life, although, I haven't received an eye exam in two years. I plan on going to get one soon after this experience. I was diagnosed with migraines at 16, so that is also a possible issue. On top of the 22 inch and 19 inch displays above I also use an iPad regularly to read for school. My eyes will strain slightly after 3-4 hours of reading in a very dark room on default iPad brightness settings (which is pretty bright, and reminds me I should turn it down ), but nothing simply turning off the iPad and 5 minutes of rest can't fix.
Could the LED backlight at 100% brightness (but dimmed through other means) cause such serious issues? I know everyone is different, but these are pretty extreme side effects.
Any experiences with this monitor (or similar ones) and these type of issues are more than welcome. Considering I'm studying computer science, and want to program for a living this is something I am very keen on figuring out. I'll be purchasing a Benq XL2420T since it is supposedly flicker-free at all brightness levels, and I figured why the hell not just to test if it was an Asus issue.
