I've never had sore eyes before. I have had this monitor for ten days and have seriously sore eyes. I spent four hours on the computer last night and woke with eyes still sore. I would also be grateful for advice.
Once again, his setup is identical, just different is the monitor.
my eyes start to hurt really bad, pretty fast, (talking couple of hours), where as on my old one i could do a 24+hour sitting and not feel anything
Someone else says:
Have this problem since 2011... I went to doctor cause of that, he said everything is ok with your eyes, but problem remained..
After 3 years of gathering "experience " from watching all sorts of monitors i can "almost" narrow problem to : IPS technology,IPS glow, very hard coating they glue to screen which produces grainy picture (you should see dell ultrasharp monitor through my eyes ) , blue light which LED produces , backlight frequency
