Unbelivable, I went to a computer store today... A few monitors were powered on, looking at their screens and my eyes started to hurt. And I was good for a few hours again...
Anyway, like I've said already, the problem is to find a good seller that knows what is he selling. A guy, which was obiously boring and I quite annoyed him, told me that all monitors are LED, I asked if they are all edge lit, he say I guess, expensive ones aren't, sorry, I will need to look the specs.... Well, he didn't look for it...
So I'm stuck again. Just send an email to another store that promotes counseling for monitors etc. I hope they've ever heard for eye-strain, flickering, LED, edge lit etc.
