So I have been using my new 24" Dell (I know) for the past few days and have noticed that my eyes get really tired within a few hours or less. I am used to CRTs where I could use it for over 8 hours straight with no problems. Even other lcds I have used didn't seem to affect me. So my question is, anyone else experience increased eye strain/headache with a large lcd display? Wonder if my eyes just need to get used to it.
