I'm not sure if it's just me, but do any of you have eye strain after staring at the screen for hours? I never had this issue on my 20" cinema display or any other LCD screen for that matter (I use a 21" lcd at work daily without any issues). But when I work on my 30", my eyes start to burn after a few hours. I'm starting to think that it's because my room isn't well lit enough and the display is so bright. And I also can conclude that it's this display because I can use my 19" CRT (100hz) for hours without any issues as well. It's only when I use the 30" that my eyes start to hurt.
