GamePyre published a Dell 24-inch S2409W Monitor Review.
Quote from the review: "Movies, games and even 2-D applications perform and look superbly on this monitor. I did not notice any glitches, flickers or distorted images. But besides the image looking sharp and great I did notice another difference with the S2409W Dell monitor. Personally, I associate this difference with the size difference, but I did notice that my eyes are not as tired and as dry at the end of the day, and maybe it is just a coincidence, but since I got this monitor I do not remember having a single headache (I've only had it for 2 weeks though). So far I'm very satisfied with this monitor."
