Until I saw it next to my new 30" ACD, my 3 year old Del 2407WFP seemed just fine to me. I never noticed that it has definite yellow-cast. I've tried to get rid of it with Colorsync adjustments and with hardware adjustments on the display itself, but no luck.
I got chastised in the Mac Peripherals forum for suggesting (OK, making a blanket statement
) that Apple displays come pre-calibrated to SWOP standards (i.e., they render colors accurately out of the box), and that Dells and HPs come calibrated to impress gamers (i.e., they produce exaggerated colors). I will qualify this statement by saying that I have never seen a 30" Dell or HP display, but I have read plenty on online reviews that indicate these displays are not as color accurate out of the box as Apple 30" ACDs.
