So I've now got my mid-2012 MBP connected via Mini DisplayPort to an HP ZR2440W 24" 1900x1200 IPS monitor. Beautiful results, but I have to admit that I'm taken aback by how "wet" or "electric" the reproduced image is. Nothing's wrong with the colors, and taking down the brightness/contrast helps, but coming from the world of PCs attached to external displays (once owned a white MacBook but never a desktop Mac), I feel like the screen is going to eat my face off or something. It seems aggressive somehow. My eyes don't feel strained per se, just a little flummoxed. Is this simply an OS X thing? Different font smoothing may have something to do with it, as the text looks more gelatinous than I'm used to, if that makes sense. On the other hand, the picture on the MBP's internal HR AG display does seem "drier" and less aggressive. At any rate, if there's tweaking to be done, I haven't the foggiest where to start.
