(Ars Technica) – A few weeks ago, Apple updated its iMac desktop line with “Retina” displays—an Apple marketing term used to denote LCDs with a pixel density high enough that individual display elements are invisible to the unaided eye at typical viewing distances. On Apple’s iPhones, the “Retina” moniker means a PPI of at least 300; for MacBook Pro portables, it means about 220. The new iMac’s 27″ 5120×2880 LCD panel has a PPI of 218, putting it just below the 15″ MacBook Pro’s 220 PPI.
Those numbers translating into a stunning screen is unsurprising, and now that I’ve got one on my desk to play with, I’ll absolutely add my voice to the chorus of other reviewers saying that the new iMac looks amazing. I haven’t yet attached a colorimeter to the display and gone to town—that’s coming in the next few days—but here’s the color space information right out of the box.
