Apple iMac 27-inch - Thunderbolt PC Review
On the outside, the iMac 27-inch (Thunderbolt) looks just like its aluminum and glass predecessors. It has the same huge 27-inch 2,560-by-1,440 resolution display, which is formatted with a 16:9 aspect ratio and is higher resolution than the 1,920 by 1,080 required for true 1080p HD. The display is so bright that Apple added a new ambient light sensor to auto-dim the screen, so users in brightly lit studios can keep their eyes from straining when a cloud obscures the sun or if someone draws the drapes over the window. The glass panel protecting the LED-backlit LCD display is glossy, one of the few nits against the iMac 27-inch (Thunderbolt). I'd like to see a matte finish option for graphics professionals who want it. Speaking of graphics professionals, Apple color calibrates each display before shipping it to the final user. Color calibration won't necessarily be a big consideration for the average consumer, but it's a boon to the graphics artist who makes her living with the iMac.
