LED backlighting. One bright idea.
Full brightness with no waiting. That’s the big advantage of the LED-backlit iMac display. Unlike most displays that take time to warm up before they reach maximum brightness, an LED- backlit display is instantly on and uniformly bright. LED backlighting also gives you greater control over screen brightness. So you can finely tune the iMac display to suit the ambient light in even the dimmest room.
More pixels. Better picture.
iMac offers some prime pixel real estate. The 21.5-inch, 1920-by-1080 display has 17 percent more pixels than the previous 20-inch iMac. The 27-inch, 2560-by-1440 display has a whopping 78 percent more pixels than the 21.5-inch iMac. And a 1000:1 contrast ratio gives you more vibrant colors and blacker blacks. All that in a widescreen display with a 16:9 aspect ratio — the same as an HD TV.
