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
The new iMac offers some prime pixel real estate. The 21.5-inch, 1920-by-1080 display has 17 per cent more pixels than the previous 20-inch iMac. The 27-inch, 2560-by-1440 display has a whopping 78 per cent more pixels than the 21.5-inch iMac. And a 1000:1 contrast ratio gives you more vibrant colours and blacker blacks. All that in a widescreen display with a 16:9 aspect ratio — the same as an HD TV
Now available with quad-core power
The 21.5-inch and 27-inch iMac models offer fast Intel Core 2 Duo processors up to 3.33GHz. Quad-core power comes to the 27-inch iMac with a 2.66GHz Intel Core i5 processor or 2.8GHz Intel Core i7 processor. Four cores deliver up to 2x faster performance for just about everything you do: managing your photos, editing HD video, even playing graphics-intensive 3D games.¹ And since Mac OS X Snow Leopard is designed to take full advantage of Intel dual- and quad-core architectures, you get theb fastest performance possible.
