LED backlighting display
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.
More pixels & Better picture
The new 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.
Stunning from every angle
The new iMac display looks great from any seat in the house, thanks to a premium display technology called in-plane switching (IPS). IPS gives you a bright picture with excellent color consistency — even if you’re viewing the display from the side.
More memory and storage
The new iMac has 4GB of 1066MHz DDR3 memory standard, with room in its four SO-DIMM slots for up to 16GB, so you can run more applications simultaneously. And with a Serial ATA hard drive up to 2TB, feel free to load up on photos, videos, and music.
High-speed 802.11n wireless technology is built into iMac. And with Time Capsule or the AirPort Express Base Station, every computer in every room can wirelessly connect to iMac, the Internet, and each other.³ Over this network, everyone can print, surf the web, and play music on iTunes through your home stereo — wirelessly.
iMac banishes desktop clutter completely with a wireless keyboard to go with the wireless Magic Mouse. This low-profile keyboard takes up less desk space — 24 percent less — than larger keyboards. There’s no numeric keypad, so you can place your mouse comfortably next to the keyboard.
Wireless Magic Mouse
Forget the mouse as you know it. Every iMac comes with the wireless Magic Mouse: the world’s first Multi-Touch mouse. Use it once and you’ll wonder how you ever used anything else. There’s no scroll ball, no clunky wheel, no cord, and no visible button.
