iMac 21.5

Big, beautiful displays.

21.5-inch and 27-inch displays.

Today’s iMac has come a long way from the first 15-inch iMac. Take one look and you’ll see just how far. A 21.5-inch or 27-inch display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and what’s onscreen. Movies, TV shows, websites, photos — everything looks stunning on the 16:9 widescreen iMac display.

LED backlighting.

When a display has more pixels, you need to push more light through them to achieve the best picture possible. LED backlighting in iMac does exactly that, with remarkable brightness and efficiency. Because the LED backlight doesn’t take up much space, the iMac enclosure stays thin — even with all the high-performance components inside.

High resolution.

The 21.5-inch iMac features 1920-by-1080 HD resolution. Apple engineers could simply have stretched that resolution up and out for the 27-inch iMac. Instead, they took the display well beyond HD with 2560-by-1440 resolution. That’s 78 percent more pixels than the 21.5-inch iMac.

 IPS technology.

The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. Whether you’re sitting in front of the display or standing off to the side, you’ll get a great picture with superb color.

All-in-one simplicity.

Evolution of iMac.It was a great idea then, and it’s a great idea now. The all-in-one design of the first flat-panel iMac cleaned up the desktop. It put everything you need — display, processor, graphics card, hard drive, optical drive, memory, and more — inside one simple enclosure. New technology on the inside makes the new iMac a worthy addition to the all-in-one dynasty.

Seamless enclosure.

While you’ll find a collection of ports on the back of iMac, you won’t find much else. A seamless, precision-forged enclosure makes the back one continuous aluminum surface. And there’s only one cord: the power cord.

Cool, quiet components.The widescreen iMac display allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultraquiet. The result of all this tinkering with heat and sound? A system that operates at 18 decibels when idle — so quiet, you hardly know it’s on.

Details that matter.

Edge-to-edge glass.

The glass that surrounds the LED-backlit display wraps around the edge of the aluminum enclosure.

Tapered pedestal.

Another victory over clutter, the finely tapered aluminum pedestal practically disappears on the desktop.

Redesigned speakers.

New speakers deliver louder, clearer sound with better bass response and less distortion.

Displays like nothing you’ve ever seen.

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.

Stunning from every angle.

The 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 — even if you’re viewing the display from the side.

The new performance standard.

New Intel Core processors across the line.

All iMac models now include processors from the blazing-fast Intel Core series, featuring an advanced processor architecture that helps set new performance benchmarks for iMac. The 21.5-inch models and one 27-inch model come standard with a dual-core Intel Core i3 processor starting at 3.06GHz. For even more performance, choose the top-of-the-line 27-inch iMac with a quad-core Intel Core i5 at 2.8GHz or optional Intel Core i7 at 2.93GHz. Four cores make just about everything you do faster: managing your photos, editing HD video, even playing graphics-intensive 3D games. And since Mac OS X Snow Leopard is designed to take full advantage of Intel dual- and quad-core architectures, you get the fastest performance possible.

Revved-up graphics.

Every iMac comes with high-performance discrete graphics processors from AMD that make games run smoother, photos load faster, and pro applications work better. Learn more about iMac performance

Plenty of memory and storage.

The new iMac has 4GB of DDR3 memory standard — now running even faster at 1333MHz — with room in its four SO-DIMM slots for up to 16GB, so you can use more applications simultaneously. And with a Serial ATA hard drive up to 2TB,1 feel free to load up on photos, videos, and music.

Add an ultrafast solid-state drive.

To give your iMac a real performance boost, configure your 27-inch iMac on the Apple Online Store with an optional 256GB solid-state drive. You can choose it as your only drive or have it installed in addition to the built-in hard drive, allowing you to store the operating system, critical applications, and important files on the solid-state drive and your other files on the hard drive. Because solid-state drives have no moving parts, the computer can access data at over twice the speed of hard drives. Which makes starting up your iMac and launching applications faster than you ever thought possible.

Built-in Wi-Fi.

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.2 Over this network, everyone can print, surf the web, and play music on iTunes through your home stereo — wirelessly.
