Apple 21.5 iMac Desktop Computer (Late 2013) (Refurbished)

Design

Impossibly Thin

Just a mere 5mm at its edge the iMac has up to 40 percent less volume than the 2011 iMac. Using an advanced welding method called friction-stir welding Apple was able to join the front and the back of the iMac together directly

Re-Engineered Screen

The display on the iMac is no longer behind the cover glass but its actually right up against it. The LCD itself is 5mm thinner than before and using an advanced process called full lamination Apple was able to eliminate a 2mm gap between the LCD and the glass. Full lamination has a second major benefit that it eliminates reflection of light off the LCD panel and off the back of the displays cover glass. Apple also reduced reflection off the front of the glass without compromising color quality. Instead of applying an antireflective coating to the glass in the conventional way Apple adapted a process commonly used on camera lenses called plasma deposition which results in 75 percent reduction in reflectivity and vibrant accurate colors

True-to-Life Colors

None of these innovations would matter much if the iMac display didnt deliver vivid true-to-life color. Which is why Apple puts every single display through an exacting color-calibration process using three state-of-the-art spectroradiometers: one to measure gamma one to measure white point and one to check the work of the other two. This equipment is tuned to meet color standards recognized around the world for precision and accuracy

A Display of Excellence

The 21.5 screen of the iMac features an innovative display design which reduces reflection by 75 percent. In addition the LCD now sits right up against the glass allowing the picture so content looks crisp and clear. The display also uses in-plane switching (IPS) technology resulting in a bright picture with vivid true-to-life color from a wide 178° viewing angle. The LED backlighting also offers instant-on uniform brightness

Eco-Friendly

The iMac is energy efficient using up to 50 percent less energy in the idle state with the display on. And its hardware components work hand in hand with the operating system to conserve even more power. The environmentally friendly iMac design is free of many harmful toxins including mercury arsenic BFRs and PVC. Its also made from materials such as aluminum and glass which are more likely to be recycled and reused

Performance

4th Generation Haswell Intel Core i5 Processor

The iMac houses a 4th generation Haswell Intel Core i5 processor. Its quad cores can reach a stock speed of 2.7GHz. It can also be overclocked up to 3.2GHz thanks to Intel Turbo Boost 2.0 technology. The 4th-gen Haswell Intel processor uses low voltage for better energy efficiency while still providing fast performance

Integrated Intel Iris Pro Graphics

The iMac features 4th-generation Intel Iris Pro graphics which can deliver discrete graphics-level performance

Storage

The iMac comes with a 1TB hard drive so you have plenty of room to save your photo albums iTunes music libraries Full HD 1080p movies and more

Thunderbolt

Thunderbolt technology is phenomenally fast. It features two 10-Gbps channels for data transfer. Thats up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. But beyond speed Thunderbolt gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt devices - including two Apple Thunderbolt Displays - to a single port. And since Thunderbolt is based on DisplayPort technology Mini DisplayPort devices like the Apple LED Cinema Display plug right in too

USB 3.0

With USB 3.0 you can connect your external hard drive transfer large files in seconds instead of minutes. Every iMac comes with four USB 3.0 ports - with speeds up to 10 times faster than USB 2.0 - and you can connect all your USB-compatible devices including your iPhone iPad iPod or digital camera

Wi-Fi and Bluetooth

The 802.11ac/a/b/g/n wireless technology automatically locates your Wi-Fi network so you can connect and start surfing the web printing and streaming your music wirelessly. Bluetooth 4.0 wireless technology is also built in so you can connect accessories such as a wireless keyboard and mouse
