The 27″ iMac Desktop Computer from Apple is an all-in-one desktop computer with an ultra-slim unibody design. Measuring at just 5mm at its edges, the iMac has 40% less volume than its predecessor. The body of the iMac isn’t the only thing that got thinner. The LCD display is now 5mm thinner, and Apple also removed a 2mm gap between the LCD panel and the glass to save even more space. The 27″ widescreen display features LED backlighting for vibrant, accurate color. With in-plane switching (IPS) technology, the iMac has a wide 178° viewing angle. The screen has a 16:9 aspect ratio and Full HD 2560 x 1440 native resolution, supported by an nVIDIA GeForce GTX 675MX graphics card with 1GB discrete GDDR5 memory.
