The 21.5" iMac Desktop Computer is an all-in-one desktop computer with an ultra-slim unibody design. 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 21.5" 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 1920 x 1080 native resolution, supported by a dedicated NVIDIA GeForce GT 750M graphics card with 1GB of GDDR5 memory.
