With Retina display, text appears sharper than ever, videos are unbelievably lifelike and you can see new levels of detail in your photos. The 21.5-inch iMac is available with the all-new Retina 4K display featuring an amazing 4096 x 2304 resolution and 9.4 million pixels, 4.5 times more than the standard 21.5-inch iMac display. Every 27-inch iMac features a Retina 5K display, the world’s highest resolution all-in-one display with a stunning 14.7 million pixels, 7 times more pixels than an HD display. With a Retina display now on the 21.5-inch iMac and every 27-inch iMac, iMac with Retina display is more affordable than ever.
The new Retina displays feature a wider colour gamut that brings more brilliant and true-to-life colors to your desktop. With standard sRGB-based displays, many of the colours you see in real life never make it to your screen. The new Retina 5K and 4K displays feature a wider P3-based colour gamut that provides a 25 percent larger colour space, and with more available colours, images are more vivid, reveal even greater detail and appear more lifelike than ever.

The new 21.5-inch iMac with Retina 4K display features a fifth-generation Intel Core processor and enhanced Intel Iris Pro Graphics. Two Thunderbolt 2 ports now come standard on all iMacs and deliver up to 20Gbps data transfer speeds for external drives and high-performance peripherals.
