After nearly a year of speculation, Apple has just officially unveiled the new 4K 21.5-inch iMac. The new iMac released alongside an updated 5K iMac brings Broadwell processors to the line, and uses a custom red-green phosphor LED-backlit panel with a full DCI-P3 color gamut. The new panel gives a 25 percent larger color space over previous solutions, on top of a resolution of 4096 x 2034, encompassing 9.4 million pixels in total.
