Apple weds high-res 4K visuals into its sleek 5mm thin 21.5 inch iMac with Retina 4K Display. With a 4096 x 2304 native resolution, this iMac provides 9.4 million pixels, which is 4.5 times more than the Full HD 1080p 21.5 inch iMac. The Retina 4K display also features a wider color gamut. Using a P3-based color gamut, the Retina 4K display provides a 25% larger color space than standard sRGB displays. And with more available colors, the images will appear more vivid and reveal greater detail.
