Apple weds high-res 4K visuals into its sleek 21.5" iMac with Retina 4K Display (Early 2019). In addition to its 4096 x 2304 screen resolution, its display offers 1 billion colors at 500 nits of brightness. The Retina 4K display also features the wider P3 color gamut, which provides a larger color space by utilizing red-green phosphor LEDs that uniformly represent red, green, and blue. And with more available colors, images will appear more vivid and reveal greater detail, with more balance and precision.
The iMac's processing power has been upgraded with an 8th-gen 3.6 GHz Intel Core i3 Quad-Core processor as well as DDR4 RAM. Graphics are powered by a dedicated AMD Radeon Pro 555X graphics card.
