Apple weds high-res 5K visuals into its sleek, 5mm thin, mid 2017 27" iMac with Retina 5K Display. With a 5120 x 2880 screen resolution, this iMac provides 1 billion colors and 500 nits of brightness, which is 43% brighter than the previous model. The Retina 5K display also features a wider color gamut. Using a P3-based color gamut, the Retina 5K display provides a larger color space that more equally represents red, green, and blue, as compared to standard sRGB displays. And with more available colors, the images will appear more vivid and reveal greater detail, with more balance and precision.
