With a 5K (5120 x 2880) screen resolution, this iMac provides one billion colors and 500 nits of brightness. The Retina 5K display also features the wider P3 color gamut, which provides a larger color space that shifts away from standard white LEDs to red-green phosphor LEDs that more equally represent red, green, and blue. And with more available colors, the images will appear more vivid and reveal greater detail, with more balance and precision. The display is further enhanced by True Tone technology for a more natural viewing experience
