"Apple weds high-res 4K visuals into its sleek 5mm thin 21.5"" 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"" 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.

For ports, the iMac has dual Thunderbolt 2 ports (which also double as Mini DisplayPorts) and four USB 3.0 ports. You'll be able to connect with various compatible components. If you would rather go wireless with your peripherals, you can use Bluetooth 4.0 technology where compatible.

<strong>Retina 4K Display</strong>
Whether your iMac is in your studio, living room, or kitchen, the display is the focal point. With a 4096 x 2304 resolution, this iMac features 9.4 million pixels, which allows for crisp, clear text and support for 4K photos and videos. The IPS panel allows for wider viewing angles so more people can enjoy the Retina 4K display without having to crowd around it. The Retina 4K display also features a wider color gamut for true-to-life color. Moving beyond the typical sRGB display, this iMac features a P3 color gamut, achieved by shifting the Retina 4K display from standard white LEDs to advanced red-green phosphor LEDs. Now all three colors - red, green, and blue - are more equally represented and show off real-world color with more balance and precision.

<strong>Thin Design</strong>
The iMac with Retina 4K display maintains its 5mm profile, which is up to 40 percent less volume than the 2011 iMac. Using an advanced welding method called friction-stir welding, Apple was able to join the front and the back of the iMac together directly.
