What Is 4K Resolution? A Basic Definition

4K resolution is a common display resolution, often known as 2160p and UHD. The resolution of a display describes how many pixels it has in width x height format. The more pixels on a screen, the sharper the image should be. The Digital Cinema Initiatives (DCI), an organization of motion picture studios that develops digital cinema standards, defines 4K resolution as 4096 x 2160 (opens in new tab), but this resolution is uncommon in consumer goods. PC monitors, laptops, and TVs labeled as 4K resolution typically have a resolution of 3840 x 2160. However, this resolution is officially referred to as Ultra HD (UHD). UHD/ 4K resolution monitors are frequently seen.
