Which resolution is achieved by a 4K display?

A 4K display typically achieves a resolution of 3840 x 2160 pixels. This resolution is commonly referred to as Ultra High Definition (UHD). It offers four times the pixel resolution of 1080p (1920 x 1080), providing a significant increase in detail and clarity. The 3840 x 2160 resolution is especially beneficial for larger screens, where the increased pixel density allows for a more immersive viewing experience without noticeable pixelation at closer viewing distances.

The other common resolution associated with 4K is 4096 x 2160, known as DCI 4K. While both resolutions fall under the broader 4K category, for consumer displays, the 3840 x 2160 format is the standard. This distinction is important, as it reflects the most widely accepted format for consumer televisions and monitors, making it the typical resolution reference when discussing 4K technology.

In summary, the correct answer highlights the resolution standard most commonly recognized for general consumer devices, contributing to better picture quality and a superior viewing experience.
