4k resolution: A full guide to 4K

A full guide to 4K resolution : definition, types, screen formats, practical uses, and why it matters for video quality and display tech. We would like to show you a description here but the site won’t allow us. What is 4K resolution ? 4K resolution refers to a horizontal display resolution of around 4,000 pixels. The higher pixel count in 4K offers a clearer and more detailed image. This makes it good for TV, gaming, and professional video editing. Resolution is as old as the television—which means it was first demonstrated in 1927. Although 3840 × 2160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably since not all 4K resolutions are 2160 pixels tall, and not all 2160p resolutions are ≈4000 pixels wide.
