What Is 4K Resolution?

Many screen-based electronic products sold on the market today are labeled with "4K," but you may not understand the definition of 4K. This term refers to image resolution. A 4K screen resolution, also known as Ultra High Definition (UHD), is four times the resolution of standard High Definition (1080P).

4K resolution refers to a display resolution with approximately 4000 pixels along the horizontal axis. The most common 4K resolution is 3840 x 2160 pixels, totaling 8,294,400 pixels. The increase in pixel count provides sharper, clearer images.

What are the applications of 4K resolution?

4K resolution is widely used. Now, it's mostly used for high-end monitors, various computer displays, televisions, laptops, digital cameras, and other display devices.

4K resolution is also used in various technological fields, such as the movies we watch, which are shown in 4K theaters, as well as in gaming, photography and videography, digital signage, medical imaging, Computer-Aided Design (CAD), and 3D modeling, among others.

Of course, currently, there are no smartphones or tablets with Ultra High Definition displays. As 4K content becomes more common, more and more devices may support this new standard.
