What is 4K resolution?

You likely have heard the phrase “4K” before, but you may not understand the 4K definition. The term refers to image resolution. Also known as Ultra High Definition (UHD), 4K resolution is four times as great as standard high definition (1080P).

Whereas a standard high definition picture contains 1,080 pixels along the vertical axis and 1,920 pixels along the horizontal axis for a total pixel count of 2,073,600, 4K resolution doubles these figures. The resolution gets its name from the number of pixels along the wide axis, which at 3,840, is nearly 4,000 in total. The total pixel count of a 4K picture is 8,294,400 (more than 8 megapixels). This increase in the number of pixels provides for a sharper, clearer picture.

When did 4K resolution become the standard?

YouTube started accepting 4K video uploads in 2010 and in 2014, several media broadcasters started offering 4K content for the first time in wide release (Netflix being one of them). A slightly higher resolution version of 4K (known as 4K DCI) has also been seen in movie theaters since 2011. The 4K standard for television and Internet content, Ultra High Definition, is relatively new but will likely supersede standard HD content in the very near future.

What types of electronics use 4K?

A wide range of computer monitors, laptops, and televisions now support 4K resolution. Also, still cameras with video functionality and dedicated video cameras can record at 4K resolution. Currently, no smartphones or tablets are available with an Ultra High Definition picture. As 4K content becomes commonplace, more and more devices will likely support this new standard.

What types of 4K products does Lenovo offer?

Lenovo offers a few options for individuals seeking a picture with unparalleled resolution, clarity, and vibrancy. Lenovo Y-series laptops includes UHD options, some with up to a 15.6-inch 4K screen, and desktop users can take advantage of offerings in the ThinkVision line of computer monitors, some with features such as infinity glass, touch-sensitive buttons, USB connectivity, and dual speakers.
