5K resolution

5K resolution is horizontal resolution of about 5,000 pixels. The most common 5K resolution is 5120 × 2880, which has an aspect ratio of 16:9 and is about 14.7 million pixels (just over seven times as many pixels as 1080p Full HD). This resolution is typically used in computer monitors, and is not a standard format in digital television and digital cinematography, which feature 4K resolutions and 8K resolutions.

In comparison to 4K UHD (3840 × 2160), the 16:9 5K resolution of 5120 × 2880 offers 1,280 extra columns and 720 extra lines of display area, an increase of 33.33% in each dimension. This additional display area can allow 4K content to be displayed at native resolution without filling the entire screen, which means that additional software such as video editing suite toolbars will be available without having to downscale the content previews.

As of 2016, the world uses 1080p as the mainstream HD standard. However, there is a rapid increase in media content being released in 4K and even 5K resolution. Online streaming services such as Netflix and Amazon Video launched videos in 4K resolution in 2014 and are actively expanding their collection of videos in 4K resolution. As 4K content becomes more common, the usefulness of 5K displays in editing and content creation may lead to a higher demand in the future.

On April 14, 2008, Red Digital Cinema Camera Company launched one of the first cameras capable of video capture at 5K resolutions. RED EPIC uses the Mysterium X sensor which has a resolution of 5120 × 2700 and can capture at a framerate of up to 100 fps. Cameras with 5K resolution are used occasionally for recording films in digital cinematography.

Some photographic still cameras such as DSLRs can exceed 5K resolution when capturing still images, but not when capturing video. For example, the Canon EOS 6D announced in September 2012 has a maximum resolution of 5472 × 3648 pixels (around 20 megapixels in a 3:2 aspect ratio) which is used for high resolution still images, but it can only capture video at a maximum of 1920 × 1080.
