Resolution comparison chart for 16:9 aspect ratio

5K resolution refers to a horizontal resolution of the order of 5,000 pixels, forming the image dimension of 5120×2880 (aspect ratio 16:9) which gives rise to a total of about 14.7 million pixels. This resolution is usually seen in computer monitors, as compared to digital television and digital cinematography which feature 4K resolution and 8K resolution.[1] 5K is a display resolution that is considered mid-range in ultra high definition television (UHDTV) and is between 4K resolution and 8K resolution.

In comparison to 4K resolution, 5K resolution offers approximately 1,000 extra horizontal pixels and 700 extra vertical pixels of display area. In other words, while a 4K medium is being displayed, this additional display area can effectively provide space for opening of another web browser or video editing software. This allows side-by-side viewing and editing of a 4K medium.[2]

As of 2015, the world uses 1080p as the mainstream HD standard. However, 4K resolution is inching closer to becoming the new standard by 2017 due to the constant demand for better visuals,[3] but the relevance and feasibility of such a high resolution standard is debatable.[4]

However, there is a rapid increase in media content being released in 4K resolution and even 5K resolution. Online streaming services such as Netflix and Amazon Video launched videos in 4K resolution in 2014[5] and are actively expanding their collection of videos in 4K resolution.

History

Samsung 105 inch Ultra HD television

First Camera with 5K

On April 14, 2008, one of the earliest camera with 5K resolution, known as RED EPIC series, was launched by Red Digital Cinema Camera Company. RED EPIC uses the Mysterium X sensor which features 5K resolution (5120 x 2700) and the capability to capture up to 100FPS.[6] Cameras with 5K resolution are used occasionally for recording films in digital cinematography.

First TV with 5K

In CES 2014, Samsung first demonstrated its 105" Samsung Smart UN105S9 UHD TV. While Samsung lists the UN105S9 UHD TV as a 4K curved OLED TV, it actually has native resolution of 5120*2160 (21:9 aspect ratio) which qualifies as ultra-high-definition 5K resolution with 11 megapixels. It is also the world's first TV to combine all three cutting-edge technologies: OLED panel, curved design and ultra-high-definition resolution.[7]

First Monitor with 5K

On September 5, 2014, Dell unveiled 'the world's first' monitor with 5K resolution. This monitor features a 27-inch display and resolution of 5,120 x 2,880, as well as 218 PPI.[8] Subsequently in October 2014, Apple released a new iMac with same resolution and size, 5,120 x 2,880 resolution and 27 inch display. The difference is that the 27" iMac is not a monitor, but a mid-range PC and cannot be used as an external monitor by another computer.[9][10]

Compatible Graphic cards

In order to fully utilize monitors with 5K resolution, the graphic card used must support native 5K resolution. Some graphic cards that support native 5K resolution are AMD Radeon R9 M295X (used in 27" iMac with 5K resolution)[12] Nvidia GeForce GTX Titan Z and AMD R9 Fury X.[15]
