2K is a common display resolution. A screen's resolution explains how many pixels it has in width x height format (the more pixels, the sharper the image). A monitor or display is considered 2K if its width falls in the 2,000-pixels range.
The Digital Cinema Initiatives (DCI), a group of motion picture studios that creates standards for digital cinema, defines Standard DCI 2K resolution as 2048 x 1080 pixels. But you'll rarely see this resolution when buying a PC monitor or choosing a laptop. You'll often find 2K displays with a 2560 x 1440 resolution. However, that resolution is officially considered Quad HD (QHD). As such, many monitors and gaming laptops claim their resolution as 2K/QHD.
Common Monitor Resolutions
| 5K | 5120 x 2880 |
| 4K | 3840 x 2160 (typical monitor resolution); 4096 x 2160 (official cinema resolution) |
| Ultra HD (UHD) | 3840 x 2160 |
| QHD aka WQHD aka 1440p | 2560 x 1440 |

Barty1884 I don't think 2K really has any relevance in monitor marketing - even when it is mentioned, it's mentioned in conjunction with something else.Reply
There should only really be
HD/720p / 921,600 pixels
FHD/1080p / 2,073,600 pixels
WQHD / 1440p / 3,686,400
4K / 3840x2160 / 8,294,400 pixels
.....and wide-screen variants.
In that format, pixel count ~doubles per 'step' up, and is fairly clear/straightforward.
2K is marketing blurb for TVs (where pixel count increased <10%), that has been misappropriated into the monitor space, IMO. -
marie811 2K displays are those whose length falls in the 2,000-pixels range. The Digital Cinema Initiatives (DCI), a group of motion picture studios that creates standards for digital cinema, defines Standard DCI 2K resolution as 2048 x 1080.Reply
