What is the resolution of 2560×1440

2560×1440 is 2K resolution. 2560×1440 resolution means that the number of horizontal pixels is 2560 and the number of vertical pixels is 1440. 2K refers to a resolution level where the horizontal resolution of the screen or content reaches about 2000 pixels; all screens with a horizontal resolution of about 2000 pixels fall into the 2K category.

2560×1440 is 2K resolution.

2K is a general term that refers to a resolution level where a screen or content has a horizontal resolution of approximately 2000 pixels. The most standard 2K resolution is 2048×1024, and digital cinema projectors mainly use this resolution.

2560×1440 resolution means that the number of horizontal pixels is 2560 and the number of vertical pixels is 1440. All screens with a horizontal resolution of around 2000 pixels fall into the 2K category.

Because the 16:9 ratio is the international standard for high-definition video specifications, the common format of 2K resolution in video production, display and other fields is 2560×1440 (16:9) (WQHD ). The traditional movie 2K resolution is 2048×1080.

Extended knowledge:

Resolution, also known as resolution and resolution, can be subdivided into display resolution and image resolution rate, printing resolution, scanning resolution, etc. Resolution determines how fine the details of a bitmap image are. Typically, the higher the resolution of an image, the more pixels it contains, the clearer the image, and the better the quality of the print. At the same time, it will also increase the storage space occupied by the files.

Different resolutions: 640*360 is smooth resolution; 960*540 is SD resolution; 1280*720 is HD resolution; 1600*900 is ultra-HD resolution; 1920*1080 is 1080P resolution.

Resolution is the precision of the screen image, which refers to the number of pixels that the monitor can display. Usually, the number of pixels in each row is multiplied by the number of pixels in each column, for example:

• The resolution is 1024×768, which means the monitor can display 768 rows and 1024 columns, and a total of 786432 pixels can be displayed;

• The resolution is 640×480, which means the monitor can display 480 Rows, 640 columns, a total of 307,200 pixels can be displayed.

Since the points, lines and surfaces on the screen are all composed of pixels, the more pixels the monitor can display, the more detailed the picture will be, and the information that can be displayed in the same screen area There are also more, so resolution is one of the very important performance indicators.

Comparison of 2K resolution and 1080P:

• The resolution of 1080p (Full HD or FHD) is Although 1920x1080 has a horizontal resolution of nearly 2000 pixels, in most media, including web page production, image production, books, etc., 1080p and 2K resolutions are considered different resolutions rather than the same.

• According to DCI official reference materials, DCI and related industry standards do not consider 1080p to be 2K and 4K resolutions.

• Although 1080p is not standard 2K, because 1080p has a horizontal resolution of nearly 2000 pixels, 1080p can be classified as 2K rather than 1K.
