What is Screen Resolution?

Screen resolution refers to the number of pixels on a display or in a camera sensor (specifically in a digital image). A higher resolution means more pixels and more pixels provide the ability to display more visual information. Screen resolution is the number of pixels. The image on your computer screen is built up from thousands or millions of pixels. The screen creates the image you see by changing the colours of these tiny square elements.

The screen resolution tells you how many pixels your screen can display horizontally and vertically. It’s written in the form 1080 x 720. In this example, the screen can show 1,080 pixels horizontally, and 720 vertically.

Names and Sizes of screen resolutions

High Definition (HD) > 1280 x 720

Full HD, FHD  > 1920 x 1080

2K, Quad HD, QHD > 2560 x 1440

4K, Ultra HD  > 3840 x 2160

Resolution does not refer to the physical size of the display, camera sensor or image. For example, two displays with the same resolution can have different physical dimensions. Hence the importance of the other parameter that we publish – pixel density, which is measured in pixels-per-inch (ppi).

If you’re comparing two screens of the same size but with different resolutions, the screen with the higher resolution (that’s the one with more pixels) will be able to show you more of what you’re working on, so you don’t have to scroll so much.
