What is Screen Resolution?

Screen Resolution is the quantity of pixels on a display or in a camera sensor (specifically in an alphanumeric image). An advanced resolution means more pixels and more pixels provide the ability to display more graphic 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 colors of these tiny square components.

 

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. Therefore, the importance of the other parameter that we publish – pixel density, which is measured in pixels-per-inch (ppi).

If you’re relating two screens of the same size but with diverse 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.
