In terms of display screens, what does resolution refer to?

Resolution in the context of display screens specifically refers to the number of pixels that are used to create the image on the screen in each dimension. It is typically expressed as the width and height in pixels, for example, 1920x1080, which indicates that the display has 1920 pixels horizontally and 1080 pixels vertically. This pixel density directly impacts the clarity and detail of the images displayed on the screen; higher resolution generally results in sharper and more detailed visuals.

Understanding resolution is fundamental to evaluating display quality, as it directly correlates with how much detail can be shown. Other aspects such as brightness, color depth, and refresh rate are indeed important characteristics of a display, but they pertain to different aspects of the viewing experience rather than the basic structural composition defined by resolution.
