The screen resolution or display resolution determines the clarity and number of items displayed on your computer screen. It’s measured horizontally and vertically in pixels. At lower screen resolutions, such as 800 x 600, texts and images appear larger but less items fit on the screen. At higher resolutions, such as 1920 x 1080, more items fit on the screen, with smaller and sharper appearances.
