What is Screen Resolution?
Screen resolution refers to the number of pixels displayed on your screen in both horizontal and vertical directions. Each pixel is a tiny square of color, and together they form the images you see. A higher resolution means more pixels, resulting in sharper and more detailed visuals. Common examples include 1920×1080 (Full HD) and 3840×2160 (4K).
