What does native resolution describe in display technology?

• A. The actual number of pixels a display can show
• B. The refresh rate
• C. The color depth
• D. The physical size in inches

Answer: (A)

The thing being tested is how many pixels the screen contains in its visible grid. Native resolution is the exact pixel grid the display is built to show, described by width by height (for example, 1920×1080). It represents how many individual picture elements the screen can display at once. When content uses that same resolution, each content pixel maps directly to a screen pixel, so the image is sharp and clear. If you view content at a different resolution, the display must scale it to fit, which can blur fine details and reduce sharpness. This concept is distinct from refresh rate (how many times the image updates per second), color depth (how many colors per pixel), and physical size (the screen’s diagonal), which are separate aspects of display performance.
