What determines how sharp a screen image looks?
Show answer & explanation
Answer: Pixel density packed into the display
Pixel density packed into the display ✓ — Correct! Resolution measures pixels (tiny colored dots) packed into a screen. More pixels in the same area means finer detail—4K (3840×2160) has 4× more pixels than 1080p (1920×1080). Phones need high pixel density for close viewing; TVs can use fewer pixels per inch since you sit farther away.
Speed of the graphics processor — Wrong. GPU speed affects how fast images render, not how sharp they look. Sharpness depends on pixel count—more pixels packed into the display means more detailed images.
Brightness level of the backlight — Wrong. Brightness affects how luminous the screen appears, not image sharpness. Sharpness comes from pixel density—how many tiny dots make up the image. More pixels = finer detail.
