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.
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.
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.
